Texas homes depend on a large, fast-changing power system. This reference page collects a small set of useful statewide figures in one place, with the original source and date next to every statistic.
These numbers give context for conversations about preparedness. They do not predict when an outage will happen, how long it will last, or what size generator is right for a specific home. For equipment planning, see Tipco’s home generator sizing guide or request an assessment.
Texas electricity at a glance
168,317 MW
Texas had 168,317 megawatts of net summer generating capacity in 2024.
That was the largest total among U.S. states in the federal annual profile.
566.5 million MWh
Texas generated 566,502,688 megawatthours of electricity in 2024.
The federal profile ranked Texas first among states for net generation that year.
505.4 million MWh
Texas retail electricity sales totaled 505,431,317 megawatthours in 2024.
This measures electricity sold to end users across the state, not home-generator output.
9.79¢ per kWh
Texas’s average retail electricity price was 9.79 cents per kilowatthour in 2024.
It is a statewide average across customer sectors, so an individual household bill can differ.
27+ million
ERCOT manages power flow for more than 27 million Texas customers.
ERCOT says its region represents about 90% of the state’s electric load.

83,707 MW
ERCOT’s 2025 summer peak-demand snapshot was 83,707 megawatts.
A peak-demand figure describes system demand at its highest point, not an outage prediction.
102,624 MW
ERCOT’s original 2026 firm-peak-load scenario was 102,624 megawatts.
This is a planning scenario reported by ERCOT, not a guarantee of actual demand or grid conditions.
How to use these figures
Statewide capacity, generation, sales and demand figures are useful for understanding scale. They do not replace a household load calculation. A backup-power plan still starts with the circuits and equipment that matter most to your home, then matches them to the generator and electrical connection.
For a portable-generator connection, an inlet box and the related electrical work can make selected circuits easier to use during an outage. For automatic backup, a standby generator is a different kind of system. Learn about generator inlet box installation or explore generator installation.
