3 CSI THERMAL PROGRAM ELIGIBILITY REQUIREMENTS 3

4 Customer Class Customer Class and Incentive Rate determined by Utility Rate Shdl Schedule Residential Rate = Single family residential Commercial Rate = Commercial/Multi family 4

5 Customer Eligibility Host Customer: The utility customer of record at the location where the SWH system will be located. Natural lgas Water Heating Customers of PG&E, SDG&E, SCG 5 Electric Water Heating Customers of PG&E, SDG&E, SCE *Propane Water Heating Customers are not eligible ibl for a CSI Thermal incentive

6 End Use Eligibility: Multi family/commercial Multi family/commercial applications, SWH applications must directly consume the solarheated potable water, asopposed to using the solar heated water as a medium to carry heat for some other end use. In multi family/commercial applications, DHW and commercial end uses are eligible. Combination Systems: Applicants must provide documentation proving DHW energy savings for combination systems. Incentives will only apply to the DHW portion of the load. 6

7 Technology Eligibility Solar Water Heater Types Open Loop (Direct) Closed Loop (Indirect) Active Passive Active Passive Direct Forced Circulation Thermosiphon Indirect Forced Circulation Thermosiphon Not eligible systems for incentives 3 Integral Storage Collector (ICS) 7

8 Eligible Equipment Solar collectors used in Multi Family residential or Commercial SWH systems must have SRCC OG 100 Collector Certification Components must be new and unused, except for the following components: De scaled ldcopper piping Collector racking (design stamped by Structural Engineer to ensure the existing racks are appropriate for expected wind loading) System installations must conform to manufacturer's specifications and all applicable codes and standards All systems must have freeze and stagnation protection 8 SRCC= SolarRating & Certification Corp ( rating.org)

9 Ineligible Systems (not eligible for incentives) 9 Pools, spas, space heating, space cooling Non OG 100 collectors (e.g. concentrating solar collectors) Systems that use propane as the back up water heater Direct Forced Circulation, Open Loop Thermosiphon systems, Closed Loop Recirculation Systems that t re circulate water in the collector loop Combination systems will only receive an incentive for domestic hot water (DHW) energy savings (must clearly isolate DHW energy savings) End uses that do not directly consume the solar heated water, but rather use the water as a medium to carry heat for some other end use A SWH system that replaces a SWH system which previously received an incentive through the CSI Thermal Program Portable systems or systems that are not permanently installed. A SWH system that received incentives from a utility Energy Efficiency program. (Note: The California Energy Commission s Cash for Appliances Program is not a utility Energy Efficiency Program. Applicants may receive a CSI Thermal incentive and a Cash for Appliances incentive.)

10 Site Definition For multi family/commercial projects, site is defined as: The Host Customer s s premises, consisting of all the real property and apparatus employed in a single enterprise on an integral parcel of land undivided, excepting in the case of industrial, agricultural, oil field, resort enterprises, and public or quasipublic institutions divided by a dedicated street, highway or other public thoroughfare or railway. Automobile parking lots constituting a part of and adjacent to a single enterprise may beseparated byanalleyfromthe alley remainderof the premisesserved. Separate business enterprises or homes on a single parcel of land undivided by a highway, public road, and thoroughfare or railroad would be considered for purposes of CSI Thermal Program as separate sites. Note: The total incentives for multiple systems on one multi family/commercial site cannot exceed the incentive cap per customer class ($500,00 for Natural Gas, $250,000 for Electric). 10

25 CSI THERMAL PROGRAM INCENTIVES & APPLICATION PROCESS 25

26 Commercial/Multi family 250kWth Lump Sum Payment One time payment Based on estimated therm of kwh savings provided by the OG 100 Calculator Paid after project is completed, approved, and inspected (if applicable) 26

27 Commercial/Multi family > 250kWth 70/30 True Up Payment Payment made in two parts: 1) Commercial/Multi familycalculatorestimatestherm calculator estimates therm or kwh savings. PA pays 70 percent of that incentive after Incentive Claim and Inspection (if applicable) are approved 2) System is then metered/monitored for 12 consecutive months. PA pays the true up incentive amount by subtracting the initial i i l70 percent incentive i payment from the final metered incentive amount. 27 *Program will pay no more than 110% of estimated incentive

28 70/30 True up Example Actual energy savings less than expected Estimated energy savings is 12,000 therms per year which equates to a $153,840 incentive ($12.82 x 12,000) PA pays 70 percent of this amount, or $107,688 ($153,840x.70), once the project is completed, approved, and inspected (if applicable) Customer s energy savings is then measured for twelve months and is found to be 10,500 therms Based on the actual metered energy delivered from the SWH system, the total incentive amount is $134,610 (10,500 therms x $12.82 per therm) PA then pays the true up incentive payment of $26,922 ($134,610 $107,688 upfront lump sum incentive) 28
