He joined E3 in 2021 as a Director in our Climate Pathways and Electrification practice, applying his experience designing electrification and efficiency initiatives with state and local governments, electric and gas utilities, and large energy users. He focuses on practical solutions that reduce greenhouse gas emissions, deliver bankable energy and demand savings, increase resiliency, and capture the full benefit of new energy resources, management tools and emerging markets. Zak came to E3 from Willdan, E3’s parent company, where he was a Vice President of Corporate Business Development in Willdan’s Lower Manhattan office. Prior to Willdan, Zak was Risk Manager for a boutique environmental consultancy in New Jersey.

Zak is particularly interested in building and transport electrification, the future of natural gas, and the equitable transition of the power system.

A former collegiate pole vaulter, Zak stays on the ground more often these days running and cycling. He is a devoted Liverpool FC fan and an aspiring cook.

New York City Long-Term Energy Plan | New York City Mayor’s Office of Climate and Environmental Justice, 2022-2023

E3 led a team completing an inclusive, year-long study to identify the policies and programs needed to achieve the New York City’s decarbonization goals. E3’s analysis involved both examining policies and programs to meet the city’s long-term goals as well as providing specific recommendations for actions to be taken during the current administration. The study included eight research branches focused on the performance and cost of heat pumps in new buildings; the affordability of electrification retrofits in rent-regulated housing; the opportunities for electric school bus managed charging and vehicle-to-grid; the potential for in-city wind energy; a screening of public lands for new clean energy development; an assessment of the electric grid readiness for increasing heat pump and EV charging loads; and an evaluation of how bulk energy storage could reduce reliance on in-city fossil generation. Based on E3’s study, New York City published PowerUp NYC, the city’s first Long-Term Energy Plan, which includes 29 clean energy initiatives focused on the city’s energy grid, its buildings, and its transportation sector. Many aspects of the PowerUp NYC, from research topic selection to recommendations, were developed in collaboration with the public, and with the public’s interest at the forefront of the decision-making process. The recommendations of the LTEP are aligned with long-term energy and equity policy mandates from both the city and state and revolve around the needs of NYC residents.
