Draft Electricity Capacity Mechanism (Amendment) Regulations 2024

What happened: On 15 January 2025, the House of Commons voted to approve the Draft Electricity Capacity Mechanism (Amendment) Regulations 2024, passing by 418 votes to 78. The regulations update the rules governing the UK's electricity capacity market, a system designed to ensure there is always sufficient power generation available to meet demand during peak periods.

Why it matters: The capacity market works by paying electricity generators to guarantee they will be available to supply power when the grid needs it most, reducing the risk of blackouts or supply shortfalls. These amendments update the mechanism's rules, with the stated aims of maintaining energy security and better integrating renewable energy sources into the system. The changes affect electricity generators, energy suppliers, and ultimately consumers, since the costs of the capacity market are recovered through energy bills.

The politics: The vote split largely along party lines. All 311 Labour MPs and 37 Labour and Co-operative MPs voted in favour, alongside all voting Liberal Democrats, Plaid Cymru members, and the Green Party. The opposition came primarily from the Conservative benches, where 64 of 116 voting or absent MPs voted against, joined by all six voting Reform UK MPs and all five voting Democratic Unionist Party members. One Conservative MP broke ranks to vote with the government. The vote reflects a broader pattern in this Parliament, where the Labour government has consistently pursued energy security and net-zero legislation with opposition concentrated among Conservative and right-leaning parties.
