Guide
Two events reset how Texas thinks about backup power. Here is what they taught site managers, and where a battery fits in the plan.
Texas runs its own grid. Most of the state is served by ERCOT, which has limited connections to neighbouring grids, so when supply falls short there is little to import. In February 2021, Winter Storm Uri forced rotating outages that left millions of Texans without power, some for days.
In July 2024, Hurricane Beryl knocked out power to more than two million customers in the Houston area. Both events showed the same weak point in standby generator plans: fuel. Frozen or flooded roads, closed depots and queues at the pumps stop a generator long before its engine fails.
A charged battery has nothing left to deliver. Stage it before a forecast event and it carries critical loads straight away, silently and with no carbon monoxide, so it can sit beside the building. Once the grid or a road is back, it recharges from shore power, an existing generator or solar.
For outages longer than one charge, the hybrid approach works best: the battery carries the load and a right-sized generator starts only to recharge it. Fuel use drops sharply and the generator runs in its efficient band while it does run.
List what must stay on, the power each item draws and how many hours you need it. That gives the power (kW) and energy (kWh) the system must cover. Our guide on how to size a BESS walks through it, or send us the list and we will size it for you.
PulseTrek builds every unit in Liberty Hill, north-west of Austin, so Texas sites get the shortest delivery runs. See Texas service areas.
Questions answered
It depends on the load and the outage length. For critical loads that must run through a storm without refuelling, a battery staged in advance is the most dependable option. For long outages, a battery with a small generator that runs only to recharge covers both.
Yes. A charged battery runs independently of the grid, carrying your critical loads until power returns, and recharges from shore power, a generator or solar.
Divide 30 kWh by the average load. A 2 kW critical load runs for roughly 12 to 15 hours; lighter loads run for days.
