Solar Generation and Storage

Next Generation Projects

At Copia, development never stops. With a robust 30 GW+ pipeline, we are always preparing the next wave of projects that will move from development to construction. Our upcoming builds reflect years of disciplined siting, permitting, interconnection planning, and community engagement — enabling us to advance projects quickly and responsibly.

These “next generation” projects provide both confidence and momentum behind our gigawatt-campus model. They are where planning turns into action, continuing Copia’s track record of transforming capital, strategy, and partnerships into real, operating assets.
