Mr. Ain began his professional journey in public service, first as legislative counsel in the U.S. House of Representatives and subsequently as counsel to the House Energy and Commerce Committee during the drafting of critical energy legislation in the 1970s. He later served as Associate General Counsel at the Federal Energy Regulatory Commission (FERC), where he led initiatives that laid the groundwork for the independent power sector. From 1980 to 1994, Mr. Ain was a partner at the Washington, D.C.–based law firm Van Ness Feldman, where he advised developers in the renewable energy and cogeneration space.
