study for a projected 2.0 MW photovoltaic (PV) solar panel system that BWP is installing on top
of the Regional Intermodal Transportation Center (RITC) parking structure at the Bob Hope
Airport located on Hollywood Way and Empire Avenue. The solar power will be interconnected
to the 12 kV Golden State-11 (GS11) radial distribution feeder, and brought directly back into
BWP’s system.

interconnection to the BWP system, including any impact to the Golden State 11 feeder. The
study also includes the impact of a sudden loss or increase of PV output on the voltage profile
and any other related impact on the customers served from the GS11 12 kV distribution feeder,
the Golden State substation and the Burbank transmission system.
BWP requested that POWER perform a protection audit of the GS11 feeder, which led to
recommendations for SCADA and special protection schemes to protect the distributed
generation and the BWP feeder, since the feeder would no longer be considered radial with the
new generation.
