This open letter is our response to the developing uncertainty around long-term Transmission Network Use of System (TNUoS) charges, particularly concerns driven by last year’s National Grid Electricity System Operator (NGESO) 10-year projections of significant charge increases. We outline the challenges this could bring to investment decisions and consumers, and encourage NGESO to raise a code modification proposal (CMP) that aligns with the views provided in this letter, to be brought to the CUSC Panel in October 2025.
