PJM's $100 Billion Rate Shock: How Data Centers Are Rewriting America's Electricity Bills

Feb 28, 2026 Written By Blake Crosley

PJM Interconnection's capacity auction cleared at $329.17 per megawatt-day for the 2026-2027 delivery year, a price that would have seemed fictional two years earlier.¹ In the 2024-2025 auction, generators accepted $28.92/MW-day to keep the lights on for 67 million people across 13 states and Washington, D.C.² The roughly tenfold increase landed squarely on ratepayers, and data center demand drove 63% of it.³ Cumulative costs through 2033 could reach $100 billion to $163 billion, depending on whether price caps hold.⁴⁵ The average family in PJM territory faces an estimated $70-per-month increase by 2028.⁶ State legislators from Virginia to Oregon have responded with a wave of rate reforms, tax incentive rollbacks, and construction moratoriums that will reshape data center economics for at least the next decade.

TL;DR

PJM capacity prices surged from $28.92/MW-day (2024-2025) to $329.17/MW-day (2026-2027), hitting the FERC-approved price cap for two consecutive auctions. Data centers caused 63% of the price increase in the 2025-2026 auction, adding $9.3 billion in capacity costs that all ratepayers must absorb. NRDC estimates $100 billion to $163 billion in cumulative costs through 2033 unless regulators intervene. Oregon became the first state to create a dedicated data center rate class. Virginia's SB 253 would shift distribution and capacity costs from households to data centers. At least six states have introduced construction moratoriums, and seven states have moved to repeal or restrict data center tax incentives worth billions annually.

The PJM Price Explosion: A Three-Year Timeline

PJM Interconnection operates the largest wholesale electricity market in North America, coordinating power delivery for 65 million customers across Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and the District of Columbia.⁷

The capacity market ensures generators remain available to meet future demand. Utilities purchase capacity credits through annual auctions, and those costs flow directly into household electricity bills. The last three auctions tell a story of exponential cost escalation:

The 2025-2026 auction delivered the sharpest single-year increase in PJM's 27-year capacity market history: an 833% jump from $28.92 to $269.92/MW-day.¹¹ The 2026-2027 auction hit the FERC-approved price cap of $329.17/MW-day, and the December 2025 auction for 2027-2028 hit the updated cap of $333.44/MW-day while falling 6,625 MW short of reliability requirements for the first time ever.¹²¹³

PJM's Independent Market Monitor calculated that the existing price cap already prevented $13 billion in additional capacity costs from reaching ratepayers.¹⁴ Without the cap, clearing prices could have exceeded $500/MW-day.¹⁵

Who Pays and How Much

The cost transmission mechanism from capacity auction to household bill involves no buffer. Utilities purchase capacity at auction, regulators approve cost recovery through rate cases, and customers absorb the full amount.¹⁶

Regional Cost Impact

The $9.3 billion in data center-driven capacity costs for the 2025-2026 delivery year spread unevenly across PJM's footprint.¹⁷ Data centers account for 40% of total PJM capacity costs in the most recent auction, and the Dominion Energy zone in Virginia faces capacity fees 65% higher than the rest of the grid.¹⁸¹⁹

Residential customers in western Maryland already pay approximately $18 more per month in PJM capacity costs.²⁰ Ohio residents pay roughly $16 more monthly.²¹ Across seven mid-Atlantic states, utilities assigned $4.3 billion in data center connection costs to ratepayers in 2024 alone.²²

The NRDC Projection

NRDC's analysis of PJM forecasts projects cumulative capacity costs of $163 billion from 2028 through 2033 if the temporary price cap expires as scheduled, translating to an annual capacity bill of $27 billion to $30 billion per year during that window.²³ Synapse Energy Economics produced a more conservative estimate of approximately $100 billion through 2033, assuming some form of price mitigation remains in place.²⁴ Both figures dwarf historical norms. Before the data center demand surge, PJM's annual capacity costs averaged roughly $8 billion to $10 billion.²⁵

Delaware's Division of the Public Advocate called the situation urgent enough to petition PJM on January 30 for an extension of the price cap beyond its current expiration.²⁶ PJM agreed on February 12 to seek an extension for the next two auction cycles.²⁷

The Supply-Demand Gap

The price explosion reflects a structural supply-demand imbalance that PJM's own forecasts show worsening through at least 2030:

PJM procured 134,479 MW of generation resources in the December 2025 auction against a 141,101 MW reliability requirement.³⁴ The 5.2% shortfall marked the first time in PJM's history that a capacity auction failed to meet the installed reserve margin target.³⁵

The State Legislative Response

Legislators across both parties have introduced more than 238 data center-related bills in all 50 states during 2025, enacting over 40 in 21 states.³⁶ The 2026 session has accelerated the pace. Three categories of legislation dominate: rate structure reform, tax incentive rollbacks, and construction moratoriums.

