The price of electricity in Finland is facing potential increases as the annual maintenance of the Olkiluoto 3 nuclear power plant begins, coinciding with generally colder weather. Vihreä Älyenergia reports that the Olkiluoto 3 maintenance will put pressure on wholesale electricity prices. Low wind conditions later this week could cause significant price spikes during peak consumption hours in the mornings and evenings. However, windy weather may keep prices lower, even with reduced nuclear power generation. The company’s announcement suggests that the cheapest times of the week will likely be during nighttime and midday hours. The extended downtime of Olkiluoto 3 is expected to have a substantial impact on the Finnish energy market.
