In mid-June, several disruptions occurred simultaneously in the regions around the border between Argentina and Uruguay, resulting in a large-scale power cut that left 48 million people without electricity. Timo Kaukonen, Manager of Operational Planning at Fingrid, answers questions about disruptions.
For the power system, summer doesn’t just mean warm and gentle breezes. We asked Operational Development Manager Jonne Jäppinen to tell us about the challenges that summer presents in terms of the electricity grid and electricity production.
One of Fingrid’s central tasks is electricity balancing, which means maintaining the balance between production and consumption. Fingrid uses fast and slow reserves for balancing, and purchases them from reserve markets. In the future, the importance of flexible resources will be even greater as production and also consumption become more variable. ”Hydropower can be regulated quickly, and that makes it a good reserve resource,” explains Expert Otso-Ville Rinne.
Everyone is talking about the electricity market transformation, but how will renewal affect the consumer? Päivi Suur-Uski is an energy efficiency expert from Motiva, and she answered our questions. Motiva Oy is a Finnish state-owned company that provides expert services to promote resource efficiency.
