What are PCs and energy related costs?

PCS costs of the EES system are typically explained per unit of power capacity (€/kW). Energy related costs include all the costs undertaken to build energy storage banks or reservoirs, expressed per unit of stored or delivered energy (€/kWh).

How much does PCs cost?

In addition to the specific features of the site, the cost of storage depends on the plant size, 69 $/kWh (52 €/kWh) for a 14.4 GWh plant while 103 $/kWh (77 €/kWh) for 11.7 GWh storage capacity . The results of this study show the cost of PCS of 513 €/kW and storage cost of 68 €/kWh, on average.

How are energy storage systems priced?

They are priced according to five different power ratings to provide a relevant system comparison and a more precise estimate. The power rating of an energy storage system impacts system pricing, where larger systems are typically lower in cost (on a $/kWh basis) than smaller ones due to volume purchasing, etc.

Which energy storage technologies are included in the 2020 cost and performance assessment?

The 2020 Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air energy storage, and hydrogen energy storage.

Are mechanical energy storage systems cost-efficient?

The results indicated that mechanical energy storage systems, namely PHS and CAES, are still the most cost-efficient options for bulk energy storage. PHS and CAES approximately add 54 and 71 €/MWh respectively, to the cost of charging power. The project׳s environmental permitting costs and contingency may increase the costs, however.

Do EES systems have a significant uncertainty in PCs and O&M costs?

The review of the cost data of EES systems reveals that the uncertainty in PCS costs, O&M costs, and replacement costs are also considerable for some EES technologies (see Section 4.1).
