MISO estimates its savings and efficiencies benefited its members to the tune of just over $5 billion in 2024.
It’s the first time MISO’s annual Value Proposition has averaged above $5 billion, though benefits in 2023 came close. (See MISO Estimates 2023 Member Savings Near $5B.) MISO said the 2024 range of cost savings is anywhere from $4.52 billion to $5.75 billion. The RTO subtracts membership dues from overall benefit estimates.
The RTO estimates its membership benefits annually through its Value Proposition study, where it attempts to quantify the benefits of its membership against non-RTO entities. MISO does not track cost savings to individual market participants but said members could expect $15 in savings to every dollar spent on MISO membership in 2024.
Per usual, the bulk of the savings (this time anywhere from $2.9 billion to $3.9 billion) is derived from members’ access to capacity sharing across MISO’s large geographic footprint. Efficiency gains from MISO’s energy and ancillary service markets rank second at anywhere from $881 million to $974 million. MISO’s ability to optimize the use of members’ renewable resources through grid planning again took third place at $403 million to $474 million.
MISO said its reliability category was on average less beneficial in 2024 ($337 million) than it was in 2023 ($346 million) because 2024 held fewer extreme weather conditions.
MISO said the value of its membership is poised to increase over the coming years as the fleet decarbonizes. It estimated cumulative benefits at $50 billion since 2007, when it first began producing the annual approximation.
In a press release, Senior Vice President and Chief Strategy Officer Andre Porter said members benefit from MISO’s “market efficiencies, grid planning and operational enhancements across a large and diverse footprint.”
