Gas storage: major investments in improving ‘Inčukalns’ already in place

The Latvian operator of the natural gas transmission and storage system, Conexus Baltic Grid (Conexus) has announced that within the framework of the European investment project of common interest, 36.3 million euros have been invested thus far in improving the operation of the Inčukalns Underground Gas Storage (UGS). This includes 9.7 million euros in the first nine months of this year, both in well rehabilitation works and in the purchase and installation of various equipment. 

This year, workovers have been completed on 8 wells, bringing the total number of completed workovers to 29 out of 36 wells.

As part of the work to upgrade the gas collection point, the construction project for the rehabilitation of gas collection point 3 has been approved – all the necessary pipes and fittings have now been delivered, as well as some of the basic process equipment. In parallel, the second phase of the procurement of the works is underway, with technical and financial bids to be submitted by the tenderers. 

Upgrading work has also been completed on three of the five existing gas pumping units in Compressor station number 2, whilst three of the five fuel and pulse gas preparation units have been installed. The installation of the remaining two fuel and impulse gas preparation units is in progress, as well as the supply of equipment for the upgrading of the last two gas pumping units.

In early October, a contract was signed with Solar Turbines, an internationally renowned company, for the supply of a new gas injection unit package with a contract value of 21.65 million euros. Work is currently underway on the technical solutions for the new gas pumping unit to enable the company to start production in the near future. Work is also ongoing on the design work provided by the Slovak company GasOil Technology a.s.

“The Inčukalns Underground Gas Storage is the largest project to date since the opening of the natural gas market and I am pleased with its systematic and coordinated implementation,” said Rinalds Dimiņš, Conexus Inčukalns Underground Gas Storage Facility Manager. “In cooperation with our colleagues and partners, we have already been able to carry out substantial and technically complex work, thus improving the technical infrastructure and operational reliability of the storage facility.”

The project runs until the end of 2025 with has a total investment of 88 million euros, half of which is covered by funding from the Connecting Europe Facility (CEF). The project will rehabilitate the above-ground infrastructure and wells, upgrade the existing five gas pumping units and install a new additional gas pumping unit. As a result, improving the security of the natural gas supply, increasing the operational capacity of the storage facility and facilitating integration into the international energy market.
