EQ hydrology forecasts show inflow to Norwegian reservoirs will average  180% of normal levels over the coming two weeks, as higher temperatures accelerate the spring melt.

The combined snow and groundwater levels in Norway reached a year-high of 200% ofthe normal level by week 21. EQ’s forecasts predict around 10 TWh spillage because of the rapid spring melt and exceptionally high snow and groundwater levels:

EQ expects the Norwegian reservoirs will hit max capacity by mid-July (week 29/30):

“During the forecast flooding situation in mid-June, we estimate 1-2 TWh of spilled water, while the second wave, when reservoirs are full, will be more severe,” says EQ’s hydrologist Eylert Ellefsen.

“Wet conditions in July and August may cause severe flooding damage along several watercourses. We estimate 8-9 TWh spilled water in August given normal precipitation.”

EQ continually updates our hydrology forecasts for the entire Europen hydropower system.

This April has seen a notably cold spell of weather sweep across Europe. Temperatures have been 4 or 5 degrees Celsius below normal in most areas, whilst spot prices for the past month have delivered 5-7 €/MWh higher than expected in several areas. In this blog post, we study how the Central Western European (CWE) hydropower system developed during this cold spell and compared this situation to available historical statistics.
