Construction has officially commenced on the Rock Creek Solar Project, a large-scale renewable energy development in Clinton and Camanche, as well as Clinton County, Iowa. Once complete, the facility will deliver up to 150MW of clean, American-made solar power, complemented by 100MW of battery energy storage to enhance grid reliability. This is in contrast to the 200MW Goldfinch Solar Project also in Iowa that after 2 years has still not begun and has asked for an extension.
The US$320 million project is being developed by NextEra Energy Resources, one of the largest generators of renewable energy from wind and solar in North America. The company, a subsidiary of NextEra Energy, Inc., is also a leading developer of battery storage solutions, with a portfolio spanning the United States and Canada.
According to project plans, the Rock Creek facility will supply enough electricity to power nearly 30,000 homes. Local landowner Boysen, owner of MKJ Farms, has committed 220 acres of his farmland for the development. The project’s infrastructure will span multiple sites and integrate advanced solar technology to maximize efficiency.
Commercial operations are targeted for December 2026, marking another step in Iowa’s transition towards renewable energy and sustainable infrastructure investment.
NextEra Energy Resources, the renewable energy arm of NextEra Energy, is one of the largest clean energy developers tied to a U.S. utility. The company leads in large-scale solar and wind deployment, with projects across multiple states, including major sites in Florida, California, and Texas. Among its notable solar assets are the 265MW Dunns Bridge Solar Project and the 200MW Indiana Crossroads Solar Project in Northern Indiana, as well as the 100MW Point Beach Solar Energy Center in Wisconsin.
