15 - CHAPTER 2 FORECAST OF ELECTRIC POWER DEMAND AND ENERGE CONSUMPTION OVERVIEW Te information presented in te following Sedules 2, 3 and 4 represents PEF s istory and foreast of ustomers, energy sales (GW), and peak demand (MW). Assumptions were made to predit a foreast wit a 5/5 probability, or te most likely senario. PEF s ustomer growt is expeted to average 1.5 perent between 29 and 218, wi is less tan te ten-year istorial average of 2. perent. Slower population growt, based on te latest projetion from te University of Florida s Bureau of Eonomi and Business Resear (BEBR), and eonomi onditions less favorable for te ousing/onstrution industry, inluding, for example, tigter mortgage redit availability and iger property taxes and insurane rates, results in a lower ustomer projetion wen ompared to te iger istorial growt rate. Tis translates into lower projeted energy and demand growt rates from istori rate levels. Net energy for load (NEL), wi ad grown at an average of 2.2 perent between 1999 and 28, is expeted to inrease by 1.5 perent per year from 29 to 218. A lower ontribution from te wolesale jurisdition, wose billled energy grew an average of 8.2 perent between 1999 and 28, results in lower expeted system growt going forward at just.3 perent. Retail billed energy, wi grew at a 1.6 perent average rate istorially, is expeted to grow 1.7 perent over te next ten-year period. Te iger projeted growt rate is solely due to a return to a more typial weater pattern in te foreast. Summer net firm demand is expeted to grow at an average of 1.4 perent per year during te next ten (1) years. Tis is lower tan te 1.9 perent growt rate experiened trougout te last ten (1) years. Again, slower ustomer growt and lower ontribution from te wolesale jurisdition are expeted going forward. Also, iger load management apability for te projeted period olds down growt in firmi peak demand. Progress Energy Florida, In. 2-1

16 ',n,n,.-,a, - Summer net firm retail demand is expeted to grow at an average of 1.7 perent per year during te next ten (1) years; tis is lower tan te 2. perent average annual growt rate experiened trougout te last ten-year period. Te istorial growt perentage was driven by a period of strong ustomer growt and delining load management apability wile te projetion period assumed weaker growt and return to iger load management apability..a ENERGY CONSUMPTION AND DEMAND FORECAST SCHEDULES SCHEDULE 2.1, 2.2 and DESCRIPTION History and Foreast of Energy Consumption and Number of Customers by Customer Class History and Foreast of Summer Peak Demand (MW) History and Foreast of Winter Peak Demand (MW) History and Foreast of Annual Net Energy for Load (GW) Previous Year Atual and Two-Year Foreast of Peak Demand and Net Energy for Load by Mont - P - P.

28 FORECASTING METHODS AND PROCEDURES INTRODUCTION Aurate foreasts of long-range eletri energy onsumption, ustomer growt, and peak demand are essential elements in eletri utility planning. Aurate projetions of a utility s future load growt require a foreasting metodology wit te ability to aount for a variety of fators influening eletri energy usage over te planning orizon. PEF s foreasting framework utilizes a set of eonometri models to aieve tis end. Tis setion will desribe te underlying metodology of te ustomer, energy, and peak denland foreasts inluding te prinipal assumptions inorporated witin ea. Also inluded is a desription of ow Demand-Side Management (DSM) impats te foreast, te development of ig and low foreast senarios and a review of DSM programs. Figure 2.1, entitled Customer, Energy and Demand Foreast, gives a general desription of PEF s foreasting proess. Higligted in te diagram is a disaggregated modeling approa tat blends te impats of average lass usage, as well as ustomer growt, based on a speifi set of assumptions for ea lass. Also aounted for is some diret ontat wit large ustomers. Tese inputs provide te tools needed to frame te most likely senario of te ompany s future demand..n FORECAST ASSUMPTIONS Te first step in any foreasting effort is te (development of assumptions upon wi te foreast is based. Te Finanial Servies Department develops tese assumptions based on disussions wit a number of departments witin PEF, as well as troug te resear efforts of a number of external soures. Tese assumptions speifl major fators tat influene te level of ustomers, energy sales, or peak demand over te foreast orizon. Te following set of assumptions forms te basis for te foreast presented in tis doument. Progress Energy Florida, In. 2-14

30 GENERAL ASSUMPTIONS 1. Normal weater onditions for energy sales are assumed over te foreast orizon using a salesweigted tirty-year average of onditions at seven ( 7) weater stations aross Florida (Saint Petersburg, Tampa, Orlando, Winter Haven, Gainesville, Daytona Bea, and Tallaassee). For kilowatt-our sales projetions, normal weater is based on a istorial tirty-year average of te servie area weigted billing montl degree-days. Seasonal peak demand projetions are based on a tirty-year istorial average of system-weigted temperatures at time of seasonal peak at te Tampa, Orlando, and Tallaassee weater stations; te oter weater stations are not used in developing te istori average beause tey lak te istori ourly data needed for peak-weater normalization. 2. Te population projetions produed by te Bureau of Eonomi and Business Resear (BEBR) at te University of Florida as ]publised in Florida Population Studies Bulletin No. 15 (Mar 28) provide te basis for development of te ustomer foreast. An update to inlude a downward revision to State-wide growt made by te BEBR in July 28 was inorporated to apture te latest trends being witnessed in te PEF servie area. State and national eonomi assumptions produed by Eonomy.Com in teir national and Florida foreasts (September 28) are also inluded. 3. Witin te PEF servie area, te pospate mining industry is te dominant setor in te industrial sales lass. Four (4) major ustomers aounted for 32 perent of te industrial lass MW sales in 28. Tese energy intensive ustomers mine and proess pospate-based fertilizer produts for te global marketplae. Te supply and demand for teir produts are ditated by global onditions tat inlude, but are not limited to, foreign ompetition, nationalntemational agriultural industry onditions, exange-rate flutuations, and international trade pats. Load and energy onsumption at te PEF-served mining or emial proessing sites depend eavily on plant operations, wi are eavily influened by tese global as well as te loal onditions. After years of exess mining apaity and weak produt priing power, te industry as onsolidated down to just a few players in time to take advantage of better market onditions. In addition, a weaker U.S urreny value on te foreign exange as elped te industry in two (2) ways. First, Amerian f m ommodities ave Progress Energy Florida, In. 2-16

