As fossil fuel generation is progressively replaced with intermittent and less predictable renewable energy generation to decarbonize the power system, Electrical energy storage (EES) technologies are increasingly required to address the supply-demand balance challenge over a wide range of timescales.
The major result is that the perspectives of electricity storage systems from an economic viewpoint are highly dependent on the storage's operation time, the nature of the overall system, availability of other flexibility options, and sector coupling.
As the amount of electricity generated by variable renewable energy technologies (VARET), mainly wind and photovoltaics (PV) increases, electricity storage technologies and their relevance for the wholesale electricity markets becomes more vital.
The major result is that the economics of electricity storage are highly dependent on storage operation time, availability of other flexibility options and sector coupling options. In the last few decades, electricity markets virtually worldwide were subject to significant alterations.
As carbon neutrality and cleaner energy transitions advance globally, more of the future's electricity will come from renewable energy sources. The higher the proportion of renewable energy sources, the more prominent the role of energy storage. A 100% PV power supply system is analysed as an example.
Since the early beginnings of the electricity system, storage has been of high relevance for balancing supply and demand. Through expanded electricity production by variable renewable technologies such as wind and photovoltaics, the discussion about new options for storage technologies is emerging.
