Greer Mackebee – BrightNight

Greer Mackebee likes to joke that his most important career skill was sharpened long before he ever stepped into a law school classroom or negotiated a complex power purchase agreement. It began instead under hot studio lights in Culver City, waiting for a buzzer, standing at a podium next to the woman who would later become his wife. Their story started in 2012, when both were contestants on Jeopardy!, chosen from the same in-person audition and seated next to each other on the shuttle bus to the studio. They exchanged a few hopeful smiles and phone numbers, then went their separate ways. Years later, through what he calls a series of unexpected turns, they found themselves living in Washington, D.C., reconnecting and eventually building a life together.

Jeopardy has continued to weave through their shared story. In 2024, they competed again, this time on Pop Culture Jeopardy, hosted by Colin Jost. Mackebee laughs when he reflects on it, noting that the real prize was never the dollars or the bragging rights.

“It sounds funny, but the ability to hear a question, decide what matters, and respond quickly has helped me tremendously as a lawyer,” he says.

That instinct has followed him throughout his career. Today, as vice president and deputy general counsel for BrightNight, Mackebee uses the same mix of calm focus, quick judgment, and curiosity to help build some of the most advanced energy and digital infrastructure projects in the country. It is a surprising journey for someone who once thought he was headed toward a PhD in environmental engineering, but Mackebee’s path has always bent toward impact. Law simply became the tool that allowed him to reach it.

Finding the right path

Mackebee grew up in Knoxville, Tennessee, where environmental issues were not theoretical classroom discussions but lived experiences tied to his own backyard. While studying civil and environmental engineering at Duke University, he conducted research on coal combustion byproducts, work inspired by a massive coal ash spill in Kingston, only 25 miles from where he grew up. He published research and began imagining an academic future centered on understanding the science behind environmental disasters.

As he read more about the aftermath of the spill and the court battles surrounding it, he found himself drawn not only to the chemistry but to the policies and legal questions shaping the response. Who was responsible? What would accountability look like? How would long-term impacts be measured and addressed? These questions stayed with him.

Maybe I should look into law school, he remembers thinking. He imagined becoming an environmental impact litigator, someone who could blend technical knowledge with a drive to represent communities.

During law school at Stanford, he pursued that path, even spending a summer clerking at the Department of Justice in Washington, D.C., working on appellate environmental cases on behalf of the EPA. But the experience also clarified what did not fit.

“I realized trial or appellate work wouldn’t be the right direction for me,” he says. “I wanted to feel connected to something being built. I liked the idea of tangible outcomes.”

That shift led him toward transactional work in the energy sector and eventually into private practice at firms known for their project finance and renewable energy teams. He discovered that each project offered new challenges, new technologies, and new ways to blend engineering instincts with legal strategy. The work was technical, fast-moving, and collaborative. It was also the first time he saw how legal expertise could help determine whether a clean energy project made it from concept to construction.

Building a foundation in renewable energy

Mackebee stayed in private practice longer than he expected. He worked with talented teams at Orrick, Herrington & Sutcliffe LLP and Amis, Patel & Brewer, LLP, gained exposure to a wide array of transactions, and built a toolkit that would later shape his approach as an in-house advisor. But over time, he felt a pull toward something more holistic.

In a firm, he explains, his role often began when a company decided to move forward with a project and ended once the early legal work was complete.

“I found myself wanting to be more involved in the projects, more so than the role a firm lawyer can play,” he says.

He wanted to follow a project throughout its full life cycle, from the first conversation with a potential customer to the moment the plant began producing power and beyond.

By the time a headhunter approached him about a role at BrightNight, he already knew of the company and admired its work. BrightNight is a next-generation power and digital infrastructure company serving utilities, data centers, and commercial and industrial customers. The company develops and operates large-scale energy sites that integrate utility-scale renewables, advanced gas generation, battery storage, and digital infrastructure hubs. Its portfolio includes power projects in some of the United States’ fastest-growing energy and data center markets. Its customer-focused development approach and AI platform, PowerAlphaÒ, help optimize economics, performance, and uptime.

The company had no legal department at the time. It needed someone who could work across both business development and legal strategy, someone comfortable navigating uncertainty and problem-solving from multiple angles. To Mackebee, that environment felt electric.

“When I joined, we were smaller and incredibly hands-on,” he says. “The opportunity to come in and have influence while the company was growing was exciting to me.”

He began on the origination side, working directly with customers and negotiating commercial terms while quietly performing many of the internal legal tasks that arise in a rapidly scaling company. When BrightNight formally established its legal team, Mackebee joined it, eventually becoming vice president and deputy general counsel.

Shaping projects from start to finish

Today, Mackebee’s work spans the full spectrum of project development. He supports power purchase agreements, build-transfer agreements, construction contracts, equipment procurement, construction debt financing, tax equity structures, and internal corporate matters. He manages outside counsel, partners daily with the general counsel and upper management, and supports virtually every corner of BrightNight’s operations.

His engineering background still shapes how he thinks about problems. He breaks issues into components, asks what inputs matter most, and searches for creative solutions that respect both legal boundaries and commercial realities. He believes one of his strengths is knowing when to pause and ask the right questions.

“I enjoy getting deals done, but I also enjoy the challenge of figuring out how to get there,” he says. “Every project is different, and every solution requires a different mix of experience and perspective.”

One of his most formative experiences at BrightNight was the Box Canyon project in Arizona, the company’s first major development and a milestone for the team as it reached commercial operation in June 2025. He played a leading role in structuring the commercial terms and supported equipment sourcing, construction, financing, operations, and maintenance.

Coming from private practice, where he saw only a slice of any project, it was powerful to help shepherd something from a term sheet to an operation. It also reinforced his excitement for the company’s mission. Box Canyon has since been followed by projects like Pioneer in Arizona and Greenwater in Washington State, both of which have recently achieved financial close, along with many others moving toward 2026 and beyond.

BrightNight’s portfolio is substantial, with more than 35 gigawatts total in its pipeline. The company continues to grow quickly, supported by a lean legal team in the United States and additional attorneys in India. Mackebee’s challenge has been to scale his responsibilities without losing touch with the hands-on legal work he values most.

Preparing for what comes next

Energy markets continue to evolve, shaped by shifting political dynamics, data center demand, and technological advances. Yet Mackebee believes BrightNight is positioned to thrive. Its ability to work across multiple technologies and tailor solutions to specific customer problems gives it a strategic advantage.

He is equally optimistic about his own role. The breadth of work, the collaboration across teams, and the evolving structure of the legal department all align with the career he hoped to build when he first stepped away from academia.

“There is always something left at the end of the day, something tangible at the end of the work I do,” he says.

A decade after sitting on a Jeopardy shuttle next to the woman he would one day marry, Mackebee still approaches challenges with the same clarity and speed that carried him across a TV studio stage. Only now are those quick decisions helping shape energy projects that will power communities, support digital infrastructure, and contribute to a cleaner, more resilient grid.

And in a world where the right answer can define the future of a project, the skill that once helped him ring in before other contestants has become a defining part of his work.
