Pennsylvania's Generation Pipeline at the Federal Cliff: Amending HB 502 Before the Tax-Credit Window Closes
Bottom line
Pennsylvania has 340 active electric generation projects in PJM's interconnection queue, totaling 10,421 MW of summer-peak capacity. Of those, 91 projects (1,758 MW) are ready to build — they have signed Generation Interconnection Agreements (GIAs) with PJM and have not yet reached commercial operation. They are stuck on state and local permitting. For the solar and wind subset of that population — 78 projects, 1,415 MW — the One Big Beautiful Bill Act's federal tax-credit deadlines threaten to void project economics within the next 14 months.
Governor Shapiro's Reliable Energy Siting and Electric Transition (RESET) Board legislation, HB 502, is the obvious vehicle to break the state and local permitting bottleneck. As currently drafted, however, the bill's 25 MW eligibility threshold excludes most of the projects at risk. Lowering the threshold to 10 MW would expand HB 502's coverage of the ready-to-build pipeline from 24% to 71% of projects, with no other change to the bill's structure. This memo lays out the queue context, the federal-cliff urgency, the permitting landscape under SB 6, and the coalition logic.
What's actually in PA's interconnection queue
Analysis of PJM's Planning Queues data — the snapshot the Penn ENVS 5100 Group 4 obtained from RMI, covering the legacy queue prior to the April 2026 Cycle 1 announcement.
340 active generation projects in Pennsylvania's PJM queue, 10,421 MW of summer-peak capacity (12,931 MW winter peak). This excludes withdrawn, deactivated, and already-in-service projects. It is the live development pipeline.
| Fuel | Projects | MW Capacity | Share of queue MW |
|---|---|---|---|
| Solar | 238 | 4,542 | 43.6% |
| Storage (standalone) | 30 | 2,119 | 20.3% |
| Solar + Storage (hybrid) | 51 | 2,059 | 19.8% |
| Nuclear | 2 | 847 | 8.1% |
| Natural Gas | 5 | 451 | 4.3% |
| Wind | 13 | 401 | 3.8% |
| Other | 1 | 3 | 0.0% |
Two observations worth foregrounding.
First, Pennsylvania's active queue is overwhelmingly clean energy. Solar, storage, and solar+storage hybrids together account for 8,719 MW — 84% of the active pipeline. Natural gas is 4%. The conventional public framing of PA as a fossil-fuel state describes the existing fleet, not what developers are proposing to build. The bottleneck question is: how much of this 8,700 MW does PA actually capture?
Second, Pennsylvania's clean-energy queue is overwhelmingly small- and mid-sized projects. The median project size in the active pipeline is well under 25 MW. As we'll see, this matters enormously for HB 502's threshold design.
The GIA-posted urgent universe
Of the 340 active projects, 91 have executed Generation Interconnection Agreements with PJM and have not yet reached commercial operation — the universe PJM publishes as its "Ready to Build" list. For these projects, the engineering review is complete. PJM has determined they can be safely interconnected, what network upgrades are required, and at what cost. The grid operator has signed an agreement with each developer. They are not waiting on PJM. They are waiting on people.
| Fuel | Ready-to-build projects | MW Capacity |
|---|---|---|
| Solar | 77 | 1,394 |
| Solar + Storage | 7 | 150 |
| Storage | 5 | 149 |
| Nuclear | 1 | 44 |
| Wind | 1 | 21 |
| Total | 91 | 1,758 |
Most of the 91 ready-to-build projects were submitted to PJM between 2018 and 2020. They have been in development for five to seven years.
Of the 91 ready-to-build projects:
- 45 are in Engineering and Procurement status — actively moving toward construction
- 27 are Suspended — stuck behind some wall, very likely state or local permitting
- 17 are Under Construction — should make it
- 2 are Partially in Service / Under Construction
The Under Construction count is up significantly from earlier snapshots — a positive signal that some projects are breaking ground. Nine projects are now annotated as having moved into PJM's Cycle 1 or Cycle 2 reformed-process review.
This is the population that an HB 502 amendment can actually save. The earlier-stage projects (those still in System Impact Study or Facilities Study) need permitting reform too, but for them the binding constraint is still PJM. For these 91, the binding constraint is Harrisburg.
The federal cliff applies to 78 of the 91
The OBBBA tax-credit cliff is technology-specific. Solar and wind got the accelerated phaseout. Standalone storage and nuclear did not — they remain on the original IRA timeline.
