Abstract :
This paper determines how the value of customer-sited PV can be increased with battery storage by enhancing the load management
and outage protection attributes of PV. Case studies in San Jose, CA and Long Island, NY for residential and commercial PV applications
are used for a quantitative illustration of storage value enhancement. Results indicate that: (1) a small amount of storage for local
load control and a larger amount of storage for emergency load protection significantly increases the value of distributed PV to the customer;
(2) the value of PV combined with emergency storage exceeds the sum of the value of these options implemented separately; and
(3) there is a potential opportunity to use dispersed PV + storage to enhance grid security (capturing this value, however, will require
regulatory and policy changes).
