Size your whole-home generator or LFP battery backup in Texas based on historical ERCOT (Electric Reliability Council of Texas) outage rates (19.4 hrs/yr) and local fuel rates.
Grid Authority: ERCOT (Electric Reliability Council of Texas) · Avg. Annual Outages: 19.4 hrs/yr
Winter freeze-offs (e.g. Winter Storm Uri), extreme summer heatwaves exceeding 85GW reserve margins.
Includes automatic transfer switch (ATS), subpanel interlock, and certified utility permit inspection.

Texas homeowners experience an average of $1,420 in economic disruptions per major outage event, driven by burst plumbing during winter freezes and refrigeration spoilage during prolonged summer heatwaves.
ERCOT operates as an energy-only islanded market with limited direct current ties to the Eastern and Western interconnections. When generation capacity trips during severe weather extremes, ERCOT must initiate load-shed blackouts to prevent total grid collapse.
A 22kW to 26kW whole-home standby generator running on natural gas or propane provides continuous power for dual central 4-ton HVAC units, refrigeration, and well pumps during multi-day ERCOT grid failures.
