Marshall Coover

Marshall Coover is a public affairs and external relations professional with extensive experience
guiding companies through the political, regulatory, and community environments that shape large-scale energy and infrastructure development.
Based in Austin, he has built his career at the intersection of state policy, local government, and corporate strategy, helping organizations advance complex initiatives in fast-moving and often sensitive environments.
Most recently, Marshall served as Senior Director of Public Affairs and External Relations at Treaty Oak Clean Energy, a Macquarie-backed independent power producer. In that role, he led government relations, community engagement, and public affairs strategy for a portfolio of more than 30
projects totaling approximately 17 GW of utility-scale solar and battery storage capacity across
Texas, Georgia, Louisiana, South Carolina, and other key markets. His work included navigating
high-stakes permitting and siting processes, securing county-level tax incentives, and engaging on legislative and regulatory issues with material implications for grid reliability and investment outcomes.
Marshall’s perspective is informed by experience both inside and outside government.

Early in his career, he worked in Texas state government and environmental regulation, gaining first-hand familiarity with how policy is developed, how agencies operate, and how regulatory decisions
translate into real-world impacts. He later brought that expertise to the private sector as a contract
lobbyist and regulatory consultant with a bipartisan Texas government affairs firm, advising clients on energy, infrastructure, and environmental policy.

Today, Marshall works closely with large electricity consumers and developers on stakeholder
strategy, risk mitigation, and public-sector engagement related to generation, storage, and
transmission needed to meet accelerating load growth. His work emphasizes practical policy
pathways that enable timely, cost-effective deployment of energy resources while maintaining
community trust.

Marshall holds a JD from Texas Tech University School of Law and an MBA from the McCombs
School of Business at the University of Texas at Austin. He is a licensed attorney in the State of
Texas. Originally from Corpus Christi, he brings a grounded, community-oriented perspective
shaped by his Gulf Coast upbringing. He lives in Austin with his family