For solar and wind:
- Cliff 1 — July 4, 2026 (begin construction): Projects must satisfy IRS Notice 2025-42's Physical Work Test by this date to retain credit eligibility under the four-year continuity safe harbor. The 5% cost safe harbor was eliminated for projects above 1.5 MW AC.
- Cliff 2 — December 31, 2027 (placed-in-service): Projects that miss the BOC date must be fully energized by year-end 2027 — functionally too short for utility-scale solar to complete siting, permitting, construction, and grid energization from a standing start.
Filtering the 91 ready-to-build projects to the federal-cliff-exposed technologies: 78 projects, 1,415 MW summer capacity / 2,588 MW winter capacity. This is the directly cliff-exposed universe. Every megawatt in this bucket is an investment that has already cleared engineering review, has agreements signed with the grid operator, and will lose its federal tax-equity backing if not under construction by July 4, 2026.
The 13 non-cliff-exposed ready-to-build projects (5 standalone storage, 7 solar+storage hybrid, 1 nuclear) are also held up by state and local permitting. They benefit equally from HB 502 reform — they just are not on a federal countdown clock. The cliff is what makes the timing urgent. The bottleneck is what makes the policy necessary. HB 502 reform serves both.
What's holding them up: state agencies are faster — local zoning is not
Pennsylvania has done meaningful permitting reform at the state level since 2023. Governor Shapiro established the Office of Transformation and Opportunity (OTO) by executive order, launched the PA Permit Fast Track Program, and stood up PAyback — a money-back guarantee for delayed permits. In 2025, the General Assembly passed SB 6 (Phillips-Hill, R-SD-28), the Permitting Modernization Act, alongside the budget — codifying OTO and requiring annual public reporting on per-agency permit performance.
The 2023→2024 results, per OTO's 2025 Impact Report, are real:
Other reforms operating now: DEP's SPEED Program (Streamlining Permits for Economic Expansion and Development), the PennDOT HOP ClearPath Pilot (launched August 2025, expanding statewide in 2026), the PA Permit Accelerator cohort program, and a 13-governor bipartisan Federal Permit Reform Working Group co-led by Shapiro and Oklahoma Governor Stitt.
Pennsylvania has also published a public-facing DEP permit tracker (launched January 2025) where any application can be looked up by authorization ID, county, program area, type, or submission date. Each detail page shows real-time status, estimated processing time, and completion dates for each review step. Per OTO, zero DEP applications were overdue under PAyback as of February 2026. PennDOT's KPI dashboard became fully operational in 2025; a Department of Revenue dashboard is in development. Tracker: pa.gov/agencies/dep/data-and-tools/track-permits.
Why the 91 are still stuck
If the state-agency side is moving faster, why does this analysis still identify 27 ready-to-build projects in Suspended status and 45 stuck in Engineering and Procurement?
Three reasons.
1. The reforms are forward-looking. Most of the 91 projects were submitted to PJM between 2018 and 2020, before Fast Track existed. The state-permit time savings will accrue to projects entering the queue today — but the legacy ready-to-build population was already in motion when the reforms began.
2. Fast Track is a high-touch program, not universal. OTO's 2025 portfolio includes seven major Fast Track projects: three data centers, two commercial development sites, one innovation center, and one community energy project. Coverage is selective; small- and mid-sized solar developments do not all qualify.
3. The biggest constraint is local — not state. SB 6 and the OTO reforms target Commonwealth agencies: DEP, PennDOT, L&I, DCNR. They do not touch local township zoning, county siting ordinances, or municipal special-exception processes, which is where the binding constraint for utility-scale solar in rural PA actually sits. The Shapiro administration's own 2025 Regional Forums confirmed this. Across 12 forums in 10 regions, four themes emerged consistently. The first:
Many municipalities, especially in rural areas, lack the staff and resources needed to plan, manage development, or pursue public funding. — OTO Impact Report 2025, summarizing 2025 Regional Forum findings across 10 regions
Inconsistent permitting decisions across regions, anti-solar local ordinances, and municipal-staff capacity constraints are exactly the gaps SB 6 cannot close. HB 502's preemption mechanism — empowering a state-level RESET Board to issue Certificates of Reliable Energy Supply (CRES) and override local denial for projects above a threshold — addresses precisely this gap.
Stated cleanly: SB 6 made the state side faster. HB 502 amendment expands state authority to override the local side for projects above a threshold. Lowering that threshold to 10 MW is what catches the cliff-exposed pipeline.
