Brussels, Belgium — (METERING.COM) — June 6, 2013 – Battery energy storage technologies will play a vital role in the development of a decarbonized power system in Europe, according to a new paper from the Association of European Automotive and Industrial Battery Manufacturers (EUROBAT).
According to the paper, Battery energy storage for smart grid applications, decentralized battery energy storage provides a mobile and scalable solution to answer specific local problems raised by renewables integration at the distribution level of the grid. Services for grid operators include peak shaving in the low voltage grid, load leveling in the LV grid, frequency regulation, and voltage control.
Battery energy storage also has a high potential to create interest and momentum at the customer level for end-users. Benefits include time-shift for self-consumption, time-shift for feed-in, smoothing of renewables feed-in, and uninterruptible power supply (UPS).
The paper notes that batteries of all technologies – lead, lithium, nickel and sodium – are already available on the market to address the storage needs of TSOs, DSOs and customers at each level of the electricity grid. While continued R&D is needed to further reduce prices and improve performance, their market introduction and further development should be given immediate support by policy makers and standardization bodies.
Additionally, to facilitate the short term market introduction of battery energy storage, especially at distribution and customer levels, it is recommended that decentralized energy storage must be seen as an integral part of the development of Europe’s future smart grid. A market framework for energy storage should be developed at an EU level, and member states should evaluate the specific potential for deployment of energy storage technologies at all levels of their electricity system. The further development of battery energy storage should also be prioritized in all EU-level R&D initiatives, at both cell and system levels.
A second paper reviews battery energy storage for rural electrification systems, stating that batteries are an essential component of all stand-alone off-grid and hybrid mini-grid systems, being used to provide renewable energy storage and increased efficiency.
Used correctly in off-grid and mini-grid systems, battery energy storage can improve the reliability of power supply from renewable and conventional sources, increase overall system efficiency, and provide economic savings across the system life cycle. To take advantage of these benefits, system operators must ensure that their battery sizing is fitted with the system’s technical, environmental and situational requirements.
