System perspectives for the 70% greenhouse gas reduction target and large-scale offshore wind

System perspective analysis for achieving the 70% reduction target by 2030 and enabling long-term large-scale utilisation of the Danish offshore wind potential.

Energinets’ analysis 'System perspectives for the 70% target and large-scale offshore wind’ examines how the energy system can, in the longer term, support climate neutrality and the effective integration and utilisation of Danish large-scale offshore wind power, where the 70% greenhouse gas reduction target in 2030 is a natural milestone along the way.

The analysis outlines several examples of possible long-term development paths for the energy system and is an important contribution to the planning and development of the electricity system for Energinet Electricity System Operator. The analysis focuses on infrastructure and system solutions which support a cost-effective utilisation of the Danish wind energy potential – especially in the North Sea – and in the long term a climate-neutral energy system.

The analysis includes the following three elements:

  • A focus analysis with examples of possible development pathways for a Danish energy system that fulfils the 70% reduction target in 2030 (Part 1)
  • A long-term system analysis, which shows the perspectives of utilising large-scale offshore wind power in 2035 (Part 2)
  • A summary of selected development areas for the electricity transmission system operator in relation to the 70% reduction target, the utilisation of large-scale offshore wind power and the long-term planning and development of the electricity system (Part 3).

Energinets’ system perspective analysis shows that PtX and sector coupling with gas, incl. hydrogen areimportant for the efficient utilisation of the major Danish offshore wind resources. With effective system development in this area, Denmark can utilise the very large Danish offshore wind resources for electricity exports when the international market price is high and production elsewhere is low, whereas production while the electricity production is high and low market value can be refined into high-value PtX fuels which can replace fossil energy consumption. The value of the Danish wind power will therefore be maximised, and the Danish part of the North Sea can ensure significant climate gas reductions both in a national and international perspective.

With the analysis 'System perspectives for the 70% target and large-scale offshore wind', Energinet wants to bring some significant development perspectives into the discussion of the future development of the energy system – both in relation to the 70% objective, but in particular also in relation to the development of the electricity and gas systems which may be necessary to maximise the value of the Danish renewable energy resources.
