Are Utilities Blocking Virtual Power Plant Access?
Utilities are hindering VPP access by blocking meter data—what's the path forward? Explore the antitrust implications and solutions!
The promise of virtual power plants is straightforward: aggregate distributed energy resources — rooftop solar, home batteries, EV chargers, smart thermostats — into a coordinated grid asset that can compete with a peaker plant. No new steel in the ground. No transmission corridors. Just software, coordination, and the assets already sitting behind millions of meters across the country.
So why can't VPP aggregators actually get this off the ground at scale? According to two industry groups, the answer is deliberate obstruction — and they're calling for antitrust law to force the issue open.
What a Virtual Power Plant Actually Does
A VPP isn't a building. It's a system. When a grid operator signals that demand is spiking — say, on a 98-degree afternoon in Phoenix — a VPP aggregator sends instructions to thousands of enrolled devices simultaneously. Pre-cooled homes raise their thermostat setpoints by two degrees. Batteries dispatch stored solar power back to the grid. EV chargers pause. The net effect can equal hundreds of megawatts of demand reduction or supply injection, delivered in minutes, without firing up a single gas turbine.
That flexibility is exactly what grid operators need as variable renewable penetration increases and dispatchable capacity becomes harder to site and permit. The Rocky Mountain Institute has estimated that VPPs could provide 60 gigawatts of peak capacity in the U.S. by 2030 — roughly equivalent to 10% of current peak demand — if the market conditions allow it.
The operative phrase being: if.
What Utilities Are Actually Doing
To run a VPP, an aggregator needs granular, real-time data from the meters attached to their enrolled customers' homes and businesses. Specifically, they need utilities' meter data — interval consumption and production readings — to dispatch resources accurately, verify performance, and settle payments with grid operators.
This is where things get uncomfortable. The two groups raising alarms allege that utilities are systematically denying or delaying VPP aggregators' access to exactly this data — the same data that flows freely to the utilities themselves and their affiliated retail subsidiaries.
The pattern isn't unique to one region or one utility. It's structural. Utilities control both the metering infrastructure and the data pipelines that serve it. An aggregator trying to build a VPP program across a large investor-owned utility territory has to negotiate access terms with the very company that competes with them in the demand response and grid services market. That's not a coincidence. That's leverage.
When the gatekeeper is also a competitor, "access" tends to come with delays, technical barriers, and quietly prohibitive data-sharing agreements. VPP aggregators report waiting months for meter data APIs that utilities promised were forthcoming, receiving data in formats that require expensive re-engineering, or simply being told that no formal access pathway exists.
The downstream effect is real: VPP programs get stunted, customer enrollment slows, and the utility's own demand response program — often more expensive and less effective — faces no competitive pressure to improve.
The Antitrust Angle Is Stronger Than It Sounds
Invoking antitrust law in an energy regulatory context sounds aggressive, even academic. But the legal theory here isn't exotic.
The essential facilities doctrine — a principle developed through U.S. antitrust case law — holds that when a monopolist controls infrastructure that competitors cannot practically replicate, and denies access to that infrastructure without legitimate justification, it may constitute illegal monopolization under Section 2 of the Sherman Act. The classic example is a railroad bridge. The modern example might be utility metering data.
Utilities are legal monopolies over distribution infrastructure, granted that status in exchange for regulatory oversight. They don't compete for meter infrastructure — they own it by law. If that infrastructure is essential to providing a competitive service (VPP aggregation), and the monopolist is using control over it to suppress competition in adjacent markets, the antitrust case becomes more than theoretical.
The groups calling for antitrust action are essentially arguing that regulated monopoly status doesn't grant immunity from competition law in markets where competition is supposed to exist. That's a critical distinction regulators have historically been reluctant to draw clearly.
Whether courts would agree is another matter. Antitrust litigation in regulated industries is notoriously complex — defendants routinely invoke the filed rate doctrine and the Noerr-Pennington doctrine to insulate regulated conduct from antitrust scrutiny. Utilities would argue they're simply complying with state data privacy rules or operating within the bounds of their tariffs. Those defenses have worked before.
But the legal threat doesn't need to result in a trial to be effective. The prospect of antitrust scrutiny changes utility behavior. It creates negotiating leverage. And it pressures state public utility commissions — which have largely avoided forcing utilities to open up meter data access — to act before litigation forces the issue.
What Would Actually Fix This
Antitrust law is a blunt instrument. It works slowly, costs money, and outcomes are uncertain. The faster path to virtual power plant access runs through state regulators and federal policy directives, not courtrooms — though sometimes the courtroom threat is what it takes to get regulators moving.
A few things would materially change the situation:
Standardized data access frameworks. California's Green Button Connect standard is a partial model — it enables customers to authorize third-party access to their meter data in a standardized format. But adoption is uneven, implementation quality varies, and utilities retain significant control over what gets shared and how quickly. Federal standardization, potentially through FERC or DOE rulemaking, would level the playing field nationally.
Utility unbundling of data services. Several European markets have moved toward treating meter data management as a separate, neutral function — not something operated by the distribution utility with a financial stake in limiting access. That structural separation removes the competitive conflict entirely. It's a long-run policy shift, but it's the cleanest solution.
Performance-based incentives. State regulators could tie utility earnings to VPP enrollment targets or third-party program participation metrics. Utilities respond to their revenue structure. If sharing meter data improves the rate case, they'll share meter data.
In the near term, the most actionable lever is probably FERC Order 2222, which already requires grid operators to allow distributed energy resource aggregations to participate in wholesale markets. The order exists. The question is whether utilities are creating the interconnection and data-sharing conditions that make participation viable — or whether they're complying with the letter while undermining the spirit.
The Trajectory
VPP adoption is accelerating despite these barriers. OhmConnect, AutoGrid, Swell Energy, and a handful of other aggregators have demonstrated real programs at meaningful scale. Utilities themselves — facing grid reliability pressure and clean energy mandates — are launching their own VPP programs, which creates an odd dynamic: the entities allegedly blocking VPP market access are simultaneously marketing VPPs to their own regulators as grid modernization achievements.
That contradiction is actually useful. It means utilities can't argue VPPs don't work or aren't valuable. The debate has shifted from "are VPPs real" to "who controls them" — and that's a fight worth having.
The groups pushing antitrust action may or may not prevail in court. But by naming the problem precisely — meter data access as a chokepoint, utilities as both monopolist and competitor, antitrust law as a potential remedy — they've put utilities and their regulators on notice that the status quo has a legal expiration date.
Grid operators need dispatchable flexibility. The assets to provide it already exist in homes and businesses across the country. The only thing standing between those assets and the grid is a data pipeline that utilities control and, according to these groups, are choosing not to share. That's not a technical problem. It's a market power problem — and it should be treated like one.
