Gregg Dixon bets on the power already here

Gregg Dixon’s introduction to alternative energy came with a domestic inconvenience: the sun kept its own schedule. Growing up in New Hampshire’s White Mountains, he lived with solar thermal systems and river-powered electricity, encouraged by a father who had been a GE engineer. In his later telling, the available hot water depended rather too heavily on the available sunshine. Energy was already a household subject, complete with practical consequences.

He did not march straight from that upbringing into a clean-energy career. Business and technology studies were followed by management consulting. A consulting assignment for Hess took him to a refinery on St. Croix. Later came a job selling on-site cogeneration. The calculation of what could be produced and used close to the customer brought his father’s interests back into focus. The dinner-table lesson had taken the scenic route.

That recurring interest in what is close at hand helps explain Dixon’s professional life. He helped build Voltus around the value of customers’ flexible electricity use and other distributed resources. After leaving its executive leadership, and subsequently its board under a regulatory settlement, he appeared in another energy venture. Again, the proposition involved finding a market for equipment already installed.

A salesman with an electricity problem

Dixon’s early energy work placed him on the commercial side of an industry whose language can repel perfectly intelligent people. At Hess Microgen, he led marketing and sales for on-site cogeneration systems. At EnerNOC, he became a senior marketing and sales executive. These were jobs in which understanding the machinery was only the beginning. A customer also needed to understand the bill.

His Boston College studies combined business administration and information systems. The combination suits the career that followed: technical enough to work with a connected asset, commercial enough to explain why its owner should care. Selling industrial energy services requires an answer to a wonderfully unsentimental question: what will this do for my business?

Demand response supplies one answer. A participating customer agrees to adjust electricity consumption when called upon under a program’s rules. That flexibility can help balance the grid and earn the customer money. The practical work includes arranging participation, measuring performance, and getting paid. The appealing word “virtual” still leaves everyone with real obligations.

Four hundred megawatts, and a small box

Voltus was founded in 2016. By its public launch in 2017, it had secured contracts for 400 megawatts of commercial and industrial load management. One early agreement involved Enerlogics and Duquesne Light in Pennsylvania. There was also an agreeably modest piece of hardware: a device assembled from standard components for about $100, running Linux and connected through Amazon Web Services.

The contrast gave the venture an intelligible shape. A relatively inexpensive connection at a customer site could become part of a much larger electricity resource. The business depended on bringing those individual arrangements together. Every meter represented a separate customer with a separate operation to protect.

Dixon liked a familiar comparison. In an investor presentation, he likened Voltus to Airbnb: a software marketplace connecting two sides and putting underused assets to work. Homes and visitors were replaced by distributed energy resources and electricity markets. It was an effective way into a complicated subject, provided one remembered that a grid dispatch has rather different consequences from a disappointing weekend rental.

His public explanations also grouped the opportunity into four categories: energy efficiency, demand response, distributed generation, and storage. Each offered a different relationship with the grid. Taken together, they made a case for looking beyond a conventional power station when considering where useful capacity might come from.

Turning that case into a business also meant negotiating access. In 2018, Voltus announced it had brought Michigan customers on competitive electricity supply into MISO demand response through alternative electric suppliers. It reported securing nearly 50 megawatts for that program year. Dixon described working closely with state commission staff. A technical connection to a meter was one part of the job; permission to participate in a particular market was another.

This helps explain the regulatory company Dixon kept. At a Voltus energy summit in April 2023, the announced speakers included former FERC chairmen Jon Wellinghoff and Neil Chatterjee, alongside Representative Sean Casten and Dixon. For a business built around opening electricity markets, the rules were an operating concern. The customer might see a payment, but behind it sat a chain of decisions about who could offer a service, how that service would be measured, and what the market would recognize.

“The most profitable outcome is the most probable outcome.”

The colleagues behind the capacity

Dixon’s public language about company culture could be strikingly personal. He talked about love and compassion, and about leaders admitting mistakes. “Love requires an incredibly deep level of vulnerability,” he said in a Voltus video. He connected that vulnerability to learning from errors and accepting colleagues as people.