The HB 502 threshold problem
In April 2025, HB 502 — the Reliable Energy Siting and Electric Transition (RESET) Board bill — was introduced as part of Governor Shapiro's Lightning Plan. The bill establishes a state-level siting authority, issues Certificates of Reliable Energy Supply (CRES), and preempts local land-use controls for projects that receive a CRES. It includes a 90-day RESET Board determination clock, a 45-day public hearing window, and a 180-day Environmental Hearing Board appeal window. PEC, NRDC, and MAREC support the bill in concept. The PA Building and Construction Trades Council is named for inclusion in the Siting Advisory Council.
The problem: the eligibility threshold is set at 25 MW. This was probably chosen as a generic "utility-scale" default. It does not match the actual size distribution of PA's interconnection pipeline — for any technology.
| Threshold | Active projects covered | % of projects | % of MW Capacity |
|---|---|---|---|
| ≥ 25 MW (current HB 502) | 100 of 340 | 29.4% | 77.0% |
| ≥ 20 MW | 128 of 340 | 37.6% | 82.7% |
| ≥ 15 MW | 142 of 340 | 41.8% | 85.0% |
| ≥ 10 MW | 214 of 340 | 62.9% | 93.4% |
| ≥ 5 MW | 293 of 340 | 86.2% | 98.9% |
The same cuts on the 91 ready-to-build PA projects are sharper:
| Threshold | RtB covered | % of RtB | MW Capacity |
|---|---|---|---|
| ≥ 25 MW (current) | 22 of 91 | 24.2% | 1,052 |
| ≥ 20 MW | 25 of 91 | 27.5% | 1,120 |
| ≥ 15 MW | 27 of 91 | 29.7% | 1,153 |
| ≥ 10 MW | 65 of 91 | 71.4% | 1,610 |
| ≥ 5 MW | 82 of 91 | 90.1% | 1,743 |
And on the federal cliff-exposed (solar + wind) ready-to-build subset:
| Threshold | Cliff-exposed covered | % | MW Capacity |
|---|---|---|---|
| ≥ 25 MW (current) | 17 of 78 | 21.8% | 801 |
| ≥ 20 MW | 19 of 78 | 24.4% | 845 |
| ≥ 15 MW | 21 of 78 | 26.9% | 878 |
| ≥ 10 MW | 55 of 78 | 70.5% | 1,284 |
| ≥ 5 MW | 70 of 78 | 89.7% | 1,401 |
The single most consequential amendment to HB 502 — measured in megawatts saved before the federal cliff — is lowering the threshold from 25 MW to 10 MW. This change alone extends the bill's coverage of cliff-exposed ready-to-build capacity from 801 MW to 1,284 MW. Same procedural mechanism, same environmental safeguards, same labor standards — just a bigger eligibility universe.
The 10 MW threshold is also defensible on first principles. Below 10 MW, projects are typically community-scale and operate under different regulatory and economic frameworks (PA's net metering program, distributed generation tariffs). Above 10 MW, projects are unambiguously commercial-scale and reasonably subject to a state siting standard. The line is principled, not just convenient.
Geographic concentration
The 91 ready-to-build projects are spread across 37 counties. The largest concentrations:
| County | Projects | MW Capacity |
|---|---|---|
| Centre | 7 | 161 |
| Crawford | 7 | 141 |
| Erie | 5 | 129 |
| York | 7 | 124 |
| McKean | 2 | 122 |
| Bucks | 1 | 100 |
| Somerset | 5 | 96 |
| Adams | 5 | 88 |
| Mercer | 4 | 68 |
| Columbia | 6 | 67 |
| Indiana | 1 | 66 |
| Jefferson | 2 | 59 |
| Clearfield | 5 | 56 |
| Monroe | 1 | 48 |
| Union | 4 | 48 |
These are overwhelmingly rural counties represented by Republicans in the State Senate. The political point matters: this is not a Philadelphia or Pittsburgh issue. The host municipalities stand to gain construction-phase tax base, PILOT revenue, and middle-class trades jobs. The legislators who actually represent these projects are the legislators whose districts benefit most directly.
The interactive Politics map on the home page shows every Senate and House district with stuck capacity, and overlays HB 502 / SB 502 cosponsorship. The pattern is stark: districts with stuck capacity are overwhelmingly Republican-held; cosponsors are overwhelmingly Democratic.
Proposed amendments to HB 502
In addition to the threshold change, three other amendments would tighten HB 502 around the federal-cliff problem without altering its overall structure:
1. Lower the generation threshold to 10 MW. As described above. The storage threshold (currently 10 MW / 4-hour) is appropriate as drafted.
