What does the European Commission say about energy storage?

The Commission adopted in March 2023 a list of recommendations to ensure greater deployment of energy storage, accompanied by a staff working document, providing an outlook of the EU’s current regulatory, market, and financing framework for storage and identifies barriers, opportunities and best practices for its development and deployment.

What are energy storage options?

Energy storage options provide applications and services that match technologies to needs. Already, several reports indicate the technical and economic benefits that storage has over conventional technologies, particularly in ancillary service markets , .

Should energy storage be utilised in the design and operation of networks?

The Commission also encourages further exploiting the potential of energy storage in the design and operation of the networks. Some recommendations also address challenges related to a need for long-term visibility and predictability of revenues to facilitate access to finance (for example monetising services provided).

What are the different types of energy storage?

Note that other categorizations of energy storage types have also been used such as electrical energy storage vs thermal energy storage, and chemical vs mechanical energy storage types, including pumped hydro, flywheel and compressed air energy storage.

Should energy storage be included in network charges and tariff schemes?

In concrete terms, the Commission is recommending EU countries to consider the specific characteristics of energy storage when designing network charges and tariff schemes and to facilitate permit granting. The Commission also encourages further exploiting the potential of energy storage in the design and operation of the networks.

How important is sizing and placement of energy storage systems?

The sizing and placement of energy storage systems (ESS) are critical factors in improving grid stability and power system performance. Numerous scholarly articles highlight the importance of the ideal ESS placement and sizing for various power grid applications, such as microgrids, distribution networks, generating, and transmission [167, 168].
