This chart shows the integral costs for flexible electricity demand technologies. It is defined in the documentation which types of electricity demand are considered flexible. Each bar shows the costs per produced unit of output for a certain flexible electricity demand technology. For different technologies the type of energy output can differ. Three costs categories are distinguished: CAPEX, OPEX and electricity costs. The electricity costs are calculated using the hourly electricity price and the hourly electricity consumption by a technology. For power-to-gas, the hydrogen price is given as a reference price. For electricity storage, the reference price is the integral revenue, meaning the average revenue per produced unit of electricity. The integral costs therefore depend on assumptions made about the costs and efficiencies of technologies, which you can change in the Cost & efficiencies section. It also depends on the installed capacity and willingness to pay of technologies, which can be changed in the Flexibility section.
