In the Technology Catalogue, data for power generation technologies is  defined, standardized and presented following a consistent structure across all technologies.

Each technology in the catalogue is described through two main components: qualitative description and quantitative data. The qualitative section includes the technology principle, inputs, outputs, typical capacity, load flexibility, advantages and disadvantages, spatial requirements, water consumption, environmental aspects, employment, research and development status, and examples of existing projects. The quantitative section presents technical, operational, environmental, and economic parameters in a standardized format.

Content Category	Role in the Catalogue
Qualitative description	Explain what the technology is, how it operates, and where it is applied
Technical/energy data	Presents capacity, efficiency, ramping capability, lifetime, and construction time
Economic data	Presents capital costs, fixed O&M, variable O&M, and start-up costs
Uncertainty range	Indicates the variation range of key parameters
References	Identifies data sources and the basis for parameter development

All parameters are standardized to ensure comparability across technologies. Capacity and efficiency are expressed in net terms, meaning they account for the plant’s internal electricity consumption. Cost data are presented in constant 2025 USD and exclude taxes, such as VAT.

Mature technologies generally have lower uncertainty, while emerging technologies exhibit higher uncertainty, due to dependence on technological progress and future deployment conditions.
