Chief Client Officer, HASI
ACP 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.”
