Usage charges
In addition to the tariff, shippers pay usage charges. Usage charges reflect the costs incurred by Trans Adriatic Pipeline in procuring fuel gas, unaccounted for gas and electric power.
TAP’s usage charges are based on each shipper’s allocated quantities and are charged in accordance with the provisions in the TAP Network Code.
Fuel gas consumption
Each shipper with forward capacity shall pay TAP an amount in respect of fuel gas used by TAP in each gas month in which that shipper has allocated quantities for forward capacity.
The fuel gas charged to each shipper is based on TAP’s aggregate fuel gas consumption and is determined by TAP’s cost of gas and consumption at the fuel gas facilities relevant for the interconnection points for which the shipper has allocated capacity.
Shippers will not be charged for fuel gas consumption for commercial reverse capacity.
Recorded data of the fuel gas use at the fuel gas facilities for each gas day and the metered quantities of fuel gas used at each fuel gas facility is available on the TAP Electronic Data Platform (link) at the end of each gas month.
Section 14 of TAP’s Network Code details how fuel gas consumption and charges are calculated for each shipper.
Unaccounted-for gas
Shippers will be invoiced for unaccounted-for gas (UFG) for those gas months in which they have allocated quantities.
UFG represents TAP’s losses and metering inaccuracies and the positive or negative value invoiced to shippers. It is determined by TAP’s cost of gas.
Section 16 of the TAP Network Code details how UFG is calculated and allocated to each shipper.
Electric power cost
Shippers are charged an electric power cost estimate as part of the monthly payments in each Gas Transportation Agreement. TAP’s best estimate of the total costs and expenses (including taxes) expected to be incurred in each gas month up until the end of gas year 2025/2026 in relation to the purchase and generation of electric power is EUR 130,000.
TAP will annually reconcile the electric power cost estimates with the actual electric power costs for each shipper and include the resulting amount in the shipper’s annual statement.
Section 15 of the TAP Network Code details how electric power costs are calculated and allocated to each shipper.
Procurement relevant to usage charges
TAP purchases gas quantities corresponding to fuel gas consumption as well as the negative UFG, according to the procedure described in Section 14.1 (b) of the TAP Network Code.
To ensure continuity of supply, the electricity providers selected on fair market terms during the project construction phase were maintained for the initial period of TAP operation. Where local markets and contractual terms allow, TAP intends to procure electric power through a competitive tender process. A tender process was concluded in 2022 for TAP’s consumption in Greece. The procedure for future tenders for purchase of electric power will be published in due course.
