# Regulators as referees: how policy decisions reshape the competitive field
On April 1, 2022, Ofgem (the UK's Office of Gas and Electricity Markets) tightened the mechanics of its household energy price cap. Within months, more than two dozen UK energy suppliers had collapsed or been forced into takeovers, including household names like Bulb Energy. A regulatory formula update, adjusting how often the cap could reset to reflect wholesale costs, helped determine which companies survived a price shock and which didn't. That is what a referee does: not play the game, but decide the rules that determine who wins it.

Energy is a heavily regulated sector because it involves natural monopolies (you don't build six competing electricity grids down one street), public safety, and universal service obligations. That means regulators control things that are pure market-share weapons elsewhere:
Because of this, a single ruling can transfer billions in value between players overnight, without a single customer switching providers or a single new plant being built.
The UK price cap, introduced in 2019, limits what suppliers can charge default-tariff customers. It was designed to protect consumers from being overcharged for staying on "loyalty" tariffs.
The problem: the cap update lagged real wholesale gas and electricity prices. When wholesale prices spiked in 2021 to 2022 (partly due to the aftermath of COVID demand swings and then the energy crisis following Russia's invasion of Ukraine), many small suppliers were locked into selling energy below cost.

Winners: large, vertically integrated incumbents like Centrica (British Gas) and EDF, who had hedging capacity and balance sheets to ride out the mismatch, and who absorbed the customer books of failed rivals, often at attractive prices, sometimes with government support.
Losers: the challenger cohort that had used the price cap era to disrupt on price. Ofgem later reformed the cap's adjustment frequency and added mechanisms for suppliers to recover certain costs, an implicit admission the rules had reshaped, not just refereed, the market. Details are public via Ofgem's price cap explainer.
The lesson: a regulator meant to protect consumers ended up consolidating the market into fewer, larger hands. Consumer protection and market structure are not separate questions.
In the US, the Federal Energy Regulatory Commission (FERC) regulates wholesale electricity markets and interstate transmission. In 2020, it issued Order 2222, requiring regional grid operators (like PJM Interconnection, the grid operator covering the Mid-Atlantic and parts of the Midwest) to let "distributed energy resources" (DERs), rooftop solar, batteries, EV chargers, demand-response contracts, aggregated together, bid directly into wholesale markets.
Before Order 2222, only large power plants and utility-scale assets could sell into these markets. DERs were locked out, effectively subordinate to the incumbent generation fleet.
This one order created a new competitive category: DER aggregators. Companies like Tesla (via its energy division), Sunrun, and specialist aggregators such as Enel X and AutoGrid suddenly had a legal pathway to compete with gas peaker plants and utility-owned batteries for the same revenue: keeping the grid balanced.
Winners: aggregators and behind-the-meter technology providers, who gained a genuinely new revenue stream, and consumers with solar-plus-storage, who can now monetize flexibility.
Losers, or at least the newly pressured: incumbent generators whose peaking plants were the default answer to grid stress, and utilities whose distribution monopoly logic assumed one-directional power flow.
Implementation has been slow and uneven across US regional grids (a good primer is FERC's own Order 2222 fact sheet), which is itself a lesson: regulatory intent and regulatory impact can be years apart, and the gap is where lobbying happens.
Three recurring levers regulators pull, each reshaping competitive position:
1. Price controls. Caps or floors decide who can profit and by how much. A cap set too low for wholesale volatility punishes thin-margin challengers first (Ofgem case). A price floor for capacity payments can protect incumbent generators from newer, cheaper entrants.
2. Market access rules. Deciding who is allowed to participate (FERC Order 2222) determines whether new business models can even exist. Access rules are often more consequential than price rules, because they define the competitive roster before any competition starts.
3. Allowed returns for monopolies. Regulators set the rate of returnrate of returnReturn on Investment: the ratio of net profit to the cost of an investment.

In the UK this is done through Ofgem's RIIO framework (Revenue = Incentives + Innovation + Outputs); in the US, state public utility commissions set allowed rates of return for utilities like Con Edison or Pacific Gas & Electric. Small changes in the allowed percentage compound into large sums given how capital-intensive grid infrastructure is.

It's tempting to think of regulators as outside the competitive game. In practice, regulators respond to political pressure, industry lobbying, and public opinion, and their decisions are shaped by who has the resources to participate in consultations, provide technical evidence, and litigate outcomes. Large incumbents typically have permanent regulatory affairs teams; small challengers often do not. This asymmetry means the referee's decisions are rarely made on a level playing field of input, even when the outcome is meant to be neutral.
