Overview
- British Gas owner Centrica projects that by 2030 electricity will cost more than at the height of the Russia‑Ukraine energy shock.
- Chief executive Chris O’Shea says only about one third of 2030 bills would come from wholesale power, with the remainder driven by system costs.
- Reported estimates point to roughly £90bn for high‑voltage transmission upgrades and £22bn for distribution works through 2031.
- O’Shea argues these system costs reflect years of underinvestment rather than net zero policies and would be required under any pathway.
- NESO chief Fintan Slye warns fast‑growing data centre demand could raise prices and strain supply if poorly sited, as Ofgem’s cap stands at £1,758 and industry reports show household energy debt nearing £5bn.
