The new leader of the Maryland Public Service Commission said Tuesday that he plans to convene meetings with interested parties over the next few months to discuss the increasingly controversial issue of where to place renewable energy installations in the state. Testifying before a virtual hearing of the state Senate Committee on Education, Energy and the Environment, Fred Hoover, who took over as PSC chair in July, said he wanted to “get all the parties together to lower the temperature in some of these siting topics.”
