Gas system Offer implementation Dispatching activities management Roles of the parties The shi hippe ppers provide gas. They nominate gas quantities at the entry and exit points, balanced on a daily basis : with adjacent operators : the entry and the exit allocated quantities are the nominated quantities ; with the final customers : the exit allocated quantities are the real consumptions. GRT RTgaz transport the gas in accordance with the shippers nominations and manages the residual balancing on an hourly and a daily basis. 9 février 2011
