The proposed Project, which is a part of the LA100 Initiative, would construct a 30-megavolt ampere (MVA) distributing station (DS-104) that would step down voltages from LADWP’s existing higher-voltage sub-transmission system for distribution of energy to customers within the community through the lower-voltage distribution system.
DS-104 would consist of a control room, restroom, transformers, circuit breakers, switchgear, interconnection apparatus, and other associated equipment all enclosed within the distributing station structure. The distributing station, including vehicle access and parking, would occupy approximately one acre within LADWP’s existing two-acre property. DS-104 would be operated remotely and would not require daily on-site staff. The design of DS-104 would include features to ensure compatibility with existing conditions in the community, including noise and aesthetics. Design options under consideration include the use of wall-enclosures, locating equipment indoors, and undergrounding circuits serving customers.
Customers would be served by six new underground lower-voltage distribution feeders exiting DS-104 to connect with the existing distribution network of the area. Connecting DS-104 to the existing 34.5-kilovolt (kV) sub-transmission system would require modifying the existing sub-transmission circuits to loop into and out of the new DS-104 site. New segments of sub-transmission circuits would also be needed elsewhere in the City of Los Angeles to supply the new DS-104 with energy and to create system redundancy with other existing stations on the LADWP network, including the existing DS-29. System redundancy would improve the reliability of electric service to customers in the area and prevent blackouts.
Because adding DS-104 to the system would alleviate electrical loads on existing facilities, the installation of DS-104 would also facilitate the removal of certain PTDS equipment in the area which have been installed over the last several years because of the above stated measures to make up for limits of DS-29.
Construction of DS-104 is expected to commence in the Fall of 2024 and would continue for approximately 42 months.
