Project purpose and objectives

The Balticconnector pipeline project will play a major role in the energy strategies of both Finland and the EU. The project will

  • Improve regional security of supply by diversifying gas sources
  • Create a framework for market opening and growth and enable the use of alternative sources, such as liquid natural gas (LNG) and biogas
  • Enables the interconnection of the Finnish and Baltic gas markets and their integration with the EU’s common energy market

The total cost of the project is EUR 250 million. The project would not be viable without considerable support from the EU. In 2016, the European Commission (CEF) granted funding of EUR 187.5 million to the project.

Improvements in the gas transmission systems between Estonia and Latvia, and between Poland and Lithuania, will coincide with the Balticconnector project. Together these projects will enable the integration of the Finnish and Baltic systems with the EU’s common gas market.

Project scope

The project will comprise the construction of pipeline systems, stations and facilities to connect the existing gas networks in Finland and Estonia. The transmission capacity of the pipeline will be 7.2 million cubic metre (72 GWh) per day. Gas can be transported bi-directionally between Finland and Estonia according to market demand.

The project has been divided into the following subproject:

  • Onshore pipeline Siuntio-Inkoo (Finland) with a pipe diameter of 500 mm and length of 22 km
  • Compression and metering station, Inkoo (Finland)
  • Offshore pipeline Inkoo (Finland) - Paldiski (Estonia) with a pipe diameter of 500 mm and length of 77 km
  • Compression and metering station, Kersalu (Estonia)
  • Onshore pipeline Paldiski-Kiili (Estonia) with a pipe diameter of 700 mm and length of 47 km

aikataulu-en

Siuntio-Inkoo Onshore Pipeline

In Finland, the pipeline will join the current transmission system at the Pölans valve station in Siuntio and enter the Baltic Sea at the Fjusö landfall site in Inkoo. The pipeline route will mainly run through the municipality of Inkoo and, for a short distance in the northern part of the route, the municipalities of Lohja and Siuntio.

The pipeline route takes account of the area’s current and future land use, planning and environmental considerations. It is based on minimising the impact of construction and any adverse effects on people, organisms and the environment during the operation of the pipeline. The Environmental Impact Assessment of the pipeline was completed in December 2015.

Applications for the pipeline’s construction permits will be submitted during the planning stage. These include the construction permit, underwater construction permit, building/activity permits and crossing permits.

Land will, if necessary, be purchased through the expropriation procedure. The expropriation permit will be granted by the Government. The land for the pipeline will be expropriated using a permanent access right. Consultation meetings will be held with the interested parties before the expropriation application is submitted.

Gas compression and metering station, Inkoo

The facility comprises a gas compression and fiscal metering station. The station is bi-directional, i.e. it can deliver gas both ways between Finland and Estonia. At the metering station, the volume of gas is measured and its quality analysed. The compression station increases the gas pressure, when necessary, to enable the transmission of the required volume of gas. The station will be located in the area of Svartbäck in Inkoo.

The general location of the station was influenced by the conditions associated with the operation of a gas system. Factors affecting the more specific location included land use, planning, and environmental considerations. An Environmental Impact Assessment of the station was completed in December 2015.

Applications for the station’s construction permits will be submitted during the planning stage. These include among other things construction and building permits.

Compression and metering station technical specification

  • The station’s metering capacity is 300,000 m³n/h
  • The station is monitored remotely and controlled from the system’s central control station
  • The station is an independent facility that will not require external auxiliary energy sources
  • Gas transport flow in both directions FIN-EST and EST-FIN
  • One compression unit with an input power of 6-10 MW, located in a separate compression facility
  • Gas filtering and analysis equipment
  • Gas fiscal metering equipment and automation system
  • Separate local control station with space for electric and automation systems
  • Onshore and offshore pipeline pig receivers and launchers

Milestones

  • Basic planning 2017
  • Procurement of main equipment 2017
  • Detailed planning 2017 - 2018
  • Award of main contracts 2017 - 2018
  • Construction and installation works 2018-2019
  • Commissioning 2019

Inkoo-Paldiski Offshore Pipeline

The offshore pipeline will join the Siuntio-Inkoo onshore pipeline at the landfall site located approximately 1 km from the Inkoo compression and metering station in the area of Fjusö. The pipeline will run along the seabed and will largely be covered by rock. The rock cover will protect the pipeline from hazards such as ship anchors and erosion. The pipeline landfall site will be located approximately 50 km east of Tallinn, near the town of Paldiski.

The route’s planning takes account of the seabed’s formation and conditions, crossing structures and shipping lanes. An Environmental Impact Assessment has been conducted of the offshore pipeline. The EIA report was completed in 2015 in Finland and in 2016 in Estonia. A comprehensive risk assessment has also been carried out.

Applications for the pipeline’s construction permits will be submitted during the planning stage. These include the project permit, water permit, construction permit and building/activity permits. The pipeline will be laid in the territorial waters and exclusive economic zones of Finland and Estonia.
