CARMEL, Ind. — NextEra Energy Transmission Midwest LLC has been selected as developer for the new Hartburg-Sabine Junction 500-kV project in East Texas, the Midcontinent Independent System Operator announced today.
The NextEra proposal includes an estimated $115 million power grid investment consisting of a new 23-mile 500-kV transmission line and four 230-kV lines, as well as a new substation. The project will connect and improve the transmission network across Orange, Newton and Jasper counties in East Texas. Studies indicate the project will alleviate longstanding energy congestion issues and import limitations, allowing lower-cost generation to serve customers in the area.
“MISO was impressed by the quality and depth of all proposals for this project – and we congratulate NextEra on their merit-based selection as the developer,” said Aubrey Johnson, executive director of System Planning and Competitive Transmission for MISO. “NextEra’s proposal reflects the best overall balance of cost and value in the development and completion of this important project for the region.”
NextEra moves forward as the developer following a competitive selection process that included 12 proposals from 10 developers to construct, own, operate and maintain the project. Hartburg-Sabine is MISO’s second project after the Duff-Coleman project to undergo competitive selection, a process established by Order 1000 of the Federal Energy Regulatory Commission.
According to its tariff, MISO evaluates proposals based on cost and design, project implementation, operations and maintenance, and transmission planning participation – all relevant factors in ensuring project success. MISO used the established criteria and competitive selection process to evaluate proposals, ultimately to select the developer.
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.
“With developer selection complete, MISO will work closely with NextEra, state regulators and other stakeholders to support successful, on-time completion of the project,” Johnson added.
The project is expected to be in service by mid-2023. The complete selection report for the project is available on MISO’s Competitive Transmission webpage.
