Gravity Power:
Non-Explosive, Non-Flammable, Non-Degrading and Freely Available

Advanced Rail Energy Storage (ARES) uses proven rail technology to harness the power of gravity, providing a utility-scale storage solution at a cost that beats batteries. ARES’ highly efficient electric motors drive mass cars uphill, converting electric power to mechanical potential energy. When needed, mass cars are deployed downhill delivering electric power to the grid quickly and efficiently. ARES systems are machines and have a 40-year service life with no degradation and no thermal runaway.

Bolstering Renewable Energy Integration

ARES uses recycled steel rails, low-carbon and reclaimable mass cars, sophisticated motors and electronics, and freely available gravity, providing a fully sustainable renewable energy storage solution for utility-scale deployment.

Facilitating Grid Flexibility

ARES is ideal to provide ancillary services and other power functions making the modern electric grid more flexible and resilient as it navigates supply and demand  challenges including renewable resource integration, electric vehicles, voltage, frequency, outages, etc.

Pahrump Valley Times: Energy Storage Project Breaks Ground in Pahrump

A project nearly a full decade in the making, ARES Nevada LLC has finally moved the first shovelful of dirt to kick off construction of its brand new energy storage project, the ARES GravityLine, located right here in the Pahrump Valley, with an official groundbreaking ceremony hosted on Thursday, Oct. 8 in honor of the … Read more >

News Channel 3 Las Vegas: Pahrump gravel mine will store energy using carts, rails, and a big hill

LAS VEGAS (KSNV) — When most people think of energy storage, they probably think of a rechargeable battery: something that uses electricity to create a chemical reaction, which can later be reversed to power whatever it needs to. That’s far from the only way to store energy. Soon, a gravel mine located on the southern outskirts … Read more >
