On July 25, the Midcontinent Independent System Operator (MISO) Board of Directors approved an ambitious long-term plan to expand transmission infrastructure in the MISO North and Central regions (now called MISO Midwest) to serve growing demands for renewable energy and improve system reliability. The Long-Term Regional Transmission Plan (LRTP) is the second such major long-term regional transmission plan approved by MISO in the past 12 years, building on the Multi-Value Projects (MVP) transmission plan approved by MISO in 2011. MISO’s long-range planning efforts in MISO Midwest can serve as a national model for how to conduct long-range transmission planning to meet the needs of a changing generation resource mix. Meanwhile, the fact that the MISO South region will not see a similar plan until 2024 at the earliest demonstrates the challenges that must be overcome to ensure such effective planning happens everywhere – and leads to development of the transmission needed for a clean energy future.

Transmission Buildout Requires State as Well as Federal Engagement

The need to deploy vast new supplies of advanced energy technologies to achieve a 100% clean electricity system and power the transportation and building sectors with clean electricity is well documented. Expanding the nation’s electric transmission infrastructure — the long-distance high-voltage lines that deliver electricity in bulk from generation resources to local distribution networks — is a key part of achieving that goal. A variety of challenges stand in the way of transmission expansion, ranging from weak planning processes, to fights over who will pay the cost of new lines, to local permitting and siting issues. Addressing these challenges will require policy changes not just at the federal level, where recent attention has been focused, but also in states and local communities.
