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: Qmax = 1.940.000 cm/day (≈ 80k cm/h)
• pressure: pmin = 30 b, pmax = 45 b (g), (Δp ≈ 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): Qy ≈ 880 m cm/year (Δp ≈ 18b/136 km)

Q2: Is Current pipeline Capacity sufficient for B&H ?

• Yes, for reasonable demand, (in 2017: ƞTR = 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): (ƞBK = 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) (Δp ≈ 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 (?)

Q4: Are You planning new pipeline construction ?

• Pipeline Shepak-Bijeljina (L = 25 km) is under construction
• Under consideration: Batajnica-Bijeljina pipeline, 20’‘ 102km
• 3 pipelines would eventually create (Δ) ring structure with:
• existing pipeline Batajnica-Zvornik,
• Shepak-Bijeljina pipeline (under construction) and
• Batajnica-Bijeljina pipeline (under consideration).
• Ring structure (Batajnica-Bijeljina-Shepak) would relax

transportation strain on existing pipeline Batajnica-Zvornik

• This might be the way to avoid CS construction and provide

second entry point (near Bijeljina) for B&H/RS, as well.

• This entry point is for “RS horizontal connection” (slide 10)

Pipeline CAPEX and OPEX as function of Capacity

• Small Diameter pipeline (DN400) with relatively low CAPEX
• Capacity increase requires higher OPEX (Compressor St.)
• More maintenance (ageing pipeline , 39 years), with ƞTR ≈ 1/3
• Fixed costs regardless on ƞTR , impacting transportation tariffs

Existing Pipeline Technical issues - Reminder

• Pipeline is Underused, but overbooked (ƞ ≈ 34%)
• Older Pipeline (39 y), needs more maintenance
• No UGS in B&H, line pack is limited (L, D, p)
• Huge seasonal variations (1:10 ≥ 1:15)
• Pressure drop is result of hydraulics (L,D,Q,OP)
• A FEW Compressor Stations are missing (min. 1)
• OP limit with no serious impact so far (pmax=45 b)
• No reverse flows, no gas rings inside B&H
• No additional Entry Points (for (n-1), SOS)

NG ON B&H ENERGY MARKET

• (90+) % Fossil Fuels based B&H Energy Sector

(66% Coal, 25% Oil, 3% Natural Gas) (slide 5)

(13% Coal, 43% Oil, 24% Natural Gas, 14% NE, 6% R) (EU 2003)

• Unfavorable price relation (electricity vs NG):

(it should be ≈ 3:1 per kWh, ƞTE ≈ 1/3)

• Limited growth potential of NG Market

(no real development without TEP & Industry) (source: Rambǿl, NERA, WB, EBRD Studies)

• Uncertainty on gas Supply Routs for EU&SEE
• Geopolitics, Economy, EU Gas Market (Reg1%)

TSO GAS PROMET – FUTURE ACCTIVITES

• Improving mettering system (state entry point Zvornik), USM
• Introducing quality metering (state entry point Zvornik), PGC
• Balansing, allocation and line pack issues w/upstream TSO
• Gasification of Bijeljina (pipeline DN 400 under construction)
• CNG & LNG as way to increase gasification and consumption
• Coordinating TSOs system (with regional grid) development
• Building new infrastructure w/new entry points

(next 10 y)

• Improving technical SOS , (n-1), (2nd entry point, BN),
• Implementation of new Republic of Srpska Gas Law
• Implementation of EU/EZ 3rd Energy Package
