Pacific Gas & Electric has the most ambition. Its proposed plants include: -Tesla--$850 million for 560 MW; -Colusa--$673 million for 657 MW; -Gateway--$370 million for 530 MW; and -Humboldt--$239 million for 163 MW. Sempra sees little growth in utility-owned generation. It\u2019s mostly relying on new transmission for its investments. It projects about a $1 billion investment in new generation to 2012, according to financial reports. The new utility owned plants would be: -Miramar Energy Facility II--46.5 MW, costing $56.6 million. The utility received expedited treatment for approval of the plant by the California Public Utilities Commission Sept 10. -Solar PV initiative--between 70 and 80 MW at a cost of up to $250 million; -Orange Grove--built by Japan-based J-Power to provide 96-99 MW of peaking power near Fallbrook. It received a $125 million loan for the project. According to Sempra, ownership will revert to SDG&E after the 25-year power purchase agreement. Southern California Edison\u2019s proposal for an Oxnard power plant is currently on hold due to local opposition. Other power plants are being planned by Edison\u2019s unregulated subsidiary.
