Mapped: the £150bn megaproject that aims to protect Britain from energy shocks
The last overhaul was during the 1950s and 1960s, when high-voltage cables were rolled out at scale amid growing demand for electricity in the postwar period. Since then, major transmission upgrades have been few and far between, despite changes to how energy is generated. Bottlenecks are now common, limiting the rollout of renewables.
