HYDRAULIC CALCULATION OF EXPANDING GAS FLOW ( for TSO GPP TRANSPORTATION SYSTEM ) Structure: single pipeline, no rings, no UGS, 1 KS, one direction of flow Total Length = 176 km * (136 + 20 + 40) Diameter = 16“ (DN 400) DP = 50 bar OP = 45 bar (max. at KS Batajnica, Belgrade) No of CS = 1 Batajnica KS, Belgrade, Serbia (at beginning of transportation route) Max flow = 100% load = 77.500 m3/h (at MS Zvornik) Delivery pressure = 30 bar (min, at MS Zvornik, i.e. at 136 km from KS) Z factor according to AGA NX-19 (corrected) λ factor (hydraulic friction) calculation based on Re Number Simulated as expanding flow of compressible fluid Simulated for set of 8 input pressures, with 100%,75%,66% and 33% load Results: diagrams of p, v, Z and ρ

Q1: Current vs. designed pipeline capacity • NG Entry point for B&H: PPS ZV (Zvornik, Karakaj) Guaranteed delivery parameters at PPS ZV: - flow: Q max = 1.940.000 cm/day ( ≈ 80k cm/h) - pressure: p min = 30 b , p max = 45 b (g), ( Δ p ≈ 13b/136 km) • Transportation capacity: Q ≈ 710 m cm/year (ƞ ≈ 0.34) • Year of last pigging: 2011. • 241 mcm in 2017: (RS: 68.7 FBiH: 172, SRB: 0.4) • at (2.4 mcm/d, 50b): Q y ≈ 880 m cm/year ( Δ p ≈ 18b/136 km) NG Pressure at B&H entry point PPS Zvornik, Januar 2017, (bar, g) 50 40 30 20 10 0 1 182 363 544 725 906 1087 1268 1449 1630 1811 1992 2173 2354 2535 2716 2897 3078 3259 3440 3621 3802 3983 4164 4345 4526 4707 4888 5069 5250 5431 5612 5793 5974 6155 6336 6517 6698 6879 7060 7241 7422 7603 7784 7965 8146 8327 8508 8689 Series1 Series2

Q2: Is Current pipeline Capacity sufficient for B&H ? • Yes, for reasonable demand , (in 2017: ƞ TR = 242/710 ≈ 0.34 ), but • It barely covers winter daily maximum: ( Jan 2017 : 1.87 mcm/day) • Daily average consumption (2017): 241/365 = .66 mcm/day • Daily capacity booking (2018): (ƞ BK = 0.927) 1.8 of 1.94 mcm/day • Capacity booking (2018): 5/6 FBiH, 1/6 RS (is this unfair?) • Age of pipeline 39, (1979) (2/3 of average expected lifetime) Technical measures to mitigate this (booking) situation: - shaving winter consumption peaks (using auxiliary fuel) - pipeline weak point reconstruction (up to DP = 50 b) - construction of Compressor station(s) ( Δ p ≈ 1/3 at CMP Zvornik) - construction of UGS in B&H (if feasible/needed) - creating “gas rings” for better network use (whenever feasible) - building new natural gas infrastructure. (next 10-15 years)

Q3: Are the pipeline reconstruction & repair necessary ? • Regular maintenance is conducted, pigging is due . • Depending on future solutions, (previous slide): - intelligent pigging (pipeline inspection) should be done - based on results, remaining lifetime to be estimated - additional reconstruction and repair works might be needed - Feasibility Study should be done, including each proposal : - building new Compressor station(s) - construction of UGS in B&H (Tuzla salt mine) - creating “gas rings” structure where possible - building new infrastructure. • Could this (Feasibility Study) be focal point of this USAID EIA Project in Natural Gas Sector (?)
