SOLON completed construction of 1.15 MW of solar systems for the Tanque Verde Unified School District (TVUSD) in Arizona. Spread over four campuses – Tanque Verde Elementary School, Aqua Caliente Elementary School, Emily Gray Junior High School, and Tanque Verde High School – the solar systems are a combination of shade structures and rooftop systems. With over 4,000 solar modules, the systems will offset a daytime electricity requirements of each campus.
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.
A challenging year brings a change in the rankings.

(September 2012) Our annual financial ranking shows some remarkable shifts among the industry’s shareholder value leaders. Despite flat demand and low commodity prices, investor-owned utilities are investing heavily in capital assets. Investment discipline and operational excellence distinguish leaders on the path to financial performance.
Panda Energy awards turnkey $300 million turnkey contract to Siemens and Bechtel; Dominion starts up 585-MW CFB plant; Ocean Power Technologies and Lockheed Martin partner on wave power project; Infigen awards wind turbine service contract to Mitsubishi; ITC commissions 345-kV line in Oklahoma; ABB tests world’s biggest DC transformer; Xcel gets green light for Tres Amigas-area transmission upgrades; plus contracts and announcements from Elster, Sensus, Enertech, and others.
(July 2012) Thanks for your enlightening editorial about the problems of feed-in tariffs for photovoltaic installations and the distortions they are causing in cost responsibilities among electric utility customers. While these issues are an immediate and growing concern, an entirely different set of problems will emerge over the next decade as the share of renewables in total generation approaches the high levels being dictated by most regulatory authorities.
