About Zac Leinheiser
ℎ ℎ ℎ.\" – I am Zac Leinheiser, an analyst with over five years of experience in Energy and Utilities. I believe true success is measured not by what we accumulate, but by the positive impact and opportunities we create for others.Beginning with municipal utility development, moving to natural gas consumer advocacy, and now my current role in transmission tariff pricing, I have consistently sought out opportunities where my skills in rate development and utility accounting can create positive, measurable outcomes for individuals and communities. Whether leading teams, modeling rates, or collaborating across departments, I strive to ensure my work contributes to a brighter, more sustainable future.My passion lies in organization, empowering leadership, and results. In my spare time I run casually and participate in road races. Personally, I am a football fan, love all things superhero-related, and enjoy movies — always happy to chat about any of these!I am constantly looking to connect with others who believe in the power of sustainable solutions and the importance of legacy in energy and utilities—feel free to start a conversation.
