NIPSCO Submits Request for Proposals to Purchase Power
RFP targets power needs for evolving electric marketplace

MERRILLVILLE, Ind. -- Northern Indiana Public Service Company (NIPSCO) announced today it has issued a Request for Proposals (RFP) seeking bids on power supplies designed to meet new and existing standards for reliability proposed by the Midwest Independent Transmission System Operator (MISO) and the North American Electric Reliability Council (NERC), as well as anticipated customer power requirements. The RFP requests power purchase bids of 150 Megawatts (MW) to meet the highly varying electricity demands of NIPSCO customers, as well as bids for a 250 MW block of power to supplement existing generating capacity during the peak summer months

“Our ongoing review of the MISO and NERC requirements has helped NIPSCO better define its future power needs,” said NIPSCO President Mark Maassel. “Along with our own generation capacity, this RFP process will result in NIPSCO meeting these new standards and continuing to supply safe, reliable service to all our electric customers.”

The MISO serves as an Independent Transmission Organization responsible for the reliable and efficient operation of the electric transmission system serving much of the Midwest. NERC was formed in 1968 to promote the reliability of the electric transmission system serving North America.

Burns and McDonnell Engineering has been retained by NIPSCO to assist in the RFP process and to receive the formal proposals from power suppliers. Proposals should be submitted to Burns and McDonnell at NIPSCOrfp@burnsmcd.com.

NIPSCO anticipates that the selection of a power provider will be determined prior to the implementation of the new MISO market. Proposals from bidders are due by November 5, 2004.
