As the UK prepares for a major expansion of its electricity network, the importance of clear, consistent regulation is coming into sharp focus. New proposals from Ofgem for the RIIO-ED3 price control mark a shift toward greater stability and long-term planning; welcome news for the supply chain.

 

A key change is the move away from “boom-and-bust” investment cycles. By smoothing spending across the price control period and requiring network operators to publish demand forecasts, the proposals aim to give manufacturers greater visibility and confidence to invest. For an industry producing critical components like transformers and grid technologies, that predictability is essential. 

The stakes are high. The Climate Change Committee projects that UK electricity demand could more than double by 2050. Meeting this demand will depend on strong coordination across the sector and the confidence to scale up manufacturing capacity in the UK. 

While the direction is positive, further clarity will be key. Stronger delivery incentives and clearer guidance on issues like phasing out high-emission technologies such as SF6 would help turn ambition into action. 

With RIIO-ED3 shaping investment from 2028 to 2033, the opportunity is clear: a more resilient electricity network and a stronger UK supply chain - if the momentum is maintained.
