From Houston to Texas homeowners
One Battery.
Three Jobs.
Most people buy a battery for backup. Ours is built to do more: keep your lights on, cut your bill, and get paid when Texas needs power.
Three jobs, one battery
Built to work every day, not just during outages.
A backup battery sits idle most of the year. Ours earns its keep around the clock.
Backup power
Keeps the lights on
When the grid goes down, your battery takes over automatically. No generator. No fuel. No noise.
Energy arbitrage
Charges cheap, runs on savings
Your battery fills up when wholesale power is cheapest, usually midday, then runs your home through the expensive evening hours.
Grid services
Gets paid when Texas needs it
When ERCOT prices spike, your battery can sell power back to the grid. Your home becomes a small power plant that pays you.

Why it works in Texas
Texas power prices swing all day. Your battery takes advantage.
On the ERCOT grid, wholesale prices are often lowest around midday and highest in the evening, with occasional sharp spikes when demand peaks.
Your battery buys low, powers your home when prices climb, and sells back when the grid is short. All automatically.

Why add a battery to my home?
Outages are only getting more common, and most of the damage happens close to home: downed lines and blown transformers on the distribution network, not the transmission grid. There’s far more of that infrastructure to harden, and it’s slow, expensive work. About 1 in 4 households nationwide, 33.9 million, went without power at least once in the year before the 2023 American Housing Survey. When the power goes out, so does your refrigerator: the FDA says refrigerated food is unsafe after 4 hours, and the CDC says to toss refrigerated medication after a day. Add in a hotel room or missed work, and a single outage gets expensive fast.
Texas is also adding solar faster than any other state, which is reshaping when power is cheap. ERCOT has about 52 GW of solar today against 56 GW of gas; by 2035 solar pulls ahead, near 64 GW to 61 GW. That’s great at noon and a problem after dark, since gas has to pick up the slack once the sun sets, and gas isn’t free. A battery stores the cheap midday power and uses it through the expensive evening and overnight hours.
On top of that daily swing, overall demand on the grid keeps climbing too, from population growth, EVs, and new industrial and data center load. That pushes peak prices up further, year after year.
Why not just put solar panels on my roof?
Rooftop solar competes with exactly the power that is already cheapest. Utility-scale solar farms track the sun, face it directly, and run at more than double the efficiency of a panel bolted to a roof that may face the wrong direction or sit in shade part of the day. Add in the cost of cleaning and servicing rooftop panels, the risk of roof leaks from a bad install, and the bump in your home insurance, and the economics get harder to justify.
Because wholesale prices are already low during the exact hours your roof would be generating, home solar mostly saves you money competing with power that is nearly free anyway. A battery does the opposite. It buys power when it is cheap and uses it when prices, and value, are highest.
Why not just go with Base Power?
Base Power’s model works by taking over your battery, not by selling you one. In Texas, a battery that can run at full output for about four hours makes strong economic sense: charge during cheap daytime hours, discharge during expensive evenings.
ERCOT’s battery fleet is expected to grow from about 27 GW to 33 GW by 2035 on the strength of that math, and businesses that build standalone battery projects can see returns above 15%. But those businesses have to buy land, secure environmental permits, run grid studies, and arrange their own interconnection. That is expensive and slow.
Base Power’s answer was to use your land and your grid connection instead. They own the battery, keep control of when it charges and discharges, charge you an upfront installation fee, and pass you a flat, average retail rate while they keep the trading profit.
We think the upside should be yours. Buy your system outright, or finance it on a monthly plan that fits your budget, and the savings and earnings it generates belong to you.
Are these batteries safe?
Battery chemistry has come a long way. We use LiFePO4, lithium iron phosphate cells, chosen across the industry specifically because it is thermally stable. It is a different chemistry from the nickel cobalt aluminum cells in early Tesla EVs that you may have read about catching fire.
LFP is widely considered the safest lithium-ion chemistry available today, and our systems are engineered to UL 1973 and UL 9540 safety standards, the industry benchmark for battery and energy storage safety. You can read more about lithium-ion safety at Battery University.
