10 FMPA 5 Ten-Year Site Pian Executive Summary Executive Summary The following information is provided in accordance with Florida Public Service Commission Rules 5-.7, , and 5-.7, which require certain electric utilities in the State of Florida to submit a Ten-Year Site Plan. The Ten-Year Site Plan is required to describe the estimated electric power generating needs and to identify the general location and type of any proposed near-term generation capacity additions. The Florida Municipal Power Agency (FMPA) is a project-oriented, joint-action agency. FMPA s direct responsibility for power supply planning can be separated into two parts. First, for the All-Requirements Project (ARP), where the Agency has committed to supplying all of the power requirements of 15 cities, the Agency is solely responsible for power supply planning. Second, for member systems that are not in the ARP, the Agency s role has been to evaluate joint action opportunities and make the findings available to the membership where each member can elect whether or not to participate. This report presents information on the existing Agency projects and planning information for the ARP. The ARP winter and summer capacity including owned generation and purchase power for the year 5 is 1,744 MW and 1,73 MW, respectively. In October, 3, Stanton Energy Center A began commercial operation, providing FMPA with 17 MW of capacity. This includes the capacity allocated to Kissimmee Utility Authority pursuant to the applicable Stanton Energy Center A joint-ownership and purchase power agreements. Table ES-I presents uture ARP generation construction plans. Worthy of note is FMPA s awareness of the potential benefits of increased fuel diversity among its generating portfolio, which has prompted FMPA to consider a solid-fuel capacity addition. ue to permitting and scheduling constraints, commercial operation of such a unit, if ultimately decided upon, would not be feasible until the summer of 1 I at the earliest. Nonetheless, consideration and further study of the potential benefits related to construction of a new solid-fueled unit are appropriate from FMPA s perspective. The capacity expansion plan outlined in this Ten-Year Site Plan is consistent with the determination of the least-cost capacity expansion plan presented in FMPA s Treasure Coast Energy Center Unit 1 (TCEC Unit 1) Need for Power Application. The TCEC Unit 1 Need for Power Application provides the results of a detailed, -year (5-4) capacity planning study which identified construction of a new 1x1 7FA combined cycle at a new site, TCEC Unit 1, with a summer 8 commercial operation date. The TCEC Unit 1 Need for Power Application considered a number of sensitivity analyses to quantify the effects of changes to key input assumptions, including high and low fuel April 5 ES-I lack & Veatch

13 FMPA 5 Ten-Year Site Plan escription of FMPA 1. escription of FMPA 1.1 FMPA FMPA is a joint action agency comprised of 9 municipal electric utilities. FMPA provides economies of scale in power generation and related services to support community-owned electric utilities. FMPA was created on February 4, 1978, by the signing of the Interlocal Agreement among its original members to provide a means by which its members could cooperatively gain mutual advantage and meet present and projected electric energy requirements. This agreement specified the purposes and authority of FMPA. FMPA was formed under the provisions of Article VII, Section 1 of the Florida Constitution, the Joint Power Act, Chapter 36 1, Part 11, Florida Statutes, and the Florida Interlocal Cooperation Act of 1949, Section 1 63.O 1, Florida Statutes. The Florida Constitution and the Joint Power Act provide the authority for municipal electric utilities to join together for the joint financing, construction, acquiring, managing, operating, utilizing, and owning of electric power plants. The Interlocal Cooperation Act authorizes municipal electric utilities to cooperate with each other on the basis of mutual advantage to provide services and facilities in a manner and in a form of governmental organization that will accord best with geographic, economic, population, and other factors influencing the needs and development of local communities. Each city commission, utility commission, or authority, which is a signatory to the Interlocal Agreement, has the right to appoint one member to FMPA s oard of irectors, the governing body of FMPA. The oard has the responsibility of developing and approving FMPA s budget, approving and financing projects, hiring a General Manager and Genera1 Counsel, and establishing bylaws that govern how FMPA operates and creating policies that implement such bylaws. At its mual meeting, the oard elects a Chairman, Vice Chairman, Secretary, Treasurer, and an Executive Committee. The Executive Committee consists of I3 representatives, which include nine elected by the oard, the current oard Chairman, Vice Chairman, Secretary, and Treasurer. The Executive Committee meets regularly to control FMPA s day-to-day operations and to approve expenditures and contracts. The Executive Committee is also responsible for monitoring budgeted expenditure levels and assuring that authorized work is completed in a timely manner. 1. I. I A//-Requirements Project FMPA developed the ARP to secure an adequate, economical, and reliable supply of electric capacity and energy to meet the needs of the ARP members. ARP members, April lack & Veatch

