Kewo Engineering Corporation designs and reviews the electrical and civil systems behind substations, transmission, protection, battery storage and EV charging for Southern California's utilities, ports, transit agencies and cities. We are a certified small business in Diamond Bar, California.
Brian Kewo founded the firm in 2014 after working in substation design at the Los Angeles Department of Water and Power, where he managed and engineered projects from $20,000 to $79 million. We work directly for public agencies and as a subconsultant to the large engineering firms that lead their programs.
Founder and President. M.S. Electrical Engineering (Electric Power) and M.S. Financial Engineering, University of Southern California; B.S. Electrical Engineering, Cal Poly Pomona. Senior Member, IEEE Power and Energy Society.

From first study through commissioning, as prime or subconsultant.
Electrical and civil design from concept through issued-for-construction drawings and specifications.
Substations and switchyards, transmission and distribution lines, duct banks, protection and control, grounding, lighting and foundations, delivered at 30, 60, 90 and 100 percent. Supporting studies include grounding, photometrics, AC/DC load, short circuit, arc flash and protection coordination.
Example Receiving Station X, 230/34.5 kV, 320 MVA, for LAWA and LADWP
Owner's engineering, submittal review, construction monitoring and commissioning support.
We act as the agency's technical representative on design-build and EPC contracts: reviewing contractor submittals, tracking schedule and cost, monitoring construction, and closing out with commissioning and as-built drawings. Led by a PMP and Certified Construction Manager.
Example Glenarm BESS, Owner's engineer, 25 MW / 100 MWh, for Pasadena Water and Power
Technical specifications, bid documents and bid evaluation for major electrical equipment.
Mobile substations, battery storage, EV chargers, breakers and switchgear. We write the technical requirements, answer bidder questions, evaluate proposals, and check Buy America (BABA) compliance on federally funded work.
Example Mobile substation, Technical specification for Pasadena Water and Power
Training for utility staff on new systems, equipment and standards.
Classroom and field training on substation automation, protection systems and newly installed equipment, plus the manuals and standards that keep the knowledge in-house after the project ends.
Example Substation automation, Project controls and training support for LADWP
Independent review of design packages before they reach construction.
Third-party QA/QC of protection and control designs, drawings, cable schedules, material lists and calculations, checked against utility standards and the governing codes.
Example Center Substation, QA of 66 kV protection and control design for SCE
Recent work for utilities, transit agencies, ports and cities.
Storage and solar
Pasadena Water and Power, 2025–2026
Review of EPC contractor submittals and support through construction, commissioning and as-builts, covering equipment, CAISO metering, civil and structural work, arc flash and protection coordination.

Interconnection study for the Glenarm battery energy storage project.
New 320 MVA, 230/34.5 kV receiving station serving LAX, the first LADWP receiving station built in over three decades. Electrical design at 30, 60, 90 and 100 percent, four 230 kV underground duct banks, and construction support, with grounding, photometric and AC/DC load studies.
Replacement of series capacitors and associated equipment at the McCullough and Victorville switching stations. Electrical design of conduits, grounding, bus work, breakers, switches, CVTs, line traps and SCADA/HMI support, plus submittal review and construction monitoring.
Engineering support for replacement of the ground return system at Sylmar.
Technical specification for a utility mobile substation.
Quality assurance review of the protection and control design for replacement 66 kV breakers and disconnects and new line PTs: design drawings, cable schedules and material lists.
Protection and RTU upgrades across three substations. At Park, 11 relay racks removed and 17 installed; at Anaheim, 7 racks converted to SEL RTAC and Axion. Site visits, system design and drawings to city standards.
Engineering, project controls and training support for LADWP's substation automation program.
Battery storage and solar PV at the district's bus barn, an EPRI-supported project.
Single-line diagram for a 5 MW solar PV plant's utility interconnection application.
Utility coordination with LADWP on lines, poles and temporary pole relocation, and electrical documentation for the affected buildings submitted to LADBS.
Moving overhead power and communication lines underground with a new pad-mounted transformer: site assessment, underground distribution design, SCE coordination and permitting.
Electrical design services for overhead distribution upgrades.
Lighting design for the South Oxnard Library and South Oxnard Center.
Update of Metro's zero emission bus master plan: lifecycle program cost framework, ZEB operations strategies, regional charging needs, and transition planning for contracted service divisions.
Method of service study with Southern California Edison for LA Metro.
Construction management for electric bus chargers at two bus yards.
Program management for the city's EV charging, energy storage and solar infrastructure.
EV charger expansion at the utility's maintenance yards.
Foundations design at Control Point Dayton.
