Can energy storage units be installed in the Danish power system?

Elsystemansvar A/S (subsidiary of Energinet) has asked Ea Energy Analyses to analyse the benefits and main drivers for the installation of storage units in the Danish power system. This will supplement the technology aspects in the recent Technology Catalogue on Energy Storage (DEA and Energinet, 2019).

Which storage demonstration projects have been carried out in Denmark?

As reported in Table 1, two significant storage demonstration projects were carried out in Denmark in the past years. The batteries installed in Nordhavn (Copenhagen) were tested mainly for the provision of primary regulation (TSO service) and peak shaving (DSO service).

How are energy services delivered in Denmark?

Some of the services are delivered through energy markets in Denmark (they are referenced in each of the subsections); certain are remu-nerated in other countries, e.g. in the US, or are not linked to any compensa-tion at all.

Why do we need a high-voltage substation?

In the coming years, several high-voltage substations on the ‘high-ways’ of the Danish electricity grid are needed to secure that renewable electricity can be connected to the grid and transported around the country.

Is a storage facility a challenge in Denmark?

In Denmark, a storage facility can by definition (Energinet, 2019): The participation of storage assets in different markets may be a challenge. These challenges might be just as much a consequence of regulatory design as technical limitations.

Do battery energy storage systems provide primary control reserves in Germany?
