CARMEL, Ind. — The Midcontinent Independent System Operator Inc. has completed an initial review of proposals submitted for the Hartburg-Sabine Junction 500-kV competitive transmission project. Nine developers submitted 12 complete proposals to construct, own, operate and maintain the project in East Texas.

“With the final list of complete proposals, we now begin our competitive evaluation phase, which is outlined in the MISO tariff,” explained Aubrey Johnson, MISO executive director for System Planning and Competitive Transmission.

The MISO board of directors approved the Market Efficiency Project in February as part of the regional transmission operator’s Transmission Expansion Plan for 2017. MISO issued a request for proposals on Feb. 6 and developers had until July 20 to complete submissions.

MISO expects to announce the selected proposal by Dec. 31, 2018.

The Hartburg-Sabine Junction project includes construction of a 500-kV line with a new substation in East Texas. The project also includes reconfiguring the existing Sabine- McFadden and Sabine-Nederland transmission lines into the new substation.

The Hartburg-Sabine Junction project is MISO’s second to undergo competitive selection, a process established by Order 1000 of the Federal Energy Regulatory Commission.

The project is expected to be in service in 2023. Visit MISO’s Competitive Transmission webpage to view the list of developers and project timeline.
