YEARLY FIRM CAPACITY PRODUCTS ALLOCATION PROCEDURE ON THE REGIONAL BOOKING PLATFORM FOR GAS YEAR 1 OCTOBER 2017 – 1 OCTOBER 2018

Dear partners,

We would like to inform you that regarding obligations under Regulation (EU) No 984/2013 establishing a Network Code on Capacity Allocation Mechanisms in Gas Transmission Systems Bulgartransgaz EAD will hold a yearly firm capacity products allocation procedure for gas year 2017-2018 on the Reginal Booking Platform in line with ENTSOG standard auction calendar on 06.03.2017, 10.00 am local time (07.00 UTC summer time; 08.00 UTC winter time).

The capacity products for gas year 2017 – 2018 for the interconnection points that will be offered in the procedure on 06.03.2017 are as follows:

Recalculation of capacity from volume into energy value is based on 1-year historical data on natural gas gross calorific value at reference temperature of 25^оС ;1 cu m = 10,64 kWh

If the neighboring EU member states TSOs announce bundled capacity products the bundled capacity products announce by Bulgartransgaz EAD shall undergo a capacity bundling procedure when an auction on the platform is announced. When buying capacity the platform user shall get entry and exit capacity on both sides of the interconnection points.

Failing to provide bundling of firm capacity products on the Platform, such products shall be offered as unbundled capacity products (ensuring capacity at the respective interconnection point at Bulgartransgaz EAD network only).

In this respect we would like to draw your attention on the offering of bundled year capacity at IP Kulata/Sidirokastro in reverse flow direction, transfer point between the two networks, respectively.

Currently no capacity bundling has been envisaged for the IPs with the Romanian operator due to VTP lack in the Romanian networks.

Existing and potential network users shall be informed that the application and capacity allocation both for IPs and domestic points of the system shall be made via the Regional Capacity Booking Platform (RBP) where a user registration is required.

Information on how to register on the RBP is available here.

More information on the RBP and the applicable documents on its use is available here:

- Network User Membership Agreement;

- RBP Operational Rules.

Granting access to the gas transmission networks owned by Bulgartransgaz EAD shall be made in line with the procedures and terms and conditions of the Rules for access to the gas transmission and/or gas distribution networks and the natural gas storage facilities effective as of 27 December, 2016.

Information on the financial terms and conditions in line with art. 10b, para.6 of the Rules for access to the gas transmission and/or gas distribution networks and the natural gas storage facilities effective as of 27 December, 2016 shall be published in addition.
