The economic effect of energy storage construction has received increasing attention in recent years, as the use of renewable energy sources has grown, and the need for reliable and flexible power systems has become more pressing.
Overall, the available literature suggests that energy storage construction can have significant economic benefits, including reduced costs of power generation, improved reliability of the power grid, and reduced carbon emissions. However, the existing research has mainly focused on the energy sector in a national or global region.
With energy storage, there are energy losses due to the round-trip efficiency which contributes to the loss of revenue [ 31, 77 ]. The LCOE for GIES is higher than non-GIES. This is due to a lower efficiency (i.e. energy output) for thermal energy storage, although the capital cost is lower.
Energy storage technologies (ESTs) aim to address the volatility and uncertainty of renewable sources and thus solve the difficulties with grid connection and improve the match between electricity supply and demand by the increasing proportion of renewables in the electricity mix.
The Department of Energy Global Energy Storage Database provides the construction time for energy storage projects [ 60 ]. The average construction time for grid-scale energy storage with a wind power generator is four years. For inputs with the known upper and lower bounds, the average is determined from the two values.
Energy storage is costly and, with these market conditions, generation alone without energy storage is the most profitable. With energy storage, there are energy losses due to the round-trip efficiency which contributes to the loss of revenue [ 31, 77 ]. The LCOE for GIES is higher than non-GIES.
