GridVigil tracks electricity demand, capacity margin, and grid pressure for 10 U.S. grid regions — every major ISO/RTO plus three non-ISO groupings — built from real EIA, NOAA, and grid-operator data.
ERCOT Grid Status — ERCOT (the Electric Reliability Council of Texas) operates the electric grid and wholesale electricity market covering roughly 90% of Texas's electric load.
PJM Grid Status — PJM Interconnection is a regional transmission organization coordinating the wholesale electricity market across all or part of 13 states — Pennsylvania, New Jersey, Maryland, Delaware, Virginia, Ohio, West Virginia, Kentucky, Illinois, Indiana, North Carolina, Michigan, and Tennessee — plus Washington, D.C.
CAISO Grid Status — CAISO (the California Independent System Operator) operates the power grid and wholesale electricity market for most of California.
MISO Grid Status — MISO (the Midcontinent Independent System Operator) coordinates the wholesale electricity market across a north-south footprint running from Minnesota and Wisconsin down through Missouri, Arkansas, Louisiana, and Mississippi.
SPP Grid Status — SPP (the Southwest Power Pool) is a regional transmission organization coordinating the wholesale electricity market across a swath of the central U.S.
NYISO Grid Status — NYISO (the New York Independent System Operator) operates New York State's bulk power grid and wholesale electricity markets.
ISO-NE Grid Status — ISO-NE (ISO New England) operates the power grid and wholesale electricity markets across the six New England states — Massachusetts, Connecticut, Rhode Island, New Hampshire, Vermont, and Maine.
Southeast Grid Status — GridVigil groups Georgia, Alabama, South Carolina, North Carolina, Tennessee, and Mississippi as "Southeast" because this part of the country is served by vertically-integrated utilities rather than a centralized ISO/RTO wholesale market.
Mountain West Grid Status — GridVigil groups Washington, Oregon, Idaho, Montana, Wyoming, Nevada, Utah, Colorado, and Arizona as "Mountain West" — states outside CAISO served largely by vertically-integrated utilities rather than a centralized ISO/RTO wholesale market.
Florida Grid Status — Florida is part of the FRCC (Florida Reliability Coordinating Council) NERC region and is served by vertically-integrated utilities rather than a centralized ISO/RTO wholesale market.
