To ensure stable energy supplies and avoid bottlenecks, lost production capacity, and price fluctuations, robust energy grids and infrastructure are essential to future-proofing our energy systems.
Denmark has become a leader in this field by seamlessly integrating electricity from wind and solar, district heating and biogas. The Danish approach prioritises reliability, cost-efficiency, and sustainability, proving that green energy can also be dependable and scalable.
Danish citizens can rely on power in their sockets 99.99% of the time.
This is one of the world’s highest levels of electricity supply security.
Interconnection and renewables for a balanced grid
Even though more than 60% of Denmark’s electricity comes from wind and solar, Danish consumers enjoy electricity availability 99.99% of the time—equivalent to just 20 minutes of downtime per year.
Denmark’s interconnected electricity grid is central to its energy strategy on further segmenting its position as a net exporter of green electricity. By linking with neighbouring countries, Denmark balances supply, incorporates more green energy and ensures security of delivery.
Denmark is connected to Norway, Sweden, Germany and the Netherlands through interconnectors that stabilise the grid on both sides of the interconnector. In 2024, Denmark expanded this network with the inauguration of the world’s longest interconnector to the United Kingdom and by joining Europe’s PICASSO grid initiative.
Infrastructure for future energy systems
Building a green energy system requires more than just generating renewable electricity—it demands advanced infrastructure to store, distribute, and efficiently use energy. Denmark leads in leveraging grid-connected storage and district heating networks to optimize energy flows and reduce waste.
- Storage and electrolysis: Surplus renewable energy is stored or used for electrolysis to produce green hydrogen. This supports energy-intensive industries and transport sectors that require alternatives to direct electrification.
- District heating: Denmark’s district heating systems integrate waste heat from power plants, industrial processes and even data centers to supply affordable, energy-efficient heating to urban areas.
