Grid & Power Constraints
Interconnection queue delays, power capacity shortfalls, and project-level impacts on infrastructure execution
Regional Grid Status
Interconnection Queue Timeline Trend
Median time from interconnection request to commercial operation has more than doubled since 2008. Only 19% of capacity that entered queues from 2000-2018 reached commercial operation (Berkeley Lab 2024). The 2025 Edition reports median duration increased from less than 2 years for projects built 2000-2007 to over 4 years for those built 2018-2024.
Projects with Power Constraints
All 7 tracked data center projects face power constraints ranging from queue delays to workaround deployments. Semiconductor fabs face moderate constraints (3 of 11 projects) but are generally manageable with utility partnerships. Battery, pharma, and automotive projects have standard industrial requirements with minimal power-related delays. Industry context projects (not in our RAID tracking) are included to illustrate broader market dynamics.
Data Centers (7 Tracked + Industry Context)
| Project | Power Need | Constraint | Status / Workaround |
|---|---|---|---|
Abilene, TX |
10 GW target | ERCOT Queue | Gas turbines deployed for immediate power. $1B+/year operating cost tradeoff. |
Susquehanna, PA |
960 MW planned | FERC Rejected | Limited to 300 MW. FERC twice rejected 960 MW co-location with Talen nuclear. |
Denton, TX |
260 MW | ERCOT Queue | +18 months for interconnection. 260 MW committed to OpenAI. |
Blackstone QTS Pennsylvania (Industry Context) PPL Territory, PA |
6+ GW shortfall | Generation Gap | PPL JV formed to build dedicated generation. Construction late 2028. |
Richland Parish, LA |
2+ GW | Turbine Shortage | Entergy $3.2B approved. Gas turbines sold out 5 years globally. |
Digital Realty Santa Clara (Industry Context) Santa Clara, CA |
48 MW | SVP Queue | Empty since 2019. SVP $450M upgrade due 2028 (Bloomberg Nov 2025). |
xAI Colossus (Industry Context) Memphis, TN |
2 GW target | Scaling | 250 MW live. MLGW substation built in 97 days (vs 2.5 yr norm). Scaling to 2 GW via gas turbines. |
Multiple |
9 GW potential | Nuclear PPA | Three Mile Island 837 MW restart secured via 20-yr Constellation PPA. Expected online 2027 (accelerated). $1B DOE loan closed Dec 2025. |
PJM Region |
$25B+ investment | Hydro PPA | $3B Brookfield deal (3 GW hydro). World's largest corporate hydro PPA. |
AWS/Talen Nuclear (Industry Context) Pennsylvania |
960 MW | FERC Blocked | Deal collapsed. FERC concerned about grid reliability impacts. |
Vantage Texas (Industry Context) Texas |
1.4 GW | ERCOT | Monitoring queue position. No material delay yet. |
Semiconductors (3 of 11 with Power Issues)
| Project | Power Need | Constraint | Status |
|---|---|---|---|
Phoenix, AZ |
~300 MW (6 fabs) | APS Secured | Infrastructure on track. APS $4B+ investment for corridor. |
New Albany, OH |
~200 MW | Grid Upgrades | Grid constraints secondary to financial distress. Delayed to 2030-31. |
Taylor, TX |
Multi-hundred MW | ERCOT | Queue issues secondary. Primary issue: no customers. |
Power Workarounds in Action
Companies are deploying creative strategies to bypass multi-year interconnection queues. Each approach trades cost, timeline, or control for speed to power.
Regional Supply Chain Ecosystems
Anchor projects create supplier dependencies that amplify both opportunity and risk. Delays at anchor facilities cascade through entire regional ecosystems.

FERC Actions
- Nov 2024 & Feb 2025: Twice rejected AWS/Talen 960 MW co-location citing grid reliability
- Aug 8, 2025: PJM launched Critical Issue Fast Path (CIFP) for accelerated rulemaking
- Dec 18, 2025: Ordered PJM to develop large load colocation rules, create 3 new transmission services
- Ongoing: Order 2023 reforms implementing to reduce queue bottlenecks. 75 GW of interconnection agreements reached in 2024 (record).
State & Regional Initiatives
- Texas SB6 (Jun 20, 2025): $100K+ study fees, site control required, curtailment mandates for 75+ MW loads
- Arizona (APS): $4B+ transmission investment for semiconductor corridor
- PJM: 46 GW cleared queue and free to build. Backlog clearance expected by Spring 2026.
- ERCOT: 233 GW large load queue (Dec 2025), contracted McKinsey for queue optimization
Investment Implications
Lowest Power Risk
- TSMC Arizona: APS $4B+ dedicated investment, power infrastructure on track, Q4 2024 CHIPS disbursements received
- Microsoft AI: Three Mile Island 837 MW secured via 20-yr PPA, $1B DOE loan closed, online 2027
- Google PJM: $3B Brookfield hydro PPA (3 GW), world's largest corporate hydro deal, avoids queue
- Hyperscalers with workarounds: Companies deploying gas turbines, nuclear PPAs, or utility JVs executing while queue-dependent projects wait
Highest Power Risk
- Queue-dependent projects: 4+ year median wait (Berkeley Lab 2025), only ~20% of queued projects reach operation (14% by capacity)
- ERCOT large loads: 233 GW queue vs ~7.5 GW approved, 73% data centers, speculative bubble concerns
- PJM region: 6,517 MW capacity shortfall, first in history, data center demand driving 94% of 32 GW growth
- Projects without power strategy: Samsung Taylor, CoreWeave Denton face secondary power constraints alongside primary business issues
Leading Indicators to Watch
- FERC colocation implementation: PJM filings due Jan-Feb 2026 for new transmission services (firm, non-firm, interim)
- PJM incremental auction: Feb 2027 for 2028/2029 delivery year, first test of CIFP solutions
- ERCOT queue reform: McKinsey engagement, solutions expected early 2026, PUCT SB6 rulemaking ongoing
- Nuclear restart progress: Three Mile Island NRC approval expected 2026, Palisades restarted Oct 2025
- Utility generation JVs: Blackstone/PPL Pennsylvania, additional hyperscaler deals expected
