Denmark’s green energy sector is booming, but the country has hit a critical bottleneck: the electricity grid can’t keep up with demand, and the government still lacks a coherent plan for which sectors should electrify first and when.
This spring exposed a paradox at the heart of Denmark’s climate strategy. In March, Energinet froze new grid connections because the queue of companies wanting to plug in had exploded. At the same time, Denmark is racing to build massive offshore wind farms that will generate far more electricity than the country currently uses. The problem isn’t supply. It’s coordination.
I’ve watched Denmark roll out green energy policy for years now, and this feels like a turning point. The market is ready to invest billions in electrification. Heat pumps, electric vehicles, data centers, and Power to X facilities are all lining up. But without a clear roadmap for who gets connected when, and how we prioritize between competing projects, we risk gridlock in both senses of the word.
Who Gets Power First?
The current system operates on a first come, first served basis. That might sound fair, but it’s deeply inefficient. A data center that arrived early in the queue could block a district heating project that would displace thousands of tons of fossil fuel annually. Climate think tank Concito argues that Denmark needs to prioritize grid access based on societal value, not just timing.
Large scale heat pumps in district heating networks should jump the queue. So should battery storage projects that stabilize the grid. These investments directly cut fossil fuel dependence and support the broader energy transition. Data centers, by contrast, should face stricter requirements. They must generate additional renewable power and make use of their waste heat before they get a green light.
This isn’t about punishing tech companies. It’s about making choices that align short term grid capacity with long term climate goals. Right now, Denmark is making no such choices.
The Missing Electrification Plan
Denmark has ambitious targets for cutting emissions by 70 percent in 2030 and reaching climate neutrality by 2045. Electrification is the main lever to hit those targets. Yet there’s no unified government plan spelling out which sectors electrify when, how fast, and with what support.
Transport is already moving quickly. The government has set a 2030 deadline to end sales of new petrol and diesel cars, and electric vehicle adoption is climbing fast. But heating and industry are lagging. Natural gas still heats hundreds of thousands of homes, and heavy industry still burns fossil fuels for high temperature processes.
As noted by Concito, Denmark should set a firm end date for gas heating and accelerate the rollout of heat pumps and district heating. For industry, the government could fund a handful of large demonstration projects proving that electrifying high temperature processes is technically and economically viable. That would give other companies confidence to follow.
Without these plans, uncertainty freezes investment. Companies don’t know if the grid will be ready. Households don’t know if subsidies will still be available next year. Municipalities don’t know which heating solutions to approve in new developments.
Biomass and Geopolitical Risk
Denmark still burns a lot of biomass for heat and power. It was a useful bridge away from coal, but it’s neither climate neutral nor sustainable at current scales. Worse, Denmark imports much of its biomass, creating new geopolitical dependencies in an unstable world.
Concito proposes a carbon tax on biomass that reflects its real climate impact. That would improve the economics of heat pumps and speed up electrification in district heating. It would also increase electricity demand, which strengthens the business case for new offshore wind capacity. The revenue could be returned to citizens or earmarked for electrification projects if politicians prefer.
The Grid as Bottleneck
Both the transmission network run by Energinet and the local distribution grids managed by utility companies need tens of billions of kroner in upgrades over the next decade. Right now, approval processes are slow, investment frameworks are unclear, and coordination between state and municipal authorities is patchy.
Green Power Denmark and other industry groups are pushing for the grid to be built ahead of demand rather than reacting to it. That makes sense, but it requires political will and regulatory reform. It also requires accepting that large projects like data centers must meet stricter conditions if they’re going to consume scarce grid capacity.
Several municipalities have reported that grid bottlenecks are delaying green projects by years. That’s unacceptable if Denmark is serious about its 2030 deadline.
Illusions About Quick Fixes
Some voices in the debate still cling to the fantasy that nuclear power or more North Sea oil and gas can solve Denmark’s energy challenges in the short term. They can’t. New nuclear plants won’t deliver electricity to the Danish grid for 15 to 20 years. Ramping up fossil fuel production in the North Sea would have minimal impact on European energy security and would undermine the economics of green investments as electrification shrinks demand.
We know what works. More wind and solar power, which can be built now, combined with faster electrification of transport, heating, and industry. That strengthens energy independence and competitiveness within a few years. Betting on solutions that might arrive in the 2040s solves nothing today. It risks locking Denmark into continued fossil fuel dependence.
What the Next Government Must Do
Denmark’s next government faces three urgent tasks. First, give Energinet the mandate and resources to expand the grid proactively. Second, create a transparent system for
