PJM / capacity market overhaul / NCBL
PJM Interconnection — the grid operator that serves 67 million customers across the mid-Atlantic (PA, NJ, MD, DC, VA, WV, OH, IN, IL, MI, KY, NC, TN), the largest electric market in the country — published a 27-page strategy paper on May 6 titled 'Powering Reliability Through Market Design' that proposes three frameworks for reforming the capacity market and creating a new category of customer called Non-Capacity-Backed Load (NCBL): large new loads ≥50 MW that opt out of the capacity-market obligation in exchange for being first-to-curtail during grid emergencies; the paper followed a January 16, 2026 PJM Board of Managers directive ordering a 'holistic review' of capacity market design after the July 2025 BRA auction cleared at $329.17/MW-day (a 9x increase over the prior year and the trigger for the four-state ratepayer-protection tariff cluster covered Saturday); CEO Manu Asthana said the paper opens a summer-2026 stakeholder process targeting a FERC filing later in 2026; the May 10 yournews / Daily Caller News Foundation pickup is the first general-press framing of the paper, characterizing it as a proposal to 'curtail electricity to newly connected data centers during peak demand periods' and contrasting NCBL load against residential and existing customer load — a political-economy framing that PJM does not technically endorse in the paper text but that anchors the public reading
PJM's 'Powering Reliability Through Market Design' paper is the most significant single regulatory-process document in the PJM footprint since FERC's December 18, 2025 order on co-located generation (which Cliff has been tracking via the pjm-er26-1088 page). The paper does not propose a single solution; instead, it lays out three alternative frameworks that the PJM Board of Managers says could maintain grid reliability through the 2027-2030 capacity gap that PJM forecasters now expect. Framework 1 preserves the historical 'one reliability standard for all customers' approach by requiring most new electricity demand to be covered by long-term forward commitments (i.e., 10-15-year PPAs with new generation), shielding consumers from price spikes but requiring data center developers to commit to specific generation projects before they can connect. Framework 2 introduces 'differential reliability' through the NCBL category: new large loads ≥50 MW choose among (a) 'NCBL with curtailment only,' which accepts roughly 98% reliability (vs. the 99.97% standard PJM has historically maintained, equivalent to no more than ~2-3 hours of outage per year), (b) 'NCBL with diesel backup,' where the developer pays for on-site emergency generation to cover the curtailment window, or (c) 'Bring Your Own Generation' (BYOG), where the developer pairs the new load with new gas, solar-plus-storage, or hybrid generation that comes online with the load, providing firm capacity that doesn't lean on the broader system. Critical infrastructure (hospitals, 911 centers, wastewater plants, gas stations, telecom facilities) is explicitly carved out. Framework 3 uses market-driven pricing with long-term contracting incentives and is the closest to the status quo. Per the Modo Energy analysis, PJM is operating through the Critical Issue Fast Path (CIFP) initiative — the same expedited process used for prior emergency tariff revisions — with a target FERC filing 'later in 2026' (Asthana did not commit to a specific date in his May 6 prepared remarks, but the public-comment cadence suggests Q3 or early Q4 2026). The political-economy framing in the press: the Daily Caller News Foundation / yournews May 10 piece — picked up over the weekend — explicitly contrasts 'newly connected data centers' against 'residential consumers and existing customers,' which is the political reading the paper enables even though Modo Energy's read of the actual document confirms no explicit residential-priority language. The paper's three frameworks all impose meaningful new obligations on hyperscaler data-center demand in the PJM footprint, which is the largest concentration of operating and announced AI data centers in the country (Loudoun County VA alone exceeds 25 GW of operating data center load).

