Iowa Utility Cuts Service as Power Supply Falters
May 15, 2001Alliant Energy Corp. declared a power conservation alert yesterday for its customers in Iowa and began curtailing service as the result of insufficient power supply and transmission constraints. The company was unsure of the root cause of the problem."What we're looking into is whether there is a problem with a power plant somewhere," said John Ruff, an Alliant spokesman. The company began shutting off power to customers, including schools, yesterday morning.Alliant is the company formed by a merger between Wisconsin Power & Light Co. and two Iowa utilities. The company was among supporters of legislation that would have streamlined the process of building new power plants in Iowa, but the measure died in the Iowa legislature when lawmakers adjourned for the year earlier this month.Ruff said Alliant had been notified of a transmission problem by the Mid-American Interconnected Network, or MAIN, which oversees reliability of electricity transmission in a region including all of Illinois and parts of Iowa, Wisconsin, Minnesota, Michigan and Missouri.MAIN said a number of Iowa power plants were shut down yesterday, which caused an increase in power imports from Illinios. That has caused some very heavy loading on transmission lines into Iowa in the Quad Cities area," said MAIN spokeswoman Jackie Olson.
