Will state aid be available for large-scale electricity storage systems?

In autumn 2024 two draft regulations were published regarding state aid for large-scale electricity storage systems (BESS), one from the Modernisation Fund (“MF ”) 1 - and the second under the National Recovery and Resilience Plan (“RRP ”) 2.

What is g11.3 energy storage systems?

The “G1.1.3 Energy Storage Systems” programme is being developed to support lithium-ion technology for energy storage and power off-take facilities connected to the national grid. According to the Draft RRP Regulation:

Do energy storage systems need a safety assessment?

Safety Assessment: As more energy storage systems have become operational, new safety features have been mandated through various codes and standards, professional organizations, and learned best practices. The design and commissioning teams need to stay current so that required safety assessments can be performed during commissioning.

Do energy storage subsystems have to pass a factory witness test?

Each subsystem must pass a factory witness test (FWT) before shipping. (Note: The system owner reserves the right to be present for the factory witness test.) This is the first real step of the commissioning process—which occurs even before the energy storage subsystems (e.g., power conditioning equipment and battery) are delivered to the site.

Which components of a battery energy storage system should be factory tested?

Ideally, the power electronic equipment, i.e., inverter, battery management system (BMS), site management system (SMS) and energy storage component (e.g., battery) will be factory tested together by the vendors. Figure 2. Elements of a battery energy storage system
