U.S. Power Grids Ranked by Pressure Score: ERCOT, PJM, CAISO, MISO, SPP, NYISO, ISO-NE and More (GridVigil)

gridvigil/list-grids

Lists all ten U.S. power grid regions GridVigil tracks (ERCOT, PJM, CAISO, MISO, SPP, NYISO, ISO-NE and the Southeast, Mountain West and Florida non-ISO groupings) with, for each, its 0 to 100 power pressure score and band, the latest hourly demand in megawatts, the official reserve margin where one exists, the states it covers and the grid id to use with the other GridVigil tools. Data from GridVigil (gridvigil.com), built on EIA, operator and NOAA public data. Served by Eden Engine; not an official GridVigil product.
