[Jan. 2026] The valuation of used power plants and their key components requires a high degree of technical, market and regulatory expertise. Age, usage, market environment and legal framework all have an impact on the expected re-sale power plant rest-value. Simplified depreciation approaches or flat-rate valuation models often fail to do justice to this complex issue in practice.
To provide an answer to the above, troveo© has developed a standardised evaluation method that systematically combines technical service life, current operational conditions and realistic market prices. The aim is to provide a transparent and reliable power plant rest-value assessment that offers customers a reliable basis for decision-making with respect to a potential resale process as well as for calculating losses due to changing regulatory and accounting matters.
The troveo© team has more than 15 years of experience in valuing existing power plants and determining their power plant rest-value based on world-wide market data and individual, often on-site technical assessment(s). This expertise is based on its own brokerage activities, close cooperation with partners, continuous market analysis and power plant assessments. An internal database of sales offers provides extensive information on several thousand current and former sales advertisements for power plant units, generation units and key components.
The above has led to the creation of an additional comprehensive database containing the current new prices of essential, valuable power plant components. This database is continuously maintained and updated: AI-supported processes assist among other with data reconciliation, plausibility checks and deviation detection, in order to generate consistent and comprehensible market prices. In addition to new prices, market-oriented resale values and current scrap values are also systematically taken into account.
This bundled knowledge enables a structured, market-oriented, and cost-efficient valuation of a power plant rest-value. For customers, this means reliable financial values that are technically sound, economically plausible and regulatory compliant. The current article published by the technical association of energy plant operators vgbe provides a detailed overview of the valuation method and the outcome.
In Germany in particular, the troveo© valuation is regularly used to ascertain rest-values for power plants in grid reserves. In numerous cases, troveo© has carried out independent valuations on behalf of transmission system operators. Due to its high degree of standardisation, the troveo© valuation is not only suitable for determining bid prices, but serves also as a basis for compensation and balancing solutions between grid operators and power plant operators. It contributes to transparent decision-making processes and the stability of the energy system in the context of the energy transition process.
