PJM Interconnection, a major regional transmission organization, has developed new guidelines aimed at regulating how cryptocurrency mining operations participate in wholesale electricity markets. These guidelines will be incorporated into PJM’s official rule manual through a stakeholder engagement process scheduled for 2026.

Background and Current Market Activity

The initiative addresses concerns about cryptocurrency mining facilities participating in PJM’s economic demand response programs within the energy market. According to Peter Langbein, PJM’s manager of demand side response operations, approximately 99 percent of all economic demand response activity in the energy market currently originates from cryptocurrency-type facilities. This participation generates between $1 million and $2 million monthly, representing roughly 65 megawatts per month with substantial settlement hours.

Langbein clarified that these guidelines specifically address economic demand response in the energy market and do not pertain to load management or capacity market participation. The distinction is important: economic demand response allows market participants to elect participation based on their economic circumstances, selecting when to curtail operations according to wholesale electricity price signals.

Primary Concerns Triggering the Guidelines

PJM has observed what it characterizes as “significant” curtailment activity that raised regulatory questions, particularly when mining equipment is older in age. The core concern involves cryptocurrency miners potentially extending the operational life of aging machines by curtailing their use rather than upgrading to newer equipment, while simultaneously collecting revenue from the wholesale power market through demand response participation.

Langbein noted that some facilities are curtailing operations nearly every day for multiple hours. Without the financial incentive provided by wholesale market revenue, these same operations would likely have already replaced their equipment with newer technology. This pattern suggests that facilities are deliberately maintaining uneconomic machines specifically to monetize curtailment activity rather than to optimize their primary business operations.

Key Guideline Changes

The primary change restricts participation of older cryptocurrency mining equipment. Curtailment service providers are now prohibited from participating in the energy market with cryptocurrency mining machines that are older than five years from their manufacture date, unless PJM explicitly approves an exception.

Additionally, regarding settlement procedures, curtailment service providers seeking PJM energy market payments must submit settlement claims only for hours when the hourly cost to mine cryptocurrency is lower than the hourly mining revenue. This requirement ensures that curtailment activity reflects genuine economic decisions rather than artificial market participation.

Regulatory Philosophy and Stakeholder Response

Langbein emphasized that the distinction between cryptocurrency miners and traditional electricity generators is fundamental to PJM’s regulatory approach. While generators operate to produce and sell electricity, cryptocurrency miners operate to mine digital currency. The regulatory position holds that cryptocurrency miners should not participate in electricity markets primarily to extend the life of aging equipment through curtailment revenue.

He noted that some operations have curtailed during 90 percent of hours across multiple-month periods, indicating that curtailment is not incidental to normal operations but rather a primary profit strategy.

One stakeholder challenged this position, arguing that cryptocurrency miners should retain the freedom to maintain their equipment through whatever economic strategy they choose, even if equipment is uneconomic relative to newer alternatives. This stakeholder drew a comparison to a natural gas-fired combustion turbine operator with a 50-year equipment lifespan who might curtail operations more frequently to extend asset life.

Langbein responded by restating the operational distinction: traditional power generators’ primary business function is electricity generation, whereas cryptocurrency miners’ primary business function is digital currency mining. Market participation should align with operational intent rather than serve as an alternative revenue stream for sustaining aged equipment.

Implementation Timeline

PJM plans to conduct comprehensive stakeholder engagement processes throughout 2026 to refine these guidelines further and integrate them officially into the grid operator’s rule manual. This approach allows for industry feedback before formal implementation.

These guidelines represent PJM’s effort to ensure that economic demand response participation genuinely reflects market participants’ operational economics rather than serving as an ancillary revenue mechanism for maintaining equipment that would otherwise be retired.

PJM Imposes Age Cap on Crypto-Mining Gear to Curb Market Gaming in Demand-Response Program

PJM Interconnection, the regional transmission organization that manages the electricity grid for 65 million people in the Mid-Atlantic and Midwest, has issued new guidelines that bar cryptocurrency miners from collecting wholesale power-market payments with machines more than five years old. The operator argues this step is needed to keep its demand-response program from becoming a subsidy for obsolete equipment, according to a December 10 notice posted via Reuters.

The policy, unveiled ahead of a formal stakeholder process slated for 2026, responds to a surge of curtailment bids by crypto facilities that switch off rigs when power prices spike and then collect payments for reducing load. PJM officials say nearly all—about 99 percent—of economic demand-response activity in its energy market now comes from such miners, generating between $1 million and $2 million in payouts every month.

By tightening eligibility, the grid operator hopes to ensure that demand response reflects genuine economic trade-offs rather than an opportunity for miners to prolong the life of outdated machines while cashing in on power-market incentives. The curtailment program was designed to let large users shed load during high-price hours, not to underwrite hardware that would otherwise be retired, PJM argues.

