Biography

Andrew Kaplan’s contributions to the energy industry have been nationally recognized. A leader in energy law and policy, he was a major architect of the current energy storage industry and an advocate for many of the regulations and rules that created today’s energy marketplace.

With over 25 years of experience from multiple perspectives, Andrew’s reputation as a trusted advisor and advocate has earned him credibility before federal and state regulators. As a former Chief of Staff and General Counsel at the Massachusetts Department of Public Utilities, he leverages his knowledge of the evolution of industry rules and competitive pressures to anticipate market trends, helping clients navigate next generation issues and working to develop, complete and operate energy projects using new technologies and industry paradigms.

More than a regulatory lawyer, Andrew is relied upon by boards of directors, C-suite executives, and senior management for strategic planning, business development and growth initiatives, regulatory affairs, governance, policy implementation and support of functions and operations company-wide. Having served as general counsel to a technology company, Andrew understands the business side of energy law.

He regularly represents clients before the Federal Energy Regulatory Commission (FERC), Independent System Operators/Regional Transmission Operators (NYISO, ISO-NE, PJM, Midcontinent ISO, California ISO, SPP and ERCOT), state public utility commissions, the U.S. Department of Energy and other governmental agencies to facilitate the approval process for federal, state, and local laws, regulations, and permits; assuring compliance with state siting requirements; and drafting and negotiating grid interconnection requirements.