31 beome more ompetitive overseas wi as ontributed to iger rop prodution at ome. Te demand for orn-based etanol as also inreased farm areage. Bot impats are expeted to ontinue to maintain and inrease te demand for fertilizer produts. Seond, a weak U.S. dollar results in U.S. fertilizer produers beoming more prie ompetitive relative to foreign produers. Going forward, energy onsumption is expeted to inrease in te near term, as a new mine operation is expeted to open. A signifiant risk to tis projetion lies in te volatile prie of energy, wi is a major ost of bot mining and produing pospori fertilizers. Te energy projetion for tis, industry assumes no major redutions or sutdowns of operations in te servie territory. Tis inludes any ange in output fkom self-owned generation failities, wi remove load &om PEF generation failities. 4. PEF supplies load and energy servie to wolesale ustomers on a "full", "partial", and "supplemental" requirement basis. Full requirements (FR) ustomers' demand and energy is assumed to grow at a rate tat approxirnates teir istorial trend. Contrats for tis servie inlude te ities of Bartow, Cattaoolee, Mt. Dora, Quiny, Williston, and Winter Park. Partial requirements (PR) ustomer load is assumed to reflet te urrent ontratual obligations refleted by te nature of tle stratified load tey ave ontrated for, plus teir ability to reeive dispated energy from power marketers any time it is more eonomial for tem to do so. Contrats for PR servie inludedl in tis foreast are wit te Florida Muniipal Power Ageny (FMPA), Reedy Creek Utilities, TECO Energy, Seminole Eletri Cooperative, In. (SECI) and te ities of New Smyrna Bea, Tallaassee, Gainesville and Homestead. PEF's ontratual arrangement wit SECI inludes a "supplemental" servie ontrat ( 1983 ontrat) for servie over and above stated levels tey ommit to supply temselves. Tis ontrat as been renegotiated and will ange from a supplemental nature sale to a "stratified apaity" sale onsisting of a base, peaking and system average piees beginning in 214 wen te term of tis ontrat expires in Deember 213. A firm ontrat wit SECI for stratified intermediate servie, wil inludes bot 45 MW (Otober 1995 ontrat) and an additional 15 MW in 212, is ontained in tis projetion. Anoter ontrat wit varying levels of stratified demands ranging from 75 MW to 3 MW will be served in 29 and a Progress Energy Florida, In. 2-17

32 FR ontrat wi will ommene in 21 and last troug te foreast orizon, are also ontained in tis foreast. Finally, an agreement to provide interruptible servie at a SECI metering site as also been inluded in tis projetion. 5. Tis foreast assumes tat PEF will sui:ssfully renew all future franise agreements. 6. Tis foreast inorporates demand and energy redutions from PEF's dispatable and non- dispatable DSM programs required to imeet te approved goals set by te FPSC. 7. Expeted energy and demand redutilons from ustomer-owned self-servie ogeneration failities are also inluded in tis foreast. PEF will supply te supplemental load of selfservie ogeneration ustomers. Wile PEF offers "standby" servie to all ogeneration ustomers, te foreast does not assume an unplanned need for power at time of peak. 8. Tis foreast assumes tat te regulatory environment and te obligation to serve our retail ustomers will ontinue trougout te foreast orizon. Regarding wolesale ustomers, te ompany does not plan for generation resoures unless a long-term ontrat is in plae. Current FR ustomers are assumed to renew teir ontrats wit PEF exept tose wo ave given notie to terminate. Current PR ontrats are projeted to terminate as terms rea teir expiration date. Deviation from tese assumptions an our, based on information provided by te Portfolio Management Department.,A.- SHORT-TERM ECONOMIC ASSUMPTIONS Te eonomi outlook for tis foreast was developed in mid-28 as te omebuilding market ontinued its signifiant downturn. Tis market sift as ontributed to te lak of PEF ustomer growt..ci Te foreast was developed in a year of eonomi instability. Reord ig oil pries dereased onsumption, terefore assisting in slowing, eonomi growt. Initial laims for unemployment insurane ad inreased signifiantly and Staie and National employment levels ad dereased ea mont. Te Federal Reserve Board ommened a series of interest rate uts in response to te Progress Energy Florida, In. 2-18

