When wind power is abundant and spot prices are negative (which occurs in Finland about 700 hours per year, including winter) this #sandBattery takes excess electricity off the grid, stores 250 megawatt-hours (MWh) heat in hot sand, and afterwards feed 2 megawatts (MW) into the #districtHeating grid

Vaihtoehtoja tuulettomille päiville löytyy, kun etsitään. Sähkön hinnan vaihtelu ei ole ongelma vaan edellytys varastojen kehittämiselle.

Suomessa on hyviä esimerkkejä kuten #Varanto ja #SandBattery, sekä Hyvinkään kuoppavarasto.

Hinnat ovat miljoonissa, ei miljardeissa.

Die #Sandbatterie hat den Ölverbrauch beendet, den Einsatz von Biomasse verringert und die Emissionen des Fernwärmenetzes um 70 Prozent reduziert.

Das Unternehmen will auf diesem Erfolg aufbauen und arbeitet bereits an einer noch größeren Anlage.
