Bsu energy storage

Should battery energy storage units (BSUs) be regulated in Ireland?

Considering the policy perspective at the European level, and a comprehensive assessment of the regulatory and electricity market instructions at the national level in Ireland, we recommend policies for enabling the full potential of battery energy storage units (BSUs).

Can a BSU be aggregated?

If a BSU is registered as a generation unit, under the definition of aggregated generating units that currently exist in the SEM glossary , it could be aggregated provided to have <10 MW capacity. The same is true for the DSUs since if a DSU has >10 MW demand reduction capacity, it should be registered as an individual DSU.

Do battery energy storage units need different voltage levels?

Numerous papers in the literature state that the integration of renewables necessitates the deployment of battery energy storage units (BSUs) at different voltage levels .

Are battery energy storage capacity auctions a good idea?

The result of capacity auction shows that the not only the existing battery energy storage do not participate in the capacity auctions, the capacity market is not attractive for the new BSUs in comparison to the other technologies.

Should a battery energy storage compete with a conventional generation unit?

Based on current market instructions in Ireland, a battery energy storage should not only compete with conventional generations units, but also interconnectors are functioning as serious rivals, especially in the capacity market.

Can PSHS be used as long-duration energy storage units?

PSHs as long-duration energy storage units will significantly contribute to the future storage mix in other jurisdictions while this is not possible for Ireland due to the geographical limitations. Fig. 7. Comparison of Ireland's planned storage mix and the battery storage leading countries.