33 eonomi anges. Te early stages of te serious redit risis ad just begun. In Florida, te rising ome forelosures and falling ome values as well as a large inventory of unsold omes is expeted to old down new onstrution for most of 29. A signifiant inrease in eletri pries was assumed as utilities needed to pass-troug iger fuel osts. Tis would result in a derease in average ustomer usage. However Florida real estate values ave dereased enoug to no longer be onsidered over-valued. Tis is expeted to result in a return to more normal levels of new resident migration and ome buying. LONG-TERM ECONOMIC ASSUMPTEONS Te long-term eonomi outlook assumes tlat anges in eonomi and demograpi onditions, as well as tenologial ange in te eletri utility industry, will follow a trended beavior pattern. Te main fous involves identifying tese trends. No attempt is made to predit business yle flutuations or rapid penetration of a signifiant tenologial breaktroug impating eletri utility energy sales during tis period. Population Growt Trends Tis foreast assumes Florida will experiene slower new resident migration and population growt over parts of te long term, as refleted in te BEBR projetions. Florida's limate and low ost of living ave istorially attrated a major sare of te retirement population from te eastern alf of te United States. Tis will1 ontinue to our primarily beause te soon to be retiring baby-boom generation will inreasle te size of available retirees apable of moving to te Sout. Working against tis signifiani: trend will be several aesteti and eonomi fators. First, te enormous growt in population and orresponding development of te 198s, 199s and early 2s made portions of Florida less desirable and less affordable for retirement living. Tis pereived diminised quality of retiree life, along wit inreasing ompetition from neigboring states, will ause a sligt deline in Florida's sare of tese prospetive new residents over te long term. Seond, and to a lesser extent, tere is a lingering fear for safety and expense from urriane damage. Progress Energy Florida, In. 2-19

34 Eonomi Growt Trends Sine te beginning of te Post-91 1 period, Florida experiened a 198s-style population explosion and rapid servie-setor job reation. Te State as benefited greatly from generational lows in interest rates, wi, along wit investors' unfriendly attitude toward te equity markets, set te stage for a tremendous surge in ome onstrution. Te national level of omebuilding in 24-26, set an all time reord. Tis growt produed strong gains in bot te onstrution industry and servie-produing setors of te Florida eonomy. However, te period will reflet a reord slump. Nationwide, te amount of ousing setor redit as redued. Te availability of money making its way into te mortgage market as signifiantly dereased as te risk to lenders as risen. U.S. onsumer debt as inreased, sine te 21 eonomi downturn. Wit te lak of inome growt, redit being unavailable, and redued wealt, a growing U.S. savings rate ours as well as a return to trend-level growt. As te eonomy begins a new ylial upturn, a sort period of demand reated by retirees wo were unable to sell teir omes and unusuallly low mortgage rates sould begin by 21. A more sustained level of ustomer growt nearing te istorial average will our. Te istorially low interest rates are expeted to produe an inrease in ome oupany. More importantly, te deline in ome pries as returned te ousing market to a more typial level wile providing a more affordable produt. Going forward, tese and oter impats indiate tat a more level growt pattern is expeted. Te foreast assumes stable growt in real eletriity prie over te long term. Tat is, te ange in te nominal prie of eletriity per kw over time is expeted to be lose to te overall rate of inflation. Tis also implies tat fiiture fuel prie esalation will trak at or below te general rate of inflation trougout te foreast orizon. Progress Energy Florida, In. 2-2

35 . A..- Real personal inomes are assumed to inrease trougout te foreast period tereby boosting te average ustomer's ability to purase eletriity. As inomes grow faster tan te prie of eletriity, onsumers, on average, will remlain inlined to purase additional eletri applianes and inrease teir utilization of existing endl-uses. FORECAST METHODOLOGY Te PEF foreast of ustomers, energy sales, and peak. demand is developed using ustomer lass-speifi eonometri models. Tese models are expressly designed to apture lassspeifi variation over time. By modeling ustomer growt and average energy usage individually, subtle anges in existing ustomer usage are better aptured as well as growt from new ustomers. Peak demand models are projeted, on a disaggregated basis as well. Tis allows for appropriate andling of individual assumptions in te areas of wolesale ontrats, load management, and interruptible servie. A 'C *A ENERGY AND CUSTOMER FORECAST In te retail jurisdition, ustomer lass models ave: been speified sowing a istorial relationsip to weater and eonomi/demograpi indiators using montly data for sales models and annual data for ustomer models. Sales are regressed against "driver" variables tat best explain montly flutuations over te istorial sample period. Foreasts of tese input variables are eiter derived internally or ome from a review of te latest projetions made by several independent foreasting onerns. Te external soures of data inlude Moody's Eonomy.Com and te University of Florida's Bureau of Eonomi and Business Resear (BEBR). Internal ompany foreasts are used for projetions of eletriity prie, weater onditions, and te lengt of te billing mont. Normal weater, wi is assumed trougout te foreast orizon, is based on te 3-year average of eating and ooling degree-days by mont as measured at several weater stations trougout Florida for energy projetions and temperatures around te our of peak for te firm retail demand foreast. Projetions, of PEF's demand-side management (onservation programs) are also inorporated as redutions to te foreast. Speifi setors are modeled as follows : F Progress Energy Florida, In. 2-2 I