Rate Structure Reform: Making Data Centers Pay Their Share

Oregon's POWER Act (HB 3546)

Oregon became the first state to create a dedicated data center electricity rate class when the legislature passed the Protecting Oregonians With Energy Responsibility (POWER) Act with bipartisan support in June 2025.³⁷ The law applies to facilities consuming more than 20 MW and requires:

• 10-year minimum contracts committing large energy users to a baseline demand payment regardless of actual consumption³⁸
• Separate cost allocation so data center infrastructure investment does not subsidize residential rate increases³⁹
• Transmission cost pass-through requiring large users to pay for grid upgrades they trigger⁴⁰
• Biennial PUC reporting beginning September 1, 2026, reviewing load growth trends and ratepayer impacts⁴¹

Portland General Electric currently charges large industrial users approximately $0.08/kWh.⁴² The Oregon Public Utility Commission will determine the new data center rate, which analysts expect will exceed current industrial tariffs given the flat, 24/7 load profile data centers maintain.⁴³

Oregon's Citizens' Utility Board championed the legislation, framing the issue directly: data centers run at peak demand constantly, and existing rate structures never anticipated that load pattern at scale.⁴⁴

Virginia's SB 253

Virginia Senator L. Louise Lucas introduced an amendment to Senate Bill 253 that would shift distribution and PJM capacity auction costs from residential customers to data centers drawing 25 MW or more.⁴⁵ The State Corporation Commission estimated a 3.4% residential rate reduction (approximately $5.52/month savings) and a 15.8% data center rate increase.⁴⁶ Dominion Energy supports the bill.⁴⁷ (For a deep analysis of SB 253's mechanics and implications, see our full coverage: Virginia SB 253: The Bill That Could Reshape Data Center Economics Nationwide.)

Other State Rate Actions

At least a dozen states, led by both Republican and Democratic lawmakers, have targeted data centers with separate, higher electric rates or required long-term financial commitments before approving grid infrastructure investments for new facilities.⁴⁸

Oklahoma Republican state senator Brad Boles introduced a ratepayer protection bill requiring data center operators to cover their proportional share of infrastructure costs rather than socializing them across all customers.⁴⁹ Virginia regulators approved a new GS-5 rate class in November 2025 establishing 14-year mandatory contracts for data centers above 25 MW, with minimum demand charges at 85% of contracted capacity.⁵⁰

Tax Incentive Rollbacks: The $1.6 Billion Question

Thirty-seven states currently offer data center tax incentives.⁵¹ The original economic rationale assumed modest fiscal costs and substantial job creation. The actual numbers have diverged dramatically from projections.

State-by-State Tax Incentive Status

Virginia's tax incentive story stands out for the sheer gap between projection and reality. When the Commonwealth enacted data center sales and use tax exemptions in 2010, fiscal analysts estimated annual costs of approximately $1.5 million.⁶¹ By fiscal year 2025, actual foregone revenue reached $1.6 billion, a 118% increase over the prior year and a 106,000% overshoot of the original estimate.⁶² Bills HB 897, SB 393, and HB 784 propose new energy standards, additional taxes, and increased transparency, though observers expect the legislature to focus on disclosure requirements rather than outright repeal during the current session.⁶³

Georgia's exemptions jumped from $10 million in 2020 to $625 million in 2026.⁶⁴ The Georgia Senate passed a bill to suspend future data center tax exemptions, though Governor Brian Kemp vetoed a full repeal bill in 2024, citing business climate concerns.⁶⁵ Seven separate bills targeting data centers advanced in the 2026 Georgia session, covering tax repeal, residential ratepayer protections, and construction moratoriums.⁶⁶

Michigan's repeal effort bridged the political spectrum in ways that defied traditional coalitions. State Representatives Jim DeSana (R-Carleton) and Dylan Wegela (D-Garden City) co-sponsored a three-bill package to overturn sales and use tax exemptions that the legislature narrowly approved in late 2024.⁶⁷ No fewer than 19 Michigan communities imposed local moratoriums on data center development even before the state-level repeal effort began.⁶⁸

Construction Moratoriums: Hitting the Pause Button

Six states introduced data center construction moratoriums during the first two months of 2026, signaling a fundamental shift in how communities view large-scale compute infrastructure.⁶⁹

New York's proposal, introduced by State Senator Liz Krueger and Assembly member Anna Kelles on February 6, 2026, drew particular attention.⁷⁶ The bill (S.9144) would halt permits for new data centers exceeding 20 MW for three years while the Department of Environmental Conservation and Public Service Commission assess environmental impacts and recommend regulations.⁷⁷ Food & Water Watch described the measure as "the most robust data center moratorium bill introduced nationwide."⁷⁸

The bipartisan nature of these efforts underscores the depth of public frustration. Democrats sponsored bills in New York, Virginia, Georgia, and Vermont. Republicans led the charge in Maryland and Oklahoma.⁷⁹ The political calculus has shifted: elected officials now view data center cost-shifting as a liability with voters, not an economic development asset.

