Lithuania Solar Cybersecurity Compliance and Enforcement

Under Construction

Lithuania has implemented stringent cybersecurity rules allowing grid operators to disconnect solar plants over 100 kW that fail to comply. The regulations address risks related to supply-chain concentration, operational remote access, and retrofitting security measures onto existing infrastructure. New renewable installations above 100 kW have had to meet these requirements since May 1, 2025, and existing plants since June 1, 2026. Grid operators now have the authority to disconnect non-compliant solar assets, with some flexibility for plants in implementation. Compliance costs for new plants are relatively low, but retrofitting older systems is costly and faces implementation backlogs. The focus is on inverters as critical control points, with concerns over vendor remote access, especially from Chinese manufacturers. This move highlights the operational risks of a vast network of remotely accessible assets and raises questions about control and security integration in Europe's renewable energy transition.
