Peabody Gains Momentum for Prairie State Energy Campus
LCG, September 5, 2007--Peabody Energy announced yesterday that Southern Illinois Power Cooperative (SIPC) has executed an agreement to purchase a 125 MW equity share of the Prairie State Energy Campus. Peabody plans to build the 1,600-MW, coal-fired power plant in Washington County, Illinois and is planned to provide base-load power to a number of public power entities in the region.
Prairie State's partner group includes: American Municipal Power-Ohio; Illinois Municipal Electric Agency; Indiana Municipal Power Agency; Kentucky Municipal Power Agency; Missouri Joint Municipal Electric Utility Commission; Northern Illinois Municipal Power Agency; and Prairie Power Inc.
The estimated cost of the Prairie State Energy Campus is $2.9 billion. The facility will include two, 800-MW, supercritical units that are scheduled to commence commercial operations in 2011 and 2012. The power plant will be located adjacent to the Lively Grove Coal Mine.
Late last month, a three-judge panel from the Seventh Circuit of the U.S. Court of Appeals unanimously affirmed the air permit for the Prairie State Energy Campus. The recent decision is the latest milestone in a six-year, regulatory review process that includes approval by the Illinois Environmental Protection Agency and the U.S. Environmental Protection Agency.
