MidAmerican’s Solar Star projects will supply SoCal Edison

JinkoSolar Holding (JinkoSolar) will supply 35 MW of solar PV modules to Clenera, a clean energy finance and management firm, for the construction of the Avalon Solar Project. According to terms of the agreement, groundbreaking is expected to begin during the second quarter of 2014, with an anticipated completion date during the fourth quarter of 2014. Swinerton Renewable Energy will provide EPC services for the project. The power will be sold to Tucson Electric Power .

Abengoa completed construction of Mount Signal Solar, the 206-MW photovoltaic plant in the city of Calexico, south east of California. Abengoa was responsible for the engineering, construction and commissioning of the plant for Silver Ridge Power. The project covers 801 hectares and includes more than three million photovoltaic modules that rotate on a north-south axis tracking the path of the sun.

MidAmerican Solar and SunPower installed the one millionth photovoltaic module at the Solar Star projects, co-located in Kern and Los Angeles counties in California. When complete, the 579-MW projects will have more than 1.7 million modules installed. The first solar module was installed in March 2013. The Solar Star projects are owned by MidAmerican Solar and are being constructed by SunPower, which also will provide operations and maintenance services. Construction on the projects began in 2013 and is expected to be complete by year-end 2015. Southern California Edison will purchase electricity from the projects under two long-term power purchase agreements.

SunPower will build utility-scale Oasis project in Colorado

Xcel Energy and SunPower signed a PPA to build a 50-MW solar power plant in Colorado's San Luis Valley. Construction of the solar power plant is contingent on the project securing all required permits, interconnection rights and financing. SunPower expects to start construction in 2015, and to achieve full commercial operation by the end of 2016. At the 320-acre site, SunPower will design and build a SunPower Oasis Power Plant system. Oasis is a fully integrated, modular solar power block that is engineered to rapidly and cost-effectively deploy utility-scale solar projects while optimizing land use.

ABB introduced a new grid feeding monitoring relay for wind applications. The new low-voltage grid feeding monitoring relay CM-UFD.M33, also known as the Grid Tie Relay, is a component that protects wind turbines from unstable grid activity or faults by disconnecting the electric energy source from the grid. The relay monitors voltage and frequency in single and three phase grids and trips the coupling switch when electrical values are not within set parameters. If a fault is detected, the grid feeding monitoring relay sounds an alarm, displays a message and then signals the alarm cause to the control system.

SunPower and AE-AMD Renewable Energy , a joint venture between the Spanish AMDA energía and the South African Alt-E Technologies, as well as its partners have completed two South African ground-mounted solar projects and are now feeding 33 MW into the grid. Both projects, which were constructed by SunPower, are located near Douglas, South Africa in the Northern Cape Province. Herbert, a 22-MW project, and the 11-MW Greefspan project, were both part of the South African government's Independent
