The index series

The Endenex Decommissioning Cost Index quantifies current repowering and decommissioning costs, projects forward liabilities and benchmarks market provisioning

Observed market cost

Endenex DCI Spot

Derived from verified cost data from completed decommissioning and repowering projects — what owners and contructors actually spent, net of recovery. An independent, empirical benchmark reflecting a market-based distribution of outcomes.

Forward market cost

Endenex DCI Forward Curve

Anchored to the DCI Spot and adjusted over a long-term horizon for fleet evolution, supply chain dynamics, commodity markets, and regulatory change, it defines a forward-looking distribution of costs at a given future date.

Reported liability provision

Endenex DCI Reserve Benchmark

Derived from operator disclosures and financial reporting, it reflects how decommissioning liabilities are currently provisioned, providing a reference point to assess alignment with observed and forward market distributions.

WHO USES ENDENEX INDICES

Decision-grade intelligence for every stage of the asset lifecycle

Investors

Whether acquiring wind, solar, or battery storage, Endenex provides the independent cost benchmark to evaluate decommissioning provisions, test vendor assumptions, and price end-of-life risk into investment decisions.

Owners & Asset Managers

The Endenex DCI is being established as a structured external reference for reserve benchmarking, forward liability modelling and portfolio-level oversight of decommissioning exposure — supporting board reporting, audit review, surety bond sizing and capital allocation decisions.

Repowering Finance

For repowering and late-life refinancing, Endenex provides an independent reference for removal cost, recovery value and net site-clearing liability. This helps financing parties test legacy reserve assumptions, quantify transition cost and challenge value cases that rely on stale decommissioning inputs.
