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).

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.

How does wind energy affect electricity prices in Denmark?

The abundance of wind energy has helped to keep electricity prices low in Denmark, as wind energy is a low-cost source of electricity compared to many other forms of energy. However, the variability of wind speeds can also lead to significant fluctuations in electricity prices.