In electricity, such language has to live alongside the dispatch schedule. A warm culture cannot substitute for an operating procedure. It can, at least as an aspiration, make it easier for somebody to admit that a procedure needs attention. His stated ideal was a team willing to be candid with itself.

A photograph he shared in 2021 offers a less formal version of the executive team. Colleagues perch among enormous tree roots. His accompanying account mentions early runs on the beach, late brainstorming, and the pleasure of reconnecting. The people he named included Matthew Plante, Dana Guernsey, Neil Lakin, Stephanie Hendricks, and former FERC chairman Jon Wellinghoff.

Those connections would continue to matter. Guernsey became his successor at Voltus. Hendricks would later lead AiGent. Electricity markets reward expertise that is difficult to acquire quickly; a new company can carry a considerable amount of old working history.

A pitch that reached the Garden

Some of the work escaped the conference-room diagram. In August 2022, Madison Square Garden announced a partnership with Voltus to implement demand response and identify energy reductions during peak usage and grid stress. For Dixon, the arena offered a recognizable example of the proposition: a building famous for what happened on its floor could also contribute through how it used electricity.

Other audiences required different explanations. Earlier that year, Voltus announced that Dixon would address a cryptocurrency mining conference in Texas. His scheduled presentation concerned power consumption, revenue, and load balancing. The title, “Don’t Mess With Texas,” at least spared the audience another session heading composed entirely of initials.

These were different doors into the same commercial argument. Electricity users have operating priorities of their own. A useful offer has to fit those priorities before it can contribute anything to the wider system.

The listing that stayed a proposal

There was also an attempt to take the business public through a merger with Broadscale Acquisition Corp. The agreement dated to November 2021. By August 2022, that path had closed: the parties terminated it by mutual written consent.

Broadscale disclosed that Voltus had said it could not complete all actions needed for the registration statement to become effective before the agreement’s deadline. The public-company future discussed in interviews remained a proposal. An announced transaction is one moment in a company’s life; a completed transaction is another.

Then, in January 2024, came a change in leadership. Dana Guernsey, a co-founder and chief product officer, became CEO. Dixon initially remained a director. At the handover, Voltus reported 5.8 gigawatts of integrated distributed energy resources across all nine US and Canadian wholesale markets.

The promise, and the settlement

The record also includes a serious regulatory chapter. On January 6, 2025, the Federal Energy Regulatory Commission approved a settlement with Voltus and Dixon concerning participation in the Midcontinent Independent System Operator market between October 2016 and June 2020.

Enforcement staff concluded that Dixon had engaged in a fraudulent scheme involving improperly obtained customer data and resources for which Voltus lacked contractual rights. Staff also concluded that Voltus registered resources without their knowledge or consent and cleared capacity that would not have performed if dispatched.

Voltus and Dixon stipulated to the settlement’s facts while neither admitting nor denying the alleged violations. Voltus agreed to return about $7.1 million in revenue and pay about $10.9 million in civil penalties. Dixon agreed to a $1 million civil penalty and to step down from the board.

That outcome belongs beside the company-building record. The service being sold depends on a customer’s permission and a resource’s ability to respond. The settlement concerned those foundations of the arrangement. A biography of its founder needs room for that consequence.

Back to the generator

By May 2025, Dixon was publicly identified as chairman of AiGent’s board. The company appointed Stephanie Hendricks CEO, drawing again on a colleague from Voltus. Its focus was distributed generation: coordinating existing equipment at commercial and industrial sites to provide services to power markets.

AiGent announced $6 million in seed funding that August. Under the name AGent Energy, it announced another $11 million financing in August 2026, bringing reported funding to $17 million. The newer company said it had delivered capacity during emergency events in PJM, MISO, and ERCOT. Its proposed resource was the backup equipment already standing at customer sites.

There is continuity in the choice. Dixon keeps returning to the space behind the electricity meter, where equipment bought for one purpose may have value for another. His career shows both the attraction of that idea and the responsibility that accompanies selling it. The next useful question remains wonderfully concrete: when somebody calls for the power, what happens?
