Contact our team today. We’re here to help.

We are stronger when we speak with a unified voice.

ACP is the voice of companies from across the clean power sector that are providing cost-effective solutions to the climate crisis while creating jobs, spurring investment in the American economy, and driving innovation across the country.

Renewable energy is operating at scale today and is expected to grow by 300% in the U.S. and by 500% globally in the next 30 years.

Many of our businesses are invested across the sector—wind, solar, transmission, and storage—a trend we expect will continue.

Bottom line, the renewable industry has evolved significantly, and it’s only natural that our trade associations should evolve with us. By uniting the power of the renewable energy industry, we are providing our members a higher ROI while fighting harder to make clean energy the leading source of power in the United States.

Information and best practices exchange

Chief Client Officer, Hannon Armstrong
ACP Incoming Board Chair

“Joining ACP as a founding member was an easy decision for our team. Renewable energy is a mainstream and mature source of American electric power. Clearly, we needed a united trade association to represent the breadth and depth of our industry. If we are to deliver a grid that is predominately powered by clean, reliable, and affordable renewable power, then we must continue to advocate as one cohesive group working together and playing off each other’s strengths.”
