US refining capacity slips; grid fast-track disputes delay new gas

Energy markets and infrastructure are showing near-term tightening signals. U.S. refining capacity declined in 2025, reducing operational buffer and potentially increasing vulnerability to supply disruptions.

At the same time, grid planning and generation interconnection are becoming more contested. PJM’s opposition to waiving parts of a fast-track review for a $2B gas-fired plant highlights continued backlog-driven friction, which can delay dispatchable capacity additions even as electrification and renewable deployment accelerate.

Policy and program design also matter for demand-side and power-supply buildout. Multiple state actions focus on scaling solar, improving residential efficiency, and clarifying agrivoltaics—implying that supply expansion will increasingly depend on permitting, standards, and customer affordability mechanisms rather than pure build-rate alone.

Top Signals

1. U.S. refining capacity declining—lower cushion for product supply

Signal strength: Developing

A reduction in operable refining capacity can shrink spare throughput, raising exposure to regional product shortages, volatility during outages, and tighter margins—especially relevant for planning fuel procurement and risk management.

Supporting evidence

  • U.S. refining capacity decreased during 2025 — EIA Today in Energy, 2026-06-29. Reports operable atmospheric distillation capacity fell to 18.2 million b/cd on Jan 1, 2026, down over 250,000 b/cd (~1%) versus Jan 1, 2025—indicating a continued capacity contraction trend.

2. PJM resists fast-track interconnection waivers for gas plant—delays likely

Signal strength: Early

Interconnection process friction can slow dispatchable capacity additions, affecting resource adequacy planning, price risk, and reliability outcomes. It also signals that developer timelines may face stricter governance as backlogs persist.

Supporting evidence

3. State policy accelerates solar deployment via incentives, permitting, and programs

Signal strength: Developing

Regulatory design is increasingly a key driver of solar scale—affecting project lead times, bankability, and customer adoption. For utilities and developers, these changes shift the risk from technology to execution (permitting, program rollout, and program eligibility).

Supporting evidence

4. Electrification and efficiency programs target bill risk via all-electric, heat-pump homes

Signal strength: Developing

When prices rise, demand-side measures become a primary tool to manage household cost exposure and grid load growth. Programs that cut energy use materially improve affordability and can reduce long-run peak demand pressure.

Supporting evidence

5. Low-carbon building investment trade-offs drive utility vs school funding decisions

Signal strength: Early

Budget allocation choices can shift demand for decarbonization technologies (e.g., HVAC) and affect the financing and pace of building upgrades—creating policy-driven uncertainty for utilities and contractors.

Supporting evidence

  • California’s choice: Cleaner air for schools or money for utilities — Canary Media, 2026-06-29. Presents a policy decision about nearly $200 million: whether to fund public school HVAC/plumbing upgrades for cleaner air versus sending funds back to utilities to lower bills—signaling potential diversion or reallocation of decarbonization investment.
