Growing the grid

摘要

Rerouting power transmission at bottlenecks in the UK grid has helped free up 1.5GW of capacity and save ￡380m.

As large, centralised thermal generation from fossil fuels and legacy nuclear plants is phased out, increasing amounts of distributed and intermittent renewables are coming online, posing challenges for transmission across the grid.
