4.3.2 PIPELINE DEVELOPMENT PROJECTS
Currently, there are two major gas transmission development projects underway in
Estonia – Balticconnector pipeline and Enhancement of Estonia-Latvia interconnec-
tion project (PCI 8.1.1 and 8.2.2, respectively). The projects will connect the Baltic
and Finnish gas networks and help to diversify sources and routes, and will enable
competition on the regional gas market.
The Balticconnector project consists of a subsea bidirectional pipeline between
Inkoo, Finland and Paldiski, Estonia along with grid enhancements in both countries.
The transit capacity of the offshore pipeline will be 81.2GWh/d and the compressor
stations in Finland and Estonia enable transit flows between the two countries.
The Enhancement of Estonia-Latvia interconnection project consists of making the
Karksi GMS bi-directional (currently gas can only flow into Estonia from Karksi
GMS), increasing the capacity of GMS and building of compressor station in Puiatu.
The compressor station in Puiatu is necessary for enabling transit flows between
Finland and Baltic countries.
4.3.3 LNG TERMINAL PROJECTS
Currently there are two LNG terminal development projects in Estonia with a region-
al scope. The LNG terminals would serve the regional gas market of Finland and
Baltic countries and increase the security of supply of the region. Paldiski LNG
terminal’s planned capacity is 180,000–320,000m³ of LNG and Tallinn LNG termi-
nal’s planned capacity is 320,000m³ of LNG.
