A radical approach is required from government to drive the major infrastructure and system transformation needed to decarbonise the GB electricity system and provide clean power by 2030, according to a new report from the National Engineering Policy Centre (NEPC). This includes recommendations for delivering the grid, generation and system flexibility under an accelerated timescale.
Compiled by an independent working group led by the Royal Academy of Engineering and co-chaired by Dr Simon Harrison, group head of strategy at Mott MacDonald, Rapid Decarbonisation of the GB Electricity System highlights the need for government to clearly set out the value of this target as a national mission, in a similar way to the work of the vaccines task force.
The National Engineering Policy Centre report sets out six key elements required in the government’s delivery plan to achieve its clean power mission, which should be central to its Industrial Strategy:
Delivery of a highly decarbonised electricity system by 2030 will require a sharp increase in offshore wind capacity, says the report, as well as ensuring delivery of the transmission lines that are already in train, and expanding onshore wind and solar generation, particularly in places where the grid already has capacity to accept new generation. The report also advocates extending the life of the existing nuclear fleet where possible and supporting EDF to deliver Hinkley Point C as soon as possible.
Government will also need to engage with domestic and industrial electricity users to unlock the potential for demand to be shifting to the times when wind and solar generation is highest, as well as storing electricity to smooth supply through a portfolio of storage solutions.
Anticipatory investment will be key to success, says the report, with new grid infrastructure and increased distribution capacity identified as central priorities to the 2030 mission. Difficult choices will need to be made to reduce the time taken to deliver new grid infrastructure and connect power assets. This will mean confronting new transmission timelines and planning, grid connection queue delays and supply chain constraints. Adding renewable capacity in locations that can be readily accommodated without new power lines where possible and implementing a more proactive supply chain policy with clear signals to investors, are both identified as potential solutions.
Beyond 2030, the NEPC report highlights changes to a future energy system that cannot be delivered before 2030 but require action this decade. These include:
Dr Simon Harrison FREng CEng FIET FEI, co-chair of the independent working group and group head of strategy at Mott MacDonald, said:
“The scale of work required to decarbonise the electricity system in such a short period of time cannot be underestimated. But the precedent set by the rapid delivery of the Covid-19 vaccine shows that the collective pursuit of a national mission can put a seemingly impossible target within reach. A radical shift in our approach will be needed, but the engineering community has already come together to map that out in this report, and it is ready to roll up its sleeves to deliver the clean energy we need.”
Professor Sir Jim McDonald GBE FREng FRSE, president of the Royal Academy of Engineering, said:
“There is no time to waste in delivering progress towards this crucial aspect of a net zero energy system. Decarbonising our electricity under an accelerated timeline will not only provide societal benefits through an energy system that is less vulnerable to global disruption, but it also creates an opportunity for the UK to lead on the infrastructure, technology and engineering skills that will shape the future.”
