Technical FAQs 4

Are battery energy storage systems a key part of the Nordic energy transition?

Battery energy storage systems (BESS) continue to play a vital role in the Nordic energy transition. Based on Marsh's experience in advising BESS owners in the Nordics, cold climate challenges, ensuring safety, and optimizing spacing are key topics that are discussed for BESS development in the region.

What is a battery energy storage system (BESS)?

The project in Hasle is the largest battery energy storage system (BESS) in the country, EWII said, and will provide flexibility services to transmission system operator (TSO) Energinet as it decarbonises the grid. It is comprised of 116 battery units.

How will Bess impact the Nordics?

BESS will have a large impact on energy systems in the Nordics, helping the move toward carbon neutrality. However, ignoring the specific needs for BESS installations in the region could slow down progress. For more information on how these risks may affect your business, contact your Marsh advisers.

Why is the Nordic electricity system considered a good choice?

The Nordic electricity system is considered because it is a well-interconnected market and can thus serve as an example in the energy market design for the other European countries . Moreover, its energy mix is dominated by renewables, thus giving it a hint of the desired future European power system , , , .
