A recent report has highlighted the urgent need for a significant increase in investment in local electricity grid distribution networks in the UK. The National Infrastructure Commission's report emphasizes that with electricity demand projected to double by 2050, the current rate of investment in the country's distribution networks is insufficient to meet future needs.
According to a year-long study, a more proactive approach to planning the distribution network is essential, including addressing issues with UK smart meters and integrating smart heat pumps. However, the current regulatory framework by Ofgem is deemed overly complex and does not incentivize distribution network operators (DNOs) to make the necessary investments to enhance network capacity and resilience.
Last year, the UK's National Grid unveiled a £60 billion plan to upgrade networks in both the UK and the US over the next five years. Concurrently, the UK government is allocating £1.1 billion to reduce the time required to connect to the grid from five years to just six months.
The distribution network in the UK is vast, comprising over 838,000 km of wires, more than 230,000 substations, and 348,000 pole-mounted transformers. The report, titled "Electricity Distribution Networks: Creating Capacity for the Future," warns that failing to streamline the connection process to electricity distribution networks could hinder economic growth.
Sir John Armitt, chair of the National Infrastructure Commission, cautions, "We must learn from the UK's transmission infrastructure, where a lack of investment ahead of demand has left us playing catch-up. The risk is that without a proactive plan in place, we may end up with an overloaded and under-capacity system lacking resilience."

The report underscores the need for £37 billion to £50 billion in investment in the distribution network to accommodate future demand and generation up to 2050. This represents a substantial increase from current annual allowances for load-related expenditure, in addition to asset replacements.
Furthermore, the report suggests providing more support for supply chains by exploring new mechanisms to manage the electricity transmission supply chain within the distribution network. It recommends revising the smart meter rollout plan by 2025's end, addressing non-operational smart meters and implementing a smart appliance mandate for heat pumps in 2026.
Nick Winser, National Infrastructure Commissioner, highlights the evolving landscape of electricity generation, stating, "The days of relying on a few fossil fuel plants for electricity are over. A significant portion of our generation now connects directly to the local network, with more expected to follow in the coming decades. The future of heating and transportation is likely to be predominantly electric."
He emphasizes the necessity of a flexible and intelligent electricity distribution system to maximize the benefits of an expanding network, reduce costs for consumers, and support decarbonization efforts. Distribution networks play a crucial role in delivering electricity to homes and businesses, making them essential for a successful transition to a low-carbon economy.
Winser stresses the importance of strategic investments to empower proactive measures in distribution networks, aligning with the National Infrastructure Commission's projection of a 50% increase in electricity demand by 2035 and a doubling by 2050. As the energy system shifts towards net zero, the reliance on electricity will grow, necessitating a robust and adaptable distribution network to meet future needs.
The report also calls on the government to address the skills gap in the energy sector and take steps to attract and retain a skilled workforce essential for completing the energy transition successfully.