Early in December, PJM posted the guideline language to its rules manual and told members that curtailment service providers cannot submit crypto-mining equipment older than five years unless the operator grants an explicit waiver. Providers must also certify that, in any hour they seek payment, the cost to mine digital currency with the remaining rigs exceeds the revenue those rigs would have earned—effectively proving that curtailment is the economically rational choice.

“These changes target economic demand response only,” Peter Langbein, PJM’s manager of demand-side response operations, told stakeholders in a recent briefing. “They do not apply to load-management or the capacity market. We’re focused on behavior that looks like using the wholesale market as a supplemental revenue stream rather than as an operational tool.”

Primary Concerns and Data

PJM’s monitoring team began scrutinizing curtailment patterns after noticing that some facilities were turning off nearly every day for several hours. By Langbein’s count, one subset curtailed in roughly 90 percent of all hours over multiple months, a frequency he called “significant.” The scale is modest in megawatts—about 65 MW of average monthly participation—but large in settlement hours, translating into seven-figure monthly payouts.

The operator concluded that miners were in effect earning more from not running than from hashing. Without those payments, the older rigs—often less energy-efficient than newer models—would likely have been decommissioned or replaced. Instead, the market rules were inadvertently encouraging facilities to keep uneconomic gear plugged in, ready to be switched off for a check.

Rule Details

• Age cap: ASICs or other mining machines manufactured more than five years earlier are ineligible for economic demand response unless PJM grants an exception.

• Cost-revenue test: Curtailment service providers must file settlement claims only for hours when the variable cost of mining exceeds the expected crypto revenue, documenting the comparison.

• Scope: The guideline addresses PJM’s energy market; it does not change participation rules for the capacity market or traditional load-management programs.

• Timeline: Draft text is posted now, and PJM will run a full stakeholder process in 2026 before final integration into its rule manual.

Stakeholder Debate

During a member session, one participant questioned why a miner should be forced to upgrade rigs any more than a 50-year-old natural-gas turbine owner must upgrade to a newer unit. Langbein replied that the analogy misses a key distinction: a generator’s core business is producing electricity wholesale, whereas a miner’s core business is producing digital currency. “The market should not pay a facility to do the opposite of its primary purpose just to prolong the life of depreciated assets,” he said.

Another member asked whether PJM might extend similar guidelines to other large flexible loads, such as data centers that contemplate demand-response bids. Langbein indicated the operator is open to broader discussions but wants to solve the crypto issue first because the scale of participation is already material.

Settlement Mechanics

Under the cost-revenue test, a curtailment provider must compare the marginal power cost of running rigs to the expected crypto payout for each hour. If mining would have been profitable, the provider cannot claim a curtailment credit; if mining would have lost money, the claim is allowed. PJM’s market-settlement team will audit submissions periodically, and inaccurate attestations could trigger clawbacks or market-rule violations.

Industry Context

The crypto-mining sector has clustered in regions with cheap electricity, and miners in competitive power markets such as ERCOT in Texas have already turned demand response into a significant revenue stream. PJM’s intervention signals that other grid operators may revisit their own rules if they fear miners are gaming incentives designed for industrial loads, not financial arbitrage.

PJM’s footprint includes 13 states and the District of Columbia, making it the largest organized power market by peak load. While the number of megawatts tied to crypto mining is still small relative to total demand, the operator worries that unchecked growth could exacerbate reliability and price-formation challenges, especially during summer or winter peaks.

Implementation Path

Over the next year, PJM will circulate draft manual language, collect comments, and present revisions to its Market Implementation Committee. Final approval would come from the PJM Board of Managers, after which the rules would enter force. The operator has not said whether existing participants with older gear will receive a grace period or have to exit immediately.

Analysis and Outlook

Market analysts note that PJM’s move is the latest example of regulators grappling with how to incorporate flexible, non-traditional loads into power markets. Demand response can enhance reliability by reducing peak demand, but if the financial signals reward uneconomic behavior, overall system costs rise. By focusing on the age and efficiency of equipment, PJM hopes to align incentives with true system benefits rather than subsidize inefficiency.

For miners, the guideline may accelerate capital spending on newer, more efficient rigs capable of remaining profitable without leaning on curtailment payments. Some may relocate to regions with looser rules or vertically integrate with renewable generation to hedge power costs. Others could pivot toward ancillary service markets, provided they meet technical requirements.

The broader lesson for energy markets is that technology-neutral rules can have technology-specific consequences. When the price of bitcoin falls or power prices soar, miners rapidly shift from load to resource, complicating grid operations. PJM’s age-cap approach treats the symptom—outdated machines exploiting demand response—without banning mining outright. Whether that balance holds will depend on enforcement rigor and the willingness of miners to adapt.

Regulators across North America will watch the outcome closely. If PJM’s curbs prove effective at limiting gaming while preserving genuine flexibility, similar standards could emerge elsewhere. Conversely, if miners simply find new loopholes, policymakers may pursue stricter limits on crypto’s participation in electricity markets.
