The quest for growth across the UK is being hampered in places by lengthy delays to connect new developments to the electricity grid.
The worst-affected regions are the north of Scotland, East Anglia, Cornwall and Devon, West London, North Wales and the Oxford-Cambridge corridor.
This last region in particular is vital to the government’s plans for economic revival.
Chancellor Rachel Reeves unveiled new plans in 2025 to deliver the Oxford-Cambridge Growth Corridor, that will supposedly boost the UK economy by up to £78 billion by 2035.
Sir Patrick Vallance has been appointed to lead the plans. The area is a hub for globally-renowned science and technology firms, and the government believes the area has the potential to be Europe’s answer to Silicon Valley.
One major stumbling block is the fact that the area encompassing Oxford, Didcot, Bicester, Milton Keynes, Bedford and Cambridge is severely affected by grid constraints.
The DNOs that cover the region are now running a mix of reinforcement and flexibility initiatives to unblock growth.
In the Greater Cambridge area, local evidence shows grid capacity is a “significant barrier” to new labs, housing and electrification.
The report, ‘Cambridge Ahead: The Infrastructure Gap’ claimed: “The region will only be recognised as a leader in the (energy) transition if it focuses on delivering genuine, zero-emission solutions locally, rather than relying on offsetting emissions elsewhere.
“Energy infrastructure is not just about generation, transmission, storage, and distribution; it also hinges on efficiency, demand-side response, and increasingly sophisticated “smart” technologies.“
Meanwhile, last year, the Future Oxfordshire Partnership said plans to expand the town of Bicester with 7,000 new homes and a commercial zone had ground to a halt – “awaiting grid reinforcement.”
It was also reported that Milton Keynes, Swindon, Cambridge and Peterborough were reporting similar problems, with grid restrictions and connection delays constraining ability to grow the local economy.
A Smart Solution
The region has already found solutions to this bottleneck, through deploying the SNRG SmartGrid.
The £300m expansion of Harwell Science & Innovation Campus, near Didcot in Oxfordshire, has been made possible only because of the constraint-busting technology and optimisation of the SNRG SmartGrid.
The campus has signed an exclusive agreement with SNRG to design, fund and operate a private-wire SmartGrid that lets Harwell grow within existing grid limits.
The SNRG SmartGrid will avoid Harwell spending tens of millions of pounds on grid reinforcement, while delivering lower energy prices for occupiers – the price of solar energy is about 35.6% below the 2024 UK average for grid energy.
Harwell sits in one of the region’s most connection-constrained zones. SNRG’s proven campus microgrid template unlocks growth and is highly replicable for other multi-tenant sites.
Already, SNRG has come to the rescue of Bicester business Greencore Homes, with a smaller, but fast-to-replicate pattern for industrial estates.
SNRG funded and now operates a factory microgrid with rooftop solar and battery storage, delivering large bill savings and reducing peak imports.
As with Harwell up the road, landlord/tenant complexity has also been solved. The Greencore partnership includes the landlord, LondonMetric, displaying a workable legal structure for multi-party sites.
SNRG is also delivering the SmartGrid to one of the UK’s largest new towns, Otterpool Park, proving its value for large-scale residential projects.
A Booming Region – With A Blueprint For Success
There are many new large developments coming on stream in the Oxford-Cambridge corridor in the coming years, including £1.2bn innovation district Oxford North, the Houghton Regis / Chalton two-building hyperscale data centre; SWI Group “AiOnX” hyperscale data-centre campus, Cambridge Children’s Hospital Biomedical Campus, and The Oxford Science Park expansion.
There is a blueprint to speeding up grid connections, while saving money on electricity and cutting carbon.
The SNRG SmartGrid combines (mainly) rooftop solar and shared batteries, demanding a smaller import requirement from the public grid.
It can share capacity across many buildings and many tenants, instead of each tenant asking the DNO for its own cumbersome connection.
The local – and national – vision for the Oxford-Cambridge corridor to unlock vast ecominic growth, will certainly have to consider connection delays for new projects – and the SNRG SmartGrid can play a major role in accelerating ambition.
