5.09.2024. Study: Innovative grid technologies can improve renewable energy integration in the Latvian grid by up to 40% a

The study, ordered by Latvian transmission system operator JSC "Augstsprieguma tīkls" and carried out by French consultancy Artelys, shows that innovative grid measures can help increase the hosting capacity of the grid by up to 40% in the best case. The increase of electricity demand in Latvia, especially hydrogen technologies, can allow to connect additional amounts of RES to the transmission network, which was also evaluated in the study.

2.04.2024. Study: a faster electricity consumption increase is expected in Latvia

The green transformation of the European Union is moving society towards a modern and competitive economy, to achieve the climate neutrality goals in 2050. With the significant increase of the amount of renewable energy sources and the simultaneous development of electrification, a faster electricity consumption increase is expected in Latvia after 2030. In the period from 2030 to 2035, the increase of consumption can reach up to 100%, according to the results of the study on consumption development trends in the Baltic and Nordic countries, prepared by the KPMG consultant and exercised by AS "Augstsprieguma tīkls" (AST).

13.07.2017 Integration of the Baltic States into the EU electricity system: A technical and economic analysis

In the spring of 2017 European Join research center has finalised the study “Integration of the Baltic States into the EU electricity system: A technical and economic analysis”. Upon investigating possible technical and economic scenarios on de-synchronizing the networks of Baltic countries from power systems of Russia and Belarus and synchronizing with networks of Europe, has been concluded that from the technical and economic point of view it would be more favorable for Baltic countries to become synchronized with continental Europe, as it has been stated in the study prepared by the European Join Research Centre and published by European Commission.
