Figure 4.6: Gas transmission network of Estonia

4.3.1 GAS TRANSMISSION NETWORK

Currently the gas transmission network is connected to Russian (at Värska GMS and Narva interconnection point) and to Latvian (at Karksi GMS) gas networks. Majority of the pipeline was built 30–60 years ago. A newer branch pipeline to Pärnu was built ten years ago. Also two parallel pipelines are crossing Estonia in the southeast area. The parallel pipelines are used for gas transportation between Russia and Latvia. Majority of the pipeline is designed to operate at 50 bar (Maximum operating pressure). Currently only the northern pipeline (connecting Tallinn and Narva inter- connection point) is limited to 30bar. During the summer season gas is typically supplied through Värska GMS and Narva interconnection point. During the winter season gas is typically supplied from Inčukalns UGS through Karksi GMS and Värska GMS.
