In some European countries, people are paid to consume electricity. This strange phenomenon is called “negative electricity pricing.”
In summer, many households face a surge in their electricity bills due to increased use of air conditioning, fans, washing machines and other appliances. Yet in some European countries, residents are paid for their electricity consumption.
This unusual phenomenon, called “negative electricity pricing,” is spreading in Sweden, Denmark and Germany, allowing residents to earn additional income by using their washing machines or by charging their electric vehicles.
The underlying cause lies in the rise of renewable energies, notably solar power. Sunny weekends, wind and solar power production is in surplus. At the same time, power plants are closing, which reduces demand and leads to a surplus on the grid. To relieve the grid and protect it, the plants agree to compensate consumers for this surplus electricity.
Negative electricity prices are not rare in Europe. Last year, in Sweden they were negative for more than 20% of the year. In Denmark, this figure was 8% and in Germany, nearly 7%. These countries frequently record negative prices because their capacity to produce clean energy has reached a significant scale.
For example, Germany has a total solar and wind energy capacity of about 150 gigawatts. In favorable conditions, renewable energy production capacity can exceed 80 gigawatts at noon, well above the national demand during off-peak hours, which usually oscillates between 40 and 45 gigawatts.
These low, or even negative, electricity prices, caused by an increased supply, substantially optimize costs for electric vehicle users, who thus recover their electricity consumption. To take advantage of this mechanism, consumers use apps to monitor fluctuations and charge their vehicles at the lowest market price.
Previously, households’ electricity costs were generally calculated uniformly, regardless of the time of day when electricity was consumed. However, in reality, the price of electricity traded on the commercial market fluctuates constantly, hour by hour.
To address negative electricity prices caused by an excess of renewable energy, the current trend is toward building a decentralized and flexible system. The immediate solution is to deploy smart technologies allowing users to automatically recharge their devices or store electricity during peak hours in order to reduce costs and the load on the grid.
