Unbundling ongoing – to be finished by 1 Jan 2020

Ukrainian government approved on 18 Sep 2019 the Resolution determining the final model of unbundling and the procedures to be finished by EOY. Action plan with clear steps and deadlines for all participants of UA natural gas market was approved. Most importantly for implementation of the EU business rules – the company responsible for submission of certification request and the party of interconnection agreements is determined – TSO LLC

Interconnection Agreements prepared – to be signed

Amendment for Interconnection Agreement between Ukrainian and Romanian TSOs prepared but not yet signed. The first draft of Interconnection Agreement between Ukrainian and Moldavian TSOs for IP Oleksiivka is prepared and is currently discussed by the TSOs.

Reconstructions on UA and MD facilities

Ukrainian TSO will finalize the reconstructions to enable reverse flow metering on GMS Grebenyky by end of October 2019. Moldavian TSO is also expected to finalize the reconstruction of GMS Kaushany by EOY.

Capacity allocation

In accordance with Ukrainian Network code, quarterly and monthly capacities of interconnection points, in particular new interconnection import point from Romania, are allocated in December 2019 – 30 calendar days before the beginning of the period for which capacity is allocated. Pending issues and problems to be urgently solved

Reconstruction of GMS Isaccea-1

Amendment to Interconnection Agreement between Ukrainian and Romanian TSOs are not yet signed. Moreover, there is no update from Romanian side about the ongoing process and no information about commissioning date of new ultrasonic GMS Isaccea-1, which hinders the initiative as such. To our best knowledge, Romanian TSO started reconstruction of existing GMS, but we are not officially informed thereon.

Determination of the commercial metering station for IPs Orlovka-Isaccea 2-3 and IP Tekovo

For continued transportation of natural gas between Ukraine and Romania for all interconnection points it is necessary to sign Interconnection Agreements between Ukrainian and Romanian TSOs. The main remaining unsolved issue is determination of commercial gas metering stations to be used from 1 January 2020. This also threatens the reverse flows on IPs Orlovka-Isaccea 2-3.

Capacity auctions from RO side for reverse flows

Romanian TSO did not auction annual capacity of IP Isaccea-1 in July 2019. On 4 November 2019 quarterly capacities shall be allocated. Moreover, the Romanian TSO informed that there will be no firm capacities in direction to Ukraine due to their obligation to provide firm capacities to , which hinders the reverse flow possibility

Synchronization of quality parameters of natural gas

In case of transportation of natural gas from Romania to Ukraine there is a need to align quality parameters, prescribed by legislation of Romania and Ukraine. The issue is not yet solved and hinders physical transportation of gas from Romania to Ukraine

Transportation of natural gas via

There are existing risks of continued transportation of natural gas between Ukraine and Moldova, as well as transportation of gas through due to uncertain legal status of Tiraspoltransgas and unbundling of TSOs in Moldova. Thank you for your attention!