21 FMPA 5 Ten-Year Site Plan 1.. ARP Power Supply Resources escription of FMPA A summary of existing ARP resources, as well as changes to existing purchase power contracts, is shown in Table 1-6. In addition to these resources, the ARP is currently implementing one generation project planned for operation January 1, 6, referred to herein as Stock Island Combustion Turbine Unit 4. This project is currently ongoing in the areas of preliminary engineering, permitting, and combustion turbine procurement. The Stock Island Combustion Turbine Unit 4 will be a General Electric LM6 PC-SPRINT combustion turbine with variable inlet guide vanes (VIGVs) rated for approximately 4 MW net at summer conditions. The combustion turbine will be installed at the KEYS Stock Island site in Key West adjacent to Combustion Turbine Unit 3, and will burn low-sulfur fuel oil. FMPA is in the process of filing its Treasure Coast Energy Cent Unit 1 (TCEC Unit 1) Need for Power Application, which explains its determination that the addition of a 1x1 7FA combined cycle is the most cost-effective unit addition to satisfy forecast capacity requirements in the summer of 8. It has also been assumed, consistent with the TCEC Unit 1 Need for Power Application, that FMPA would participate with other municipal utilities in the development of an 8 MW coal-fired project in the state of Florida. The primary advantage of a publicly-owned coal-fired project would be to diversify resources, while supplying competitively priced power into the future. The group is actively assessing sites and performing preliminary environmental and transmission line studies related to the project. FMPA s current participation is assumed to be 5 MW, with an anticipated commercial operation date of June 1, 1 1. It should be noted that neither the capacity associated with TCEC Unit 1 nor FMPA s participation in the 8 MW coal project are included in Table 1-6. m rn April lack & Veatch

A number of the ARP members own small amounts of capacity in Progress Energy Florida s Crystal River Unit 3. Likewise, a number of ARP members participate in the St. Lucie Project providing them capacity and energy from St. Lucie Unit No.. Capacity from these two nuclear units is classified as excluded resources in the Am. As such, the ARP members pay their own costs associated with the nuclear units and receive the benefits of the capacity and energy from these units. The April tack & Veatch

The nuclear units are, however, considered in the capacity planning for the ARP. The second category of resources is owned generation. This category includes generation that is solely or jointly owned by the ARP as well as ARP member participation in the Stanton, Tri-City, and Stanton I1 projects. The third category of resources is member generation. Capacity included in this category is generation owned by the ARP members either solely or jointly. The ARP purchases this capacity from the ARP members and then commits and dispatches the generation to meet the total requirements of the ARP. The fourth category is capacity solely owned by FMPA for the ARP. This capacity consists of Stock Island Combustion Turbine Units and 3. The fifth category of resources is purchase power. This includes power purchased directly by the ARP as well as existing purchase power contracts of individual ARP members, which were entered into prior to the member joining the Am. 1.3 Capacity and Power Purchase Contracts The current system firm power supply purchase resources of ARP include purchases from Progress Energy Florida (PEF), Florida Power & Light (FPL), Orlando Utilities Commission (OUC), Lakeland Electric, Gainesville Regional Utilities (GRU), Calpine, and the Southern Company-Florida Stanton A capacity that is purchased power. The power purchase contracts are briefly summarized below: PEF: FMPA has a power contract with PEF for Partial Requirements (PR) Services.

Forecast of emand and Energy for the All-Requirements Power Supply Project 3.1 I nt rod u ct i on Under the ARP structure, FMPA agrees to meet all of its members power requirements. To secure sufficient capacity and energy, FMPA forecasts each ARP member s loads on an individual basis and integrates the results into an FMPA forecast of electrical power demand and energy consumption for the entire AW. The following discussion summarizes the load forecasting process and the results of the most recent forecast. 3. Load Forecast Process FMPA prepares its load and energy forecast by month and summarizes the forecast annually. The load and energy forecast includes projections of customers, demand, and energy sales by rate classification for each of the AFW members. The forecast process includes existing ARP member cities that FMPA is currently supplying and ARP members that FMPA will supply in the future. Forecasts are prepared on an individual city basis and then aggregated into projections of FMPA s demand and energy requirements. In addition to the base case load and energy forecast, FMPA has prepared high and low case forecasts for each of the ARP participants. Though the high and low case forecasts do not represent defined scenarios, they capture a confidence band around the base case forecast. This band provides sufficient variation about which to develop robust power supply plans. In addition to the base case, the high and low case load forecasts were considered in the TCEC Unit 1 Need for Power Application Load Forecast Overview FMPA retained R. W. eck, Inc. (eck) to prepare a forecast of peak load and net energy for the ARP. The load and energy requirement forecast is a critical input to many utility processes including, but not limited to, generation expansion planning, fuel and purchased power budgeting, transmission planning, financial planning and budgeting, and staffing. Consequently, a rigorous and detailed process that relies on recognized standards of practice, as well as a thorough review of results by various parties, is essential to FMPA operations and long-term planning. The load and energy forecast (Forecast) was prepared for a year period, (4 through 3) and was extrapolated to 4 to allow a year planning period from 5 April lack & Veatch