36 Residential Setor Residential kw usage per ustomer is modeled as a funtion of real Florida personal inome, ooling degree-days, eating degree-days, te real prie of eletriity to te residential lass and te average number of billing days in ea sales mont. Tis equation aptures signifiant variation in residential usage aused by eonomi yles, weater flutuations, eletri prie movements, and sales mont duration. Projetions of kw usage per ustomer ombined wit te ustomer foreast provide te foreast of total residential energy sales. Te residential ustomer foreast is developed by orrelating annual ustomer growt witl PEF servie area population growt. County level population projetions for te twenty-nine (29) ounties, in wi PEF serves residential ustomers, are provided by te BEBR. F. Commerial Setor Commerial MW energy sales are foreast based on ommerial setor (non-agriultural, nonmanufaturing and non-governmental) employment, te real prie of eletriity to te ommerial lass, te average number of billing days in ea sales mont and eating and ooling degree-days. Te measure of ooling degree-days utilized ere differs sligtly from tat used in te residential setor refleting different temperature base sensitivities,,wen eating and ooling load beome observable. Commerial ustomers are projeted as a ntion of te number of residential ustomers served. Industrial Setor Energy sales to tis setor are separated into two sub-setors. A signifiant portion of industrial energy use is onsumed by te pospate mining industry. Beause tis one (1) industry is a tirtytwo (32) perent sare of te total industrial lass, it is separated and modeled apart fiom te rest of te lass. Te term "non-pospate industrial" is used to refer to tose ustomers wo omprise te remaining portion of total industrial lass sales. Bot groups are impated signifiantly by anges in eonomi ativity. However, adequately explaining sales levels requires separate explanatory variables. Non-pospate industrial energy sales are modeled using Florida manufaturing employment and a Florida industrial prodution index, te: real prie of eletriity to te industrial lass, and te average number of sales mont, billing days. Progress Energy Florida, In. 2-22

37 Te industrial pospate mining industry :is modeled using ustomer-speifi information wit respet to expeted market onditions. Sine tis subl-setor is omprised of only four (4) ustomers, te foreast is dependent upon information reeived fiom diret ustomer ontat. PEF industrial ustomer representatives provide: speifi pospate ustomer information regarding ustomer prodution sedules, inventory levels, area ]mine-out and start-up preditions, and anges in self-servie generation or energy supply situations over te foreast orizon. Street Ligting Eletriity sales to te street and igway ligting lass las varied up and down but overall as remained flat for te past fifteen (15) years. A sligt deline is expeted as improvements in effiieny are projeted. Te number of aounts, wi as dropped by two-tirds in te past fourteen (14) years due to most transferring to publi autority ownersip, is expeted to deline rter before leveling off in te intermediate term. A simple time-trend was used to projet energy onsumption and ustomer growt in tis lass. Publi Autorities Energy sales to publi autorities (SPA), ornprised mostly of government operated servies, is also projeted to grow wit te size of te servie area. Te level of government servies, and tus energy use per ustomer, an be tied to te population base, as well as to te state of te eonomy. Fators affeting population growt will affet te need for additional governmental servies (i.e. publi sools, ity servies, et.) tereby inreasing SPA energy usage per ustomer. Government employment as been determined to be te best indiator of te level of government servies provided. Tis variable, along wit eating and ooling degree-days (lass speifi), te real prie of eletriity and te average number of sales mont billing days, results in a signifiant level of explained variation over te istorial sample period. Interept sift variables are also inluded in tis model to aount for te large ange in sool-related energy use in te billing monts of January, July, and August. Te SPA ustomer foreast is projeted linearly as a funtion of a timetrend. Progress Energy Florida, In. 2-23

38 Sales for Resale Setor Te Sales for Resale setor enompasses all firm sales to oter eletri power entities. Tis inludes sales to oter utilities (muniipal or investor-owned) as well as power agenies (rural eletri autority or muniipal). Seminole Eletri Cooperative, In. (SECI) is a wolesale, or sales for resale, ustomer of PEF on bot a supplemental ontrat basis and ontrat demand basis. Under te supplemental ontrat, PEF provides servie for tose energy requirements above te level of generation apaity served by eiter SECI's own failities or its firm purase obligations. Montly supplemental energy is developed using an average istlorial load sape of total SECI load in te PEF ontrol area, subtrating out te level of SECI "ommitted" apaity from ea our. Beyond supplemental servie, PEF as several agreements wit SECI to serve various types of stratified demand levels deemed by teir resoure planners as neessary..- Te muniipal sales for resale lass inludes a number of ustomers, divergent not only in sope of servie, (i.e. full or partial requirement), but also in omposition of ultimate onsumers. Ea ustomer is modeled separately in order to aurately reflet its individual profile. Several of te ustomers in tis lass are muniipalities wose full energy requirements are supplied by PEF. Te full requirement ustomers' energy projetions grow at a rate tat approximates teir istorial trend. Sine te ultimate onsumers of eletriity in tis setor are, to a large degree, residential and ommerial ustomers, it is assumed tat teir use patterns will follow tose of te PEF retail-based residential and ommerial ustomer lasses. PEF serves partial requirement servie (PR) to muniipalities su as New Smyrna Bea (NSB), Homestead, Gainesville and Tallaassee, and oter power providers like FMPA and Reedy Creek Utilities In ea ase, tese ustomers ontrat wit PEF for a speifi level and type of demand needed to1 provide teir partiular eletrial system wit an appropriate level of reliability. Te energy foreast for ea ontrat is derived using its istorial load fators were enoug istory exists, or typial load fators for a given type of ontrated stratified load. Te energy projetions for FMPA also inlude a "losses servie ontrat" for energy PEF supplies to FMPA for transrnission losses inurred wen "weeling" power to teir ultimate ustomers in PEF's transmission area. Tis projetion is based on te projeted n Progress Energy Florida, In. 2-24

