The reference benchmark for decommissioning and repowering costs across utility-scale renewable power generation and flexibility assets. Built from verified primary-source project data. Published in accordance with IOSCO Principles for Financial Benchmarks.
The Endenex DCI is structured as three complementary series, each addressing a different dimension of decommissioning liability: realised cost, projected exposure and market provisioning.
Together they form a coherent analytical framework — linking observed market expenditure to forward cost trajectories and current balance sheet reserves.
Captures realised expenditure from completed repowering and decommissioning activity, normalised by asset class and jurisdiction. It reflects what the market has actually spent, net of recovery value, based on primary supply chain data. Spot values anchor the benchmark in empirical evidence and provide the reference point for all forward projections.
Extends Endenex DCI Spot into the future, constructing a time-specific cost estimate over a 10–25 year horizon depending on the underlying asset class. It incorporates structural drivers of cost evolution — technology change, commodity inputs, logistics and recycling constraints, and regulatory trajectory — producing a forward liability term structure rather than a single sensitivity.
Compiles operator-reported decommissioning provisions sourced directly from market participants and publicly disclosed filings. Published without analytical adjustment, it makes visible the aggregate state of market provisioning. When assessed against Endenex DCI Spot and Forward values, it quantifies the reserve gap at asset, portfolio and cohort level.
The Endenex DCI is constructed from primary data collected directly from the decommissioning value chain — asset owners, turnkey contractors, specialist subcontractors, recyclers, and salvage purchasers. Cost components tracked include mobilisation and logistics, civil and foundation works, structural dismantling, electrical removal, environmental reinstatement, and gross salvage receipts. Net Recovery Offset — salvage value net of extraction and processing costs — is tracked as a discrete component.
The methodology is documented in full and published separately. Endenex operates in voluntary compliance with the IOSCO Principles for Financial Benchmarks, including independence of governance, transparency of methodology, and conflicts of interest management. Endenex DCI is published for informational and analytical purposes. It is not intended to constitute regulated financial benchmark within the meaning of the UK or EU Benchmarks Regulation.
