CARMEL, Ind. — The MISO board of directors today approved a $130 million transmission investment to relieve system congestion in East Texas. The Hartburg-Sabine Junction 500-kV project qualifies as a Market Efficiency Project and is eligible for MISO’s competitive selection process.

 “Today’s board action ensures that the much-needed Hartburg-Sabine Junction project will move forward through a fair, transparent competitive-selection process,” said Kent Fonvielle, executive director for MISO’s South region, which encompasses the Texas project. “When completed, this project will help bring economic benefits to a transmission-constrained area of Texas.”

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.

Market Efficiency Projects provide economic benefits greater than project costs through increased market efficiency.

“Studies show the project will deliver a positive benefit-cost ratio,” noted Jennifer Curran, MISO vice president for System Planning and Seams Coordination. “The investment will strengthen the grid, alleviate longstanding congestion issues and import limitations, allowing lower-cost generation to serve customers in the area.”

MISO will issue a request for proposals on Feb. 6. Qualified developers will have until July 20 at 5 p.m. ET to submit proposals. MISO is required to announce a selected developer for this project by the end of 2018.

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, which was included as part of MISO’s Transmission Expansion Planning process, is expected to be in service in 2023.
