RWE Empowers U.S. Battery Storage Growth: 3 New Projects Generating 190 MW, 770 MW Underway
RWE, committed to its Growing Green Strategy, has augmented its green energy presence in the U.S. by completing three new battery energy storage systems (BESS) with a total capacity of 190 MW (361 MWh). Additionally, there's an ongoing construction of a substantial 770 MW (2280 MWh) BESS. These new systems, named Bright Arrow, Big Star, and Mesquite 4, elevate RWE's U.S. battery storage capacity to approximately 512 MW (1370 MWh).
This achievement further solidifies RWE's position, with BESS constituting over a third of its 36 GW onshore wind, solar, and battery storage development pipeline in the U.S. Globally, RWE's battery storage capacity now exceeds 700 MW, with over 1 GW in battery storage projects currently under construction.

Andrew Flanagan, CEO of RWE Clean Energy, emphasized the growing significance of battery storage in facilitating the swift deployment of wind and solar projects, contributing to grid stability, and ensuring a reliable electric supply to meet demand. As part of the Growing Green Strategy, RWE aims to expand its global battery portfolio to 6 gigawatts by 2030, with the newly completed systems contributing to this ambitious goal.

The three new BESS, integrated with solar, act as efficient partners for renewables, storing surplus electricity generated for later grid release. Here's a brief overview:
1. Bright Arrow: A 100 MW (200 MWh) battery storage paired with a 300 MWac solar PV project in Sulphur Springs, Texas. Operational since December, it will join the ERCOT market, with solar electricity provided to an affiliate of NRG Energy, Inc.
2. Big Star: An 80 MW (120 MWh) battery storage coupled with a 200 MWac solar PV project in Bastrop County, Texas. Scheduled for commercial operation in March 2024, it will participate in the ERCOT market, supplying solar electricity to a third party.
3. Mesquite 4: A 10 MW (40 MWh) battery storage and 52.5 MWac solar project in Maricopa County, Arizona. Expected to come online this month, it will contribute to the Mesquite Complex's total operating capacity of approximately 530 MWac, with electricity services provided to Modesto Irrigation District (MID).
RWE, leveraging its internal expertise, ensures the safe and efficient operation of these assets. The company uses proprietary dispatch and optimization algorithms to maximize market value from its battery and renewable asset portfolio.
RWE's commitment to the energy transition extends globally, with plans to reach 6 GW of battery storage worldwide by 2030. The company has achieved milestones in Europe, Australia, and the U.S., including recent projects in the UK, Germany, and Australia, as well as connecting its largest U.S. battery storage system in California in 2023.
