We have prepared and published this statement to meet its obligations as set out in Condition 30 of the SONI Transmission Licence. This requires us, in co-operation with the Republic of Ireland Transmission System Operator, prepare (and obtain the authority’s approval to) a statement setting out the basis upon which charges will be made for connection to the all-Island transmission networks.
