Battery energy storage facilities provide instantaneous-start, dispatchable generation to help balance the intermittency of renewable energy as the electric grid transitions to low-to-zero-carbon resources.

In May of 2022, the company opened the largest battery energy storage facility in Texas co-located at a natural gas peaker plant. The DeCordova Energy Storage Facility in Granbury, Texas, is comprised of 22,360 individual battery modules. The facility stores enough electricity to power approximately 130,000 average Texas homes.

Battery Storage Operating in Illinois Today

Vistra operates battery energy storage at three Illinois plant sites. Each system is paired with utility-scale solar and is dispatchable to the grid.
Baldwin2 MW / 8 MWhRandolph County. Four hours of storage, paired with 68 MW of utility-scale solar.
Newton2 MW / 8 MWhJasper County. Four hours of storage, paired with 52 MW of utility-scale solar.
Coffeen2 MW / 8 MWhMontgomery County. Four hours of storage, paired with 44 MW of utility-scale solar.
Each was built at an existing Vistra plant property, reusing some of the transmission and interconnection assets already in place.

How Battery Energy Storage Supports Grid Reliability

How energy storage works: excess renewable generation charges utility-scale batteries, the batteries store it, and the facility releases it to the grid during peak demand.
Battery energy storage does one job: it holds electricity until the grid needs it.
Energy inSolar and windExcess renewable generation charges utility-scale batteries.
Energy storedBattery facilityThe batteries hold that energy until it is needed.
Energy outTo the gridThe facility releases the stored energy during periods of peak demand.
Because a battery facility starts instantly and can be dispatched on demand, it is available in the moments when demand peaks or renewable output drops — the same characteristic that lets it help balance the intermittency of solar and wind.

An Unyielding Commitment to Safe, Reliable Operations

There is no higher priority at Vistra than the safe operations of our power plants. The company is an experienced developer and operator of power plants of every fuel source and size. For nearly 140 years, our company has adapted to changes in technology to ensure our plants reliably produce electricity in a safe and environmentally responsible manner.

Vistra’s Battery Energy Storage facilities are planned around the company’s three safety principles:

  • Prevention
  • Detection
  • Mitigation
