the third quarter of 2012. The project will consist of approximately 88,000 polycrystalline solar modules provided by Trina Solar. Nevada Power will buy the output under a 25-year agreement.

Algonquin Power paid $29.7 million to acquire an interest in the Sandy Ridge (Penn.) wind farm, the first of four projects comprising a 480-MW wind portfolio under construction by Gamesa Corporación Tecnológica, S.A. in the United States. Sandy Ridge, which achieved commercial operation in February 2012, is comprised of 25 Gamesa G9X-2.0 MW wind turbines and has a 10-year power sales contract with J.P. Morgan Ventures. Gamesa will provide operations, warranty, and maintenance services for the wind turbines and balance-of-plant facilities under a 20-year contract. Algonquin says it will fund the acquisition with approximately 40 percent debt and 60 percent equity.

Algonquin subsidiary Liberty Utilities completed its $285 million acquisition of National Grid’s natural gas and electric distribution businesses in New Hampshire. The final state and federal regulatory approvals needed to complete the transaction were granted this past May. The sale was originally announced in December 2010.

Consolidated Edison Development (CED) acquired two PV projects totaling 70 MW from GCL Solar Energy, a subsidiary of GCL-Poly Energy Holdings. The projects in California’s Central Valley are scheduled to begin commercial operation in the fourth quarter of 2012. CED will own and operate the projects and sell power and renewable energy certificates to Pacific Gas & Electric under 25-year power purchase agreements.

Smart Grid

Grid Net added new features to its software to support public cellular and other smart grid network communications systems. The Grid Net Platform v2.7—a centrally managed, distributed smart grid network operating system—now supports more point-to-point public and private broadband networks, including 4G WiMAX, 4G LTE, Ethernet over fiber, and 3G UMTS, and EVDO CDMA. The software features an application framework for machine-to-machine network optimization, content distribution optimization and control, off-peak network utilization, differential state synchronization, and configurable connectivity.

 

Survalent Technology commissioned a new SCADA system at Paulding Putnam Electric Cooperative (PPEC) in northwestern Ohio and Indiana. The SCADA system is equipped with several of Survalent’s applications.

Transmission

ITC Great Plains , in conjunction with Western Farmers Electric Cooperative (WFEC), commissioned its Hugo-Valliant high-voltage electric transmission line and substation project in southeastern Oklahoma. The 18-mile, 345-kV line and substation is expected to reduce system congestion, provide more efficient and cost-effective transmission of energy, and increase access to a broader range of generation resources. The substation, near WFEC’s Hugo power plant, provides a link to the WFEC 138-kV transmission system.

ABB successfully developed and tested a 1,100-kV ultra high-voltage direct current (UHVDC) converter transformer, which the company says broke the record for the highest DC voltage levels ever. The technology is intended to allow efficient transmission of larger amounts of power over longer distances—namely, more than 10,000 MW of power across distances as long as 3,000 km. These figures compare with ABB’s largest commercial UHVDC system, the 800-kV Xiangjiaba-Shanghai link, with a capacity of 6,400 MW and extending just over 2,000 km.
