Under the Uniform Network Code (UNC), shippers are incentivised to balance their system inputs and outputs and make accurate nominations using the Gemini system.

Financial energy balancing charges, invoiced by Correla on behalf of Xoserve, may be incurred if shippers are unable to balance their portfolio by the end of the gas day.
