Shapiro PJM Backstop Costs and Pennsylvania Data Centers

What Shapiro ordered in August 2026

Pennsylvania Gov. Josh Shapiro issued an executive order directing the Pennsylvania Public Utility Commission to develop rules limiting reliability impacts from data centers [canary-shapiro-eo-2026]. The order codifies standards Shapiro floated in February 2026.

Core requirements for data centers above 25 MW seeking preferential permitting include:

• Secure incremental electric capacity for their full demand, or face curtailment before other customers during emergencies [canary-shapiro-eo-2026]
• Pay grid upgrade costs tied to their service [canary-shapiro-eo-2026]
• Meet rising carbon-free power percentages (10% in 2027 scaling to 32% by 2035) if they sign DEP consent orders [canary-shapiro-eo-2026]

PUC Chair Stephen DeFrank backed the plan, saying Pennsylvanians should not subsidize infrastructure for the world's largest energy users [canary-shapiro-eo-2026].

PJM's 6.8 GW shortfall and backstop auction

PJM's July 2026 proposal addresses data-center-driven load growth by pushing states to decide who pays for emergency capacity [canary-shapiro-eo-2026]. PJM faces an estimated 6.8 GW shortfall in coming years, triggering a proposed reliability backstop auction [canary-shapiro-eo-2026] [pjm-board-letter-2026].

Shapiro's order tells the PUC to ensure utilities charge data centers, not other customers, for backstop costs assigned to them, even if a data center becomes insolvent [canary-shapiro-eo-2026].

For a cannabis cultivator, two channels matter:

1. Existing PJM capacity charges already embedded in default supply and many retail contracts
2. Future backstop charges if procurement proceeds and state rules assign them

Neither channel reduces PPL or PECO delivery demand charges.

Why grows still care about data center policy

Cannabis facilities are large C&I loads, but they are not typically 25 MW hyperscale data centers. Policy still affects growers because:

• Capacity market forecasts include all new load until segmented
• Transmission upgrades are regionally shared until allocated
• Retail contract pass-throughs may reference PJM regulatory charges broadly

Central PA operators shopping supply around PPL's 12.745¢ June 2026 benchmark should read our PPL price-to-compare post alongside this policy tracker.

Topic	Cultivator action
Default supply	Track June/December PTC resets
Retail fixed contract	Read PJM capacity pass-through table
Delivery bill	Monitor transmission riders separately
Policy	Watch PUC rulemaking on backstop allocation

Worked example: capacity pass-through sensitivity

Assume a retail contract passes through PJM capacity at actual cost. Inputs we chose.

Input	Value
Monthly kWh	85,000
Embedded capacity in default	2.1¢/kWh (illustrative)
Default supply @ 12.745¢ PTC	$10,833/month supply [from PPL context]
Pass-through adds 0.4¢ if backstop fills	85,000 × $0.004 = +$340/month

This illustration is not a published backstop rate; it shows why pass-through language matters when policymakers move costs between customer classes [canary-shapiro-eo-2026].

Fixed all-in contracts may delay pain until renewal. See fixed vs index contracts.

Alignment with PJM's July proposal

Shapiro's curtailment and bring-your-own-power rules mirror PJM's plan to have state-regulated utilities decide which data centers face interruption unless they self-supply capacity [canary-shapiro-eo-2026]. Illinois ComEd proposed an interruptible data center tariff in the same vein [canary-shapiro-eo-2026].

Maryland cultivators seeing transmission spikes should read Maryland OPC on PJM transmission costs for the delivery-side parallel.

Practical steps for PA operators

1. Under Pennsylvania switching, compare retail offers with explicit PJM capacity tables.
2. Model default supply using Pennsylvania commercial rates as context, not as a substitute for your bill.
3. Monitor PUC rulemaking implementing Shapiro's order for backstop cost assignment language.
4. Keep demand management (staggered lights, HVAC sequencing) focused on utility delivery tariffs you cannot shop away.

Policy may shift who pays for the next increment of PJM procurement [canary-shapiro-eo-2026]. It does not remove capacity charges from the market. Cultivators should contract with eyes open on pass-throughs and reset dates, not assume data center rules automatically lower grow supply rates overnight.

Consent order path vs business-as-usual siting

Shapiro's order offers preferential permitting for data centers signing DEP consent orders with bring-your-own-power commitments [canary-shapiro-eo-2026]. Facilities that skip consent face longer reviews and potential local opposition [canary-shapiro-eo-2026].

Cannabis facilities operate under separate state licensing but share PJM capacity math with any new large load. Local zoning hearings increasingly reference grid cost allocation language from data center debates.

Carbon-free percentage schedule

Consent-order data centers must hit 10% carbon-free power in 2027, rising to 32% by 2035 [canary-shapiro-eo-2026]. Cultivators buying 100% renewable retail supply for branding should verify RPS vs voluntary REC claims separately from this data center policy.

Massachusetts 100% renewable waiver rules for lighting limits differ; see REC guidance if you operate multi-state.

