Our associated company SiG Coop, a Navarra-based consultancy specialised in demonstrating compliance with grid codes in energy projects, has carried out the first ‘Black Start’ study in Spain applied to battery energy storage systems. This technical procedure makes it possible to verify a facility’s ability to contribute to restoring electricity supply after a total or partial blackout.
The analysis, developed in accordance with the new requirements established by IDAE and the system operator Red Eléctrica, has evaluated several storage systems from a power company. The results confirm that these infrastructures have the necessary capabilities to actively participate in grid restoration in blackout scenarios, as well as to strengthen system stability.
According to SiG Coop, as reported to Navarra Capital, these types of solutions represent a significant shift in the role of renewable energy within the power system. Thanks to technological development and the support of storage, these sources can take on more active functions, contributing not only to energy generation but also to grid formation (‘grid forming’) and improved resilience.
Storage as a key driver in the evolution of the energy system
The study is part of the ongoing evolution of the energy sector, where storage is becoming increasingly strategic. The growing penetration of renewable energy sources, characterised by their variability, together with an increasingly distributed and complex grid, is driving the need for solutions that enable generation management and ensure system stability.
In this context, SiG Coop has expanded its activity into the field of energy storage and demand, incorporating services to verify grid code compliance for battery systems and large energy consumers. These types of studies may be required by both manufacturers and developers of energy infrastructure.
Navarra on the energy storage map
Navarra reflects this trend with significant growth in battery storage. Currently, there are 2,680 MW planned across 111 battery installations in the region, positioning it as a relevant player in the development of these technologies.
This context creates new opportunities for the local business ecosystem, particularly in engineering, consultancy and technical services related to the integration of these solutions into the power grid.
International projection and new markets
SiG Coop operates in a strongly international environment, with a presence in markets such as Portugal, Italy, Greece, the United Kingdom, the United States, Brazil, Australia and South Africa. In recent months, the company has expanded into countries such as Finland and Denmark, known for their highly demanding grid requirements.
Looking ahead, the company also plans to strengthen its presence in emerging markets where there is still significant renewable generation capacity to be integrated, such as Georgia, Poland and Romania.