39 'A,A -..-.A. requirements of te aggregated needs of tlne ities of Oala, Leesburg, Busnell, Havana, and Newbeny. PEAK DEMAND FORECAST Te foreast of peak demand also employs a disaggregated eonometri metodology. For seasonal (winter and summer) peak demands, as well as ea mont of te year, PEF's oinident system peak is separated into five (5) major omponents. Tese omponents onsist of potential firm retail load, onservation and load management program apability, wolesale demand, ompany use demand and interruptible demand.,a Potential firm retail load refers to projetions of PEF retail ourly seasonal net peak demand (exluding te non-firm interruptible/urtaible/standby servies) before te umulative effets of any onservation ativity or te ativation of PEF's Load Management program. Te istorial values of tis series are onstruted to sow te size of PEIF's firm retail net peak demand assuming no utility-indued onservation or load ontrol ad taken plae. Te value of onstruting su a "lean" series enables te foreaster to observe and orrelate te underlying trend in retail peak demand to total system ustomer levels and oinident weater onditions at te time of te peak witout te impats of year-to-year variation in onservation ativity or load ontrol redutions. Seasonal peaks are projeted using istorial seasonal peak data regardless of wi mont te peak ourred. Te projetions beome te potential retail demand projetion for te mont of January (winter) and August (summer) sine tis is typially wlen te seasonal peaks our. Te nonseasonal peak monts are projeted te same as te seasonal peaks, but te analysis is limited to te speifi mont being projeted. Energy onservation and diret load ontrol estimates are onsistent wit PEF's DSM goals tat ave been approved by te FPSC. Tea8e estimates are inorporated into te MW foreast. Projetions of dispatable and umulative non-dispatable DSM are subtrated from te projetion of potential firm retail demand resulting in a projeted series of retail montly peak demand figures one would expet to our. Sales for Resale demand projetions represent load supplied by PEF to oter eletri utilities su as SECI, FMPA, and oter eletri distribution ompanies. Te SECI supplemental demand Progress Energy Florida, In. 2-25

40 projetion is based on a trend of teir istorial demand witin te PEF ontrol area. Te level of MW to be served by PEF is dependent upon te amount of generation resoures SECI supplies itself or ontrats fiom oters. An assumption is made tat SECI will sift teir level of self-serve resoures to meet teir base and intermediate load needs. For Partial Requirement demand projetions, ontrat levels ditate te level of montly demands. Te Full Requirement muniipal demand foreast is estimated for individual ities using istorially trended growt rates. PEF "ompany use" at te time of system peak is estimated using load resear metering studies and is assumed to remain stable over te freast orizon. as it as istorially. Te interruptible and urtailable servie (IS and CS) load omponent is developed fiom istori trends, as well as te inorporation of speifi information obtained from PEF's large industrial aounts by aount exeutives. Ea of te peak demand omponents deslribed above :is a positive value exept for te DSM program MW impats and IS and CS load. Tese impats represent a redution in peak demand and are assigned a negative value. Total system firm peak demand is ten alulated as te aritmeti sum of te five (5) omponents..- CONSERVATION PEF's DSM performane is presented in te following tables, wi ompare te onservation savings atually aieved troug PEF's DSM programs for te reporting years of 25 troug 28 wit te Commission-approved onservations goals. On August 9, 24, te FPSC issued a PAA Order approving new onservation goals for PEF tat span te ten-year period from 25 troug 214, as well as a new DSM Plan for PEF tat was speifially designed to meet te new onservation goals (Doket 431-EG, Order No. PSC PAA-EG). On January 5, 27, te FPSC issued a PAA Order approving tirtynine (39) additional DSM measures and two (2) residential programs, wi will serve to inrease te demand and energy savings available troug PEF's DSM Plan (Doket 6647: Consummating Order PSC-7-17-CO-EG making Order PSC TRF-EG effetive and final).

71 ,r., -.,,.,...,n.n INTEGRATED RESOURCE PLANNIN(G OVERVIEW PEF employs an Integrated Resoure Planning (IRP) proess to determine te most ost-effetive mix of supply- and demand-side alternati ves tat will reliably satisfy our ustomers' future demand and energy needs. PEF's IRP proess inorporates state-of-te-art omputer models used to evaluate a wide range of future generation alternatives and ost-effetive onservation and dispatable demand-side management programs on a onsistent and integrated basis. An overview of PEF's IRP Proess is sown in Figure 3.1. Te proess begins wit te development of various foreasts, inluding demand and energy, fuel pries, and eonomi assumptions. Future supply- and demand-side resoure alternatives are identified and extensive ost and operating data are olleted to enable tese to be modeled in detail. Tese alternatives are optimized togeter to determine te most ost-effetive plan for PEF to pursue over te next ten (1) years to meet te ompany's reliability riteria. Te resulting ten-year plan, te Integrated Optimal Plan, is ten tested under different relevant sensitivity senarios to identify varianes, if any, wi would warrant reonsideration of any of te base plan assumptions. If te plan is judged robust and works witin te orporate framework, it evolves as te Base Expansion Plan. Tis proess is disussed in more detail in te following setion titled "Te Integrated Resoure Planning (IRP) Proess". Te Integrated Resoure Plan provides PEF wit substantial guidane in assessing and optimizing te Company's overall resoure mix on bot te supply sidle and te demand side. Wen a deision supporting a signifiant resoure ommitment is being developed (e.g. plant onstrution, power purase, DSM program implementation), te Company will move forward wit diretional guidane from te IRP and delve mu M 'er into te speifi levels of examination required. Tis more detailed assessment will typially address very speifi tenial requirements and ost estimates, detailed orporate finanial onsid.erations, and te most urrent dynamis of te business and regulatory environments.

