Maturity assessment process for BESS projects reaches distribution grids
With Netze BW, for the first time a major distribution system operator is introducing a points-based allocation procedure for grid connections of 950 kW and above. For project developers, this means that land, permits, and technical planning must be reliably in place in good time – the first application window opens as early as November 2026.
EEG 2027 & Grid Package: Cabinet Decision on the Refinancing Contribution (CfD) at a Glance
As of August 12, 2026 | This article is based on the cabinet decision on the Renewable Energy Sources Act (EEG 2027) and the grid package dated July 29, 2026. The legislative process has not yet been completed; details are subject to change in the further course of the procedure.
AgNes Draft Determination 2026: The Network Fee Reform from 2029 at a Glance
Things are getting serious for battery storage systems: The draft AgNes regulation provides for new capacity fees – while at the same time the clock is ticking for the 20-year exemption. Anyone planning a new storage system will likely have to make the final investment decision before January 1, 2027.
Water scarcity in Europe: Why this causes problems for energy supply
Low river levels in Europe are forcing several nuclear power plants to shut down for the first time and are also putting coal, gas, and hydroelectric power plants under pressure. Our overview shows why the climate crisis is increasingly becoming a challenge for energy supply and what role battery storage systems will play in the future.
MiSpeL 2026: Regulation enters into force on October 1st and what does that mean for BESS projects?
MiSpeL is considered one of the most important regulatory advances for storage in Germany. In practice, it is now crucial when the new rules will come into effect and be usable.
Solar power saved EU gas imports worth €20 billion & could cut demand by a quarter by 2030
Since the escalation of the Iran conflict alone, solar power has notionally saved the EU 20 billion euros in gas imports. Further expansion could reduce the EU's gas demand by another 25 percent by 2030.
Energy Sharing in Germany: Status of Implementation under Section 42c EnWG (2026)
Grid operators are supposed to enable it starting in June 2026 – yet the major breakthrough is still a long time coming. Our overview shows what hurdles exist, why full grid fees hamper profitability, and for whom the model can still be worthwhile.
EU Commission presents ETS reform: More free certificates, slower falling cap
The European Commission wants to noticeably weaken emissions trading from 2031: more free allowances, a relaxed market stability reserve, and new ETS sectors could have a lasting impact on the CO₂ market.
Grid Package 2026: Final draft passes Federal Cabinet
3 % becomes 5, and 10 years becomes 6: The BMWE has slightly relaxed the requirements for capacity-constrained grid areas. However, this does nothing to change the fundamental shift in risk at the expense of plant operators—and the criticism under European law also remains.
EMD Directive: Status of German implementation after the deadline expiration
The Electricity Market Design Directive (EU) 2024/1711 had to be transposed into German law by July 17, 2026. With the amendment to the Energy Industry Act (EnWG) of November 2025, Germany has already implemented central parts, but is still considered delinquent by the EU Commission: An infringement procedure (INFR 2025/0127) is underway because the complete transposition was not notified on time.
