3 ver. 1.0 page 3 from PURPOSE This Operational Procedure is based on the provisions of the Market Rules of Kosovo and provides information how the calculation of invoiced amounts of energy/losses based on Metering Data will be processed. In addition, it provides rules and descriptions how disputes of the invoiced energy amount/amount of losses should be done. Therefore, this enables KOSTT in its capacity as the MO to fulfil its responsibilities for billing of its own costs and to fulfil its duties for billing third parties as it is defined in the License for the MO issued by the Energy Regulatory Office in October 2006 and in the Market Rules. The specific terms used on this procedure are defined in a separate document Glossary of the Operational Procedures which will be submitted and published together with Procedures. The terms which are already defined in the Market Rules, Grid Code and Metering Code will not be defined in the Glossary of the Operational Procedures. 2. SCOPE This Operational Procedure provides instructions on how the Metering Data collected according the provisions of Operational Procedure T101 should be used in order to perform the invoicing as following: MO Invoices KOSTT Direct Charges and Dues, which comprise Transmission Network Support Charges, System Management Charges and the MO Charges. MO in its capacity as Billing Agent Energy Generation: o KEK Generation to KEK Supply o Ujmani to KEK Supply o Lumbardhi to KEK Supply Transmission Losses o KEK Supply to KOSTT Distribution Use of System Charges o Supplier to DSO o Eligible Costumer on its capacity as self-supplier to DSO Energy Supplied o KEK Supply to eligible customers connected to the transmission network