73 THE INTEGRATED RESOURCE PLANNING (IRP) PROCESS Foreasts and Assumptions Te evaluation of possible supply- and demand-side alternatives, and development of te optimal plan, is an integral part of te IRP proess. Tese steps togeter omprise te integration proess tat begins wit te development of foreasts and olletion of input data. Base foreasts tat reflet PEF's view of te most likely future senarios are developed, along wit ig and low foreasts tat reflet alternative future senarios. Computer models used in te proess are brougt up-to-date to reflet tis data, along wit te latest operating parameters and maintenane sedules for PEF's existing generating units. Tis establises a onsistent starting point for all furter analysis. - - Reliability Criteria Utilities require a margin of generating apaity above te firm demands of teir ustomers in order to provide reliable servie. Periodi seduled outages are required to perform maintenane and inspetions of generating plant equipment and to refuel nulear plants. At any given time during te year, some apaity may be out of servie due to unantiipated equipment failures resulting in fored outages of generation units. Adequate reserve apaity must be available to aommodate tese outages and to ompensate for iger tan projeted peak demand due to foreast unertainty and abnormal weater. In addition, some apaity must be available for operating reserves to maintain te balane between supply and dernand on a moment-to-moment basis.," _-,I PEF plans its resoures in a manner onsistent wit utility industry planning praties, and employs bot deterministi and probabilisti reliability riteria in te resoure planning proess. A Reserve Margin riterion is used as a deterministi measure of PEF's ability to meet its foreasted seasonal peak load wit firm apaity. PEF plans its resoures to satisfl a twenty (2) perent Reserve Margin riterion. 1- Loss of Load Probability (LOLP) is a probabilisti riterion tat measures te probability tat a ompany will be unable to meet its load trougout te year. Wile Reserve Margin onsiders te peak load and amount of installed resoures, LOLP takes into aount generating unit sizes, apaity mix, maintenane seduling, unit availabilities, and apaity assistane available from 1- * Progress Energy Florida, In. 3-25

74 'C.- oter utilities. A standard probabilisti reliability tresold ommonly used in te eletri utility industry, and te riterion employed by PEF, is a maximum of one (1) day in ten (1) years loss of load probability..n _- PEF as based its resoure planning on te use of dual reliability riteria sine te early 199s, a pratie tat as been aepted by te FPSC. PEF's resoure portfolio is designed to satisfy te twenty (2) perent Reserve Margin requirement and probabilisti analyses are periodially onduted to ensure tat te one (1) day in ten (1) years L'OLP riterion is also satisfied. By using bot te Reserve Margin and LOLP planning riteria, PEF's resoure portfolio is designed to ave suffiient apaity available to meet ustomer peak demand, and to provide reliable generation servie under expeted load onditions..pef as found tat resoure additions are typially triggered to meet te twenty (2) perent Reserve Margin tresolds before LOLP beomes a fator. Supply-Side Sreening Potential supply-side resoures are sreened to determine tose tat are te most ost-effetive. Data used for te sreening analysis is ompiled fi-on1 various industry soures and PEF's experienes. Te wide range of resoure options is pre-sreened to set aside tose tat do not warrant a detailed ost-effetiveness analys,is. Typial sreening riteria are osts, fuel soure, tenology maturity, environmental parameters, and overalll resoure feasibility. I" ICI Eonomi evaluation of generation alternatives is performed using te optimization program. Tis optimization tool evaluates revenue requirements for speifi resoure plans generated from multiple ombinations of future resoure additions tat meet system reliability riteria and oter system onstraints. All resoure plans are ten ranked by system revenue requirements. Demand-Side Sreening Like supply-side resoures, data for large inumbers of potential demand-side resoures are also olleted. Tese resoures are pre-sreened to eliminate tose alternatives tat are still in resear and development, addressed by oter regulations (e.g. building ode), or not appliable to PEF's Progress Energy Florida, In. 3-26

Demand-side programs tat pass te RIM test are ten bundled togeter to reate demand-side portfolios. Tese portfolios ontain te appropriate DSM options and make te optimization solvable wit te model. #- /- Resoure Integration and te Integrated Optimal Plan Te ost-effetive generation alternatives and te demand-side portfolios developed in te sreening proess an ten be optimized togeter to formulate integrated optimal plans. Te optimization program onsiders all possible future ombinations of supply- and demand-side alternatives tat meet te ompany's reliability riteria in ea year of te ten-year study period and reports tose tat provide bot flexibility and low revenue requirements (rates) for PEF's ratepayers. #- - /- Developing te Base Expansion Plan Te integrated optimized plan tat provides te lowest revenue requirements may ten be furter tested using sensitivity analysis. Te eonomis of te plain may be evaluated under ig and low foreast senarios for fuel, load and finanial assumptions, or any oter sensitivities wi te planner deems relevant. From te sensitivity assessment, te plan tat is identified as aieving te best balane of flexibility and ost is ten rieviewed witiin te orporate framework to determine ow te plan potentially impats or is impated by many oter fators.