Why it matters
Five updates layered. (1) PJM is now openly de-prioritizing data center reliability versus residential load, which is the single biggest structural change to data-center underwriting in the PJM footprint in 20 years. Historically, PJM has maintained one reliability standard — 99.97% — for every customer class, with the implicit promise that data centers got the same uptime as hospitals. The NCBL proposal explicitly breaks that promise. The technical reliability degradation is non-trivial: 98% uptime equals ~175 hours/year of curtailment risk, which is materially worse than even on-site diesel-backed generation (which typically targets 99.9%+ uptime). For an AI training cluster running a multi-month training run, 175 hours of unplanned curtailment in the middle of training is catastrophic — it doesn't just delay the run, it can void months of compute work depending on checkpoint frequency. This is not a number any AI hyperscaler can accept on a flagship training site, which means Framework 2 effectively forces every PJM-territory hyperscale developer into Framework 2(c) BYOG — bringing their own generation. Cliff's BTM-generation product surface (Layer 4 in the competitive-landscape map) is now structurally favored by the PJM proposal in a way it was not 30 days ago. Update strategy/competitive-landscape-and-adjacencies.md with a 'PJM NCBL favorable' tag on the BTM SKU. (2) The 50 MW NCBL threshold matches the four-state ratepayer-protection-tariff cluster (Pennsylvania PUC model tariff 50 MW individual / 100 MW aggregate; Florida SB 484 50 MW; PPL Electric 50 MW individual / 75 MW aggregate within 10-mile radius; Wisconsin We Energies 100 MW). The convergence at 50 MW across multiple PUCs AND the ISO suggests an emergent regulatory consensus that 50 MW is the threshold above which a new customer is treated as 'systemically significant' and therefore subject to different rules than commercial / industrial. This is exactly the kind of convergence that the regulatory-knowledge-graph product is built to capture — the per-utility-per-jurisdiction tariff lookup needs a 'systemically-significant-large-load threshold' field, and 50 MW is now the default value in nearly every PJM and PJM-adjacent jurisdiction. (3) The BYOG pathway in Framework 2(c) is a clean validation of Cliff's BTM-generation product wedge. PJM is now telling data center developers explicitly: if you want to interconnect in the PJM footprint and you're above 50 MW, your default option is to bring new generation that energizes with the load. That is the exact economic question the BTM SKU underwrites — gas turbine vs. CCHP vs. solar+battery+hybrid vs. SMR (when SMR becomes commercially available 2030+), and the math depends on the local gas pipeline access, capacity-factor expectations, REC pricing, and tariff-class treatment of self-generation. The BTM-generation page (strategy/btm-generation-economics.md if it exists; if not, create it) needs a 'PJM NCBL Framework 2(c)' section that walks through the economics on a 200 MW hyperscale site under each of the three sub-frameworks (curtailment-only, diesel-backup, BYOG). (4) The FERC filing path is the procedural hook for Cliff's Layer-5 live-docket product. Once PJM files the NCBL tariff at FERC (target Q3-Q4 2026), it becomes a federal docket with formal stakeholder comment process, ALJ proceeding, and final order — exactly the kind of regulatory-text-ingestion-and-summarization workload Cliff's product is built for. The pjm-er26-1088 page should be expanded to cover the parallel NCBL docket; the two will run on different procedural tracks but will inform each other (NCBL provides the tariff structure for new large loads; ER26-1088 provides the co-location structure for new generation behind the load). The intersection is the AI-data-center-with-BTM-gas configuration that hyperscalers are now sizing for. (5) The press framing is the political ceiling, not the technical text. Modo Energy's careful read of the document confirms PJM does not explicitly prioritize residential over data center load — but the Daily Caller / yournews May 10 framing characterizes it that way, and that framing will dominate state-PUC reading and political reaction across the seven PJM states with concentrated data-center activity (VA, MD, PA, NJ, IL, OH, NC). The implication for Cliff's risk module: the political-economy ceiling on PJM-state data-center entitlement is now closing faster than the technical regulatory text alone would suggest. Sites in early-stage approval in any of these seven states should be flagged as 'press-cycle-vulnerable' through Q3 2026; sites with sub-50 MW initial buildouts but ≥50 MW total campus size should be flagged as 'aggregation-risk' under the 50 MW threshold convergence. Translation for investor-updates/2026-05-12.txt: the single biggest grid operator in the country just released the strategy document that tells data center developers they will pay more, get less reliable service, or bring their own generation. PJM did not say 'PA-style 50 MW tariff' or 'OR-style 1¢/kWh surcharge' explicitly, but the structural direction is identical to what four state PUCs separately proposed in the prior two weeks, which is the kind of cross-jurisdictional alignment that's only legible in real-time when you're tracking the regulatory text at LLM-ingestion cost.
