A SKOS concept scheme defining specific types of electricity production used by Svenska Kraftnät. The scheme includes detailed concepts such as biomass, fossil fuels (e.g. coal, gas, oil), nuclear power, hydropower variants, wind (onshore and offshore), solar, marine energy, and energy storage. Each concept is linked to broader production categories and described with identifiers, multilingual labels, alternative labels, and definitions. The scheme supports consistent classification, interoperability, and exchange of detailed generation data across systems and data domains in the electricity market.
