CARMEL, Ind. — The Midcontinent Independent System Operator has authorized a $3.3 billion transmission expansion plan for 2018, a portfolio of 442 projects to improve the reliability and efficiency of the mid-continent region’s power grid. The MISO board of directors gave its final approval to the plan earlier in December.
“The MTEP process reflects a thorough, continual analysis and planning effort to ensure the region is well-positioned to meet future electricity demand and regulatory requirements, all against the backdrop of a continually evolving electric industry,” said Aubrey Johnson, MISO executive director of System Planning and Competitive Transmission. “The process is enriched by robust stakeholder engagement that results in well-vetted, cost-effective and innovative solutions that enable reliably-delivered energy at the least cost to consumers.”
Projects in MTEP18 continue to support local reliability and market efficiency as MISO works with stakeholders to meet future system needs, including a resource fleet rapidly evolving toward more renewables. The 10 largest projects approved represent about 23 percent of the overall investment and are distributed across the MISO region. Those largest projects enable new load and generation interconnection and support NERC reliability compliance and local needs.
MTEP18 also includes two Targeted Market Efficiency interregional projects to address congestion at the PJM-MISO seam:
MTEP18 is the 15th edition of the annual report and represents collaborative system planning across a diverse geographic and regulatory landscape covering 900,000 square miles. Since 2003, more than $19 billion of project investments have been constructed in the MISO region.
