Daily electricity demand: ERCOT, PJM, MISO, CAISO and more
Updated Oct 10, 2026
EIA-930 data to Oct 9, 2026 · fetched Oct 10, 2026 · checked daily
In the 30 days to Oct 9, 2026, ERCOT demand averaged 1,585 GWh a day, +8.7% vs the same 30 days a year earlier; the highest day in our data since 2019 was 1,825 GWh on Aug 24, 2026.
Source: U.S. Energy Information Administration (EIA-930 Hourly Electric Grid Monitor). Each day is cut at midnight Central time so the operators are comparable. EIA-930 data are preliminary and can be revised. Averages and changes are our calculation. Demand is not the same as price or your bill.Source: TexasHomeBills™ — https://texashomebills.com/data/grid-demand

GWh per Central-time day. The 30-day average ends on the operator’s latest day; “vs year earlier” compares it with the same 30 days 364 days before, and weather explains much of the difference. “Highest day” is the highest daily total in our history since January 2019, not the peak hour and not necessarily an all-time record. Days EIA did not publish are left empty, not filled.
The numbers are the EIA’s daily demand by balancing authority from the EIA-930 Hourly Electric Grid Monitor: the sum of the hourly demand each operator reports, with every day cut at midnight Central time. EIA-930 data are preliminary; we re-read the last 45 days every day and keep earlier values when EIA revises one.
Demand is the electricity a grid operator’s area uses, not what customers pay. For prices see the ERCOT, EIA and plan pages; for EIA’s projections see the energy outlook page. Energy outlook →
Frequently asked questions
How much electricity does ERCOT use in a day?
In the 30 days to the latest day in our data, ERCOT demand averaged the figure shown at the top of this page, in GWh per day. The table also shows the highest day since 2019.
Is this the peak demand record?
No. These are daily totals. ERCOT’s peak demand record is the highest hour; see the large-load and peak demand page.