2. Add a fast-track lane for projects with executed PJM Generation Interconnection Agreements. Any project with a GIA on file with PJM as of the bill's effective date receives an expedited CRES review — the 90-day RESET Board clock is shortened to 45 days, and the public-hearing window compresses to 21 days. Justification: engineering review is complete and the federal deadline is non-negotiable. The carve-out is narrowly scoped, time-limited, and tied to an objective external trigger (the PJM agreement), which insulates it from "this is just a giveaway" attacks.
3. Lock in the Building Trades Council seat on the Siting Advisory Council. PEC's testimony already recommended this. Make it explicit in statute. The PA Building and Construction Trades Council provides the labor coalition's permanent role in implementation, and aligns with NABTU's federal-level partnership on H.R. 8477.
4. Sunset alignment. The fast-track lane sunsets December 31, 2030 — the outer edge of the federal continuity safe harbor for projects beginning construction in 2026. The base RESET Board structure remains permanent.
These amendments sit comfortably inside the existing legislative architecture. They do not require a new bill. They require a markup.
Engaging the strongest counter-argument
The MPL Law Firm published a critique of HB 502 in September 2025 arguing that interconnection, not land use, is the real bottleneck — that the PA Municipalities Planning Code already imposes timing limits on local review while PJM's queue has historically had none.
This is partly right and exactly why both reforms matter. PJM's "first-ready, first-served" reform and the Cycle 1 process are addressing the interconnection side. HB 502 addresses the state and local side. The data above shows the second bottleneck is real: 91 projects have already cleared PJM's gauntlet and remain stuck. The MPL critique is best read as "don't let HB 502 be the only thing you do," not "don't pass HB 502."
The PJM-wide attrition data reinforces the point. Per PJM's March 2026 disclosure, of the 103 GW of GIAs executed across PJM since 2020, only 23 GW reached commercial operation — a 77% withdrawal rate before energization. For PA's 78 cliff-exposed solar and wind projects, the historical attrition rate plus a hard federal deadline 14 months out is a worse setup than that 77% baseline implies. State policy intervention is the only mechanism available to push the conversion rate higher in time.
The bills, at a glance
The federal coalition signal
On April 23, 2026, Rep. Brian Fitzpatrick (R-PA-1) introduced H.R. 8477, the American Energy Dominance Act, with cosponsors Lawler (R-NY-17), Miller (R-OH-7), and Carey (R-OH-15). The bill removes OBBBA's accelerated 45Y/48E deadlines. It was developed in direct partnership with North America's Building Trades Unions (NABTU) — the federal umbrella for IBEW, EAS Carpenters, and the rest of the building trades.
The bill is unlikely to pass before the 2026 midterms. That is fine. What matters for our purposes is the political alignment it surfaces:
- Federal trades + a PA Republican congressman = pushing federal extension.
- State trades + Shapiro Democrats = pushing HB 502.
These are the same coalition at two levels of government. State action on HB 502 amendment is the rational complement: if H.R. 8477 passes, PA captures more of the federal extension; if it does not, PA's amended HB 502 is the only thing standing between developers and the abandonment of 1,300+ MW of vetted, contracted projects.
Coalition map
In:
- PA Building and Construction Trades Council — already named in the bill's Siting Advisory Council; NABTU has taken the federal position
- MAREC and Mid-Atlantic solar/storage developers — Doral Renewables (Philadelphia-based) testified at the May 2025 hearing
- PEC, NRDC, Mid-Atlantic Renewable Energy Coalition — supportive of HB 502 in concept; the threshold amendment is consistent with their testimony
- Shapiro administration — bill is in the Lightning Plan
- Pennsylvania Capital-Star and state press — already covering HB 502; will cover the cliff angle
Negotiable:
- Local government associations (PA League of Cities, PSAB) — opposed to local preemption. Negotiable on environmental safeguards, public-hearing windows, and PILOT revenue protections
- Environmental-justice community — concerns about the RESET Board lacking specific siting safeguards near schools and residential areas. Brownfields / disturbed-land preference and prime-ag exclusion are designed to respond
- Republican legislators in counties with stuck projects — politically asymmetric: they get to say yes to local trades jobs and rural tax base while distancing from "Shapiro's preemption bill" framing. Need a Republican carrier for the threshold amendment specifically.
Opposed:
- Discretionary local opposition (NIMBY networks) — same actors who oppose multifamily housing and transmission. Eligibility gates blunt their best arguments
- Hard-anti-renewables actors — smaller in PA than in some other states; their argument loses force when the lead federal vehicle is Republican-sponsored
Recommended sequencing
- Coalition validation. Run the threshold amendment past Building Trades Council (state level), MAREC, and PEC before circulating publicly. The 25 MW → 10 MW change is the high-leverage ask; everything else is supporting.
