| #### Electricity generation mix
| unit: none (fraction) dimension: region, energy carrier

The indicator shows the share of electricity generated by the various types of inputs. In the TIMER energy model, several options exists to generate electricity. Electricity can be generated in thermal power plants using solid, liquid or gaseous fuels, in hydropower plants and in non-thermal power plants referring here to power plants based on nuclear fuels, geothermal heat and/or renewable sources such as wind and solar. Within the categories of solid, liquid and gaseous fuels, a distinction is made between fossil-fuel based coal, heavy and light oil (products) and natural gas, and traditional and commercial biomass-derived fuels. Each of the fuels and options has its specific conversion efficiency and investment costs. For non-thermal power plants the conversion efficiency is always equated to one.

| #### Installed capacity
| unit: 1000 MW (thousand MegaWatt) dimension: region, energy carrier

Electricity is being generated in four distinct, aggregate capital stocks representing four types of powerplants: thermal, hydropower, non-thermal nuclear and non-thermal wind/solar/other renewable. They operate with different load factors and different time-dependent fuel conversion efficiences and specific investments costs. Thus, the installed capacity determines the electricity that will be or can be produced.