34 FMPA 5 Ten-Year Site Plan Forecast of emand and Energy for the All-Requirements Power Supply Project to 4. The Forecast has been prepared on a monthly basis using municipal utility data provided to FMPA by the ARP members and load data maintained by FMPA. Historical and projected economic and demographic data was provided by Economy.coms a nationally recognized provider of such data. eck also relied on ARP members and their staffs for information and expert judgment regarding local economic and demographic issues specific to each member. The results of the Forecast show that the calendar year net energy for load supplied from the ARP is expected to grow at an annual average growth rate of.5 percent from 5-13, and then. percent through 4. The actual 4 peak of 1,414 MW was slightly higher than the projected peak. However, the actual 4 peak fell in the range of the high and low cases. The high and low cases do not reflect different projections of future conditions with respect to the explanatory variables. Rather, the high and low cases represent a band of uncertainty within which, in the near term, the annual peak and net energy are likely to fall under a single set of assumptions about the future. 3.4 Load Forecast Methodology ecause perfect knowledge about the future energy consumption of each member is not possible, FMPA relies on a forecasting process that balances complex mathematical models with sound judgment and, to the extent available, local, expert knowledge. In order to predict energy requirements, utilities need a forecasting methodology that explains variations in energy requirements. In addition, understanding relationships, that affect energy consumption, allows utilities to perform what-i f analyses, thereby improving decisions. For this reason, electric utilities typically rely on econometric forecasting techniques. Econometric forecasting makes use of regression to establish historical relationships between energy consumption and various explanatory variables based on fundamental economic theory and experience. These historical relationships (models) are evaluated, and then selected on their statistical ability to explain variations in the dependent variable of concern. The ability of a model to explain variations is often referred to as goodness-of-fit. The models are assumed to continue explaining variation in the future as they have in the past. Using projections of explanatory variables, the selected models produce a forecast of dependent variables. April 5 3- lack & Veatch

35 b FMPA 5 Ten-Year Site Plan Forecast of emand and Energy for the All-Requirements Power Supply Project 3.5 Model Specification The following discussion summarizes the development of econometric models used to forecast load, energy sales, and customer accounts on a monthly basis. This overview will present a common basis upon which each classification of models was prepared. For the residential class, the analysis of electric sales was separated into residential usage per customer and the number of customers, the product of which is total residential sales. This process is common for homogenous customer groups. For other rate classifications, the total sales series is the primary forecasted variable, and the customer forecast is generated for reporting purposes and to check the sensibility of the sales forecast. Residential class models typically reflect that energy sales are dependent on, or driven by: (i) the number of residential customers, (ii) real personal income per household, (iii) real electricity prices, and (iv) the weather. The number of residential customers was projected on the basis of the estimated historical relationship between the number of residential customers of the ARP members and the number of households in each ARP member s county. For the general service class models, the econometric models reflect that energy requirements are best explained by: (i) real retail sales, total personal income, or gross domestic product (GP) as a measure of economic activity and population in and around the member s service territory, (ii) the real price of electricity, and (iii) the weather. In the case of the general service nondemand class, retail sales were typically selected as the long-term driving variable either because it performed better by certain measures, or because the resulting forecast was more sensible. Similarly, for the general service demand class, total personal income was typically selected. For the industrial class, GP was the typical long-tern driving variable, except in cases where the forecast was based on an assumption (e-g., Clewiston and Key West). The weather model includes heating and cooling degree-days for the current month and for the prior month. Lagged degree-day variables are included to account for the typical billing cycle offset from calendar data. In other words, sales that are billed in any particular month are typically made up of electricity that was used during some portion of the current month and of the prior month. The eck 4 Load Forecast Report also provides an explanation of memberspecific modifications of the general theoretical model designed to account for dynamic behavior that occurred during the study period or is expected to occur in the future and for changes in the dependent variable that could not be adequately explained by the available April lack & Veatch

