Denmark

Key facts

Denmark produces 35 317 GWh of electricity and imports 12% of their total electricity consumption. [1]

Denmark is 21% electrified.

In June 2021, the Danish Government published its overarching electrification strategy, “Elektrificering af samfundet – Vejen mod det elektriske Danmark” (Electrification of Society – The Path Towards Electric Denmark). [2]

 

The Danish electricity to gas price ratio is around 2 for industry and 2.5 for households. [3]

The Danish electricity mix is composed of
  • Wind
  • Biofuels
  • Solar PV
  • Coal
  • Waste
  • Natural Gas
  • Hydropower

Current state of electrification

Residential buildings in Denmark

Buildings

  • Buildings consume a massive 63% of the national electricity consumption with 32% for the residential sector and 31% for the commercial and public services [4]
  • There are approximately 675,500 individual heat pumps installed in Danish homes and buildings. This represents a significant expansion, having roughly doubled since 2020 as the country phases out older fossil fuel boilers. [5]
  • Roughly 65% of Danish households are connected to district heating. Heat pumps are predominantly deployed in areas outside the district heating grid to replace fossil-fuel boilers (gas and oil). [6]

Industry

Grid and flexibility

Transmission & Distribution

Denmark’s transmission system operator, Energinet, suspended all new grid connections in March 2026. This freeze was due to a project backlog of around 60 GW in the queue, which is nearly ten times Denmark’s peak electricity demand of approximately 7 GW.
The pause was lifted in June 2026 following a overhaul of connection rules, replacing ‘first-come, first-served’ with a pool-based framework evaluating project maturity and grid-friendliness.
In 2025, applications for an additional 28,400 MW of connection capacity were filed [13]

Storage

Denmark anchored its grid stability on robust subsea interconnectors linking to the Swedish, Norwegian, and German markets instead of domestic storage.
Nevertheless, the recent emergence of grid congestion and frequent negative pricing events has sparked an unprecedented surge in the rollout of utility-scale battery energy storage systems reaching approximately 150-250+ MW of front-of-the-meter battery storage. [14]
By far the largest total battery capacity physically located on Danish territory sits inside Electric Vehicles. Denmark has almost 600 000 electric vehicles (BEVs) on the road. With an average battery pack size of roughly 60-75 kWh per car, the mobile battery capacity of the Danish fleet exceeds 20-25 GWh. [15]

Smart meters

Denmark has a 100% coverage of smart meters, and households are all equipped with smart meters capable of recording consumption data every 15 minutes. [16]

Support schemes

Targets

Buildings

  • Denmark set a national goal to completely phase out natural gas for individual space heating by 2030. All 400,000+ gas-heated homes are required to transition either to direct electrification (heat pumps) or district heating.
  • Denmark aims for 100% green/fossil-free district heating by 2030. To achieve this without relying solely on biomass, the Danish Energy Agency set explicit goals to install massive industrial heat pumps and electric boilers into district heating grids. [24]

Transport

  • 1 Million Zero-Emission Vehicles by 2030 (national): Under the Agreement on Green Transition of Road Transport, Denmark established an explicit target to reach at least 775,000 to 1,000,000 zero-emission cars (BEVs and FCVs) on Danish roads by 2030.
  • Denmark set a national political ambition to end the sale of new petrol and diesel cars by 2030, aligning with the EU-wide zero-emission mandate for all new cars and vans by 2035 (EU CO₂ standards). [25]

Industry

  • Denmark’s sector roadmap mandates that industry and transport cut their fossil fuel consumption in half by 2030 compared to baseline levels. Because up to 92% of Danish industrial process heat can technically be electrified (mainly via high-temperature industrial heat pumps under 200°C), electrification is the primary lever to meet this target. [26]

Gaps and Challenges

Heating transition friction outside district networks: While 65% of Danish homes leverage district heating, the remaining 35% rely on individual solutions. Despite 675,500 heat pumps being installed, replacing the remaining 400,000+ individual natural gas boilers by 2030 requires navigating localised grid constraints, consumer upfront cost friction, and complex zoning boundaries between individual heat pump deployment and collective district heating expansions.

Low overall electrification rate (21%): Despite producing highly decarbonized electricity (86.8% from wind, solar, and biofuels), electricity accounts for only 21% of Denmark’s total final energy consumption. Expanding direct electrification into heavy freight, high-temperature industrial heat, and maritime transport remains a primary hurdle.

Absence of direct EV purchase subsidies: Denmark relies on registration tax reductions (Registreringsafgift) and electricity tax waivers rather than direct purchase grants for private EV buyers. While corporate fleets and middle-to-high-income private buyers benefit, lower-income market segments face higher upfront barriers for new zero-emission vehicles.

Assessment

Buildings

On track

Buildings account for 63% of national electricity consumption. Heat pump deployment has roughly doubled since 2020. The 2030 target to phase out individual gas space heating is well-supported by a dominant, rapidly electrifying district heating network (65% household coverage).

Transport

On track

Although transport currently accounts for only 3.2% of electricity demand, EV deployment is scaling rapidly. Strong registration tax phase-ins, charging pool grants for apartment buildings, and reduced charging taxes position Denmark well to reach its 2030 goal of 775,000–1,000,000 zero-emission vehicles.

Industry

At risk

While up to 92% of industrial process heat below 200°C can technically be electrified, cutting industrial fossil fuel use by 50% by 2030 hinges heavily on how quickly manufacturing facilities can deploy industrial heat pumps under escalating CO₂ tax rates without running into severe grid connection bottlenecks.

Power system

On track

Denmark’s electricity generation is highly decarbonized, powered by 58.2% wind, 10.7% solar PV, and 17.9% biofuels. The power system benefits from high interconnection capacity with neighboring markets (Sweden, Norway, Germany) and a growing utility-scale battery pipeline (150–250+ MW / 400–600+ MWh) supplemented by over 20–25 GWh of mobile EV battery capacity.

Grids

Lacking

Denmark boasts 100% smart meter coverage with 15-minute resolution data, providing excellent distribution visibility and demand-side potential. However, the system faces a critical bottleneck: Energinet’s 60 GW connection queue freeze has exposed severe transmission-level constraints, forcing a complete overhaul of connection rules.

Policy framework

On track

Denmark features one of Europe’s most coherent electrification frameworks, anchored by the national “Elektrificering af samfundet” strategy, the Green Tax Reform, and targeted financial pools (Erhvervspuljen, Fjernvarmepuljen). Policy design is comprehensive across all sectors, though its ultimate success depends on resolving grid connection queues and accelerating infrastructure builds.
