In the UK the wholesale price was about £80/MWh in 2025. The retail price was about £270/MWh + a standing charge. If you factor in the standing charge, an average user paid about £344/MWh. So the cost of generation was only about 23% of the retail price. I believe the green levies + CfDs accounted for about another 15% of the retail price.

Does this mean that if generation was free, and there were no green policy costs, our electric would still be expensive?

edit: "Network and Distribution" appears to contribute about 23% of the retail price. I guess green energy increased that cost because wind/solar are more spread out and sometimes off-shore.

Transmission is pretty expensive, lots of infrastructure and maintenance.

Also distribution is handled by private monopolies.
