Renewable energy company RWE Clean Energy has teamed up with specialist developer WhiteRock Renewables LLP to speed up the expansion of RWE’s onshore wind, solar and energy storage pipeline in the U.S.

As part of the partnership, WhiteRock will originate and develop between 4 gigawatts (GW) and 5 GW of onshore wind, solar and battery energy storage system projects, RWE said April 9 in a news release. RWE will have the option to acquire the projects once they reach maturity and are ready for a final investment decision.

“RWE is investing billions to expand our U.S. portfolio, which will make up 30% of the company’s global green installed capacity by 2030,” said Hanson Wood, senior vice president of utility-scale development for RWE Clean Energy. “To support our world-class development team in executing towards RWE’s ambitious U.S. growth strategy, we are enlisting WhiteRock—a top-tier developer with a proven track record of delivery and more than 70 years’ combined development experience—to help supercharge our growth trajectory over the next five years.”

RWE Clean Energy’s current net installed capacity in the U.S. is about 9 GW, but the company said it aims to increase that to more than 19 GW net by 2030.
