The Lithuanian power transmission system operator Litgrid is continuing its cooperation with the Japanese energy company TEPCO Power Grid and is starting to prepare a study to evaluate technical and economic alternatives for offshore wind integration.
The study is carried out taking into account the objectives of the National Energy Independence Strategy, which states that by 2050 80% of Lithuania’s energy needs must be met by energy from environmentally friendly resources and 100% of all electricity consumption in the country will be met by locally generated electricity. The expansion of renewable energy sources with a strong focus on the expansion of offshore wind energy is envisaged as one of the most important measures to achieve these goals.
In 2023, Lithuania plans to announce the auction to integrate the first 700 MW offshore wind energy into the Lithuanian electricity system. The total offshore wind potential in the territorial waters of Lithuania can be up to 3.5 GW.
In order for the offshore wind integration to be technically advanced and cost-effective, it is necessary to consider the possible different configurations of the network, their technical parameters, the reliability of the system, the newly emerging market opportunities, and the socio-economic advantages of such projects. This is exactly what Litgrid will focus on together with TEPCO in the preparation of the study.
The main conclusions of the study are to be published in spring 2022. Liutauras Varanavičius, head of the strategy department at Litgrid, notes that conducting such a study is important not only for the efficient implementation of national energy targets, but also for the realistic development of the offshore power transmission network in the region.
‘The study evaluates alternatives to the construction of a hybrid offshore power transmission network with neighboring countries, the potential of using the existing and newly constructed connection lines. Litgrid is actively involved in the initiatives to expand the offshore power transmission network in the Baltic Sea region. Thus, the results of the study will provide more arguments for regional discussions’, – says L. Varanavičius.
This is the second study that Litgrid is collaborating with TEPCO on. This spring, TEPCO, together with the Baltic operators, evaluated the recommendations and described the minimum requirements for electricity generation from renewable sources.
The Japanese transmission system operator TEPCO Power Grid has extensive experience in the management and development of the power grid, including grid operation under extreme conditions. The company is also responsible for reliably powering small, remote islands and contributing to the development of energy from renewable sources.
