At least in the Netherlands you can get a energy contract with dynamic pricing, where you pay the actual market price (plus tax) at time of use. When energy prices go negative, you'll also get paid. However, this is a knife that cuts both ways: if the energy market prices rise sharply, you'll also immediately have to pay higher prices and don't benefit from the contracting ahead-of-time and averaging that regular energy companies do. I've spoken to people with such a contract whose energy bills went up by >100x this year, compared to last year.