Sierra Club diesel backup concern

Separate legislation would limit diesel generators data centers use during curtailment events [canary-shapiro-eo-2026]. Cultivators with backup gensets for crop protection should not assume diesel policy tracks data centers exactly, but air quality enforcement trends are worth monitoring with counsel.

Practical contract clause search

Search retail supply PDFs for:

• Regulatory change in law
• Material adverse change in ISO rules
• Capacity pass-through definitions referencing RPM or backstop

If a clause allows unilateral supplier adjustment, model worst-case adders before signing through 2028 PJM capacity cycles discussed in industry reporting [canary-shapiro-eo-2026].

Data Center Coalition response

The Data Center Coalition supported Shapiro's order framework while warning against midstream rule changes for projects already underway [canary-shapiro-eo-2026]. Cannabis operators are not coalition members, but retroactive regulatory risk language in supply contracts should be read in the same spirit.

The 25 MW threshold and why cultivators sit below it

Shapiro's order targets data centers above 25 MW seeking preferential permitting [canary-shapiro-eo-2026]. A 500 kW cannabis flower room is large by horticulture standards but an order of magnitude below the 25 MW line. You will not receive data-center minimum charges or curtailment-first treatment under this order.

You still pay PJM capacity embedded in PPL, PECO, and Duquesne default supply because capacity markets price regional margin, not individual customer class [canary-shapiro-eo-2026]. Policy that shifts backstop auction costs to data centers may eventually lower capacity forecasts for everyone else, but timing is uncertain. Contract for pass-through transparency now rather than assuming future political wins.

PJM board letter and the 6.8 GW shortfall timeline

PJM's May 2026 board letter to governors described a 6.8 GW shortfall in accredited resources relative to load forecasts, triggering discussion of a reliability backstop auction [pjm-board-letter-2026]. The letter asked states to decide cost allocation before emergency procurement proceeds [canary-shapiro-eo-2026].

Pennsylvania cultivators should read the letter's appendix tables with counsel if your retail contract includes regulatory change in law clauses. A backstop charge assigned to data centers only under Shapiro's PUC rules may not appear on your bill; a broad RTO allocation would [canary-shapiro-eo-2026] [pjm-board-letter-2026].

PECO quarterly resets versus PPL semiannual calendars

Pennsylvania utilities reset default supply on different calendars as described in our PPL June 2026 price-to-compare post. PECO moves quarterly; PPL moves June 1 and December 1. Philadelphia-area grows and Central PA grows therefore hit capacity-driven supply changes on different months even when PJM capacity is identical [canary-shapiro-eo-2026].

MSOs should maintain a procurement calendar by meter, not by state. Compare Pennsylvania commercial electricity rates for context and Pennsylvania switching steps for enrollment mechanics.

Carbon-free percentage schedule for consent-order data centers

Consent-order data centers must hit 10% carbon-free power in 2027, rising to 32% by 2035 [canary-shapiro-eo-2026]. Cultivators buying 100% renewable retail supply for branding should verify RPS versus voluntary REC claims separately from this data center policy. See renewable energy certificates for cannabis brands.

Contract clause search before 2028 capacity cycles

Search retail supply PDFs for regulatory change in law, material adverse change in ISO rules, and capacity pass-through definitions referencing RPM or backstop [canary-shapiro-eo-2026] [pjm-board-letter-2026]. Clauses allowing unilateral supplier adjustment require worst-case adder modeling before signing through 2028 PJM capacity cycles discussed in industry reporting [canary-shapiro-eo-2026].

Diesel backup and air quality trends

Separate legislation would limit diesel generators data centers use during curtailment events [canary-shapiro-eo-2026]. Cultivators with backup gensets for crop protection should confirm air quality rules with counsel; diesel policy may not track data centers exactly but enforcement trends matter for outage planning [canary-shapiro-eo-2026].

Data Center Coalition retroactive risk framing

The Data Center Coalition supported Shapiro's framework while warning against midstream rule changes for projects already underway [canary-shapiro-eo-2026]. Cannabis operators are not coalition members, but retroactive regulatory risk language in supply contracts should be read in the same spirit before 2027 PUC rules publish [canary-shapiro-eo-2026] [pjm-board-letter-2026].

Local zoning and grid cost allocation hearings

Cannabis facilities operate under separate state licensing but share PJM capacity math with any new large load [canary-shapiro-eo-2026]. Local zoning hearings increasingly reference grid cost allocation language from data center debates; engage early if expanding MW-scale processing [canary-shapiro-eo-2026].

Practical steps for PA operators this quarter

1. Under Pennsylvania switching, compare retail offers with explicit PJM capacity tables [canary-shapiro-eo-2026]
2. Model default supply using Pennsylvania commercial rates as context, not as a substitute for your bill [canary-shapiro-eo-2026]
3. Monitor PUC rulemaking implementing Shapiro's order for backstop cost assignment text [pjm-board-letter-2026]
4. Keep demand management focused on utility delivery tariffs you cannot shop away [canary-shapiro-eo-2026]

Policy may shift who pays for the next increment of PJM procurement [canary-shapiro-eo-2026]. Cultivators should contract with pass-through eyes open, not assume data center rules automatically lower grow supply rates overnight [pjm-board-letter-2026].
