What They Do

Clearway Energy Group specializes in developing, owning, and operating utility-scale renewable energy projects, focusing on solar, wind, and battery energy storage systems. The company also engages in some natural gas generation and thermal infrastructure through its affiliate. Their services encompass full-scope project development, which includes siting, permitting, construction, and long-term operations. This comprehensive approach allows them to offer community solar, distributed generation, and large-scale solar-plus-storage hybrids that effectively store excess renewable output for grid dispatch during peak demand (source: clearwayenergygroup.com).

Clearway's products include contracted power generation under long-term power purchase agreements (PPAs) with utilities, community choice aggregators, and corporate buyers. They deliver a range of energy services, including baseload, peaking, and thermal energy services like steam and chilled water via district systems. Their target markets span 28 U.S. states, serving utilities, regional transmission organizations, commercial and industrial customers, and corporate offtakers such as PepsiCo. The company is particularly focused on both regulated and deregulated regions, with significant development in solar (6 GW), wind (6 GW), and storage (4 GW paired/standalone) (source: clearwayenergygroup.com).

Clearway Energy Group distinguishes itself in the competitive landscape by holding over 10.7 GW of operating or in development storage assets across 16 states. They have a unique strategy of repurposing retired fossil fuel sites, such as those adjacent to former gas plants, and boast a 30 GW nationwide development pipeline. Their integrated solar-storage complexes enhance grid reliability, positioning them favorably against peers like Brookfield Renewable Partners and Atlantica Sustainable Infrastructure (source: key.com).

Projects & Track Record

Clearway Energy Group has completed several notable projects, including the Victory Pass and Arica solar-plus-storage complex in Riverside County, California. This project features 463 MW of solar capacity and 186 MW of battery storage, which became operational in 2023. It powers approximately 205,000 homes under contracts with various utilities and represents a $1 billion investment, contributing significantly to the local economy (source: clearwayenergygroup.com).

Another significant project is the Daggett Solar + Storage facility in San Bernardino County, California, which includes 482 MW of solar and 280 MW of storage, with plans to expand to 394 MW and 1.12 GWh by 2025. This project is notable for its location on a retired natural gas site and has been recognized as a POWER Top Plant for its innovative approach to repurposing fossil infrastructure (source: powermag.com).

Other highlights include the Rosamond Central Solar project, which has a capacity of 192 MW and powers 71,000 homes, and the Mililani II Solar + Storage project in Hawaii, which is the first utility-scale hybrid project on the island. Clearway also invested $660 million in the Texas Solar Nova project, which powers 190,000 homes (source: clearwayenergygroup.com). Ongoing projects include the Daggett BESS Phase 2, which is set to start construction in 2024 (source: clearwayenergygroup.com).

Recent Developments

In the past two years, Clearway Energy Group has made significant strides, including the launch of the Victory Pass and Arica complex in 2023, which has contributed $25.8 million in lifetime taxes and created 1,000 union construction jobs (source: clearwayenergygroup.com). In 2022, TotalEnergies acquired a 50% stake in Clearway from Global Infrastructure Partners, further strengthening its portfolio of over 10.4 GW of renewable energy assets (source: key.com).

The Daggett project has received accolades, including a POWER Top Plant award for its innovative approach to site repurposing, and has been highlighted by the American Clean Power Association as a model for renewable energy development (source: powermag.com). Clearway has also achieved milestones such as the retrofit of the Rosamond Central BESS and the expansion of its development pipeline to 30 GW, with over 12 GW of storage committed (source: clearwayenergygroup.com).
