> I think the jury is still out whether it'll actually lead to significant energy savings. In Finland you can get an electricity contract that follows the hourly spot prices. Usually the hourly prices varies in the range from 5c to 20c/kWh, but sometimes it jumps up to 40c, even 80c/kWh. The record was 2€/kWh for a couple hours in one day. Current hourly prices for today and tomorrow: https://oomi.fi/en/electricity/electricity-contracts/active/spot-price-of-electricity/ https://oomi.fi/en/electricity/electricity-contracts/active/... People who have chosen this kind of contract, usually reduce their consumption during the ridiculously expensive hours, which usually occur when there happens both low wind energy production, and simultaneously some power plant being offline for maintenance. You can also get a contract with a fixed price, if you want.
