MISO Duff-Coleman RFP Deadline Passes; RTO Reviewing Bids
MISO closed its request for proposals on the Duff-Coleman 345-kV transmission project in Southern Indiana on July 6, reviewing "robust" number of proposals.

MISO closed its request for proposals on the Duff-Coleman 345-kV transmission project in Southern Indiana on July 6, saying it was pleased with the response.

Priti Patel, MISO North regional executive, said MISO was satisfied with the “robust” number of proposals on its first competitively bid project, but she didn’t disclose the number of proposals received or which developers submitted them. Patel said the RTO will post the list of developers that submitted complete proposals by Aug. 19. In the meantime, proposals are under review to determine their eligibility. Forty-eight developers qualified to submit bids to MISO.

“The broad interest from transmission developers demonstrates confidence in MISO’s competitive processes,” Patel said in a statement.

Per its original timeline, MISO expects to announce its transmission developer pick on the $67.4 million project by Dec. 30. The RFP window opened in January for the work, which includes the construction of two substations and a 28.5-mile line linking them. (See MISO Seeks Bids on Duff-Coleman Project.)
