Introduction and general considerations
Technology assumption dataset list costs, efficiencies, emissions and lifetimes of energy conversion, storage and transmission technologies. Costs include investment costs, fuel costs, emission costs and variable and fixed operational and maintenance (VOM and FOM) costs.
Typically they provide an analysis of historical values and project future values (e.g. for 2030, 2050) with appropriate uncertainty ranges. Projections must be treated with caution given that the costs of some technologies (solar, offshore wind and batteries) are changing fast.
The databases have very different scope, with some covering only renewable technologies, while others include all generation, heating and storage technologies.
Values may be region-specific, reflecting local experience with the technologies and local conditions that may e.g. affect costs (such as the distance of offshore wind sites from the shore).
