Zachary Gerson


I help clients get clean energy projects permitted, built and interconnected.

For more than a decade, Zach Gerson has brought his experience permitting some of the Northeast’s most significant clean energy projects and advancing the region’s clean energy policies to bear for clients looking to build clean and renewable energy resources.

Zach works extensively with offshore wind developers and developers of solar and energy storage assets to permit projects, comply with regulatory requirements, overcome interconnection challenges, and influence critical regulatory policy proceedings in Massachusetts.  He also advises clients with regard to financings, acquisitions, and sales that include clean energy assets.

Since 2010, Zach has worked with trailblazing offshore wind clients, including representing the Massachusetts Department of Energy Resources in long-term contract approval proceedings, Vineyard Wind in obtaining state, regional, and local permits for the Vineyard Wind 1 Project, and Avangrid Renewables in the state, regional, and local permitting of its Park City Wind and Commonwealth Wind projects.

Zach also has broad and deep experience helping solar and energy storage companies obtain necessary approvals and overcome regulatory challenges.  Zach has represented solar and energy storage developers and clean energy trade groups before the Massachusetts Department of Public Utilities in policy dockets that have shaped the Commonwealth’s clean energy landscape, including the “Grid Mod” dockets, major rate cases, and the proceedings to establish tariffs for the Solar Massachusetts Renewable Target (SMART) Program.  He regularly advises clients on net metering, the SMART Program, Renewable Portfolio Standards, and Massachusetts’s Clean Peak Energy Standard.
