Short Term Battery Storage Could Eliminate Need Fossil-Based Backup Capacity

Battersea power station in London

Earlier we reported about considerable progress being made in bringing down the price of storage of electrical energy. This could greatly reduce the need for maintaining fossil fuel based backup capacity. In the modern grid there is always spare capacity standing by, that can be switched on quickly to meet varying demand patterns. If indeed the cost of storage could be brought down to ca. 100-200$/kwh, than the need for the spare capacity mentioned above could be considerable reduced and backup power stations can be closed.

And it is not just batteries that will replace the need for backup generation capacity, there is also the option of pumped hydro storage, that could cover both short and medium term storage capacity.
