What is NYISO?
New York Independent System Operator · serves New York State, ~20 million people
NYISO runs the grid for all of New York State. It's a tale of two systems: upstate is rich in hydro and increasingly wind, while downstate, including New York City and Long Island, is dense, constrained, and historically dependent on natural gas. Moving clean upstate power into the city is one of the state's biggest transmission challenges.
NYISO sits in the Eastern Interconnection and runs day-ahead and real-time markets with nodal pricing.
