NextEra Energy plans to acquire Dominion Energy in a deal that would create the largest electricity producer in the United States, according to NPR. The combined entity would serve customers across a vast swath of the American southeast and eastern seaboard, from Florida through Virginia and into the Carolinas. NextEra, already the world’s largest producer of wind and solar energy, would absorb Dominion’s large nuclear and natural gas fleet along with its transmission infrastructure and regulated utility base. The deal raises immediate questions about affordability for residential and commercial customers, questions that NPR’s coverage identifies as the central public-interest concern. It also raises questions that go beyond household electric bills — about the concentration of critical infrastructure, the structure of American energy regulation, and whether the progressive push for rapid grid transformation has inadvertently laid the groundwork for exactly the kind of corporate gigantism that the left has historically opposed.
The received wisdom
The case for this merger, as utilities and their advocates will frame it, rests on several planks. Scale, the argument goes, enables investment: a larger combined entity can finance the grid upgrades, battery storage, and renewable buildout that the energy transition requires more efficiently than two separate companies pursuing overlapping goals. The capital costs of modernising an ageing electrical grid are enormous — estimates for the full US grid upgrade run into the trillions — and scale lowers the cost of capital. There are also operational arguments: a larger, more interconnected grid is more resilient to localised disruptions, can balance supply and demand across wider geographies, and can integrate intermittent renewable sources more smoothly.
From the progressive perspective on energy, there is even an ideological affinity with the merger. NextEra is explicitly committed to the energy transition; it is the world’s largest wind and solar producer and has staked its corporate identity on decarbonisation. Absorbing Dominion’s more fossil-fuel-heavy portfolio gives NextEra the opportunity — in theory — to accelerate the retirement of older coal and gas plants and replace them with renewables. Environmental advocates might therefore view the deal with cautious approval, provided adequate regulatory conditions are attached.
The mainstream energy analyst community will also note that utility mergers are not unusual, have been managed by regulators before, and that the relevant state and federal agencies — FERC, state public utility commissions — have the statutory tools to impose conditions, including rate caps, divestiture requirements, and service-quality benchmarks.
A different read
All of this is true, and the regulatory apparatus exists for good reason. But there is a deeper structural concern that deserves more attention than the merger discourse typically generates. The American electricity market is already one of the most concentrated and least competitive of any major developed economy’s utility sector. Unlike telecommunications or banking — sectors where at least the aspiration of competition has driven policy — electricity distribution is almost universally a regulated monopoly. The justification is that wires and transmission infrastructure are natural monopolies: it makes no economic sense to run parallel distribution networks to the same set of homes. The regulator, in theory, substitutes for market competition by setting rates and imposing service standards.
The theory depends on the regulator having sufficient information, political independence, and legal authority to enforce consumer protections against a company whose size and political connections have grown well beyond those of the regulator. As NPR notes, the central concern is affordability. In state after state where utility mergers have been approved, rate increases have followed. The empirical record on utility consolidation and consumer prices is mixed at best: a 2019 study published in the Journal of Regulatory Economics found that mergers among investor-owned utilities produced mixed outcomes for customers, with benefits accruing primarily to shareholders.
There is also a less-discussed political economy dimension. NextEra is the world’s largest renewable energy company and a significant political actor in states where it operates. Its business model depends critically on regulatory decisions about renewable energy mandates, subsidies, tax credits, and grid interconnection rules — decisions made by the same state utility commissions that will review this merger, and by the same federal government that has spent the last several years massively expanding clean energy subsidies. A combined NextEra-Dominion would be a genuinely enormous regulated entity with enormous political interests. That combination — regulatory dependency plus political scale — is a recipe for the kind of regulatory capture that economists have documented in utilities, telecoms, and finance going back to George Stigler’s foundational work in the 1970s.
The conservatives who have historically worried most about corporate concentration have often been the same people most sceptical of energy mandates and grid transformation timelines. There is an irony, worth noting without gloating, in the fact that the progressive energy agenda — aggressive renewable mandates, forced grid modernisation, subsidies for specific technologies — creates the conditions for exactly the kind of mega-utility consolidation that concentrates power in fewer hands. The green transition and corporate gigantism are not inherently linked, but the policy environment the left has built makes the latter more likely, not less.
What to watch
The first test is the Federal Energy Regulatory Commission (FERC) review, which will examine market concentration and transmission access. Watch whether FERC imposes meaningful structural conditions — rate freezes, divestiture of transmission assets, open-access mandates — or approves the deal with cosmetic conditions. State utility commissions in Virginia, Florida, and the Carolinas are the second layer of scrutiny; their political composition will matter enormously. Watch also for Congressional interest: both progressive Democrats concerned about corporate concentration and conservative Republicans concerned about energy costs have incentives to scrutinise this deal. Finally, watch the bond market: if the merged entity’s credit rating improves materially, the financial benefits of consolidation are landing with shareholders; if customer rate requests follow within 18 months, the affordability concern will have been validated.
