PJM faces grid policy deadlock as AI data centres fuel rising electricity costs

Despite a heated debate over managing surging demand from AI-driven data centres, PJM Interconnection remains without a consensus, risking higher power prices and grid reliability in the US’s largest power market.

Members of PJM Interconnection, the largest power grid operator in the United States, have reached an impasse over how to manage the rapidly surging electricity demand generated by AI-driven data centers. Despite months of intense deliberations culminating in an advisory vote, a key step in PJM’s expedited regulatory process known as the Critical Issue Fast Path (CIFP), no consensus emerged among the diverse stakeholders. The vote, which sought endorsement of a dozen proposed measures ranging from requiring data centers to generate their own power, expediting energy project connections, to temporarily halting new data center hookups, failed to meet the necessary two-thirds approval threshold. This lack of agreement now leaves PJM’s 10-member board of managers with significant discretion to formulate its own policy approach addressing the challenge of serving expected demand of up to 30 gigawatts by 2030, an amount roughly equivalent to powering 20 million homes.

The consequences of this unresolved grid challenge are already starkly visible. Electricity prices across PJM’s extensive service territory, which includes all or parts of 13 states and the District of Columbia, have surged, driven heavily by data center consumption. One notable illustration occurred in New Jersey, where prices jumped 20% during a recent summer period, becoming a hot-button political issue. This price rise has stirred voter discontent in the state, with polling indicating bipartisan support for requiring data centers to bear a greater share of grid costs rather than ordinary households subsidising the technology giants benefiting from the power. As industry representatives debated the proposals, several voiced concerns about the implications of tough regulatory measures, including potential caps on energy company revenues or increased business risks that might ultimately be passed on to consumers.

This trend of rising prices is evident in PJM’s recent capacity auctions, which secure commitments from power producers to have generating capacity available during times of peak demand. The latest auction set a record-high price of $329.17 per megawatt-day, a staggering 1,000% increase compared to two years earlier, signalling immense pressure on both supply and consumers. Market analysts warn that electricity bills could rise by 30% to 60% by 2030 if current demand trajectories persist. While nearly 2,670 megawatts of new capacity were cleared in these auctions, this only satisfies half of the expected increase in demand, leaving a supply gap that threatens both affordability and grid reliability.

The energy mix underpinning PJM’s supply remains dominated by traditional sources: 45% natural gas, 22% coal, 21% nuclear, supplemented by minimal contributions from hydro, wind, and solar power. Although the region has approved over 46,000 megawatts of renewable projects, many remain in stalled construction phases, exacerbating concerns about delays in integrating clean energy. PJM has initiated a fast-track system to accelerate new power plant development, which attracted 50 candidate projects assessed for readiness and capacity. However, this process has attracted criticism from clean energy advocates who argue it disproportionately favours natural gas plants despite the abundance of renewable projects awaiting approval, and they question the transparency of the selection criteria.

One of the more stringent proposals on the table suggested halting new data center builds altogether until PJM can ensure reliable power delivery for current and future users. Others recommended incentivising data centers to self-generate power in return for prioritised grid connections and permitting, an idea supported by a coalition of four state governors along with major tech companies such as Google, Microsoft, and Amazon. Another legislative proposal advocates for demand response measures where data centers would need to reduce power usage during grid strain events, potentially firing up polluting diesel backup generators in emergencies, which raises environmental justice concerns.

Environmental groups urge PJM and regional stakeholders to consider rapid deployment of renewable energy to meet burgeoning demand sustainably. For example, advocates point to Texas’ progress in renewables as a model for accelerating clean energy integration. Climate policymakers stress the necessity of balancing the grid’s reliability with decarbonisation goals amidst the AI-driven expansion of energy-hungry data centres.

Now, PJM’s board is under pressure to devise a viable policy framework by December to present to the Federal Energy Regulatory Commission (FERC). Once submitted, FERC will evaluate the proposal’s fairness and potential discriminatory impacts. The board’s decisions will significantly shape the future of electricity pricing, infrastructure investment, and energy consumption governance across a vast swath of the eastern U.S., affecting millions of consumers and major tech industries alike.
