It's also widely misunderstood. Just because the spot price of electricity is set by the price of gas doesn’t mean the consumer pays that price for all of their electricity.

A lot of wind and solar are on Contracts for Difference. That means when market prices go above the agreed level, the generator pays the difference back through the scheme, which reduces supplier costs rather than the generator simply keeping the whole windfall.

This is particularly relevant when e.g. the price of gas goes way up due to the Iran war, it doesn't mean that the consumer ends up paying more for the energy from wind
