2 Sempra Energy Sempra Energy Develops, Owns and Operates Large-Scale Energy Projects Sempra Generation is Focused on Wind and Solar Energy Projects in the Southwest Sempra has Substantial Financial and Technical Resources to Support Project Development Founded: June 26, 1998 Headquarters: San Diego, CA Revenues: Approx $11 billion Net Income: $1.1 billion Assets: $26.4 billion Employees: 13,600 Generation: 2,630 MW Customers: 29 million 2

3 Power Generation Facilities Western Generation Fleet 2,630 MW of natural gas-fired generation 3

4 Sempra Energy: Responding to the Need for Renewable Energy Reducing greenhouse gas emissions is one of the great challenges of our time: Renewable energy projects will play a key role in confronting climate change We are encouraged by the drumbeat of support for renewable energy in Washington, D.C. California is the national leader in these efforts Photo Credit: NPS 4

9 El Dorado Energy Solar Construction Commencement: July 23, 2008 Completion Date: December 22, 2008 Designed Capacity: 10 MW AC / 12 MW DC System Voltages: 1000 VDC / 315 VAC / 4160 VAC Construction Schedule: ~70,000 man hours / ~ 110 peak workforce 9

10 El Dorado Energy Solar Near Sempra Generation s existing natural gas-fired power plant located in Boulder City, Nev. 10 megawatt facility consists of more than 167,000 thin-film solar panels At peak production generates enough electricity to power approximately 6,400 homes IMAGE AREA (may contain multiple images) 10

11 El Dorado Energy Solar Rapid six-month assembly line installation process Lowered costs and enhanced efficiency About half the price of a similar size rooftop solar installation IMAGE AREA (may contain multiple images) 11

13 Copper Mountain Solar I EDE EDE Solar CMS1 CMSI Solar PV 48 ~380 Acres 230 kv Interconnection ~500 feet 13

14 Copper Mountain Solar I Project Description: Sempra Generation is developing Copper Mountain Solar I, a proposed new 48 MW expansion of the solar facility near Boulder City Construction will commence upon CPUC approval of the expansion project s power contract PG&E has contracted for the output of the combined 58 MW installation, which would contain almost one million solar panels 14

15 Mesquite Solar Project Description: Sempra Generation is proposing the development of Mesquite Solar, a photovoltaic (PV) solar energy generation facility that, when fully developed, will produce up to 400 megawatts (MW) of clean solar power Schedule: Mesquite Solar is planned to be developed at the rate of 50 to 100 MW per year, with construction expected to begin in

16 Mesquite Solar Electric Interconnection: Mesquite Solar will connect to the 500 kv Hassayampa switchyard via the existing Mesquite Generating Station 230 kv switchyard. New facilities will include a 230 kv generation-tie power line and a set of 230/500 kv transformers Permitting: A Comprehensive Plan Amendment designating the project site for solar development was approved by Maricopa County in December A Special Use Permit application for the Mesquite Solar project was filed with Maricopa County in March 2009 and approval is anticipated in the fall of

17 Energía Sierra Juárez Wind The border region of Northern Baja California has a high quality wind resource More than 1,000 MW of potential development 75 miles east of San Diego Easy access to the U.S. transmission system 17

18 Energía Sierra Juárez Wind Construction is scheduled to commence in 2011 Will install 45 to 55 wind turbines in Phase I, which translates to about 100 to 125 MW Total height 125 m to 145 m (410 ft), from base to blade tip Will employ about construction workers, most expected to be from the local region 18

19 Environmental Benefits Energía Sierra Juárez has the potential to generate 1,000 MW with no greenhouse gas emissions The project s wind energy is anticipated to displace over 1 million tons of global warming pollutants per year, if the full 1,000 MW were developed and sold into California Will help meet California s renewable energy mandates 19

20 Navajo Wind Project Overview Location: Capacity: Cameron, Arizona 250 MW (Phase I) to 500 MW total COD: Targeted for 2012 (Phase I) Capacity Factor: PPA Offtaker: Land: Interconnect: Wind Data: 33% TBD 45,000 acre mountain site Navajo Nation Tribal Land (1% impacted) Two ICR s filed in 2007 at Moenkopi 500 KV Sub System, Impact Study in Process Identified by True Wind, 3Tier, and NAU as one of the best wind sites in Arizona On-site data collected since June 2005 Completed installation of five 60- meter met towers in July
