MISO

MISO (Midcontinent Independent System Operator) is an independent, not-for-profit, member-based organisation that manages the flow of high-voltage electricity across its region and operates one of the world's largest real-time energy markets. Headquartered in Carmel, Indiana, with additional offices in Little Rock, Arkansas, and Eagan, Minnesota, it is one of the nation's largest grid operators, serving more than 45 million people across portions of 15 states in the Midwest and the South.

The organisation's work spans several core functions. It runs the real-time energy markets that help maintain grid stability and efficiency, manages the high-voltage transmission network often described as an "electricity superhighway", plans for future transmission infrastructure, and coordinates with utilities and market participants to ensure reliability. Its technical domains extend to renewable energy integration, distributed energy resources, grid modernisation technology, the digitalisation of homes and distributed resources, and energy research.

As a member-based, mission-driven body, MISO describes its approach as combining research with advanced technology to support reliable and affordable power across the electric industry. Its work sits at the intersection of energy markets, grid infrastructure and emerging distributed technologies.
