CPFL Energia announced the first unit began operation in February at the 880-mw Campos Novos project on the Canoas River in Brazil’s Santa Catarina State.
CPFL, which owns 48.72 percent of the project, said utility regulator Agencia Nacional de Energia Eletrica gave final approval to begin operation of the first 293.3-mw unit. It said the unit is responsible for 91 percent (average 342 mw) of the assured energy of the project.
Filling of the reservoir was completed January 31. Campos Novos’ completion schedule had been disrupted by a problem of leaking in the dam and diversion tunnel. The project resumed storing water in late November.
Work begins at 855-mw Foz do Chapeco
CPFL also announced construction is under way on the 855-mw Foz do Chapeco project on the Uruguai River at the border between Rio Grande do Sul and Santa Catarina states.
Environmental regulator Instituto Brasileiro de Meio Ambiente renewed the project license in December, clearing a schedule that anticipates the 2.1 billion real (US$970 million) project will go on line in 2011.
CPFL owns 51 percent of Foz do Chapeco. Other owners are Furnas Centrais Eletricas and Companhia Estadual de Energia Eletrica.

PROJECT DEVELOPMENT: Mexico restarts bidding to build 750-mw La Yesca
Mexico’s Comision Federal de Electricidad (CFE) restarted bidding for construction of the 750-mw La Yesca project on the Santiago River. Bids are due July 31.
To be located in Jalisco State, La Yesca is to include a 220-meter-tall concrete-faced rockfill dam, a reservoir of 2.39 billion cubic meters, and an underground powerhouse containing two 375-mw turbine-generators.
In late 2006, CFE rejected bids by consortia led by Mexico’s Ingenieros Civiles Asociados and by China’s Sinohydro Corp. because they exceeded the ceiling price. Another bid, by a group led by Italy’s Impregilo, failed to achieve technical requirements.
CFE said modifications in the bidding requirements were made to encourage greater participation by Mexican companies. CFE plans on first unit completion in February 2011, with project completion in June 2011.
