Octopus Energy Launches 'PowerStore' Battery Subscription Plan in Texas

Octopus Energy USA has introduced a new battery-backed retail electricity plan, "PowerStore," aimed at lowering upfront costs for Texas homeowners while integrating residential energy storage into the grid.

The plan offers customers a 30 kWh Lunar Energy battery system through a 36-month fixed-rate subscription with no upfront payment.

Under the program, customers pay a base electricity rate of 8 cents per kWh, excluding distribution utility charges, which typically add another 5 to 6 cents per kWh. The battery component comes with a $45 monthly subscription fee. At the end of the contract period, customers can either continue the service or take ownership of the battery system.

"The focus for the first customers is on your standard, hard-working American family looking to reduce out-of-pocket costs," said Ed Gunn, Vice President of Revenue at Lunar Energy. "This is a great option for them, because it's no money down and very straightforward."

The PowerStore plan aligns with Octopus Energy's broader strategy in Texas, where all its offerings are marked as "100% green energy" and supported by renewable energy certificates (RECs). Pricing is comparable to the company's existing plans, such as "Octo Simple 24," which offers similar per-kWh rates.

Like other battery-integrated retail plans in the state, PowerStore allows Octopus Energy to manage the battery system. The company uses stored energy to optimize household consumption and provide grid services, particularly during periods of peak demand.

In preparation for severe weather events, batteries will be charged ahead of anticipated outages, although the company does not guarantee a minimum backup reserve for unexpected disruptions.

The plan is compatible with existing solar installations and supports major inverter brands, including Enphase, Tesla, SolarEdge, and SMA. Customers can also sell excess solar energy back to the grid at a rate of 4 cents per kWh.

Octopus Energy's PowerStore plan reflects a growing shift toward integrated home energy systems that combine retail electricity with storage solutions. By removing upfront costs and bundling battery technology into a subscription model, the company is positioning itself to expand in Texas' competitive deregulated energy market while advancing grid flexibility and renewable energy adoption.
