Flexible Urban Networks – Low Voltage

Efforts to decarbonise energy generation and heat and transport will place increasing demands on distribution networks, particularly so for the low voltage (LV) networks closest to our customers, where DNOs have the obligation of supplying customers their electricity demand, within tightly defined voltage limits which their consumer electronics have been designed to expect, and at a sufficient quality (harmonics, sags, swells and flicker). Analysis carried out by Imperial College to support our RIIO-ED1 business plan predicted an increasing trend of voltage issues and demand rises that could overload transformers and underground cables, requiring £132.6m of network reinforcement during the RIIO-ED1 period if reinforced by conventional means.
