The key point is that installing 300 kW of storage allows the utility to avoid a one time charge of $135,000. From the perspective of utility ratepayers, that is a one-time, single-year benefit of $135,000 for a storage plant with a power rating of 300 kW. The storage is worth $135,000/300 kW = $450/kW of storage.
