LFP-based Aries Grid is capable of powering factories, data centers, communities — even stabilizing the power grid — with 100% renewable energy.

This is Aries Grid

Aries Grid

Made from abundant iron.

Aries Grid uses LFP chemistry based on safe, abundant iron. Aries Grid means extremely durable, 100% renewable, 24/7 energy storage is now possible nearly everywhere.

Customizable cells and modules for stationary storage.

ONE cells and modules are built in the U.S. and available now for your stationary storage application. The GE Vernova FLEXRESERVOIR energy storage system will be built with customized ONE cells and modules.


Top terminal prismatic LFP cell engineered for 8,000 cycles. UL certified for utlity-scale applications.

Aries LFP

Available in 79 kWh and 105 kWh modules configured for stationary storage. Produced at scale in Michigan.

Customizable ESS

The entire Aries Grid system can be customized for your application.

Durable and affordable.

By offering more durability at a lower cost, Aries Grid changes the equation — offering a world of possibilities.

More cost effective too.

Aries Grid uses our Aries LFP battery technology, which is already in-market. That means lower execution risk and greater economies of scale. Costs are cut even further by federal tax incentives.

Time travel for green energy.

Aries Grid means you can now use 10:00 AM sunshine power in the middle of the night. Every Aries Grid container holds 45 durable, cost-effective, tried-and-true Aries LFP EV packs — enough energy storage to power 45 class 5 trucks. The bottom line is Aries Grid lets you use far more renewable energy than you could before — whenever you want to use it.

Distribute and decentralize.

Because Aries Grid supplies uninterruptible power, microgrids can now be decentralized and distributed. And with lower cost, you can create more islanded microgrids in more places than was ever possible before.

Renewable energy anytime, anywhere.

Aries Grid can help provide 100% renewable energy 100% of the time — everywhere in America and around the world.

Made with safe and sustainable LFP.

Aries Grid uses lithium iron phosphate chemistry (LFP) sourced from stable and locally abundant iron instead of rare nickel and cobalt. LFP enables more competitive pricing, safer energy storage and a sustainable supply chain.


Fast fleet charging.

Aries Grid DC Fast Charge overcomes infrastructure power constraints.

  • Eliminate lead times to upgrading power service capabilities

  • Increase charging capacity both in units and power

  • Participate in grid response programs for additional revenue opportunities while supporting grid stabilization

  • Each Aries Grid DC Fast Charge container can support up to 20 buses, charging at 20-30kW each

An Aries Grid solution for every use case.

Aries Grid creates value different ways depending on the project. Heavy industry may benefit more from bill management, while manufacturers may benefit more from frequency regulation. Here are some of the many Aries Grid revenue streams:

  • Energy arbitrage

  • Demand response — wholesale

  • Frequency regulation

  • Demand response — utility

  • Spinning/non-spinning reserves

  • Bill management

  • Resource adequacy

  • Local incentive payments

  • Distribution deferral

Aries Grid is turning coal country green.

ONE is partnering with BHE Renewables, Precision Castparts, Corp. and the people of Jackson County, West Virginia to create the world’s largest solar and storage microgrid. This coal country community is embracing renewables to bring good manufacturing jobs back to their state.

  • BHE Renewables is building a global aerospace manufacturing hub and a solar farm with seven times the number of solar panels in West Virginia today.

  • ONE will store and deliver 100% renewable energy 24/7 with Aries Grid.

  • Precision Castparts Corp. and their new TIMET facility will produce titanium and good jobs for West Virginians.

The partnership will save West Virginians from two million metric tons of carbon dioxide emissions — the equivalent of taking half a million vehicles off the road for an entire year.

Aries Grid — going live this year.
