Amber Rudd puts focus on making energy affordable and secure – but will commit to closing coal-fired stations by 2025

The energy secretary, Amber Rudd, is to “reset” Britain’s energy policy on Wednesday in a direction that downgrades tackling climate change from its highest priorities but commits to closing all traditional coal-fired plants by 2025.

In her biggest speech in the job, Rudd will say she wants policy to focus on making energy affordable and secure. She will say the aim is a “consumer-led, competition-focused energy system that has energy security at the heart of it”, and will suggest the balance has swung too far in favour of climate change policies at the expense of keeping energy affordable.
