Make Smarter Siting and
Queue Decisions
Felix gives generation developers ISO-accurate transmission capacity data, upgrade cost forecasts, and scenario modeling across every major U.S. market — so you can move faster with more confidence at every stage of development.
Tighter Markets Demand
a Higher Standard of Interconnection Analysis
Interconnection is complex and costly if approached with incomplete data.
Felix transforms each phase of your development journey to make better decisions from day one.

Completion
- Manually study 10–20 sites via consultants & FCITC tools.
- No visibility into ISO cost impact until months later
- Spend 2–3 months on flawed shortlists
- Screen 1,000+ substations instantly across ISOs
- Visualize capacity + upgrade cost in real time
- Save weeks on land vetting and site selection
- Analyze two scenarios with minimal scope
- Simplified DC models risk lower accuracy.
- Limited analysis misses optimal, low-risk POIs
- Verify local assumptions before submitting IRs
- Run AC analysis per ISO criteria
- Test custom scenarios with proprietary data
- Submit without understanding risk or constraints
- Learn about major issues 12–18 months later
- Potential $700K+ wasted in deposits and development
- Predict upgrade costs before you apply
- Model scenarios to avoid risky sites
- Avoid false positives, reduce sunk costs
- Wait for ISO results to decide viability
- Consultants/TPEs take weeks per iteration
- No agility - miss window to revise or reposition
- Forecast bookend cost ranges early
- Run 100+ what-if scenarios instantly
- Adjust strategy in real time
- Projects dropped late in study process
- Unexpected upgrade costs derail schedules
- Lost revenue, credibility, and market advantage
- Proceed only with de-risked projects
- Confidently manage portfolio + timelines
- Improve investor trust and capital efficiency
Accuracy- First Methodology Meets Customized Insights
Felix enables interconnection teams to develop a custom view of the grid in the fastest, most efficient way possible
Felix runs ISO-accurate injection studies against your assumptions — queue drop offs, retirements, transmission upgrades — across every POI in a region simultaneously.
Your market intelligence, built into the model.
- 10x the speed and half the cost of using traditional tools
- Unlimited scenario iterations before your decision point deadline
- Your proprietary assumptions applied across every POI in a region simultaneously
Screen 1,000+ Substations in Minutes
Create your own heatmap across any ISO, updated with each model release, color-coded by capacity and upgrade cost exposure. Results on demand for every POI across a region — no manual GIS tracing, no consultant reports.
Felix's Prospecting Platform:
- Receive on-demand study results for every POI across a region
- Results consistently updated as queues, models, and methodology changes
- Input proprietary assumptions to get your own study results across every POI
- Felix's team of transmission experts support your green fielding teams
Stress-Test Your Best Sites Before You Commit
Deep-dive sensitivity analysis on a shortlist of priority POIs. Toggle local queue assumptions, run flexible custom scenarios, compare competing project scenarios — all re-running full ISO study methodology on your specific assumptions.
Felix's Local Studies Tool:
- Deep dive into results at a shortlist of priority sites
- Toggle local queue assumptions across flexible, across numerous custom scenarios
- Re-runs full ISO study methodology for fast, accurate results
- Compare scenarios based on knowledge of competing projects in the queue
- Why it matters : This is where your proprietary market intelligence becomes a quantifiable site-level view — before you spend on an IR deposit, land diligence, or consultant studies.
ISO-Aligned Results You Can Actually Trust
The reason other tools generate false positives isn’t a data problem — it’s a methodology problem. Felix replicates the exact study processes ISOs use, because it was built by people who ran those processes from the inside.
Methodology mirrors the ISOs
Felix replicates ISO injection study processes exactly — so your results reflect the network upgrades you’ll actually face.
Built by Transmission Experts
Felix’s team includes former planners and engineers from ISOs, utilities, and developers across every major U.S. market.
Proven at Scale
500+ GW modeled. $3B+ in ISO errors uncovered. 100+ developers trust us.
