Fervo Energy
Fervo Energy is building the world's largest enhanced geothermal project. The company secured USD 421M in non-recourse debt and is targeting an IPO. We ran it through ImpactAccounting.ai to model its full societal impact, then used the Prediction agent to project how that impact scales with growth.
The analysis was delivered in minutes — not weeks.
Headline results
| Metric | Value |
|---|---|
| Net societal value | USD 65.3M |
| SROI | 8.17x |
| Investment base | USD 1.2B |

What drives the impact
The dominant positive pathway is avoided fossil and peaking generation — worth USD 35.4M, driven by 23,460 MWh of displaced fossil fuel electricity. Enhanced geothermal provides firm, baseload clean power, directly offsetting carbon-intensive generation.
Other significant positive pathways include:
- Employer taxes and social insurance contributions from a growing workforce
- Infrastructure investment spillovers from drilling and construction activity
- Avoided grid instability costs from providing dispatchable renewable capacity

What the model flags as risk
ImpactAccounting.ai doesn't just show the upside. The analysis identified a material negative pathway:
Other negative pathways include supply chain costs (drilling, logistics), operational energy consumption, and land use during construction.

Bottom-up, not top-down
Every number in the Fervo analysis traces back to a specific data source or assumption — not sector averages, not input-output modeling. ImpactAccounting.ai maps 50-60 individual impact pathways per company, each with its own decomposition:
Activity → Output → Outcome → Monetary value
The platform shows the equations, the geographic weighting, and the source citations for each pathway. Everything is auditable.
Multi-year scenario modeling
Beyond the current-year analysis, the Prediction agent automatically generated three growth scenarios for Fervo — conservative, base, and accelerated build-out trajectories — projecting how net societal value grows as generation capacity, wells drilled, and workforce expand year over year. Custom scenarios can also be defined via the AI Chat.

Data validation
The analysis flags exactly which assumptions need verification with the company:
- Projected generation capacity and capacity factor
- Drilling cost per well and wells planned
- Grid displacement factor for the target region
- Workforce projections and average compensation
This gives investors a concrete due diligence checklist — not a generic questionnaire.
Why this matters for investors
A traditional ESG analysis would tell you Fervo is a clean energy company with positive environmental impact. ImpactAccounting.ai tells you:
- How much societal value it creates (USD 65.3M)
- Where the value comes from (avoided fossil generation, jobs, infrastructure)
- What could go wrong (demand rebound, supply chain emissions)
- How sensitive the result is to key assumptions
- What to verify with the company before relying on the numbers
This is the difference between a checkbox and a valuation.
