Climate impact, rates debated at coal plant hearing

 

Dec 5 - McClatchy-Tribune Regional News - Dave DeWitte The Gazette, Cedar Rapids, Iowa

The rate impact of Alliant Energy's planned coal-burning power plant in Marshalltown on consumers will soon be decided.

A hearing on the rate-setting principles for the Sutherland Unit 4 was winding down Thursday after four days of testimony and cross-examination of witnesses before the Iowa Utilities Board.

The plant is only the second new base-load coal plant proposed to the state in recent years. It has generated at least as much opposition as MidAmerican Energy's larger Walter Scott Jr. Energy Center Unit 4 plant, which began production last year.

The effect of the plant's air emissions on climate change was a primary issue for opponents at the initial state hearing that led to the approval of the plant with extensive conditions. The conditions include substantial investments by Alliant in additional wind energy generation, and the mandatory use of biomass to provide part of the plant's fuel.

At this week's hearing, plant opponents continued to oppose its construction, even though the main topic of the hearing was Alliant's request for a 12.55 percent rate of return on its investment.

Intervenors in the case, including Iowa's Office of Consumer Advocate, argued for a lower rate of return. They also have argued that the utility should bear most of the financial risk of complying with any future federal regulations on emissions of carbon dioxide.

"Iowans could pay 22 percent more for household electricity than they do now," said Tom Sanzillo, a former deputy controller for New York who testified for Plains Justice, a Mount Vernon-based legal advocacy non-profit focusing on environmental matters.

The group said the price increase would come on top of Alliant's previously announced plans to seek a separate 6 percent to 10 percent rate increase in early 2009.
