Electricity in winter and its challengePower in Balance

Managing electricity poses great difficulties in both winter and summer, but what are the specific challenges in winter?

Renewables generate less

Renewable energy generation depends entirely on its environment. In winter, shorter days mean less sun, so solar power generation is lower than in summer. At the same time, our wind farms cannot generate electricity when there is no wind.

However, these changes in the level of renewable energy generation are manageable thanks to weather forecasts, which our experts receive several days in advance. This enables them to adjust the grid based on these changes in electricity generation.

We consume more

In winter, the weather is cold and the days are shorter. We turn on the heating and lights, so we consume more.

As with generation levels, this demand for electricity is analysed and predictable. Among other things, our experts study the generation and consumption curve using data from the last 40 years.

The status of our power generation facilities

Our power generation facilities comprise conventional energy sources (e.g. nuclear, gas, coal) and renewable energy sources (e.g. wind, solar, hydraulic). If we lose one unit, this affects our generation capacity. Market players work together to share power plant activity schedules and find solutions, such as importing, in a bid to maintain the balance and ensure that there is enough electricity for consumers.
