Over half of all storage capacity in the queues is proposed in hybrid configurations with generation (358 GW). Interest in hybrid projects is especially strong in CAISO and the non-ISO West, where 97% and 81% of all proposed solar is in a hybrid configuration, respectively.
At present, energy storage can be broadly classified into two categories: power-type energy storage and energy-type energy storage [21]. The former has a high power density but usually a small capacity, which is suitable for suppressing high-frequency and short-term fluctuations in power system [22].
