Distribution Use of System (DUoS) charges cover the cost of building and maintaining the local distribution networks. The local District Network Operator (DNO) or Independent District Network Operator (IDNO) publish their rates each year which includes the available capacity charge which advanced Half-Hourly (HH) end consumers can find on their energy supply bills.

Transmission Network Use of System (TNUoS) charges cover the cost of installing and maintaining the transmission system. The National Energy System Operator (NESO) publishes their rates each year which includes non-locational residual charge demand tariffs. For advanced HH end consumers, this is a pass through charge within the standing charge found in energy supply bills and it is based on your maximum import capacity level.

Especially for energy end consumers with advanced HH meters, both the DUoS + TNUoS charges can be considered unfair if so much capacity does not need to be allocated for their supplies. With your permission, we can efficiently source your HH data energy usage via ElectraLink and run the data through our Energy Bucket to determine if considerable savings can be made.