76 .-,A,e KEY CORPORATE FORECASTS Load Foreast Te assumptions and metodology used to develop te base ase load and energy foreast is desribed in Capter 2 of tis TYSP. Fuel Foreast Te base ase fuel prie foreast was developed using sort-term and long-term spot market prie projetions from industry-reognized soures. Coal pries are expeted to be relatively stable mont to mont; owever, oil and natural gas pries are expeted to be more volatile on a day-today and mont-to-mont basis. C In te sort term, te base ost for oal is based on te existing ontrats and spot market oal pries and transportation arrangements between PEF and its various suppliers. For te longer term, te pries are based on spot market foreasts refletive of expeted market onditions. Oil and natural gas pries are estimated based on urrent and expeted ontrats and spot purase arrangements as well as near-term and long-term market foreasts. Oil and natural gas ommodity pries are driven primarily by open market fores of supply and demand. Natural gas firm transportation ost is determined primarily by pipeline tariff rates; and tends to ange less frequently tan ommodity pries. #-,.- Finanial Foreast Te key finanial assumptions used in PEF's most reent planning studies were 45 perent debt and 55 perent equity apital struture, projeted debt ost of 7.3 perent, and an equity return of perent. Tese assumptions resulted in a weigted average ost of apital of 9.75 perent and an after-tax disount rate of 8.5 perent. _- d-.- TEN-YEAR SITE PLAN (TYSP) RESOURCE ADDITIONS In tis TYSP, PEF's supply-side resoures inlude te relpowering of te P.L. Bartow Plant wit F-Class ombined yle tenology wit an expeted in-servie date of June 29. Te planned units in tis TYSP inlude te installation of ombustion turbine tenology at te Suwannee River Plant as well as two (2) nulear units on a greenfield site in Levy County. Progress Energy Florida, In. 3-28

77 ..-, In 28, te FPSC approved PEF s petition for a Determination of Need for te two (2) nulear units in Levy County. Te Company seleted Levy Units 1 and 2 for projeted ommerial servie in 216 and 217, respetively, to meet its generation apaity needs in te period 216 to 219 and beyond after arefully evaluating planning options troug te Company s on-going Integrated Resoure Planning (IRP) proess outlined erein. Te nulear units were identified as te most ost-effetive option to meet te need, taking into aount te need to improve fuel diversity, redue Florida s dependene on fuel oil and natural gas, redue urrent and potential future air emission ompliane osts, and ontribute to te long-term stability of te eletri grid. Sine nulear units involve very long liensing and onstrution lead times, PEF plans to ontinue wit te design and development of te infrastruture and transmission requirements, negotiations for prourement and onstrution ontrats (and permitting and liensing to support te urrent planned in-servie dates. However anges in fators su as, te projeted load growt and te timeline to obtain all te neessary state aind federal permits, ould impat PEF s base expansion plan. Troug its ongoing planning proess, PEF will ontinue to evaluate te timetables for all projeted resoure additions and assess alternatives for te future onsidering, among oter tings, projeted load growt, fuel pries, urrent lead times in te onstrution marketplae, projet development timelines for new fuels, and tenologies, and environmental ompliane onsiderations. Te Company will ontinue to examine tle merits of new generation alternatives and adjust its resoure plans aordingly to ensure optimal seletion of resoure additions based on te best information available.

Te Biomass Energy Group and te Vision Power failities will utilize an energy rop, tie BG&E units will fire gas from wood produts and Horizon Energy will gasify mimiipal solid,waste. r-,*- PEF ontinues to seek out renewable suppliers tat an provide reliable apaity and energy at eonomi rates. In July 27, PEF issued a Request for Renewables (RFR) soliiting proposals for renewable energy projets. PEF s RFR ontinues to reeive interest and to date as logged over 88 responses. Disussions wit potential suppliers are ongoing. PEF will ontinue to submit renewable standard offer ontrats in ompliane wit FPSC rules. In r-,a >- PLAN CONSIDERATIONS Load Foreast In general, iger-tan-projeted load growt would sifl: te need for new apaity to an earlier year and lower-tan-projeted load growtl would delay te need for new resoures. PEF s TYSP inludes in te sort-term te Bartow Repowering Projet urrently under onstrution and additions of ombustion turbine and nulear units in te long-term. Te Company s resoure plan provides te flexibility to sift ertain resoures to earlier or later in-servie dates sould a signifiant ange in projeted ustomer demand1 begin to materialize. /- Fuel Foreast PEF s urrent TYSP inludes new natural gas fueled resoures in 29, 214, and 215. Te plan also inludes uprates to te Crystal River nulear unit No. 3 in 29 and 21 1, and new 1- Progress Energy Florida, In

79 nulear units in 216 and 217. Higer gas pries would improve te eonomis for non gasfueled resoures and lower gas pries would benefit gas-fueled resoures. Unertainty over future environmental regulation, partiularlly as it relates to arbon, as well as fuel seurity and reliability onsiderations, favors pursuit of te nulear option. r- - Finanial Foreast PEF s urrent TYSP inludes ombustion turbines in 214. and 215 wit nulear unit additions in 216 and 217. Lower ost of apital and esalation rates would favor options wit longer onstrution lead times and iger apital osts su as te nulear addition. However, PEF does not expet tese assumptions to go mu lower tan te urrent base ase foreast and nulear generation is not projeted to be feasible before 216. PEF will ontinue to assess te eonomis of future generation alternatives inluding onsideration of te: unertainties in planning assumptions. r- 4-,n TRANSMISSION PLANNING PEF s transmission planning assessment praties are developed to test te ability of te planned system to meet te reliability riteria as oullined in te FERC Form 715 filing, and to assure te system meets PEF, Florida Reliability Coordinating Counil, In. (FRCC), and NERC riteria. Tis involves te use of load flow and transient stability ]programs to model various ontingeny situations tat may our, and determining if te system response meets te reliability riteria. In general, tis involves running simulations for te loss of any single line, generator, or transformer. PEF normally runs tis analysis for system peak and off-peak load levels for possible ontingenies, and for bot summer and winter. Additional studies are performed to determine te system response to redible, but less probable riteria. Tese studies inlude te loss of multiple generators or lines, ombinations of ea, and some load loss is permissible under tese more severe disturbanes. Tese redible, but less probable senarios are also evaluated at various load levels, sine some of te morle severe situations our at average or minimum load onditions. In partiular, ritial fault learing times are typially te sortest (most severe) at minimum load onditions, wit just a few large base load units supplying te system needs. 1-. Progress Energy Florida, In /-

