Wires, Wait Times and the Village Grid: Rural Devon and Somerset’s Energy Gap

Rural Devon and Somerset are often described as places of green opportunity. They have roofspace, land, farm businesses and community groups keen to reduce energy costs. Yet the transition is being held back by something less visible than planning disputes or public opposition: the capacity of the electricity grid.
In 2026, the problem is both physical and procedural. Parts of the distribution network were designed for a world of one-way power flows, from transmission down to homes and farms. They were not designed for rooftop solar, battery storage, heat pumps and electric vehicle charging all pushing and pulling power at the same time. As demand for connections grows, projects queue for upgrades that can take years and cost far more than the generation schemes themselves.
The queue behind the wires
The connection queue is now a familiar issue across the UK, but its effects are particularly acute in rural areas. A farm seeking to install a larger solar array may be told that the local substation has no capacity. A housing development may be delayed by the need for reinforcement. A community energy group may find that its battery project is technically feasible but commercially unviable once connection costs are included.
The South West’s geography compounds the challenge. Long feeders, scattered settlements and a relatively thin network mean that upgrades are expensive per household. In parts of Exmoor, the Somerset Levels, Mid Devon and North Devon, the cost of reinforcing the grid can dwarf the value of the low-carbon generation that prompted the request.
Ofgem’s 2026 reforms are intended to address some of these problems. Changes to connection queue management, greater emphasis on projects that are ready to proceed, and moves towards more flexible connections could reduce waiting times. Strategic investment and local area energy planning may also help networks anticipate demand rather than react to it. But the reforms are not a silver bullet. They will take time to bed in, and they will not remove the fundamental cost of upgrading rural infrastructure.
Why rural areas are hit hardest
The energy transition is often framed as a national project, but its practical delivery is intensely local. Rural homes are more likely to rely on oil or electricity for heating, and farms face volatile energy costs for grain drying, cold storage, irrigation and machinery. Electrification can reduce emissions and exposure to fuel price shocks, but only if the grid can support it.
There is also a land-use dimension. Devon and Somerset have seen interest in solar farms, battery storage and anaerobic digestion, all of which require connections. Some proposals are welcomed for income diversification; others raise concerns about landscape, food production and local consent. The grid bottleneck does not resolve those debates. It simply adds another layer of delay and uncertainty.
Community energy groups have responded with ingenuity. Microgrids, shared battery storage and behind-the-meter schemes can allow villages, farms and businesses to make better use of local generation without waiting for a major network upgrade. A village hall with solar panels and a battery may be able to store excess power and reduce evening imports. A farm may combine generation with storage to manage peak costs. These are practical steps, but they are not a substitute for strategic grid investment.
The limits of local self-reliance
Microgrids and batteries can improve resilience and reduce bills, but they face their own constraints. Capital costs are significant, insurance and maintenance need to be planned for, and the regulatory framework for selling or sharing power is complex. Community groups often rely on volunteers and grant funding, which makes long-term operation difficult.
There is also a risk of creating a two-tier transition. Wealthier households and well-organised communities may be able to invest in local energy solutions, while others remain dependent on an ageing network and rising bills. If rural Devon and Somerset are to turn green innovation into affordable power for all, local schemes need to be linked to a wider plan for network investment and consumer protection.
What 2026 could change
The test of Ofgem’s reforms will be whether they make the connection process faster, clearer and fairer. Rural projects need transparent queue information, realistic timelines and a way to connect flexibly where full capacity is not immediately available. Local authorities can help by aligning planning and energy planning, so that new development does not add demand without considering supply.
None of this will happen quickly. Grid reinforcement is expensive, and the South West competes for investment with other regions. But the alternative is a prolonged waiting game in which rural communities are told that the energy transition is coming while their connection dates slip further away.
The region’s green ambition is real. The question for 2026 is whether the wires, substations and governance can catch up with it. Without that, rural Devon and Somerset will remain a test case for the gap between local energy innovation and the infrastructure needed to make it work at scale.
