Enerleg Newsletter – June 2026

From the new environmental criminal code to ETS benchmarks, from the REMIT node on wholesale prices to the deadlines of ETS2 and storage: the June issue gathers the measures that, in the coming weeks, will change the way those working in energy, environment, and industry operate.

There is a thread that connects this month's updates: the gap between the norm and practice is narrowing, and with it grows the responsibility of those who must apply these norms every day. This is clearly seen in the reform of environmental criminal protection, effective from June 2, 2026, which takes sustainability out of the ESG perimeter and into corporate criminal law: new crimes, the notion of "illegality" that cracks the authorization shield, and 231 Models to be revised without delay.

But the picture is broader. In Brussels, the Commission is redesigning the EU ETS benchmarks for 2026-2030 and preparing the allocation of free allowances; in Italy, the ARERA investigation on capacity withholding reopens the debate, worth five billion euros, between bidding strategies and REMIT obligations; ETS2 enters the operational phase, with the opening of accounts in the Union Registry and a window closing on September 15, 2026; Terna schedules the MACSE auction for new storage with delivery in 2029. Different deadlines, one message: reliable data, clear roles, and aligned documents are needed before a deadline becomes an urgency.

In this issue

• Environmental criminal protection – Legislative Decree 81/2026 redesigns crimes, aggravating factors, and entity responsibilities: what concretely changes for companies and 231 Models.
• EU ETS1 – new 2026-2030 benchmarks, 75% free allowances, and coverage of indirect emissions to boost industrial electrification.
• REMIT and capacity withholding – ARERA's investigation on the Day-Ahead Market and the open issue with the Capacity Market.
• ETS2 – opening of deposit accounts in the Union Registry: the window for already authorized Regulated Entities runs from June 1 to September 15, 2026.
• Storage – Terna's MACSE auction for new storage capacity with delivery in 2029: timing and participation methods.

As always, our goal is to read the norm alongside practice and translate it into sustainable choices on technical, legal, and economic levels.
