The Midwest Independent Transmission System Operator has announced Big Rivers Electric Corp.'s intention to fully integrate into the Midwest ISO as a transmission-owning member in September 2010.

Big Rivers will integrate its 1262-mile transmission system into the Midwest ISO, allowing the electric generation and transmission cooperative to access one of the largest markets in the world for buying and selling power. Big Rivers will also participate in the Midwest ISO's ancillary services market, which will benefit regional grid reliability by providing flexibility in addressing unexpected loss of generation and transmission. The Midwest ISO's markets' independence allows the most cost-effective and reliable source of generation to be matched with power needs.

"Fully integrating Big Rivers into the Midwest ISO markets enhances reliability and provides additional benefits, including more efficient generation dispatch, lower cost provision of ancillary reserves and more economic congestion management. In addition, expanding our operations in Kentucky will enhance regional transmission planning," said Richard Doying, vice president of Market Operations. "Greater market efficiency, increased reliability and enhanced transmission planning produce benefits for Big Rivers and all of our other members," he added.

Big Rivers' final integration into the Midwest ISO system is subject to certain regulatory and creditor reviews and approvals. The electric generation and transmission cooperative will benefit from Midwest ISO's regional planning initiatives that aim to identify the most effective locations and means for generation and transmission improvements. In addition, the Midwest ISO's long-term transmission expansion planning is expected to provide savings and cost reduction of approximately $1 billion annually by 2013. The Midwest ISO's independence and stakeholder process ensures that transmission system improvement recommendations are made solely to support power reliability and a strong market.

The addition of Big Rivers Electric Corp. incorporates approximately 1756 MW of generating capacity into the Midwest ISO's footprint.
