RO-HU-AT - a pilot project for incremental capacity GRI SEE 13 December 2016, Bucharest RO-HU-AT - a pilot project for incremental capacity How to develop functioning markets? Infrastructure needs and initiatives for Europe RO-HU-AT - a key project for Central and South-East Europe

Starting Point 2014 Network users indicated non-binding demand for long term transportation services potential natural gas supplies originating from an upstream project initiative in the Black Sea from Romania (RO) via/to Hungary (HU) and further on to Austria (AT)

Physical gas flows in the region

PCI 6.24 - ROHUAT Expansion and refurbishment of the existing gas transportation systems

New gas route - ROHUAT

Incremental capacity process To coordinate the process and to find suitable solutions in the framework of the incremental capacity Regulatory Authorities To express the need for new infrastructure To support the initiative to give valuable inputs Network users TSOs To prepare the open season/ incremental process To plan the necessary construction works

The following 3 allocation methods have been consulted Market survey A market survey on different capacity allocation methods was conducted by the TSOs in February 2016 The following 3 allocation methods have been consulted 13 responses form market participants

Method 1 Market integration Ascending clock auction algorithm according to Art. 17 of the CAM NC Bundled capacity offered as single years in the auctions

Allocation rule core logic: Market integration Method 2 3 allocation rounds foreseen Allocation rule core logic: Round 1: 15 year commitment for both IPs Round 2: 1 year commitments for both IPs Round 3: 1 year commitments for single IPs (same as Mechanism 1) Round 1 Round 2

preferred option according to outcome of market survey Market integration Method 3 Bundled capacity offered as single years in the auctions (same as Mechanism 1) If demand > offer, capacities shall be allocated on the basis of the highest individual bidder commitment in all auctions conducted throughout the period of 15 years at IP Csanádpalota and IP Mosonmagyaróvár Allocation rule core logic: NU contribution = price IP1 * demanded capacity IP1 * number of years + price IP2 * demanded capacity IP2 * number of years Method 3 preferred option according to outcome of market survey

Examples Austrian side Economic test

Austrian coordinated network development plan 2017-2026

Determination of the economic viability (Austrian side) The economic tests (Economic Test I and Economic Test II) for incremental capacity at the entry point Mosonmagyaróvár are based on the following parameters: PVAR = 156.325.000 EUR f = 0.75 PVUC ≥ 117.243.750 EUR The economic test will be positive if the value of binding commitments of network users is equal to or higher than 117.243.750 EUR. As the allocation of all incremental capacity at the reference price (i.e. 0.77 €/kWh/h/y) would not generate sufficient revenues for a positive economic test outcome, a mandatory minimum premium (i.e. 3.31 €/kWh/h/y) (supplement) is applied for the allocation of the incremental capacity. The mandatory minimum supplement has been calculated based on the assumption of 1.913.490 kWh/h/y minimum booked incremental capacity for 15 years in a row.

Determination of the economical viability Conditions for the calculation of the mandatory minimum premium: 30% of the technical capacity flat booked for 15 years 25% of the total costs socialized on existing IPs

Determination of the economical viability base case: generated revenues

Determination of the economical viability base case: generated revenues

Determination of the economical viability Tariff composition for the base case

Negative economic test

Negative economic test to be reallocated to top of the initial mandatory premium

Negative economic test Increasing of the minimum mandatory premium part of the tariff ∆ +1,64

Positive economic test

Positive economic test to be subtracted from the initial mandatory premium

Positive economic test decreasing of the minimum mandatory premium part of the tariff ∆−𝟎,𝟖𝟗𝟐

Overall economic tests The project will be realized if all the 4 economic tests in direction RO -> VTP AT will be positive the 2 economic tests at the IP Csanadpalota will be positive
