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 180-kW unit, at the Cobscook Bay site, including the on-shore station on Seward Neck, in Lubec, Maine. Two additional systems are expected to be installed in the fall of 2013. ORP’s Maine projects will sell power to Central Maine Power, Bangor Hydro, and Maine Public Service under 20-year agreements.
First Solar signed power purchase agreements with Pacific Gas & Electric for 72 MW (AC) of output from PV plants that First Solar is developing in central California. The 32-MW Lost Hills project is located in Kern County, and the 40-MW Cuyama project is in Santa Barbara County. Development plans contemplate starting construction in 2013.
Southern Company and Turner Renewable Energy acquired the 30-MW Spectrum solar photovoltaic (PV) project in Clark County, Nev., from SunEdison, which is building the facility and will operate it on a 311-acre site. The Spectrum project is the third to be acquired by the Southern-Turner partnership, and its first using solar tracking technology. Construction began in October with startup expected in the second quarter of 2013. NV Energy will buy the plant output under a 25-year agreement.
PSEG Solar Source completed the $50 million acquisition of a 15 MW DC (12 MW AC) solar project on an 80-acre site in Milford, Del., from Juwi Solar Inc. (JSI). Under separate agreements, JSI will engineer, procure, and oversee construction of the facility as well as perform operation and maintenance services for the project. Construction began in September, with completion scheduled for late 2012. The project will be owned by PSEG Solar Source, selling energy and renewable credits to Delaware Municipal Electric Corp. under a long-term agreement.
Arista Power completed the first phase of a project to develop an intelligent micro-grid for the U.S. Army. The project is part of the Renewable Energy for Distributed Under-Supplied Command Environments (REDUCE) program, under guidance from the U.S. Army Communications-Electronics Research, Development and Engineering Center (CERDEC). The micro-grid is being designed to automatically integrate renewable and traditional energy sources to deliver reliable power in areas where military operations are taking place. Program goals include minimizing the use of fossil fuels.
Echelon partnered with eMeter to integrate the energyIP platform with Echelon’s control operating system software. The integration is intended to provide utilities with operational and business insight into complex relationships among smart grid endpoints, networks, applications, and users.
The Midwest Independent Transmission System Operator (MISO) and its transmission owners reached two major milestones in its progress toward the U.S. Department of Energy’s (DOE) goal of revitalizing the nation’s electric grid through smart grid technology. As part of its synchrophasor technology deployment—which aims to improve MISO’s ability to perform grid diagnostics, system modeling, and after-the fact event analysis—MISO installed 161 phasor measurement units (PMU) on its 50,000-mile interconnected system across 11 states. Also MISO implemented a dynamic model enhancement process using results from the installed PMUs. This process is expected to allow MISO to more accurately determine transfer limits on the system. MISO expects to make available synchrophasor data to its real-time system operators in April 2013.
