Market price is always up to date
Hehku Spot is an electricity contract that follows the electricity market price (so called spot price). The price per kWh varies hourly according to the current market price in the Nord Pool electricity exchange and it sets the hourly price for the Finnish market.
With this contract type, you can optimize your electricity consuption and benefit from the low market prices. The downside is the risk of price volatility. While prices can drop low, they can also climb high.
With Hehku Spot, you don't commit to long contract terms. You can terminate the contract with a 14-day notice.
