Cupertino Electric is installing a new 230-kV transmission line to interconnect a new substation serving a 200-MW photovoltaic power plant in Imperial Valley, Calif. When complete in late 2013, the overhead line will span five miles and interconnect a new 230-kV substation on the 2,000-acre solar project site in California’s Imperial Valley.
SunWize Technologies is working with members of a North American consortium that includes Solexica Energy, JCM Capital, and Radical Energy, to develop two major PV projects in the Republic of Ecuador. The projects, known as Condor Solar and Solarconnection, comprise solar arrays totaling 30 MW (AC) and 20 MW (AC) of capacity respectively. The facilities will feature approximately 234,000 solar panels, multiple inverters, and a substation to distribute energy in northern Ecuador.
SOLON completed construction of a 459 kW photovoltaic (PV) system at the Reverse Osmosis Water Treatment Facility for the Town of Gila Bend, Arizona. The system is expected to offset the plant’s energy usage by 86 percent. The project was financed through a State of Arizona Water Infrastructure Finance Authority grant, awarded to the Town of Gila Bend for drinking water infrastructure improvements. SOLON says it has installed nearly 65 MW of solar in Arizona, and 90 MW nationwide.
M and B Switchgears Ltd. in Madhya Pradesh, India, awarded a contract to AEG Power Solutions to provide inverters for a 30-MW solar power project. Delivery is expected in the first quarter of 2013. M and B Switchgears Ltd., a major transformer manufacturer, signed an agreement with the government of Madhya Pradesh last October to develop nearly 100 MW of solar power plants throughout the state.
Sempra U.S. Gas & Power, BP Wind Energy and community leaders dedicated the new Auwahi wind facility on Ulupalakua Ranch in Hawaii. The 21-MW Auwahi Wind facility is BP and Sempra’s first alternative energy venture in Hawaii. The project features a 4.4-MWh grid battery system, which at its peak, can sustain 11 MW of capacity for approximately 25 minutes. The battery system helps regulate and sustain power to Maui Electric Co.’s grid during light wind conditions.
NRG Solar started commercial operations for the Alpine solar generating station, a 66-MW (AC) photovoltaic (PV) facility, which NRG says is the largest fully operational solar plant in California. The station’s output will be sold to Pacific Gas & Electric under a 20-year agreement.
Constellation completed an aggregate 5.7-MW (DC) solar generation project for Portland General Electric (PGE) in Lake County, Oregon. Constellation financed as well as owns and operates the solar power system. In return, PGE purchases and receives all of the electricity generated by the solar panels at a fixed rate from Constellation under a 25-year solar power purchase agreement (PPA). The solar power system comprises more than 20,000 ground-mounted photovoltaic panels.
Duke Energy Renewables, part of Duke Energy's Commercial Businesses, completed its 36-MW energy storage and power management system at its Notrees Windpower Project in west Texas. The system completed testing and became fully operational in December 2012. Xtreme Power designed and installed the 36-MW capacity Dynamic Power Resource at Notrees and will continue to operate the system. In addition to increasing the supply of renewable energy during periods of peak demand, the system will help stabilize the frequency of electricity traveling throughout the power grid.
Alstom signed a €250 million contract with Metals & Engineering Corp. (METEC) to supply turbines and generators for the hydro power plant of the Grand Renaissance dam, located on the Blue Nile in Ethiopia. Alstom will supply and supervise the installation of all electromechanical equipment for the plant, including eight 375 MW turbines and eight generators for the first phase. The contract also includes engineering and power plant commissioning, scheduled to start in late 2013 and finish in 2016.
Sempra U.S. Gas & Power completed construction of Mesquite Solar 1, the first 150-MW phase of the company’s Mesquite Solar complex in Arlington, Ariz., about 40 miles west of Phoenix. The photovoltaic (PV) solar energy project now is operational and ranks among the largest in the United States.
