Queue AE2-120 — Probability of Deliverable MW
Baseline assessment of AI datacenter readiness, covering fiber access, interconnection timelines, curtailment risk, and permitting hurdles. Scores above 85 signal “deploy now” sites, 70-84 require 6-12 months of prep, and anything below 70 needs heavy investment or an alternate location. Avoid costly missteps by pairing this scorecard with power mitigation tactics from the [ERCOT Curtailment Playbook](/playbooks/ercot-curtailment-playbook-2025) or queue navigation insights in the [PJM Interconnection Guide](/playbooks/pjm-interconnection-queue-guide-2025).

Readiness Market Signals
Power availability, interconnection queues, and fiber access now dictate AI siting. The 2026 "Power-First" development paradigm means grid capacity outweighs latency. Expect 24-36 month queues. SMR (Small Modular Reactor) roadmaps are becoming a key differentiator for 2030+ readiness. Close fiber gaps early, but prioritize power contracts above all.

How Readiness Moves the IRR
Timeline slippage and mitigation capex crush project IRR. A 50MW rollout on a Tier 1 site (score 85+) energizes in ~6 months with <$5M in enabling spend. A Tier 3 site (<70) often needs $15-25M in upgrades and adds 12-18 months before first revenue—equating to $150-230M in deferred GPU lease revenue at $12-18M/month. Model both paths inside the [LCOC / IRR calculator](/tools/lcoc-irr-dscr), layering in curtailment penalties from the [ERCOT Curtailment Playbook](/playbooks/ercot-curtailment-playbook-2025) or PJM queue delays to surface true NPV impacts.

Critical Readiness Factors for AI Deployments
AI datacenter readiness assessment evaluates five interconnected infrastructure dimensions, each with specific thresholds determining deployment viability. (1) Fiber connectivity: sites must be within 10 miles of tier-1 fiber backbone to achieve <2ms latency to major internet exchanges at reasonable extension costs (<$2M). Beyond 10 miles, fiber costs escalate to $3-5M and introduce 4-6 month construction delays. (2) Substation capacity: local substations must have 1.5-2x your load capacity available (75-100MW available for 50MW deployment) to handle redundancy requirements and peak demand without triggering expensive substation upgrades ($10-20M, 12-18 months). (3) Interconnection queue position: evaluate both queue length (number of projects ahead) and historical completion rates. ERCOT shows ~60% queue completion rates; PJM ~40%; CAISO ~35%. Projects in position >100 face severe timeline uncertainty. (4) Curtailment/reliability metrics: analyze historical curtailment hours (target <5% annual hours), grid stability scores, and whether site qualifies for demand response programs that monetize curtailment. (5) Permitting environment: evaluate local permit approval timelines (3-12 months typical), environmental review requirements, and community opposition risk. Sites in designated industrial zones streamline permitting versus greenfield locations.
Our readiness scoring framework (0-100 scale) translates infrastructure assessments into deployment timeline expectations and risk profiles. Tier 1 (85-100 points): "Deploy immediately" sites with fiber <5 miles, substation capacity >1.5x load, queue position <20, curtailment <5%, and favorable permitting. Typical timeline: 3-6 months from site selection to power-on. Tier 2 (70-84 points): "Good enough" sites requiring moderate infrastructure work—fiber extensions 5-10 miles ($1-3M, 3-6 months), substation upgrades <$10M, queue position 20-50, curtailment 5-10%. Timeline: 6-12 months. Tier 3 (50-69 points): "Development required" sites needing significant investment—fiber >10 miles, major substation work ($10M+), queue position >50, curtailment >10%, or complex permitting. Timeline: 12-24+ months. Below 50 points: consider alternative sites unless strategic factors (tax incentives, land costs, long-term power contracts) justify extended timelines and infrastructure investment. Most successful AI datacenter projects target Tier 1-2 sites to minimize deployment risk and capital requirements.

Implementation Guide: Advancing Site Readiness
Implementing site readiness assessment for PJM interconnection queue AE2-120 time to power requires systematic evaluation of infrastructure factors. Begin with desktop analysis using publicly available data: fiber route maps, utility substation locations, interconnection queue databases, and permit records. Conduct site visits evaluating physical constraints: proximity to fiber points-of-presence, distance to substations, land availability for expansion, and environmental/permitting risks. Engage utility providers for preliminary interconnection studies: request available capacity at nearby substations, typical interconnection timelines, and upgrade requirements for your load profile. Analyze historical grid data: curtailment frequency, reliability metrics, and power pricing patterns. Evaluate regulatory environment: permitting timelines, environmental review requirements, and community acceptance risks. Score sites across readiness dimensions (fiber, power, interconnection, curtailment, permitting) using standardized rubrics to enable objective comparison. For sites scoring 70+, proceed with detailed due diligence: formal interconnection applications, fiber provider negotiations, and permit pre-filing consultations. Build contingency plans for infrastructure gaps: fiber extensions, substation upgrades, or alternative site consideration if readiness scores prove lower than initial assessment.
Readiness Assessment FAQ
**What is a good readiness score?** Scores 85+ indicate immediate deployment capability (3-6 months). 70-84 represents good sites requiring moderate work (6-12 months). Below 70 demands significant infrastructure investment or extended timelines (12-24+ months). **How long does interconnection take?** Timelines vary by region: ERCOT 12-24 months, PJM 18-30 months, CAISO 24-36 months for large loads (50-100MW). Sites with existing available substation capacity can reduce timelines by 40-60%. **What is curtailment risk?** Curtailment measures how often grid operators reduce your power consumption during supply constraints. ERCOT shows 5-12% annual hours, PJM 2-5%, CAISO 8-15%. Each 10% curtailment costs roughly $1-2M/month per 50MW deployment in lost revenue. **How far can I be from fiber?** Target <10 miles from tier-1 fiber backbone. Beyond 10 miles, extension costs escalate to $3-5M and introduce 4-6 month delays plus latency penalties impacting distributed training performance. **Can I improve a low-readiness site?** Yes, but costs vary significantly. Fiber extensions <10 miles cost $1-3M. Substation upgrades run $10-20M+ and take 12-18 months. Queue positions cannot be accelerated without changing sites. Evaluate improvement costs versus alternative site selection.
