In Western Denmark, the average electricity price was DKK 0.355/kWh as opposed to DKK 0.338 in August.

Eastern Denmark (Zeeland and Bornholm) experienced stable electricity prices in September, with the average electricity price being DKK 0.36/kWh compared to DKK 0.363 in August.

In the other Scandinavian countries, the rising water levels in the water reservoirs triggered a substantial price drop, which did not affect Eastern Denmark, however, due to capacity restrictions on the Øresund Link.
