We have written to the European Commission arguing that there is no proven need for the UK’s Capacity Market – and that as designed, it favours coal and gas power plants over cleaner technologies.
Our observations come as the European Commission is deciding whether to re-approve the Capacity Market as a State aid. It is totally inappropriate for the scheme to be approved at a time when the UK Parliament has declared a climate emergency, and when the UK’s Climate Change Committee has called for a net zero greenhouse gas emissions target by 2050.
The Capacity Market was originally approved by the European Commission in 2014 and was the first such scheme ever to receive State aid approval. It covers most of the United Kingdom, but not Northern Ireland (and so is more accurately referred to as Great Britain’s Capacity Market; for simplicity, we refer to the UK throughout this piece).
The Commission’s State aid approval was challenged in the EU courts by Tempus Energy, a ‘demand-side response’ management company. Tempus argued that the Commission had rushed through its State aid approval without properly considering whether the Capacity Market discriminated in favour of fossil fuels (gas, coal and diesel generators), and against cleaner technologies, such as storage and demand-side management.
We agree with Tempus’s arguments – the Commission only spent one month investigating this huge scheme, and did not listen to any third parties, only the arguments of the UK government.
It refused to conduct an in-depth investigation, which could have lasted up to 18 months, and would have considered the views of market players, technical experts, and civil society groups, who provide an alternative well-informed perspective.
In November 2018, the General Court found that the Commission had breached its legal requirements and annulled its decision to approve the Capacity Market. The UK government suspended its operation – and was forced to ask the Commission to re-assess whether the scheme was lawful. This time, the Court ordered the Commission to run an in-depth investigation, and open a consultation.
Capacity markets allow ‘capacity providers’ – electricity generators, demand-side management providers, and others – to bid for contracts, awarded by national government.
Under these contracts, providers commit to provide capacity in specified future ‘delivery years’. In return, these capacity providers receive huge subsidies – in the case of the UK’s Capacity Market, potentially as much as £24 billion, collectively, awarded over a period of ten years.
The theory behind the Capacity Market is that market forces alone are not enough to ensure that there is enough electricity supply at times of peak demand – and without additional incentives, there is a risk lights will go out. Capacity agreements reward operators who make electricity capacity available – and the same operators can make money by using that capacity to sell electricity to the grid. This theory is fundamentally flawed.
