Apex Brings Four New Projects Online, Totaling Over 625 MW

Charlottesville, VA - July 29, 2025 - Apex Clean Energy today announced that four utility-scale wind and storage projects totaling over 625 MW have reached commercial operations across Illinois, Maine, and Texas-bringing Apex's total operating and construction portfolio to over 3 GW.

These facilities-each of which came online in the first half of 2025-underscore the company's ability to deliver energy solutions across diverse markets and technologies. With a combined local economic impact of nearly $150 million and significant investments in conservation efforts for the regions surrounding these four projects through the Apex Conservation Grant Program, the operational facilities highlight clean power's role in supporting local economic and ecological resilience.

"From Maine to Texas, these sites reflect the strength of the Apex team and our ability to execute at scale-delivering the infrastructure our country needs at the moment it's needed most," said Ken Young, CEO of Apex Clean Energy. "As we continue to expand our operating portfolio, we're focused not only on supplying the grid with reliable, low-cost energy, but on maximizing the long-term value our projects create for the communities where we work."

More about the newly operational facilities:

• In Piatt County, Illinois, Prosperity Wind (300 MW) is Apex's fifth wind farm in the Prairie State and will generate around $93 million in tax revenue for the surrounding area, including $58 million for neighboring school districts. The facility is also providing $200,000 to support rewilding and restoration initiatives in Rockford and along the Illinois River.
• In Washington County, Maine, Downeast Wind (126 MW) marks Apex's first operational facility in the ISO New England market. In addition to creating close to $20 million in new revenue for the county and nearby town of Columbia, the project has already driven $156 million of direct, indirect, and induced economic activity statewide and has committed $126,000 to rebuild habitat for the federally endangered Atlantic salmon.
• In Hidalgo County, Texas, Great Kiskadee Storage (100 MW/200 MWh) is the first operational asset of SA Grid Solutions, a joint venture between Apex, SK Gas, and SK Eternix. The facility will enhance the reliability of the Texas grid and is expected to generate more than $23 million in tax revenue over its lifetime, in addition to contributing $100,000 to conserve 200 acres of wetland habitat.
• In Tom Green County, Texas, Angelo Storage (100 MW/200 MWh) is Apex's third storage facility to reach operations and its latest wholly owned grid asset. The project supports ERCOT's resilience by absorbing excess renewable generation and responding rapidly to demand and is projected to create more than $13.6 million in local tax revenue over its lifetime.
