San Diego Gas & Electric (SDG&E), a subsidiary of Sempra Energy (NYSE: SRE), announced plans for what will be the largest solar power installation in San Diego, with an initial target of developing 70 to 80 megawatts of solar electricity.
SDG&E said it will own about two-thirds of the solar power system, the remainder will be customer- or third-party owned. Combined, the installations could be enough to power more than 50,000 homes.
"We hope this innovative SDG&E program sparks a dynamic public-private partnership to dramatically increase the use of solar power here in San Diego, so that our children and their grandchildren can continue to enjoy the environmental benefits of clean energy," Michael R. Peevey, president of the California Public Utilities Commission, said.
SDG&E will employ technology featuring photovoltaic panels that track the sun’s path throughout the day. As compared with typical commercial rooftop photovoltaic systems, the tracking technology will enable the photovoltaic panels to produce 65% more power during system peak energy demand and 40% more energy throughout the year. The utility will work with a variety of suppliers and installers on these projects.
The utility filed an application with the California Public Utilities Commission today to review and approve the framework of the program. With Commission approval, up to $250 million will be invested in solar installations over the next five years, with the first installations operational as early as next year.
Earlier this month San Diego City Attorney Michael Aguirre said his office may file a suit against SDG&E for failing to make progress towards the states 20% renewable energy goal for the year 2010.