80 As noted in te PEF reliability riteria, some remedial ations are allowed to redue system loadings, in partiular, setionalizing is allowed to redue: loading on lower voltage lines for bulk system ontingenies, but te risk to load on te setionalized system must be reasonable (it would not be onsidered prudent to operade for long periods wit a setionalized system). In addition, te number of remedial ation steps and te overall omplexity of te seme are evaluated to determine overall aeptability. Presently, PEF uses te following referene douments to alulate Available Transfer Capability (ATC) for required transmission pat postings on te Florida Open Aess Same- Time Information System (OASIS): FRCC: FRCC ATC Calulation and Coordination Proedures, April 4, 26, wi an be found on te FRCC s website: ttps://www. f?.om/atc WG/Sarel%2Doumenlts/FRCC%2OATC%2OCoordinatio n%2proedures.pdf NERC: Transmission Transfer Capability, May 1, 1995, NERC: Available Transfer Capability - Definitions and Determination, July 3, PEF uses te FRCC Capaity Benefit Margin (CBM) metodology to assess its CBM needs. Tis metodology is summarized as follows: FRCC Transmission Providers make an assessmemt of te CBM needed on teir respetive systems by using eiter deterministi or ]probabilisti generation reliability analysis. Te appropriate amount of transmission interfae apability is ten reserved for CBM on a per interfae basis, taking into aount te amount of generation available on oter interonneted systems, te respletive load peaking diversities of tose systems, and Transmission Reliability Margin (TRM). Operating reserves may be inluded if appropriate in TRM and subsequently subtrated from te CBM if needed. Progress Energy Florida, In. 3-32

Te Company is planning te onstrution of two (2) new nulear units at tis plant site wit planned operation to begin in 216 and 217. Te Levy County site (see Figure 4.3) is alpproximately 3,1 ares and loated eigt (8) miles inland from te Gulf of Mexio and rougly ten (1) miles nort of te existing PEF Crystal River Energy Complex. Te site is about 2.5 miles from te Cross Florida Barge Canal, from wi te Levy units may draw teir makeup water to supply te on-site ooling.water system. Te Levy County Plant Units 1 and 2, togeter wit te neessary assoiated site failities, will oupy approximately ten (1) perent of te 3,1 are site and te remaining areage will be preserved as an exlusionary boundary around te developed plant site and a buffer preserve. PEF purased an additional 2,1 are trat ontiguous wit te soutern boundary of te Levy site tat seures aess to a water supply for te site from te Cross Florjda Barge Canal as well as transmission orridors from te plant site. Te property for many years ad been used for silviulture and was designated as Forestry/Rural Residential. Te surrounding area land use is predominantly vaant, ommerial forestry lands. Tis site was osen based on several onsiderations inluding availability of land and water resoures, aess to te eletri transmission, system, and environmental onsiderations. First, te Levy County site ad aess to an adequate water supply. Seond, te site is at a relatively ig elevation, wi provides additional protetion from winld damage and flooding. Tird, unlike a number of oter sites onsidered, te Levy site as more favorable geotenial qualities, wi are ritial to siting a nulear power plant. Fourt, te Levy site provides geograpial separation from oter eletrial generating failities. E:ven toug te Crystal River Energy Complex site as many favorable qualities, adding new nulear generating apaity to te Crystal River Energy Complex at tis time would result in a signifiant onentration of PEF s generating assets in one geograpial loation. Tis inreases te likeliood of a signifiant generation loss from a single event and a potential large sale impat on te PEF system. Te Progress Energy Florida, In. 4-7

90 Levy County loation also would assist in avoiding a potential loss from a single signifiant transmission system event tat migt result in a large-sale impat on te PEF system. PEF s assessment of te Levy County site addressed weter any treatened and endangered speies or areologial and ultural resoures would be adversely impated by te development of te site for nulear generation units and related failities. No signifiant issues were identified in PEF s evaluations of te property. Te proximity of te Levy County site to te PEF s existing Crystal River Unit 3 nulear plant provides opportunities for effiienies in sared support funtions. Te two (2) Levy units will be loated on a greenfield site were site and transmission infrastruture must be onstruted along wit te buildings neessary for te power units. Te site will inlude ooling towers, intake and disarge strutures, ontainmimt buildings, auxiliary buildings, turbine buildings, diesel generators, wareouses, related site work and infrastruture, inluding roads, transmission lines, and a transmission substation. Te Company submitted a Site Certifiation Appliation (SCA) to te Florida Department of Environmental Protetion (DEP) on June 2, 28 for te entire site, inluding plants and assoiated failities for te units. Site ertifiation earings were ompleted in Mar 29, and te Siting Board may at on te final ertifiation by te end of August 29. Nulear power is a lean soure of eletri power generation. Eletri power generation from nulear fuel produes no sulfur dioxide (SOZ), nitrogen oxide (NO,), green ouse gases (GHG), or oter emissions. Terefore, it will ave a positive effet on te surrounding air quality. Water disarged from nulear plants must meet federal Clean Water At requirements and state water-quality standards. Before operating, a nulear plant s liensing proess requires an environmental impat statement tat arelidly examines and resolves all potential impats to water quality from te operation of te plaint.
