Port Washington Plant Repowering Begins

LCG, Mar. 24, 2003--The planned repowering of the Port Washington power plant was to have proceeded this past weekend with demolition of its southern stack, making way for two new 500-megawatt gas generators.

We Energies, the Wisconsin gas and electric utility, has been planning an upgrade of the plant, which began in 1935 as a coal-burning, 348-megawatt facility. "This will be the most visible sign to date that we are making progress in our plans to upgrade the Port Washington Power Plant. Our Power the Future plan will ensure reliable, affordable electricity for our customers and this is an important step," Scott Patulski, vice president for fossil operations, said.

The ownership of the plant was to be retained by We Power, a new subsidiary of Wisconsin Energy. According to its original application, We Energies would lease the plant, and have a right to up to 20% of the power. Other co-owners that were listed are Madison Gas and Electric Co. and Dairyland Power Cooperative. Revenue earned by the plant could be used to offset rates paid by the utility's customers, according to a December ruling by the Public Service Corporation. At that time, the PSC also agreed to allow a 12.7% return on equity in the plant.