- Republican legislator outreach. Identify state House and Senate Republicans whose districts contain GIA-posted projects. The Politics map on the home page surfaces every name. Initial cut for Senate side: Crawford / Mercer / Lawrence (Sen. Brooks SD-50), Centre / McKean / Jefferson (Sen. Dush SD-25), Columbia / Northumberland / Snyder / Montour (Sen. Schlegel Culver SD-27), Adams / Franklin / Fulton (Sen. Mastriano SD-33), Indiana / part of Westmoreland (Sen. Pittman SD-41), York (Sen. Phillips-Hill SD-28). The pitch: this is your district's tax base and your district's union jobs.
- Public memo and dashboard. BPN publishes this memo and the accompanying interactive dashboard (Substack publication coincides with HB 502 reintroduction or markup activity).
- Coordinate with PJM Cycle 1 narrative. PJM has promised a state-level breakdown of the 220 GW Cycle 1 intake in coming weeks. When that data drops, refresh the memo to include both the legacy queue (this analysis) and the Cycle 1 PA share (forthcoming).
- Penn Group 4 as the anchor citation. ENVS 5100 Group 4 — Brandon Licata, Nechama Lowy, Lexi Luong, Anna Phillips, Andrew Weng, Jie Ying — did the original threshold-analysis methodology. Their work is the foundation. BPN's contribution is connecting it to the federal cliff and the GIA-posted urgent universe across the full fuel mix. Credit them prominently.
Open data needs
- Cycle 1 PA breakdown. Forthcoming from PJM in coming weeks.
- Project-level permitting status. For the 22 Suspended GIA-posted projects, what specifically stalled them? FOIL territory or developer outreach.
- PILOT revenue and jobs modeling. NABTU jobs-per-MW methodology + PA DEP PILOT averages to size local economic impact for the Republican legislator pitch.
- MW Capacity vs MW Energy in HB 502. The bill says "capacity." Confirm whether that maps to PJM's MW Capacity (summer net) or MW Energy (winter net). For solar this matters — winter energy ratings often run substantially higher than summer capacity, so threshold semantics affect eligibility counts.
- Local zoning landscape. Survey the 37 counties for adopted solar siting ordinances, anti-solar moratoriums, and special-exception practice. Where local frameworks exist and are working, HB 502 preemption is less politically necessary; where they don't or are openly hostile, it is the only path.
- A comprehensive cross-venue project tracker. No canonical database currently exists that follows a single project across every venue it touches: PJM interconnection queue → state agency permits (DEP Chapter 102 / 105, PennDOT HOP, PUC siting where applicable) → County Conservation District review (where Chapter 102 is delegated) → County Planning Commission → township zoning hearing board → federal NEPA (where applicable). The state-side tools published since 2024 (DEP permit tracker, PennDOT KPI dashboard, PAyback) are real but cover only the state-agency layer. The local-permitting layer — which is where most of these 91 projects are actually stuck — is fragmented across 67 counties and roughly 2,500 municipalities. Building a publicly-accessible, project-level tracker that consolidates this is a future BPN tool concept; it is not within scope of this memo. As a sample finding, BPN's spot-check confirmed that Hoodlebug Solar Energy Center (PJM AF1-272, Indiana County) appeared on Indiana County Planning Commission's July 2025 meeting agenda — six years after its PJM submission, still in local zoning review. The pattern likely holds across most of the 27 Suspended projects.
Provenance and attribution
The threshold-analysis methodology — measuring how HB 502's eligibility floor interacts with the actual size distribution of PA's queue — originated in the December 2025 brief "Pennsylvania and PJM: Speeding Up Interconnection," authored by University of Pennsylvania ENVS 5100 Group 4: Brandon Licata, Nechama Lowy, Lexi Luong, Anna Phillips, Andrew Weng, and Jie Ying. The Penn group identified six policy recommendations spanning PJM-wide reform (grid-enhancing technologies, ERIS, PJM governance) and state-level reform (HB 502 threshold expansion). This memo extends their threshold recommendation specifically — adding the federal-cliff exposure overlay, the GIA-posted urgent-universe cut across the full fuel mix, the Politics-map analysis, and the SB 6 / OTO permitting context.
Penn Group 4 will be added as full co-authors of this memo upon collaboration in coming weeks.
