Eleven respondents have submitted proposals for MISO’s Duff-Coleman transmission project, the RTO’s first competitive project under FERC Order 1000.

MISO said Friday that all 11 proposals were judged complete.

“Now that we have finalized our review of the proposals for purposes of completeness, we will begin evaluating the proposals based on the criteria set forth in the MISO Tariff and our Business Practices Manual,” said Priti Patel, MISO North regional executive and executive director of the RTO’s competitive transmission administration.
