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...
a cost competitive solar technology that uses earth-abundant materials.
AllEarth Renewables , a Vermont manufacturer of grid-connected wind turbines and solar tracking systems, received a contract from Chittenden County Solar Partners to install 382 AllSun Trackers at a solar farm in South Burlington, Vt. The installation will be the largest solar array to date in the state of Vermont and is scheduled to begin operations by early 2011.
RMK Solar began building one of the largest ground-based solar energy systems in Pennsylvania, under contract with pretzel maker Snyder’s of Hanover . When completed the solar farm will include more than 15,000 panels spanning 26 acres, directly across from the Snyder’s of Hanover corporate headquarters and manufacturing facility in Hanover, Pa.
Pattern Energy Group says the 101.2 MW Hatchet Ridge wind project in Burney, Calif., is now operational and selling electricity to PG&E under a 15-year power purchase agreement. RES America Construction built the wind farm infrastructure, while Siemens erected 44 of its SWT-2.3-93 wind turbines, equipped with blades manufactured in Fort Madison, Iowa. Ameron International of Fontana, Calif., supplied turbine towers. Pattern Energy says the 101.2 MW wind energy project is the only large-scale wind project in California to reach operation this year.
Airstreams Renewables, Inc. (ARI) announced plans to build a 20,000 square-foot renewable energy training center on a 33-acre parcel that ARI owns in Tehachapi, Calif. The training center will be located adjacent to a 1.5 to 2 MW solar park that a solar developer plans to build on 14 acres of ARI’s land, under lease for 33 years. Project construction is scheduled to begin in 2013. Additionally, ARI plans to significantly expand its ENSA North America subsidiary across the U.S. and Canada and to deploy additional mobile training facilities, in addition to hiring and training technical trainers.
GE’s Jenbacher announced the development of a new power-generation gas engine, the J920 engine, with electrical efficiency of 48.7 percent and an output of 9.5 MW. GE says the new engine will emit 1,500 tons of CO2 per year less than a comparable engine.
The Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE), the Department of Energy (DOE), and the Department of Commerce’s National Oceanic and Atmospheric Administration (NOAA) announced eight joint research awards totaling nearly $5 million to support the responsible siting and permitting of offshore wind energy facilities and ocean energy generated from waves, tides, currents and thermal gradients. The following projects were selected for awards: 1) Parametrix, Auburn, Wash., $499,000 to apply probabilistic statistical methods to evaluate ocean renewable energy siting proposals; 2) Cornell Lab of Ornithology’s Bioacoustics Research Program, Ithaca, N.Y., $499,000 to study how offshore alternative energy (OAE) activities affect marine vertebrates; 3) University of Rhode Island, Kingston R.I., $745,000 to develop standardized data protocols for specific offshore renewable energy issues; 4) University of Washington-School of Aquatic and Fishery Scientists, Seattle, Wash., $746,000 to evaluate acoustic technologies for studying animal populations at a proposed hydrokinetic site; 5) Pacific Energy Ventures, Portland, Ore., $499,000 to build an environmental data protocol framework for evaluating offshore renewable energy projects;
