PG&E Background

4 PG&E and Our Business What we do: Deliver safe, reliable, and environmentally responsible gas and electricity to approximately 15 million Californians Electric and gas distribution customers 5.1 MM electric 4.2 MM gas Electric transmission circuits18,610 miles Gas transmission backbone6,136 miles Electric generation capacity6,000 MW

5 PG&E as a Partner and Solutions Provider PG&E Portfolio Solution Reduce Energy Use Renewable Power Supply ClimateSmart Partnership Education Outreach

6 Integration of EE and PV EE is typically much more cost-effective than PV California’s loading order requires that EE be implemented prior to PV Decreasing a facility’s consumption with EE reduces the size – and cost – of the PV system necessary to offset the facility’s load EE should be implemented prior to PV Why? Inquire about EE before installing PV

7 We’re Committed to Energy Efficiency 0 2,000 4,000 6,000 8,000 10,000 12,000 14, California United States Over the past 30 years, California per capita energy use has remained relatively flat compared to the 50% increase in U.S. per capita energy use. Source: California Energy Commission

13 SGIP Guidelines & Eligibility (Cont.) Maximum incentive is 3 MW, with maximum system size 5 MW 1 Must be interconnected and serve on-site load Non-Renewable systems must satisfy PU Code requirements or documenting a minimum electric efficiency equal to or greater than 40% of higher heating value basis All fossil fuel combustion generators must satisfy both a 60% overall system efficiency and a NOx emissions equal or less than.07 lbs/MWh 1 Per Decision (D.) , SGIP Administrators for 2008 and 2009, on a pilot basis, will pay qualifying distributed generation projects incentives up to 3 megawatts (MW) from prior years’ carryover funds

2009 SGIP Program & Updates

Program Updates California Supplier - An additional incentive of 20 percent will be provided for the installation of eligible distributed generation technologies from a California Supplier. (Section 3.5) AES - Advanced Energy Storage systems that meet certain technical parameters and are coupled with eligible SGIP technologies, currently wind and fuel cell technologies, are eligible in PY2009 and will receive an incentive of $2 per watt of installed capacity. The PY2009 budgets by SGIP Program Administrator are –

SGIP Incentive Rates For projects that are greater than 1 MW up to 3 MW, the incentives identified above declines according to the schedule below: CapacityIncentive Rate (Pct. of Base) 0 – 1 MW100% >1 MW – 2 MW50% >2 MW – 3 MW25%

PG&E Program Goals Encourage and facilitate more DG systems Reduce Barriers –SGIP Application Requirements –Interconnection Paperwork Expand Marketing & Outreach Efforts Possible partnerships with Developers and State Educate Community about DG systems and SGIP Program –Webinars, Classes, Expos, Conventions

Wind, Fuel Cells, and Advanced Energy Storage

19 Wind Requirements Wind turbine rated capacity is the highest electrical output from the manufacturer’s power output curve for wind speeds up to 30 mph including inverter losses. (Section 2.5.4) Wind Turbine Projects may be sized up to 200% of the Host Customer’s previous 12-month annual peak demand at the proposed Site. (Section ) Equipment: Inverter must be on CEC Approved List, Wind Turbines must be commercially available System Size: > 30 kW, < 30 kW applies through CEC Emerging Renewable Program 5-year system warranty

20 Fuel Cell Requirements Renewable Fuel Cell vs. Non-Renewable Fuel Cell –Renewable Fuel: Biogas, Landfill Gas, Digester Gas –Non-renewable Fuel: Natural Gas, Waste Gas –To qualify as a renewable fuel cell, fuel source must be > 75% renewable Non-Renewable Fuel cells must meet a minimum 40% operating efficiency requirement Fuel Cell Projects may be sized up to 100% of the Host Customer’s previous 12-month annual peak demand at the proposed Site. Equipment: Fuel Cell Equipment must be commercially available System Size: Capped at 5 MW with incentives up to 3 MW 5-year system warranty

21 Fuel Cells – Typical Applications Fuel cells with thermal byproduct (“CHP”) Electric-only fuel cells Ideal site characteristicsLarge thermal load to take advantage of “free” thermal product Coincident thermal and electrical loads to (ensures thermal product can be utilized) Any facility interested in self- generation Low thermal needs (otherwise CHP system may be potentially more attractive) Typical applications Colleges and universities Food/beverage processing Hospitals and prisons Hospitality Manufacturing Wastewater treatment Any facility interested in self- generation Thermal load not necessary for project economics Typical payback period ~ 8 to 15 years, with incentives (varies)

22 AES Background Timeline December VRB submitted a request to include AES as an eligible technology in the SGIP July 2007 – SGIP Working Group delivered split recommendation to CPUC for deliberation Summer 2008 – CPUC conducted additional fact finding through the proceeding. November 2008 – CPUC approved introduction of AES What is AES? AES stands for Advanced Energy Storage. These are battery-like storage systems that convert energy to a storage medium and then reconvert back to energy.

23 AES Requirements AES is to be coupled with a current SGIP technology. It is required that incentives be funded from the same budget as the accompanying technology. Any current or previously funded SGIP projects (Wind or Fuel Cells) is eligible to install AES and receive incentives. AES must be sized no larger than the rated capacity (kW) of the SGIP eligible technology it is operating in concert with. The Advanced Energy Storage Project capacity rating must be the net continuous discharge power output (kW) over a four hour period and must be established from manufacturer documentation.

24 AES Requirements (Cont.) Advanced Energy Storage systems utilizing hydrogen as the storage medium are not eligible at this time. (Section 2.5 and Section 6). Ability to meet IEEE Interconnection standards Ability to operate in distributed, customer sited locations and comply with all local environmental and air quality requirements 5-year system warranty consistent with other eligible program technologies
