I. Justification of Bulgartransgaz EAD expansion projects I.1. Introduction Bulgartransgaz EAD is an operator performing licensed activities of natural gas transmission (Transmission System Operator, TSO) Bulgartransgaz EAD operates and develops gas transmission infrastructure in country, which currently consist of two gas transmission networks and an underground gas storage facility: National gas transmission network (NGTN) - gas transmission network with main function natural gas transport to users in Bulgaria who have connected to network. It is built of approximately 1835 km high pressure main gas pipelines and high pressure gas branches and three compressor stations with total installed capacity of 49 MW. The technical transport capacity of network amounts to 7.4 bcm/year, and maximum working pressure is 54 bar. Gas transmission network for transit transmission (GTNTT) - gas transmission network with main function transit transmission of natural gas as well as natural gas transport to connected users in Bulgaria. It consists of 930 km gas pipelines and six compressor stations with a total installed capacity of 270 МW. Mainly natural gas quantities from an entry point at Bulgarian-Romanian border to exit points to Turkey, Greece and Macedonia are transported through network. The technical transit transmission capacity of network amounts to 17.8 bcm/year, and maximum working pressure is 54 bar. Underground Gas Storage (UGS) Chiren is built in lands of Chiren village on a base of depleted gas condensate field of same name. Chiren UGS has 23 exploitation wells and a compressor station with a total installed capacity of 10 MW. The current storage capacity can provide storage of 550 mcm of natural gas. The commercial withdrawal capacity is up to 3.4 mcm/day, and injection capacity is up to 3.16 mcm/day. The favourable geographical location of our country represents a natural route where natural gas flows entering from different sources and routes can be directed/allocated to different directions, depending on market interest and price signals. I.2. Long-term forecasts and plans Pursuant to Article 170(4) of Energy Act of Republic of Bulgaria, TSOs are obliged to develop natural gas transmission system in country in compliance with long-term forecasts and plans for development of gas supply and outside m when it is economically justified. Bulgartransgaz EAD annually prepares National Ten-Year Network Development Plan (NTYNDP) and takes an active part in development of European Ten-Year Network Development Plan (TYNDP) within its membership in European Network of Transmission System Operators for Gas (ENTSOG). The results of se TYNDPs show that re is a trend of
increasing consumption in Bulgaria, countries neighbouring Bulgaria as well as in countries of Central and Eastern Europe (CEE). Diagram 1 shows consumption forecast at blue transition scenario part of TYNDP based on data of TSOs in EU, a scenario which is most likely to come true in region of Bulgaria and in CEE, as well as expected level of local production and necessary import in EU to cover consumption/ local production difference: Diagram 1 The forecasts prepared by TSOs in EU and ENTSOG show a tendency where local production decreases and consumption in certain EU MS increases. While local production is expected to decrease from 1 260 TWh/y to 720 TWh/y, consumption grows with approximately 11% - from 4 770 TWh/y to 5 300 TWh/y. This results in need to import 1 000 TWh/y additionally from third countries to EU compared to 2017 (which is about 90 bcm/y). The map 1 below shows expected increasing trends in natural gas demand up to 2035: 1 The data is taken from ENTSOG s TYNDP.
