Although 65% are aware of negative Danish electricity prices – when electricity costs less than 0 DKK per kilowatt-hour—one in three fails to take advantage of the opportunity to save money by shifting their power usage to these low-cost periods.
Many Miss Out on Cheaper Electricity Despite Growing Awareness
New data from an energy usage study conducted by YouGov on behalf of Danish energy and advisory company NRGi reveals a surprising gap between awareness and action when it comes to saving on electricity. Although a majority of Danish consumers—65%—say they understand the concept of negative Danish electricity prices, only just over half of them make consistent efforts to modify their usage during these low-price hours. It suggests there is still a big difference between knowing and doing.

The survey shows that 31% of those who are familiar with the phenomenon have never changed their consumption habits to align with hours of negative pricing. Another 7% admitted to trying it only once. This means that nearly four out of ten Danes are not taking full advantage of a cost-saving change that requires minimal adjustment to daily routines. Experts say this means a lot of savings are lost.
Negative electricity prices occur when electricity supply—particularly from renewable sources like wind and solar—exceeds demand. In such situations, certain power producers are willing to pay users to consume electricity, resulting in prices below 0 DKK/kWh. This phenomenon is increasingly common in Denmark, thanks to the country’s large investments in green energy.
2025 On Track to Break Records for Negative Pricing Hours
So far, 2025 is shaping up to be a record-breaking year in terms of the number of hours with negative Danish electricity prices. As of mid-September, Western Denmark (DK1) has already experienced 397 hours of negative pricing, surpassing the 375-hour record set in 2024. Eastern Denmark (DK2) has seen 245 such hours so far, trailing just behind last year’s 275 hours.
These periods primarily occur during times of high wind or solar energy generation when the grid becomes overloaded, particularly during nights and weekends when overall electricity consumption is lower. Denmark’s grid is divided into two major price zones—Western and Eastern Denmark—so these negative prices can occur independently in each zone.
Despite the potential savings, many consumers continue to miss these opportunities, mainly due to lack of planning or not having a utility contract that allows hourly billing.
Small Adjustments, Big Savings
One reason more Danes aren’t adjusting their usage is the assumption that saving money requires a major lifestyle change. In reality, shifting just a few high-consumption tasks—such as running washing machines, dishwashers, or charging an electric vehicle—to cheaper hours can result in noticeable savings.
Additionally, understanding one’s electricity billing structure can make a major difference. Only customers with electricity plans that reflect hourly spot market pricing will benefit directly from these Danish electricity prices. Others may be on flat-rate plans that do not fluctuate throughout the day.
Lower Electricity Taxes Expected to Boost Flexibility
NRGi also highlights an upcoming reduction in Denmark’s electricity tax as a potential catalyst for increased participation among consumers. Starting January 1 and lasting for two years, the electricity tax will be reduced to the European Union’s minimum level. This tax cut will bring the total cost that consumers pay closer to the actual market rate and enhance transparency.

This simplified pricing model makes it easier for consumers to identify when Danish electricity prices are cheapest and helps households make informed decisions about when to run major appliances. It also aligns with broader national goals, such as accelerating the shift to green energy and balancing loads across the increasingly electrified grid infrastructure.
Environmental Benefits Beyond Cost Savings
Beyond household budgets, the push for more flexible electricity usage contributes significantly to Denmark’s ongoing green transition. Aligning electricity use with periods of high renewable energy supply reduces waste, lowers carbon emissions, and relieves pressure on the power grid during peak times.
In the long term, these practices not only lower energy bills but also support national sustainability goals. With energy demand expected to rise sharply due to increasing electrification in sectors like transportation and heating, smarter consumption patterns will play a crucial role in ensuring a stable, eco-friendly energy system.
Understanding Consumer Behavior is Key
According to the YouGov survey of over 1,000 respondents, 58% of those aware of negative pricing have already altered their electricity use multiple times to take advantage of these discounts. Another 8% say they are considering making the change, signaling growing momentum.
However, the survey also makes it clear that more public information, better utility billing transparency, and small behavioral nudges could significantly boost the number of people actively optimizing their electricity usage.
As Denmark continues to lead the way in green energy adoption, bridging the gap between awareness and action will be essential—not just for individual consumers, but for the nation’s energy future.
