The one-day-in-10-years criterion might have lost its usefulness in today’s energy markets. The criterion is highly conservative when used in calculating reserve margins for reliability. Can the...
output under a 20-year PPA at a fixed cost that Constellation says is less than projected market rates. HG&E’s solar power system will include 18,400 SolarWorld photovoltaic ground-mounted panels at two locations. The system is scheduled for commercial operation in summer 2011.
Hartz Solar Hamilton , a wholly-owned subsidiary of Hartz Mountain Industries, selected RMT Inc. to design and construct its Hamilton solar project. The facility, nominally rated at 7.5 MW AC, is located in Hamilton Township, Mercer County, N.J. RMT says it will begin construction in June, with commissioning in November. RMT is responsible for engineering, procurement, and construction (EPC) of the foundations and racking systems, the PV modules, the DC and AC collector systems, the SCADA system, and testing and commissioning. The project will involve installation of more than 30,000 Suntech 280-Watt crystalline PV modules.
The California Public Utilities Commission (CPUC) approved Pacific Gas & Electric ’s 20-year contract to purchase 150 MW of solar power from Sempra Generation ’s Mesquite Solar 1 PV power facility in Arizona. Mesquite Solar 1 is the first phase of Sempra Generation’s planned 700-MW Mesquite Solar complex located 40 miles west of Phoenix. With approval of the contract secured, the company plans to begin construction in June.
San Diego Gas & Electric (SDG&E) and subsidiaries of Soitec Solar Development signed three contracts with a combined capacity of 30 MW of solar energy. The electricity will be generated at three solar power plant sites in San Diego County that will use Soitec CPV modules to be manufactured in a new factory being built in the San Diego area. The contracts require approval from the California Public Utilities Commission.
San Diego Gas & Electric (SDG&E) entered a 20-year contract for up to 156 MW of power supplied from the first phase of Sempra Generation’s Energía Sierra Juárez wind project in Baja California, Mexico. Both SDG&E and Sempra Generation are subsidiaries of Sempra Energy. SDG&E selected Energía Sierra Juárez as part of the utility’s 2009 competitive solicitation for renewable resources. The project was compared to other competitive bids, and the process was overseen by an independent evaluator, as required by the California Public Utilities Commission (CPUC). The contract is subject to approval by the CPUC and Federal Energy Regulatory Commission. Construction on Energía Sierra Juárez 1, about 70 miles east of San Diego and just south of the U.S.-Mexico border, is expected to begin in 2012.
Ocean Power Technologies (OPT) awarded four contracts to Oregon companies in connection with the manufacturing of its PB150 PowerBuoy wave energy generating device. The four companies receiving contracts are: American Bridge Manufacturing, Oregon Iron Works, Cascade General (a subsidiary of Vigor Industrial), and Sause Bros. Inc. After the initial PowerBuoy is deployed and tested off the coast of Reedsport, expected later this year, OPT plans to construct the first commercial-scale wave power station in the United States, consisting of up to nine additional PowerBuoys and grid connection infrastructure, subject to receipt of all necessary regulatory approvals and additional funding.
Areva Solar was awarded a major contract to install a 44-MW solar thermal augmentation