Legend: Demand increase in percentage (Δ) by countries: +0% +50% < +100% +0% < +50% > +100% Balkan countries (Bosnia and Herzegovina, Bulgaria, Croatia, Greece, Kosovo, Macedonia, Romania and Serbia (no data for Albania and Montenegro) get 222 TWh/y (37%) of additional demand in EU. 85% (188 TWh/y) of it is from Bulgaria and countries neighbouring Bulgaria Greece, Macedonia, Romania and Serbia 1. In addition, natural gas demand from Turkey and Macedonia is expected to increase with more than 180 TWh/y (about 16 bcm/y) over period. 2 I.3. Connection to significant market zones The favourable geographical location of country is a natural connection for natural gas supply and transport between markets of member-states in region Bulgaria, Greece, Romania, Hungary, Croatia, Slovenia, member states of Central and Western Europe (including Austria) and Energy Community countries - Serbia, Macedonia, Bosnia and 2 The data is from Bulgartransgaz s TYNDP
Herzegovina, etc. Bulgaria is also in an excellent geographical position to be a connecting unit for supply and transmission from/ to, which is largest natural gas consumer in South-Eastern Europe. Turkey's consumption in 2015 amounts to 43.6 bcm/year (480 TWh/y) and is expected to reach up to 59 bcm/y (650 TWh/y) by 2020. BOTAS, Turkish TSO plans in next years to increase daily capacity of Turkish gas transmission system to more than 350 mcm/d against current 200 mcm/d 3. I.4. Synergy with or projects in country and region The development and expansion projects of existing gas transmission system on territory of Republic of Bulgaria are in line with project for modernization and rehabilitation of existing gas transmission system in Bulgaria (PCI 6.8.2) and Balkan Gas Hub project (PCI 6.25.4). Development and expansion of existing gas transmission system on territory of Republic of Bulgaria toger with current Bulgarian and regional projects, part of strategic infrastructure of projects of common interest (PCI), will conceptually contribute to construction of a new gas transmission infrastructure for gas supply to markets of Member States in region of South-Eastern and Central Europe, as well as to countries of Energy Community, such as Serbia. 3 Data sourced from Bulgartransgaz EAD TYNDP
II. Results from Open Season Phase I To prepare an updated assessment of market incremental capacity demand and identifying required new projects to satisfy demand in period 21 July 2017 21 August 2017 Bulgartransgaz EAD assessed non-binding capacity demand indications by potential and existing network users as part of Phase I of Open Season. Market testing represents part of overall process of assessing project viability, which in turn is one of elements accompanying future investment proposal to NRA. At time of preparing such assessment Bulgartransgaz EAD used for a basis good practices for assessment of market demand for incremental capacity laid down in article 26 of Regulation 2017/459 establishing a network code on capacity allocation mechanisms, including elements from ENTSOG developed template for non-binding demand forecast.

No new project is refore currently required within this Open Season. The residual capacity up to nonbinding nomination will be enabled with congestion management procedures and/or capacity offer at interruption conditions. The potential projects enabling, if needed, entry capacity from Romania which will be assessed by end of 2018 are in pre-investment phase.
III. Project for incremental capacity Expansion of gas transmission infrastructure in section from Bulgarian- Turkish border to Bulgarian-Serbian border With a view to realizing expected incremental capacity from Turkey (entry) to Serbia (exit) as a result of conducted feasibility (pre-investment) studies, following new and currently existing infrastructure (See model scheme) is expected to be used: The entry point is on Bulgarian-Turkish border immediately next to existing interconnection between gas transmission network for transit transmission of Bulgarian operator and gas transmission network operated by BOTAS (Turkey). The direction of physical gas flow is to CS Provadia and Serbia, and exit point is on Bulgarian-Serbian border next to Zaychar. The maximum natural gas quantity expected to enter Bulgarian territory is 54,6 mcm/d with minimum pressure of 4,5 MРa. The maximum natural gas quantity, expected to reach Bulgarian-Serbian border is 34,4 mcm/d with maximum pressure of 6,5 MРa. The expected new infrastructure has a diameter Dn 1200, and study provides as well for two new compressor stations. The initial year of transmission in line with non-binding nominations is gas year 2019/2020, and expected commercial commissioning of incremental capacity is 1 October 2019. The expected amount of investment is up to BGN 2.8 billion, VAT excluded. The expected operational costs are BGN 131.428 mln/year.

V. Indicative steps to conducting Open Season s Phase 3 In line with good EU s practices Open Season procedure goes through two main stages. During first stage an assessment of market needs is carried out (Phase 1 (completed) and Phase 2). During second stage (Phase 3) a binding capacity request shall be submitted by participants of procedure and in case of a successful procedure, participants sign binding agreements (Transport Contracts). Based on analysis of need of incremental capacity following Phase 2 and if re will be need, a second furr fine-tuned option of a preliminary investment plan for new projects will be developed, including investments in pipeline network, compressor stations, gas metering stations, etc. Phase 3 Capacity allocation and Binding Agreements (planned for period 17 October 2018 31 December 2018) Launch of incremental capacity allocation procedure, including applicable tariff, longterm capacity allocation mechanisms, etc.; Submission by users of binding offers for long-term incremental transmission capacity; Economic test and analysis of economic viability of projects; Signing of binding Transport Contracts. In parallel a process of preparation of Cooperation Agreements/Memorandums of Understanding/Interconnection Agreements, or any or binding or non-binding agreements with neighboring TSOs/project companies will be in place in order to coordinate implementation time schedule of interconnected projects for a new/expansion of existing infrastructure and implementation of Transport Contracts.