36 FMPA 5 Ten-Year Site Ptan Forecast of emand and Energy for the All-Requirements Power Supply Project data. The latter includes adjustments to account for observations of the dependent variable that are believed to be anomalous. While these adjustments artificially increase the fit of regression equations and are typically discouraged, large deviations from expected behavior tend to have a significant impact on the resulting forecast parameters. 3.6 Principal Considerations and Assumptions Historical Member ata FMPA staff provided historical data for each member. In addition, FMPA staff provided work papers and documentation for the 3 Load and Energy Forecast, which were prepared by FMPA staff. ata provided by FMPA staff included historical customers and sales by rate classification for each of the members. Revenue data was also provided; however, for part of the Study Period, only total revenues were available. ata was provided from January 199 or the year a new member joined ARP through at least June 3 and, in many cases, the end of fiscal year 3 (Le., September 3) Weather ata Historical weather data was obtained from the National Climatic ata Center (a division of the National Oceanic and Atmospheric Administration), which was generally used to supplement an existing weather database maintained by FMPA. Weather stations, from which historical weather was provided, were selected by their quality first, and second by their proximity to the member. In most cases, the closest first-order weather station was the best source of weather data. First-order weather stations (usually airports) generally provide the highest quality and most reliable weather data. However, based on statistical measures, there were two cases (Jacksonville each and Vero each) that weather from cooperative weather stations, which were closer than the first-order station to the members, appeared to be more reflective of select member conditions than the closest first-order weather station. The weather s influence on electricity sales has been represented through the use of two data series: heating and cooling degree-days (H and C, respectively). egree-days are derived by comparing the average daily temperature and (in the case of this forecast) 65 F. To the extent that the average daily temperature exceeds 65 F, the difference is the number of C required to cool the average daily temperature to 65 F. Conversely, H is the result of average daily temperatures, which are below 65 F. April lack & Veatch

37 FMPA 5 Ten-Year Site Plan Forecast of emand and Energy for the All-Requirements Power Supply Project ecause predicting future long-term weather patterns is impossible, normal weather conditions have been assumed in the projected period. Thirty-year normal monthly H and C are based on average weather conditions over the period Economic ata Economy.com, a nationally recognized organization, provided both historical and projected economic and demographic data. The data included economic and demographic data for each of the 15 counties in which members service territory resides. This data includes county population, households, employment, personal income, retail sales, and gross domestic product. Although all the data was not necessarily used in each of the forecast equations, each was examined for its potential to explain changes in the members historical electric sales. 3.7 Overview of Results ase Load Forecast The results of the Forecast show that, for each calendar year, AM s net energy for load is expected to grow at an annual average growth rate of.5 percent from 5 through 14, and then grow at an annual average rate of. percent through 4. Forecasts for the year 4 were developed by applying the growth rate from to 3 to the 3 forecasts High and Low Load Forecast The base case projection consists of an estimate of the future values for each of the dependent variables, the electricity sales by rate classification for each of the members, and all of the derived load determinants, including net energy for load and peak demand. The base case projection represents the most likely estimate of the dependent variables, given a particular projection of the independent variables. However, there is some uncertainty in those projections related solely to the uncertainty of the estimated parameters in the regression equations. This uncertainty is referred to as the standard error of the regression. Given this uncertainty, high and low projections were developed by adding and subtracting one standard error of the regression to the base case monthly projections. The high and low projections combine to form a band of uncertainty that is intended to capture approximately 67 percent of occurrences. April lack 8 Veatch

