Inverter, Storage and EMS Forum (ISEF)

The “Inverter, Storage and EMS Forum facilitated by ESMC” (ISEF) strengthens Europe’s energy security and strategic autonomy by promoting a resilient, competitive, and cyber-secure ecosystem of Western inverter, storage, and EMS manufacturers. As critical digital components of the energy system, these technologies must be trustworthy, transparent, and shielded from both technical and non-technical risks that are linked to software and firmware updates, remote-access capabilities, and supply-chain dependencies. In particular, the Forum emphasises that non-technical risk factors – such as governance structures, ownership, external influence, and the overall trustworthiness of entities – are as decisive for security as technical safeguards.

The Forum discusses and prepares industry positions, replies request of the EU and national authorities, and contributes to ongoing EU initiatives – including the NZIA, Cyber Resilience Act, Cyber Security Act, NIS2, and all relevant energy security measures – to ensure strong and future-proof regulatory frameworks. It is committed to high cybersecurity standards, secure-by-design technology, and diversified Western supply chains that reduce dependence on a dominant source of supply. The Forum promotes reliability, accountability, and long-term trustworthiness of entities interacting with Europe’s critical energy infrastructure.

Open to ESMC members and eligible Western non-members, the Forum collaborates widely with grid operators, energy-security agencies, standardisation bodies, and other stakeholders, and actively participates in EU fora to advance Europe’s digital and energy resilience.
