The EU's energy regulatory apparatus is moving decisively on grid infrastructure, with ACER and DG ENER simultaneously advancing transparency tools, cost-sharing reform, and AI-driven grid management—signaling that grid modernization, not just generation buildout, is becoming the binding constraint for the energy transition. Meanwhile, China's 2% Q1 emissions rise despite record renewables deployment underscores that without adequate grid infrastructure and flexibility mechanisms to integrate clean energy, even massive capacity additions fail to displace fossil fuels at the pace required.

ACER launches electricity network tariff transparency repository
ACER has launched the first edition of its electricity network tariff repository, a new tool designed to improve transparency of European electricity network tariffs across member states. The tool enables systematic comparison of grid access charges, a critical variable for industrial location decisions and cross-border competition.

ACER policy paper proposes reform of cross-border infrastructure cost and benefit sharing
ACER published a policy paper exploring how Europe could reform the sharing of costs and benefits of cross-border electricity infrastructure projects. The paper aims to unlock grid investments needed for a more integrated European electricity market, addressing a long-standing bottleneck where projects with pan-European benefits stall due to asymmetric national cost allocation.

Carbon Brief analysis: China's CO2 emissions rose 2% in Q1 2026 despite massive renewables buildout
Carbon Brief analysis shows China's CO2 emissions grew 2% in the first quarter of 2026, driven partly by curtailment of wind and solar generation ('wasted' renewables). Despite record renewable capacity additions, grid integration failures meant fossil fuel consumption continued to rise.

ACER releases adequacy assessment for Ireland and Northern Ireland highlighting interconnection needs
ACER released its Opinion on the All-Island Resource Adequacy Assessments for Ireland, Northern Ireland and the Single Electricity Market (SEM), concluding that interconnection is central to security of electricity supply. The assessment underscores growing adequacy risks in island systems heavily reliant on variable renewables.

Agora Energiewende publishes analysis on reforming PPAs for flexible coal power
Agora Energiewende published on 2 June 2026 an analysis on reforming power purchase agreements for flexible coal power, examining how PPA structures can be redesigned to facilitate coal phase-out while maintaining system flexibility. The publication addresses the tension between accelerated coal exit timelines and grid reliability requirements.

ACER issues opinions on gas network code derogations at third-country interconnection points
ACER published opinions on requests from seven national regulatory authorities seeking derogations from applying EU gas network codes and guidelines at interconnection points with third countries. The decisions affect how gas (and potentially future hydrogen) flows are regulated at the EU's external borders.
