Savings Calculator in Île-de-France (2026)
This hub covers 40 locations across Île-de-France, France. Electricity in this region is priced at €0.25 per kWh in our dataset — about 10% above the France average of €0.227/kWh across the 9 regions we cover. At a reference household consumption of 4,000 kWh a year that is roughly €1,000 of grid electricity annually, which is the figure any system installed here is working to displace.
