On a solar developer’s desk, sunshine is the least troublesome item. It arrives without a permit, ignores the interconnection queue and never asks counsel to redline a clause. Everything between a bright field and an operating project is less obliging. Matthew Kozey built his career in that difficult interval. He learned the statutes, watched a utility answer to regulators, argued for community-scale markets and eventually co-founded Arena Renewables, where paperwork is not the dull prelude to the business. It is the business.
Kozey’s route to the chief executive’s chair did not begin with panels. He studied political science at the University of North Carolina at Chapel Hill, stayed for a law degree and became admitted to the Maryland bar. His early résumé moved through the institutions that write, interpret and measure the energy system: the Federal Energy Regulatory Commission, an energy-law summer at Duane Morris, a legal fellowship with a House Foreign Affairs subcommittee and research work at NORC at the University of Chicago.
At NORC, he managed research for government clients, including weekly fuel-price surveys for the Energy Information Administration. It was orderly, unglamorous work with a revealing premise: energy is never just molecules or electrons. It is also data, public authority and the stories institutions tell about what the system is doing. Years later, Arena would use a related habit - study the market before entering it, then make decisions from evidence rather than enthusiasm.
Chapter 01The utility years
In 2013, Kozey joined Pepco Holdings as a regulatory strategy policy lead. He drafted testimony and assembled data for regulatory reporting in the power-delivery group. From 2016 to 2018, he managed regulatory affairs for the District of Columbia, overseeing Pepco’s work before the city’s Public Service Commission. Then he shifted again, becoming communications manager for Pepco in Washington and Maryland until April 2020.
That sequence matters. Regulation and communication are often treated as neighboring specialties, visited after the real decisions have been made. For a utility, they are part of the operating system. Rates, capital plans, reliability and public trust meet in commission rooms. A technically correct proposal still has to survive questions from regulators, advocates and customers. Kozey spent more than six years watching that translation happen from inside a Fortune 100 utility.
“Operating with these principles will lead to success, no matter what laws are on the books.”Matthew Kozey, after Arena’s first portfolio sale
He left Pepco for Cypress Creek Renewables in April 2020, taking charge of community-scale markets and focusing on policy development and advocacy around the country. By 2023 he had been named a senior director. In California’s community-renewables proceeding, he submitted formal testimony and took part in the debate over a new program that connected solar with storage. In an industry podcast, he described the significance of the state’s Assembly Bill 2316, particularly its storage requirement and focus on subscribers from lower-income communities.
His public argument was practical: distributed solar paired with batteries can be treated as a reliability resource, not merely as a green ornament. The grid needs electricity when people use it, not only when the sky offers it. Storage makes the timing negotiable. Policy decides whether projects that can provide that service are valued, delayed or stranded in a queue.
Chapter 02Enter the Arena
In 2023, Kozey joined Geoff Johnson and Patrick Grumley to start Arena Renewables. Johnson brought distributed-generation development experience; Grumley brought the scar tissue of operating high-growth companies. Kozey brought policy and market development. The trio named the company for the place where effort becomes visible and judgment becomes expensive.
Arena develops community and distributed solar and battery-storage projects. It finds promising markets and sites, reaches agreements with landowners, works through interconnection and permitting, lines up customers or offtake, and moves projects toward construction. The company can then transfer a de-risked portfolio to an owner with the capital and infrastructure to build and operate it. The panels may all resemble one another from the interstate. The projects underneath them do not.
There is a founder lesson hiding in this model. Arena did not pretend every link in the value chain rewards the same temperament. Owning power assets for decades is a capital business. Early development is a knowledge and execution business. Arena concentrated on the part where a senior team could create value by selecting the right markets, finding avoidable risks early and maintaining velocity through a process designed to lose momentum.
Chapter 03The unhurried meaning of velocity
Arena’s first portfolio sale makes the operating philosophy concrete. In May 2025, Summit Ridge Energy acquired six Illinois solar projects totaling 40 megawatts. Arena’s development team had spent roughly 18 months on diligence, local relationships and project work before the announcement. Kozey thanked Carson Weinand, Utkarsh Gupta, Patricia Murray and Tameem Jahan by name, then thanked the buyer for its professionalism.
Only after the acknowledgements did he offer a thesis. In an uncertain solar market, he wrote, a company still controls the quality of its hires, its choice of markets, its development execution and its integrity in negotiations. This is a sober founder’s list. There is no invitation to manifest a favorable commission order. There is simply a request to do the controllable things properly.
The distinction between haste and velocity is useful here. Haste sends a project into the wrong queue faster. Velocity is what remains after bad markets, weak sites and fuzzy agreements have been removed. A legal background helps, but not because every founder should become a lawyer. Kozey’s advantage is the habit that legal and regulatory work trained: read the language, identify who has authority, understand the sequence and notice which cheerful assumption has not yet become an enforceable fact.
Chapter 04A deal that kept the builders building
In April 2026, Headwater Energy acquired Arena Renewables. The transaction paired Arena’s development team and near-1 GW pipeline with Headwater’s financing and operating platform. Arena’s leaders remained in place. For Kozey, the attraction was not a ceremonial finish line. It was the chance to move projects from development to placed-in-service assets faster, with construction financing, tax equity and operational support closer at hand.
He framed the announcement as a team result and singled out his co-founders. The continuity is important. Development companies store much of their value in people’s judgment and relationships: which parcel deserves another month of work, which interconnection result changes the economics, which local concern needs a conversation rather than a slide deck. Buying the pipeline without preserving the team would be rather like buying a cookbook after dismissing the kitchen.
“With their capital and infrastructure behind us, we can move from development to placed-in-service assets faster.”Matthew Kozey, on joining Headwater Energy
The acquisition also completed a tidy arc. Kozey had spent his career learning why energy projects slow down: federal rules, state programs, utility obligations, public proceedings and the delicate choreography of communication. Arena converted that knowledge into a development platform. Headwater supplied the heavier capital machinery that comes after the early risks have been worked down.
Chapter 05The energy nerd and the Tornadoes
Kozey’s company biography cheerfully calls him a “proud energy nerd.” It also notes that he lives in Arlington, Virginia, with his wife and daughter and coaches his daughter’s soccer team, the Tornadoes. The detail rescues the résumé from its commission dockets. A person can spend Monday discussing battery integration and Saturday explaining why everyone must spread out.
It would be too neat to turn youth soccer into a management parable, and a coach deserves one place where megawatts do not intrude. Still, Kozey’s public voice is consistently attentive to teams. He names colleagues. He praises partners. He describes integrity as an operating choice, not a slogan applied after closing. Even his policy arguments invite utilities into the solution rather than treating them as cardboard villains.
What comes next is already embedded in the Headwater announcement: keep Arena operating, keep developing distributed photovoltaic and battery assets, and shorten the distance between an early project and one delivering electricity. The aspiration is less romantic than “change the world” and more measurable. Put sound projects into service. Do it faster. Retain the culture that made the platform worth acquiring.
Kozey’s story offers no magic trick for clean energy. It offers something more portable: a way to look at a regulated market. Study the rulebook until it stops looking like paperwork and starts looking like product design. Choose the part of the value chain where your experience changes the odds. Build a team that can tolerate long intervals between effort and applause. Then, when the bright field finally appears, remember who moved it through the queue.
