Alliant Puts 80 Megawatts On-line in Brazil

LCG, Dec. 7, 2001--Iowa utility holding company Alliant Energy Corp. said yesterday that a 50-50 joint venture between a subsidiary and Brazil's Companhia Forca e Luz Cataguazes-Leopoldina (Cataguazes) had begun operations at an 80 megawatt, gas-fueled power plant in southeastern Brazil.

Alliant Energy International and Cataguazes began producing power late last month when they commissioned a 40 megawatt combustion turbine at the Juiz de Fora power plant, and a second turbine has now begun commercial operation. Both are operating in simple cycle.

Alliant said the addition of a heat recovery steam generator and a steam turbine will permit the plant to operate in combined cycle by early 2003, at which time its output will be 103 megawatts.

The opening of a gas-fired power plant comes at an opportune time for Brazil. A sustained drought has crippled the country's hydroelectric industry, which represents most of its generation capacity. As a result, the Brazilian government has done everything possible to get new thermal plants on line.

"The time line for this project and others like it in Brazil have been accelerated," said Felicia Bellows, Alliant's managing director for Latin America. "We needed to move swiftly to take advantage of situational opportunities and government incentives in Brazil, while still keeping a close eye on the country's rapidly changing energy environment."