The NDA Transparency Movement

A parallel trend targets the secrecy surrounding data center development deals. Lawmakers in five states have proposed prohibiting governments from signing nondisclosure agreements with data center developers.⁸⁰ New Jersey emerged as an early mover on transparency, with bill S3379 (introduced February 9, 2026) requiring data center operators to submit semi-annual water and energy usage reports to the Board of Public Utilities.⁸¹

The NDA backlash stems from documented cases of communities approving projects without understanding their resource impacts. At least four Wisconsin communities signed secrecy agreements for billion-dollar data center projects, preventing public disclosure of energy consumption, water usage, and tax incentive terms before construction began.⁸²

The Industry Counterargument

Not every analysis supports the narrative that data centers uniformly raise costs. Amazon commissioned consulting firm E3 (Energy + Environmental Economics) to produce "Tailored for Scale: Designing Electric Rates and Tariffs for Large Loads," released in December 2025.⁸³ The study analyzed Amazon data centers in four utility territories (Pacific Gas & Electric, Umatilla Electric Cooperative, Dominion Energy, and Entergy) and concluded that the facilities evaluated generated surplus utility revenue rather than cost subsidies.⁸⁴

E3 projected $3.4 million in surplus revenue from a hypothetical 100 MW facility in 2025, growing to $6.1 million by 2030.⁸⁵ The study argued that regulators have "considerable latitude to design tariffs applicable to large loads in ways that provide revenue sufficiency, do not unduly discriminate, do not lead to excessive cost shifts, and promote broader state policy objectives."⁸⁶

A separate 2026 report by Charles River Associates for the Edison Electric Institute reached similar conclusions, finding that data centers "were generally not the cause of rate increases" in areas where prices rose.⁸⁷

Consumer advocates challenged both studies' methodologies. IEEFA's analysis attributed 63% of PJM's 2025-2026 price increase directly to data center load growth.⁸⁸ The Citizens Utility Board and NRDC jointly warned that PJM states face up to $163 billion in additional capacity costs and potential forced blackouts if demand growth continues outpacing supply.⁸⁹ Yale Climate Connections framed the disparity bluntly: "Home electricity bills are skyrocketing. For data centers, not so much."⁹⁰

The disconnect between facility-level economics and system-level impact sits at the heart of the policy debate. An individual data center may generate surplus revenue for its host utility while simultaneously driving region-wide capacity costs that dwarf that surplus by orders of magnitude.

What Comes Next: The 2026-2028 Regulatory Landscape

Several critical decisions will shape data center economics over the next 24 months:

PJM Price Cap Extension. PJM agreed on February 12, 2026, to seek FERC approval for extending the capacity price cap beyond its current two-auction window.⁹¹ Without the extension, clearing prices could exceed $500/MW-day, pushing annual capacity costs above $30 billion.⁹² FERC's decision will directly determine whether the $100 billion or $163 billion cost scenario materializes.

Oregon PUC Rate Determination. The Oregon Public Utility Commission will set the actual rate for the new data center classification created by the POWER Act.⁹³ PGE proposed a 25% increase with a "Peak Growth Modifier" for large-load customers.⁹⁴ The PUC's decision will establish a precedent other states watch closely.

Virginia Crossover Deadline. Virginia's legislative session faces a crossover deadline on February 18 and adjournment on March 14.⁹⁵ SB 253's fate, along with bills addressing tax incentive transparency and energy standards, will determine whether the nation's largest data center market enacts meaningful cost reallocation.

New York Moratorium Vote. If passed, S.9144 would create the most restrictive data center development environment in any major U.S. market, potentially redirecting billions in investment to other states.⁹⁶

FERC Colocation Policy. FERC's ongoing review of data center co-location at existing power plants will determine whether behind-the-meter arrangements can reduce capacity market pressure or simply shift costs differently.⁹⁷

Key Takeaways

For Infrastructure Planners

The era of cheap, no-strings-attached power for data centers has ended. Every major market in the PJM footprint now faces capacity prices at or near the FERC cap, and at least 12 states have introduced legislation creating separate rate classes, long-term contract requirements, or both. Site selection models must incorporate not only current electricity rates but projected regulatory trajectories across a 10-15 year horizon. Facilities built today in states with pending rate reform will operate under fundamentally different economics by the time they reach full capacity.

For Operations Teams

Organizations like Introl, with 550 HPC-specialized field engineers across 257 global locations, understand the operational implications of these shifts. When capacity costs rise 10x and regulators mandate separate rate classes, operational efficiency stops being an optimization exercise and becomes a survival requirement. Power usage effectiveness, demand response participation, and load management directly impact whether a facility remains economically viable under new rate structures. The 100,000-GPU deployment capability Introl maintains reflects the scale at which these cost pressures compound.

For Strategic Decision-Makers

The regulatory landscape has bifurcated. States like Texas (ERCOT market, no capacity auction) and states with nuclear co-location pathways offer different cost profiles than PJM territory. However, moratorium proposals in New York, Oklahoma, and Georgia demonstrate that even non-PJM markets face political risk. The winning strategy involves diversified geography, long-term power procurement (PPAs, behind-the-meter generation), and proactive engagement with rate design proceedings before they produce unfavorable outcomes. Waiting for the regulatory dust to settle means accepting whatever rate structures emerge from processes driven by consumer advocates and ratepayer frustration.
