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.
