SACH: System Adequacy of the Swiss Electricity Supply
Development of an overall concept for the system adequacy security assessment with following indicators
- Energy not Served (GWh/a) - ENS
- Loss of Load (h) - LOL
- Reserve Capacity Margin (GW) - RCM
Considering recent trends and expected developments in the electricity sector in Switzerland and Europe covering a 20-year horizon, from 2020 to 2040.
Variations in supply: assessing their impact on security of supply
- Accelerated increase in renewable energies in Switzerland ... (r)
- Early decommissioning of Nuclear Power Plants (NPP) in France ... (f)
- Coal phase-out in Germany ... (d)
- Combination of the NPP and Coal phase-out ... (fd)
Variations in demand:
- Increased electrification (accounting for electrification of heating and mobility) with an annual demand growth rate of 1.25% is assumed from 2025 on ... (s)
Network related sensitivities:
- 10-year delay in Network expansion measures ... (g)
- Net import restrictions ... (n)
Methodology
The Swiss and European electricity systems are profoundly and rapidly reshaping whilst safeguarding the security of supply:
- Supply-side: increasing decentralisation, integrating high volumes of variable renewables, phasing out of some conventional fuel-based generation sources
- Demand-side: electrification of mobility and heating
What are the consequences for security of supply?
