Flexibility Resources Finding ramping capabilities Supply flexibility Demand responds
Flexibility Resources Finding ramping capabilities Supply flexibility Sector coupling/ Electrification Demand responds
Sector coupling Electrification as source of flexibility Framework conditions Distribution of EU energy consumption (Source: EU Heating and Cooling strategy) Market design Direct regulation Fiscal policies Support schemes Grid regulation Large flexibility potentials in electrification of the energy sectors Hindered by regulatory barriers Remove barriers
District heating-electricity interface Electrification as source of flexibility Heat price Electric boilers Heat pumps Heat only boilers CHP Electricity price
Choice of heat supply - at different electricity prices Heat price Electric boilers Heat only boilers CHP Patchwork regulation between electricity and heat Taxes on electricity consumption Heat is taxed at the fuel input Biomass exempted for taxes Electricity price More heat only boilers. Decoupling of electricity and heat markets
Unlocking a decarbonised, sustainable energy future Make the sector coupling/electrification as flexible as possible Remove barriers Improve the business case for flexible power-to-heat/gas technologies Increase market integration and the value of VRE Coherent changes in market designs, regulatory framework condition, and coupling of markets www.flex4res.org Strong today - Stronger tomorrow #Flex4RES
Goals and RE-thinking of the Energy System Current electricity system The trichotomy of energy policy Decarbonised energy systems Competition Centralised fossilintensive supply Market design Sector coupling Decentralised + Variable renewable energy + Phase-out of fossil peakers Electricity market only Reliability Flexibility Sustainability System integration

Wind share in Danish annual electricity consumption Sol- og vindenergiens andel i elsystemet er vokset år efter år. 2017 sætter ny rekord med en vind- og solandel på 45,8 procent. Nedgangen i 2016 skyldes primært, at året var meget vindfattigt.
