Enel North America has significantly increased its operational large-scale energy storage capacity in Texas with the addition of five new battery energy storage systems (BESS) to the state’s electric grid. These additions provide an additional 369 MW/555 MWh of usable energy storage capacity, improving grid stability and reliability in a state experiencing unprecedented electricity demand due to extreme heat and population growth.
Enel’s total operational large-scale storage capacity is now 520 MW / 780 MWh, with a further expansion of 823 MW / 1,234 MWh expected next year. The expansion of Enel’s storage portfolio complements its commitment to strengthening the Texas electric grid, which includes 3.3 GW of installed solar and wind capacity, approximately 200 MW of demand-side management capacity and an energy retail business launched last year.
Enel’s large-scale batteries participate in ERCOT’s emergency services by providing power during grid emergencies and maintaining grid frequency. The high availability of Enel’s BESS operational assets ensures that up to 325 MW of electricity can be stored and discharged in seconds, equivalent to supplying approximately 65,000 households during peak demand.
Increasing battery storage capacity in Texas demonstrates Enel’s continued commitment to strengthening the state’s energy infrastructure. Battery energy storage systems play a critical role in keeping energy prices affordable by storing electricity during times of low demand and releasing it during peak demand, reducing the risk of grid outages.
Enel North America is a leader in clean energy in North America and is actively working to accelerate the adoption of clean energy solutions. With more than 9.7 GW of large-scale renewable capacity and significant energy storage and demand response capabilities, Enel plays a critical role in decarbonizing energy supplies, electrifying transportation and building resilient networks.
