What is MISO?

Midcontinent Independent System Operator · serves 15 states + Manitoba

MISO coordinates the grid across 15 US states and the Canadian province of Manitoba, running a long north-south footprint through the middle of the continent. It's a wind-rich system because the Great Plains are some of the best onshore wind territory on Earth, and it's a major mover of power between regions.

MISO sits inside the Eastern Interconnection and runs energy and capacity markets. Its scale lets it pool reserves across a huge area, smoothing out local weather and demand swings.
