Cost of expansion - High
estimate (€/MWh)
The implicit subsidies to the different technologies are calculated by subtracting the expected
price of electricity or heating input from the technology specific generation cost.
We estimate that EU governments can reduced their outlay on subsidies to renewable
energy deployment by €2-10 billion depending on the high or low cost estimates for renewable,
cf. Table A.16. 63 The estimate is the same for both scenarios as the assumed high
price of electricity in 2020 will render most renewable energy technologies profitable
without government subsidies.
63 We implicitly assume that Member States can coordinate on postponing the most expensive technologies.
