Master the PJM interconnection queue process and secure faster power connections for your AI datacenter projects.
Skim this TL;DR to understand the three moves that matter most before you wire deposits or lock in grid queues.
The PJM interconnection queue represents one of the most significant bottlenecks for AI datacenter development in the Mid-Atlantic region. With over 200 GW of generation and load projects currently in the queue, processing times have extended beyond historical averages. Recent policy changes and transmission planning updates have created both challenges and opportunities for datacenter developers.
Grid modernization efforts and transmission expansion projects aim to address capacity constraints, but implementation timelines remain lengthy. Understanding the queue process, network upgrade cost allocation, and timing strategies is crucial for successful project development. Alternative approaches, including behind-the-meter generation and energy storage integration, are becoming increasingly important for datacenter projects requiring expedited timelines. Use the [PJM Queue Analyzer](/tools/pjm-queue-analyzer) referenced in this playbook to model how different queue positions cascade into project IRR.

Understanding the key metrics is essential for making informed decisions about AI datacenter investments. Each index provides unique insights into different aspects of market conditions and project viability.
GLRI (GPU Lease Rate Index): Tracks market lease rates across different GPU models, regions, and lease terms. This index helps you understand whether current lease offers are above or below market rates and predicts future pricing trends based on supply-demand dynamics.
CSS (Curtailment Stress Score): Measures the likelihood and severity of power curtailment in specific grid zones. A higher CSS score indicates greater curtailment risk, which can impact datacenter operations and economics through reduced availability and increased backup power requirements.
TTPS (Time-to-Power Score): Assesses the timeline required to secure power interconnection and begin operations. This score incorporates queue positions, transmission upgrade requirements, and regulatory processing times to provide realistic deployment timelines.
PAY (Power-Adjusted Yield): Combines GPU revenue potential with power costs and curtailment risks to calculate actual project returns. This metric provides a more accurate picture of project economics by accounting for location-specific power conditions and constraints.
When evaluating potential datacenter sites, consider these metrics together rather than in isolation. A site with excellent GPU lease rates but high curtailment risk may have lower overall returns than a site with moderate lease rates but stable power supply. Feed each scenario into the [LCOC / IRR calculator](/tools/lcoc-irr-dscr) to translate score changes into cash-flow impact.
Managing the PJM interconnection process requires careful planning and strategic decision-making. Start by conducting preliminary feasibility studies to identify optimal interconnection points and potential network upgrade requirements. Engage with transmission operators early to understand capacity constraints and potential mitigation strategies.
Prepare comprehensive interconnection applications with detailed technical specifications and operational requirements. Consider multiple interconnection scenarios to provide flexibility and backup options. Monitor queue positions and study progress actively, being prepared to respond to information requests and negotiate network upgrade cost allocations.
Develop alternative power supply strategies in case of interconnection delays, including behind-the-meter generation, energy storage, or temporary mobile generation solutions. Maintain regular communication with PJM staff and other stakeholders to identify potential bottlenecks and mitigation opportunities. Consider joint development approaches to share network upgrade costs and accelerate timelines. Use outputs from the [PJM Queue Analyzer](/tools/pjm-queue-analyzer) to prioritize which feeder or substation delivers the highest ROI.
Example 1: 500 MW Hyperscale Project in Northern Virginia
A hyperscale developer submitted a 500 MW interconnection application in PJM's northern region, receiving an initial 42-month timeline. Through strategic engagement with transmission planners and agreement to fund specific network upgrades, the timeline was reduced to 28 months. The developer also secured temporary mobile generation to begin limited operations 18 months earlier and used the [PJM Queue Analyzer](/tools/pjm-queue-analyzer) to reprioritize feeder selections.
Example 2: AI Startup in Central Pennsylvania
An AI startup requiring 50 MW of power faced 36-month queue timelines in Central Pennsylvania. By pursuing a behind-the-meter generation approach with 30 MW of natural gas generation and battery storage, the company achieved operational readiness in 14 months. The hybrid approach provided power costs 15% below grid rates with significantly higher reliability, unlocking a 220 bps improvement in modeled IRR.

Common questions about interconnection queues & timeline for AI datacenters.
Initial estimates often prove optimistic; actual timelines average 30-40% longer than initial projections.
Queue positions cannot be directly transferred, but project acquisitions include associated queue positions.
Primary factors include high network upgrade costs, extended timelines, and changing market conditions.
Limited fast-track options exist for certain projects, but require specific criteria and additional fees.
Costs are allocated based on beneficiary rules and can be negotiated between multiple projects sharing upgrades.
