Measuring the impact of policy changes
The calculations in this report build on the NECP assessment published by Ember in 2020, applying changes to energy policies announced by national governments between 2020 and 2022. In this period several events impacted political decisions – the COVID-19 pandemic in 2020, the gas crisis in 2021, the war in Ukraine in 2022. Many coal phase-outs were announced during COP26 in 2021, together with clean power by 2035 commitments from major economies such as the UK, Germany and USA.
The changes in policies are across a number of varying metrics – e.g. wind and solar capacity increases, coal phase-out dates, RES share in generation goals. All these targets have been transformed into consistent share in generation figures for RES, fossil fuels and clean energy. Clean electricity includes wind and solar and other low-emission sources like hydro and nuclear, and excludes unabated fossil fuels, such as coal and gas.
Country-level data and references are available in the attached spreadsheet. Capacities were transformed into generation using country-level capacity factors derived from the EU Commission’s MIX scenario. Where coal phase-out dates were announced and no estimates on the generation were provided, a linear reduction of generation from 2021 towards the phase-out date was assumed. One of the exceptions was Romania, where the Recovery and Resilience Plan assumes that in 2030 one last 810 MW unit will operate – to estimate its generation we’ve assumed a capacity factor of 20%. The other exception was Czechia, where an estimate of 15 TWh coal generation in 2030 was available in Ember’s previous briefing, aligned with a 2033 phaseout date.
The resulting additional RES generation is assumed to replace fossil fuels, not nuclear energy. An exception is Hungary, where the high clean share is achieved through a nuclear program. In other CEE countries – Croatia, Czechia, Slovenia, Romania, the coal generation decreases are assumed to be replaced by renewables – not gas (due to geopolitical reasons) nor nuclear, since it is unlikely that new nuclear projects will be commissioned by 2030 (e.g. the expansion of the Dukovany plant in Czechia is planned for 2036, three years after the coal phase-out, which means the coal generation will need to be replaced with renewables).
In some cases, clean generation might exceed 100% – e.g. in Denmark, the Netherlands, Sweden, France. Overproduction is generally seen as positive – as it could provide economic benefits to host countries and decrease fossil generation in neighbouring countries. This was however not examined in the analysis – country generation was capped at 100%.
A total of 19 governments updated their renewables expansion and/or fossil fuel phase-outs beyond the ambition of National Energy and Climate Plans – please note a previous estimate of 16 was increased to 19 to include new coal phase-out declarations.
On 01/06/2022 new policy updates from Poland and Romania were published, but were not included in the calculations due to the timing.
