It’s a bit more complex than that. Octopus do a deal where you can lease a car and get the energy for it for free provided you agree to have it plugged in > x hrs a month. My read on that is that the cost of balancing the grid is greater than the cost of generating power. So grid is expensive, but power is cheap.

Because electricity prices are tied to gas prices (not to mention that wars near countries that export gas don't help bringing prices down).
