Transmission Network Use of System charges forecast

Transmission Network Use of System charges forecast

As the GB networks change to incorporate the rapid build out of low-carbon technologies, understanding network charges is becoming critical to assessing business cases for new and existing projects, especially in assessing locational decisions and impacts.

Cornwall Insight’s ‘Transmission Network Use of System charges (TNUoS) forecast’ is designed to help generators, developers and existing asset-owners with a long-term 15-year view of generator TNUoS charges by region. We provide invaluable insight into how charges may develop and what impact this could have on your assets.


The TNUoS forecast, updated twice a year, provides a long-term forecast of expected costs and revenues from TNUoS charging.  Through our independent power market modelling we also assess key drivers such as regulatory modifications and the generation mix.

The report provides subscribers with the ability to understand the trajectory of TNUoS costs and revenues beyond the horizon of current public forecasts, allowing you to integrate these into budgets and business plans.

The forecast builds on our long-standing work creating bespoke TNUoS forecasts for generator business cases, due diligence and cost assessments with these expert views and modelling capabilities incorporated into the service.
