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).

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

IEEE. Zeh, A., Muller, M., Naumann, M., & Hesse, H. (2016). Fundamentals of using battery energy storage systems to provide primary control reserves in Germany. Batteries. Table 9 carries the requirements and the remuneration for units participating in the Danish ancillary services markets.

Are there opportunities for value-stacking in Danish electricity markets?

After going over the main features of the Danish electricity markets – with a focus on the provision of ancillary services – opportunities for value-stacking (utilizing opportunities across markets) are identified and examined for the year 2025 at the transmission grid level.

What are the costs derived from the Danish technology catalogue?

Cost figures are derived from the Danish technology cata-logue (DEA and Energinet, 2019); operation and maintenance costs are ne-glected as their effect is limited. The figures do not include costs and revenues from arbitrage activities (i.e. from the charging pattern in the proposed strat-egy).

Do batteries need to be charged for energy deficit?

Depending on the market area, a battery needs to be charged for the energy deficit created in the market as a minimum. The energy deficit includes round-trip losses and all the energy not exchanged in the market but that contrib-utes to the overall system balance18.

Is electric storage a good investment?

Electric storage has experienced a growing interest in the last years due to a general cost drop, its manifold potential applications in the energy sector and a wide array of technological options.
