Benchmark decommissioning costs against real European project data
Decommissioning aging nuclear reactors costs €1.4B and takes 22 years after decades of safety failures
DecomBench lets utilities upload project plans and instantly see how their forecasted costs and 22-year timelines compare to anonymized completed projects. It surfaces specific opportunities to save tens of millions while maintaining regulatory safety standards.

See exactly how your €1.4B decommissioning plan compares to real European outcomes. Cut costs and timelines with data, not hope.
Offer free benchmark runs to decommissioning project directors at EDF, RWE, and Fortum in exchange for contributing anonymized historical data. Use existing relationships from previous nuclear projects and offer co-branded benchmark reports they can present internally.
Strong in construction
No nuclear-specific benchmark database
Nuclear-only anonymized dataset
Network effect: every new benchmarked project makes the dataset more valuable. Data moat grows faster than competitors can copy.
Massive wave of European reactor retirements beginning 2025-2035 combined with inflation making historical estimates useless
Utilities reluctant to share cost data
Strong anonymization guarantees and reciprocal value (free benchmarks for contributors)
Building accurate benchmark algorithms
Start with rule-based matching, add statistical models after initial data collected
Success: At least 6 agree to contribute historical data
Success: Users find at least 2 actionable insights per benchmark
