Flexibility of the Danish power system The dispatch of the Danish system during a week with varying wind power generation in Sep-tember 2015 is shown in figure 1.4. As a weekly average, wind and PV covered 49% and 2%, respectively of the Danish demand.
Therefore reduced flexibility of Danish large power plants tends to increase the regional CO2 emission with an amount up to about 1 million ton. This is corresponding to about 10% of the total CO2 emission from the Danish power and heat system.
The development of the capacity of Danish thermal power plants and interconnectors have changed much in the last decade as the share of VRE has risen sub-stantially.
RATIONALE AND OVERVIEW OF SCENARIOS The base case scenario (scenario 1) being the present Danish power system is characterised by having very flexible thermal power plants and a high degree of flex-ibility in balancing the system via large interconnector capacity to neighbouring countries (bidding zones).
The included storage projects in this scenario is based on the maturity of current storage projects in Denmark. Based on official data and developer communications. It is believed that Bifrost, Greensand, Gassum and Havnsø will be developed regardless of the development of a larger CCS-industry in Denmark.
The Danish consumption peak load is about 6.5 GW, minimum load is about 2.5 GW and the total yearly electricity consumption is about 33.5 TWh. Denmark is today very well connected to neighbouring countries with a total capacity of about 6,000 MW in-terconnections to Norway, Sweden and Germany (see figure 1.1 to the right).