38 rn FMPA 5 Ten-Year Site Plan 3.8 Conclusions and Recommendations Forecast of emand and Energy for the All-Requirements Power Supply Project The results of this forecast have been influenced by several factors including data integrity, economic projections, and local knowledge. Each of these factors brings elements of bias and error, only some of which is controllable. To the extent that bias and error are removed from the forecast, the ability of the forecast to predict future load and energy requirements improves. The econometric methods used in this body of work thrive on large amounts of data. The larger the amount of data, the more likely it is that useful, stable relationships can be drawn from the data. In addition to the amount of data, the more closely the data represent what actually happened historically (and what will happen in the fbture), the better the models will be at predicting future load and energy requirements. In this forecast, eck reiied on economic projections provided by Econorny.com. Though Economy.com is a recognized provider used by many Florida utilities, they seem unlikely to inject significant local knowledge into their economic projections. To the extent that county-level economics are not representative of ARP member economics, the forecasting models may be biased. In addition, due to the lag of economic data reporting, the last two years or more of historical economic data are actually projections. To the extent that the projections of historical economics differ from actual economics, the forecasting models will be affected. As a general rule, local knowledge can play a significant role in developing reliable forecasting models. Local knowledge adds both a deeper understanding of historical data behavior and relationships and a useful expectation regarding how both are likely to change in the future. However, adjustments to forecasting models or underlying data should be made with considerable care. Overall, it is important to remember that the load forecast is an annual process. As projections become historical values, uncertainties in the current near term will diminish and be replaced with other uncertainties. However, barring significant and lasting changes to the underlying relationships, the econometric load forecast is a prudent and reliable means of forecasting load and energy. Tables 3-1 through 3-6 present the base case load forecast. Tables 3-7 through 3-9 present the high load forecast, and Tables 3-1 through 3-1 present the low load forecast. Table 3-13 presents the base case monthly load forecast. April lack & Veatch

57 FMPA 5 Ten-Year Site Plan Forecast of Facilities Requirements 5. Forecast of Facilities Requirements For member cities not involved in the All-Requirements Project, the responsibility for planning their fbture generation and transmission requirements lies ultimately with the individual utility. For the FMPA St. Lucie, Stanton, Stanton 11, and Tri-City Projects, FMPA has no power supply planning responsibility. However, FMPA periodically reviews the supply opportunities that might be worthwhile for FMPA or the cities to consider. FMPA s planning process involves evaluating new generating capacity, along with new purchased power options, if appropriate, and conservation measures that are planned and implemented by the All-Requirements Project participants. The planning process has also included periodic requests for proposals in an effort to consider all possible options. FMPA normally performs its generation expansion planning on a least- cost basis considering both purchased-power options, as well as options on construction of generating capacity and demand-side resources when cost effective. The generation expansion plan optimizes the planned mix of possible supply-side resources by simulating their dispatch for each year of the study period while considering variables including fixed and variable resource costs, fuel costs, planned maintenance outages, terms of purchase contracts, minimum reserve requirements, and options for future resources. FMPA currently plans for an annual reserve level of approximately 18 percent of the summer peak. Currently, the Agency, on behalf of the All-Requirements Project, is planning to add combustion turbine capacity at Stock Island in 6, additional combustion turbine capacity anticipated to be located at the Lake Worth site in 7, a 31 MW combined cycle unit (pursuant to the FMPA s Treasure Coast Energy Center Unit 1 Need for Power Application) in 8, 5 MW of coal-fired capacity in 1 1 (refer to Section 1. for discussion of this capacity addition), and will require a capacity addition in 14, likely to be a combustion turbine. FMPA s most recent capacity addition is represented by its share of Stanton Energy Center Unit A (Stanton A), a 633 MW gas-fired combined cycle unit which began commercial operation on October 1, 3. Stanton A is jointly owned by FMPA, KUA, OUC, and Southern-Florida. Combined, FMPA and KUA own seven percent of Stanton A, and purchase an additional 13 percent of the unit s capacity under a ten-year power purchase agreement with various provisions for capacity reductions as well as contract extensions. The addition of Treasure Coast Energy Center Unit 1 (TCEC Unit 1) was identified as the least-cost capacity addition to meet FMPA s forecast capacity April 5 5-f lack & Veatch

58 FMPA 5 Ten-Year Site Plan Forecast of Facilities Requirements requirements in the summer of 8 in FMPA s TCEC Unit 1 Need for Power Application. It has also been assumed that, consistent with the TCEC Unit 1 Need for Power Application, FMPA would participate with other public utilities in the development of an 8 MW coal-fired project in the state of Florida. The primary advantage of a publicly-owned coal-fired project would be to diversify resources, while supplying competitively priced power into the future. The group is actively assessing sites and performing preliminary environmental and transmission line studies related to the project. FMPA s current participation is assumed to be 5 MW, with an anticipated commercial operation date of June 1,1 1. Additionally, generation can be added at the Cane Island Power Park, at Lake Worth Utilities, at Vero each s Power Plant, and at Keys Energy Services Stock Island Plant. Further, reciprocating engines or small combustion turbine generation can be installed on all fifteen ARP member systems. FMPA is continually reviewing its options, seeking joint participation when feasible, and may change the megawatts required, the year of installment, the type of generation, and/or the site at which generation is planned to be added as conditions change.
