projects in Huron, Calif., totaling 30 MW. The 20-MW and 10-MW projects were engineered and built for Pacific Gas and Electric (PG&E), and are the fourth and fifth in a series that Cupertino Electric designed and built for PG&E since 2011 under the utility’s clean energy initiative. Construction at the two sites began in late 2012 and finished in May 2013. 

China’s Sinohydro Resources contracted Toshiba Hydro Power to supply three 80-MW hydroelectric turbines and generators for the Nam Ou 5 hydro plant on the River Nam Ou in Laos. Toshiba will design and manufacture the turbines and generators and start delivery in January 2014. The first unit is expected to enter operation in December 2015. Following on from Nam Ngum 2 and Nam Ngiep 2, this is Toshiba’s third major order for a hydro plant in Laos. 

Washington Gas Energy Systems signed a contract with Rio Rancho Public Schools, Amsolar, and Conergy to build, own, and operate two 1,215-kW solar arrays at Cleveland and Rio Rancho High Schools in New Mexico. Washington Gas Energy Systems will own and operate the arrays under a 20-year agreement. The project was developed by Amsolar and will be built by Conergy, which is also supplying the equipment for both schools. Each solar installation will feature 2.9 miles of Conergy ground-mounted systems. When completed, the arrays are expected to produce 80 percent of the electricity required to power Cleveland and Rio Rancho High Schools. The project is under construction and expected to be completed this summer.

EDF Group selected the InStep Software Prism system for real-time asset monitoring of 58 nuclear units at 19 sites in France. The software will be used to identify and alert personnel of subtle changes in equipment behavior to provide early indication and diagnosis of asset health and performance problems. It also will help enable more targeted maintenance work to reduce operation and maintenance costs. EDF already uses Prism to centrally monitor its hydro and other fossil-fuel facilities. 

APR Energy announced a 200-MW expansion of its original 250-MW contract to supply mobile gas turbine generating systems in Libya. The systems will help cover anticipated power demand during the summer high heat season, as well as provide interim power while the country continues to rebuild and improve its infrastructure.

Duke Energy’s Edwardsport Generating Station, a 618-MW integrated coal gasification combined-cycle (IGCC) plant located in Knox County, Ind., began commercial operation after several months of delay and years of rising construction costs. Duke completed the necessary steps to declare Edwardsport commercial on June 7. This is the first time the IGCC technology has been used on this scale, so the plant is expected to build up to its long-term level of availability over the next 15 months. 

Siemens completed the Hemweg 9 and Diemen 34 combined-cycle power plants in the Netherlands for the Dutch utility Nuon, which is owned by Vattenfall. Siemens built the two 440-MW power plants under turnkey contracts. The company says the plants are capable of operating with an efficiency of almost 60 percent. As part of the turnkey contracts,
