The European Union Agency for the Cooperation of Energy Regulators (ACER) on April 14, 2026, published a proposal calling for enhanced coordination among EU member states and grid operators to accelerate investments in electricity distribution networks. The document, issued by ACER's Electricity Department, recommends that national regulatory authorities and distribution system operators (DSOs) align planning frameworks and share best practices to meet the growing demand from electrification and renewable energy integration.
The proposal, titled 'Enhanced Coordination for Electricity Distribution Investment Ramp-Up,' is a non-binding recommendation that sets out concrete steps for improving investment efficiency. It suggests that DSOs adopt common methodologies for cost-benefit analysis and grid planning, and that national regulators establish harmonised incentive schemes to encourage timely investments. The document also calls for increased transparency in grid data to facilitate cross-border coordination.
Policy orientations and trade-offs ACER's proposal aims to address the investment gap in distribution grids, which are critical for integrating distributed renewable generation and electric vehicle charging. The agency estimates that EU distribution grid investments need to increase by 50% by 2030 to meet climate targets. However, the recommended coordination could lead to higher upfront costs for DSOs and national regulators, who may need to upgrade IT systems and align regulatory frameworks. The trade-off involves balancing the benefits of harmonised planning—such as reduced duplication and faster deployment—against the administrative burden and potential loss of local flexibility.
Impact on stakeholders - Distribution system operators (DSOs): Will face new reporting obligations and may need to adjust investment plans to align with common methodologies. This could increase short-term costs but improve long-term planning certainty. - National regulatory authorities: Must develop harmonised incentive schemes, requiring legislative or regulatory changes in some member states. This may strain resources but could lead to more efficient grid investments. - Consumers: Could benefit from lower electricity costs in the long run due to more efficient grid investments, but may face higher tariffs in the short term to cover increased investment costs. - Renewable energy developers: Will gain from faster grid connections and reduced curtailment, as coordinated planning should improve grid capacity for variable renewable sources.
Expected institutional follow-up ACER's proposal will be discussed at the next meeting of the European Electricity Regulatory Forum (Florence Forum) in June 2026. The European Commission is expected to issue a communication on grid investment later this year, potentially incorporating ACER's recommendations into legislative proposals. National regulators are encouraged to submit feedback by September 2026.
