Why TNUoS Matters
Transmission Network Use of System charges are no longer a minor pass through cost. With grid investment accelerating, these charges can materially impact budgets. Understanding how they are calculated and applied is essential for accurate forecasting and stronger financial control.
Button TextReform And Uncertainty
Charging methodologies are evolving. The move away from traditional triad structures and wider transmission investment programmes means businesses face uncertainty. Without proper modelling, you risk misaligned contracts, inaccurate accruals, and avoidable cost volatility.
Button TextContract Structure Risk
Different procurement strategies treat TNUoS differently. Some bundle estimates into fixed rates, others pass charges through at cost. Without clear visibility, it is difficult to assess value or compare supplier offers accurately.
Button TextRegional Exposure
Location still influences transmission costs. Regional demand, generation patterns, and infrastructure requirements all play a role in tariff setting. Multi site businesses often see significant variation across their estate.
Button TextBoard Level Impact
Finance teams increasingly expect transparency on non commodity costs. TNUoS volatility can distort budgets, forecasts, and carbon strategies. Clear reporting and proactive planning protect credibility at board level.
