Largest concentrating solar power plant
Siemens Industry Inc., Atlanta, is shipping its Robicon Prefect Harmony medium-voltage drives to support a multimillion contract with Abengoa, an international developer of renewable-energy solutions in Spain. Abengoa is supplying the drives for Solana, a 280-MW (net) facility near Gila Bend, Ariz., which, upon completion, will be the world's largest concentrating solar-power plant. Abengoa has a 30-year contract with Arizona Public Service, Arizona's largest electric utility, to build and operate the plant.
Conenrgy, Hamburg, Germany, and TÜV Rheinland will be collaborating in the certification of large photovoltaic plants. The goal of the partnership is to evaluate and certify all of Conergy's large power plants neutrally to TÜV Rheinland's standards in the solar sector.
The G3-PLC protocol from Maxim Integrated Products Inc., Sunnyvale, Calif., has been recommended by the Smart House Standardization Study Group, sponsored by Japan's Ministry of Economy, Trade, and Industry, as one of the communications platforms that Japanese electrical utilities should use for communication between a smart meter and a home energy-management system (HEMS) in home-area networks (HANs).
In partnership with Electricité Réseau Distribution France and Sagemcom, Maxim developed the protocol to promote open-endedness and interoperability among smart-grid implementations.
Dow Solar is making its Powerhouse Solar Shingles available to homeowners in northern California and central Texas — specifically San Antonio and Austin — through authorized dealers, including Town & Country Roofing and Dority Roofing in northern California, and three professional roofing contractors that will serve central Texas: Beldon Roofing, Quality Roofing, and Ja-Mar Roofing.
