Rewire. #271 — Monday, 28 Sep 2026

Rewire. — Morning Briefing
Monday   28 Sep 2026 · Nº 271
Signal
The Commission is wielding infringement proceedings on two fronts simultaneously—18 member states over RED III/IV energy-sharing rules and all but one over the low-carbon hydrogen directive—signaling that transposition delays have exhausted Brussels' patience across the clean energy framework. This enforcement push contrasts with member-state-level acceleration on the ground, from Italy's tenfold-scale MACSE premium cap of €27,000/MWh/year to Germany's €200m e-fuels grants, exposing a widening gap between EU legal mandates and national implementation speed.
AI-generated illustration: transposition as a carbon-copy set: the original sheet is written full, the flimsy copies beneath it came out blank, because the carbon that was supposed to do the reproducing was never put in.

Commission opens infringement cases against 18 member states over energy-sharing rules
The European Commission has begun infringement proceedings against two-thirds of EU member states for failing to implement the right for consumers to share renewable electricity across the grid, a requirement under the revised Electricity Market Directive, according to PV Magazine. The affected states have not enacted the necessary national provisions within the transposition deadline.

Commission opens proceedings against all but one member state over low-carbon hydrogen directive
The European Commission has launched infringement proceedings against every member state except one for failing to transpose the directive setting rules for low-carbon hydrogen, according to Hydrogen Insight. Separate Italian reporting names Italy as the only country to have transposed the green-gases directive.

Italy lifts MACSE storage auction premium cap to €27,000/MWh/year
Italy's energy regulator Arera has set the premium cap for the MACSE storage capacity auction at €27,000/MWh per year, up from the €22,000/MWh proposed in July, citing higher benchmark investment costs, according to PV Magazine. The premium is fixed for 15 years, and developers must weigh it against merchant revenue potential.

EU may shift solar inverter restrictions from countries to individual high-risk suppliers
Proposed amendments to the EU's Cybersecurity Act would move the assessment of 'high-risk' suppliers away from a country-based approach toward evaluations of individual companies, PV Magazine reports. The change could reshape how restrictions on solar inverter vendors are applied, though specific suppliers and measures have not been finalised.

Mercedes-Benz to trial ProLogium 'Gen4' lithium-ceramic cells
Mercedes-Benz and ProLogium have signed an agreement giving the carmaker preferential access to test ProLogium's next-generation 'Gen4' cells, which the supplier describes as a lithium-ceramic battery combining properties of solid-state technology, according to batterynews.de. The claims originate from the supplier and no independently verified performance data — energy density, C-rate, cycle life or cost — is provided in the report.
