EUSEW Energy Day: Climate forecasts for renewable energy

webinar series

S2S4E is organising an EUSEW Energy Day on 8 June with a series of three webinars on climate uncertainty visualisation, forecasts for the summer season and the Nordic energy market.

The EU Sustainable Energy Week (EUSEW) is the biggest event dedicated to renewables and efficient energy use in Europe. The 15th edition of EUSEW will be held as a digital event on 22-26 June 2020, bringing together energy stakeholders and enthusiasts to discuss and debate the way forward for green recovery and growth.

Better forecasts could have prevented losses for Swedish hydropower in 2015

Factsheet 4

Very wet weather in Sweden in summer 2015 caused power prices to plunge. The resulting losses for hydropower operators could have been reduced if they had used seasonal forecasts in their decision-making, a study by S2S4E shows.

In the period May-July 2015, precipitation levels in Sweden were well above normal for the time of year, with the rain filling up the country’s hydropower reservoirs. At the same time, it was also unseasonably cold, causing snow melting to occur slower and later than expected

Better forecasts can reduce dependency on fossil fuels

Albert Soret

Better forecasts for clean energy production and power demand can improve the integration of renewables into the electricity system and help reduce the use of fossil fuel-fired plants, says Albert Soret, the leader of the S2S4E project.

“Both energy production and demand are strongly affected by weather conditions and their evolution over time. That is why we are working to make climate predictions more reliable and understandable,” Soret says in the video below.

Vattenfall: “Water is the fuel for our hydropower stations, so forecasts are very important”

Mikael Sundby

For Swedish energy company Vattenfall, which owns many wind and hydropower plants in several countries in Europe, weather forecasts are very important as they increase the accuracy of their own electricity production forecasts. 

According to Mikael Sundby, a hydrologist and planner of hydropower production at the Swedish utility, the more Vattenfall invests in developing new renewable energy, the more important it becomes for them to have access to reliable forecasts.
