EU adopts regulation to gradually phase out Russian gas imports

The Council of the European Union has adopted a regulation phasing out Russian imports of pipeline gas and liquefied natural gas (LNG) into the EU, marking a step forward in delivering the REPowerEU objective of ending the EU’s reliance on Russian energy, responding to ongoing risks stemming from Russia’s war of aggression against Ukraine and its use of energy as a political weapon. The regulation introduces a stepwise ban on Russian gas imports, alongside measures on monitoring and diversification of energy supply.

ACER publishes guidance on cybersecurity performance monitoring for EU electricity networks

The Agency for the Cooperation of Energy Regulators (ACER) has published guidance on the voluntary submission of information to support the monitoring of cybersecurity-related operational reliability performance indicators in the electricity sector under the Network Code for Cybersecurity (NCCS). The guidance establishes three performance indicators applicable to high-impact and critical-impact entities under the NCCS, which cover: (1) the annual number of reportable cyber-attacks assessed as having high or critical gravity; (2) the annual number of reportable cyber threats; and (3) the annual number of exploited unpatched (zero-day) vulnerabilities. According to ACER, the indicators are intended to support consistent and comparable monitoring of cybersecurity risks with potential operational consequences for cross-border electricity flows, while minimising data sensitivity.

DESNZ publishes RO scheme indexation consultation outcome confirming CPI transition

The Department for Energy Security and Net Zero (DESNZ), the Scottish Government, and the Northern Ireland Executive have published their joint response to the Renewables Obligation (RO) scheme indexation consultation and confirmed the decision to change the inflation indexation from the Retail Price Index (RPI) to the Consumer Price Index (CPI). This change will take effect for the 2026–27 compliance year, beginning in April 2026 and the RO buy-out price will be adjusted annually in line with CPI.

Commission launches call for evidence on removing barriers to power purchase agreements

The European Commission has launched a call for evidence on removing barriers to power purchase agreements (PPAs), as part of preparations for a Commission recommendation planned for Q2 2026. The initiative aims to help dismantle regulatory and non-regulatory barriers that continue to limit the signature and use of PPAs in some Member States, despite their role in funding new clean energy infrastructure and providing long-term price stability for electricity producers and buyers. The Commission’s assessment will focus on identifying remaining and additional barriers under current EU legislation, including those affecting the development of renewable energy installations, such as permitting requirements, and those impeding the efficient functioning of electricity markets. The consultation closes on 20 February 2026.
