Midcontinent Independent System Operator (MISO) Says Presque Isle Coal-Fired Plant in Michigan Must Stay Open
The Midcontinent Independent System Operator (MISO) has concluded that the 431 MW Presque Isle coal-fired power plant must remain open for reliability reasons. As a result, it has denied the request by We Energies to suspend operations at its plant by February 2014. Discussions are underway between the company and MISO as to how to compensate the company for the mandated continued operation. Who will pay the cost will ultimately be proposed by MISO in a filing with the Federal Energy Regulatory Commission. The viability of the joint venture effort between We Energies and Wolverine Power Cooperative to upgrade the pollution control equipment at the plant is uncertain. In order for the facility to remain in compliance with the Federal Clean Air Act requirements on emissions, including mercury, upgrades in pollution control measures are required.
