Mr. Rosenzweig’s siting expertise includes: electric transmission lines (underground, aboveground and underwater); natural gas, oil and coal-fired electric generating facilities; interstate and intrastate natural gas pipelines; and natural gas storage facilities. He has also represented the region’s first large-scale, off-shore wind power project in obtaining its state and local permits, licenses and siting approvals for energy infrastructure facilities from the Energy Facilities Siting Board, the Executive Office of Environmental Affairs pursuant to the Massachusetts Environmental Policy Act, the Department of Environmental Protection and various other state and local agencies, boards and governmental authorities.
He has also represented project developers in judicial proceedings in state and federal courts regarding challenges to permits and approvals initiated by project opponents.
Mr. Rosenzweig has also represented the region’s electric and natural gas distribution companies on all regulatory matters before the Massachusetts Department of Public Utilities. He has counseled electric distribution companies in industry restructuring proceedings to unbundle their distribution rates and to recover stranded costs, including securing regulatory approvals for the divestiture of their electric generating facilities.
Mr. Rosenzweig has negotiated electric and gas supply agreements for large institutional energy users and power sale agreements for wholesale electric generators. He has advised clients in restructurings, buydowns and buyouts of power sale agreements between competitive wholesale generators and electric distribution companies. In addition, he has counseled clients on transmission, power delivery and project interconnection issues concerning the New England Power Pool and the New England Independent System Operator.
