The TSO annual statement is an important document for the development of the Latvian electricity system, since it puts forward and addresses several possible generation scenarios, analyzes consumption and peak load, evaluates the electricity balance for a ten year period, and informs about available capacities to cover the daily load in the near future.
Based on this report as well as ten year development plan of transmission system of Latvia developed by AS "Augstsprieguma tīkls", ten year network development plan of the European Network of Transmission System Operators for Electricity (ENTSO-E), which in turn is one of the founding documents on the basis of which the Member States, the European Union is able to co-finance the development projects of electricity system and market integration.
Reports
The report analyses the ability of Latvia’s electricity system to maintain the balance between electricity generation and consumption across seasonal, daily and hourly timeframes. It also assesses the potential of energy storage, demand response, aggregation and interconnections, possible market barriers, as well as the impact of electricity network digitalisation. The report concludes that, under the analysed development scenarios for 2030 and 2035, no issues have been identified in Latvia’s electricity transmission and distribution systems that would compromise the reliable operation of the power system.
The first report was prepared in 2026 by Latvia’s electricity transmission system operator AS “Augstsprieguma tīkls” (AST), in cooperation with the distribution system operator AS “Sadales tīkls”, and was approved by the Public Utilities Commission (PUC) on 6 August 2026.
The report has been prepared in accordance with Regulation (EU) 2024/1747 of the European Parliament and of the Council of 13 June 2024, adopted by the European Parliament, amending Regulations (EU) 2019/942 and (EU) 2019/943 as regards improving the Union’s electricity market design (hereinafter referred to as the “Regulation”). Article 19e of the Regulation requires each Member State to carry out a Flexibility Needs Assessment (FNA).
Pursuant to Article 19e(1) of the Regulation, no later than one year after the Agency for the Cooperation of Energy Regulators (ACER) has approved the methodology in accordance with paragraph 6, and every two years thereafter, the regulatory authority or another authority or entity designated by the Member State shall adopt a report on the estimated flexibility needs at national level for a period of at least the next five to ten years. The report shall take into account the need to cost-effectively achieve security and reliability of supply and decarbonise the electricity system, while considering the integration of variable renewable energy sources and different sectors, as well as the interconnected nature of the electricity market, including interconnection targets and the potential availability of cross-border flexibility.
