Critical Power Services
Your partner for mission-critical power
From hyperscale data centers to hospital standby plants and continuous-duty co-generation - SDP Power keeps Southern California's most critical loads online. Every program is engineered to your redundancy, compliance and uptime requirements.
Mission-Critical
Data Center & Mission-Critical Power
Engineered support for facilities where downtime is not an option - colocation, hyperscale, edge, healthcare and financial operators.
Data Center Generator Programs
Concurrent-maintainable service plans aligned with Uptime Institute Tier requirements, including N+1/2N redundancy validation.
Commissioning & Consulting
Factory and site acceptance testing, integrated systems testing (IST), pull-the-plug exercises and owner's-rep consulting to validate every layer of redundancy before go-live and guide design decisions on new builds and expansions.
Capacity & Reliability Studies
Modeling and field measurement of generator, UPS and switchgear capacity to support new tenant fit-outs, power densification and AI/HPC load growth.
24/7 Emergency Response
Dispatched field technicians with stocked service trucks for after-hours failures, PSPS events and storm response.
Prime & Continuous Power
Prime Power & Co-Generation
Around-the-clock power for sites operating off-grid or running base load - built and maintained for thousands of run hours per year.
Prime Power SystemsLearn more →
Service and maintenance of diesel and natural gas prime-power generators sized for continuous operation at variable load.
Co-Generation (CHP)Learn more →
Combined heat and power systems - engine, heat-recovery and controls service to maximize fuel efficiency and uptime.
Plant Assessments
Reliability assessments and gap analyses for prime power and CHP plants - identifying single points of failure, end-of-life equipment and opportunities to improve heat rate, availability and run-hours between overhauls.
Performance Optimization
Heat-rate analysis, tuning and trending to keep prime-power assets at peak efficiency.
Standby & Emergency
Standby Emergency Power
Preventive maintenance and rapid repair for the standby systems protecting hospitals, public safety, telecom and commercial real estate.
Preventive Maintenance ContractsLearn more →
Customized PM programs built around manufacturer service intervals, NFPA 110 requirements and your facility's runtime profile. Includes scheduled inspections, oil and coolant sampling with trend analysis, fuel polishing and tank cleaning, battery load testing and replacement, cooling system service, exercise runs under load, and detailed digital service reports for every visit.
Repairs & Maintenance
One-time repairs, equipment upgrades and annual maintenance for standby generator systems - covering diagnostics and troubleshooting, component replacements (injectors, turbos, alternators, batteries, controllers), control and ATS upgrades, and scheduled annual service to keep your standby plant inspection-ready and reliable when you need it.
Automatic Transfer SwitchesLearn more →
Full new ATS installations, plus service, repair and upgrades for existing gear from ASCO, Russelectric, Cummins, Kohler, GE/Zenith and others. We handle bypass-isolation switches, time-delay and exerciser programming, contact and coil replacement, and full functional testing with the generator under load.
Load Bank Testing
Resistive and reactive load bank testing to ANSI/NETA and NFPA 110 standards - proving full-rated kW performance under controlled load, exercising wet-stacked engines and validating cooling, exhaust and fuel systems before they're needed in an emergency.
NFPA 110 Compliance
Level 1 / Level 2 EPSS testing, documentation and reporting for AHJ and insurance audits - including monthly exercise records, annual full-load testing and 4-hour endurance runs.
Controls & Compliance
Switchgear, Controls & Emissions
The systems that orchestrate, protect and certify your power plant - from paralleling switchgear to CARB / SCAQMD compliance.
SwitchgearLearn more →
Service, troubleshooting, retrofits and full upgrades for medium-voltage and low-voltage paralleling switchgear from Russelectric, ASCO, Cummins PowerCommand, Woodward, Caterpillar EMCP, ComAp and others. Capabilities include synchronizer and load-share calibration, dead-bus and live-bus paralleling, utility import/export tuning, breaker maintenance, and HMI / SCADA upgrades to extend the life of legacy lineups.
Engine Controls & PLCsLearn more →
Diagnostics, repair and tuning of engine governors (Woodward, Heinzmann, Barber-Colman), generator controllers (DSE, ComAp, EMCP, PowerCommand) and plant PLC/SCADA systems (Allen-Bradley, Siemens, Modicon). We rebuild aging panels, migrate obsolete logic to modern controllers, integrate BMS/EPMS protocols (Modbus, BACnet, SNMP), and commission new control narratives with full functional testing.
Emissions Controls & Equipment UpgradesLearn more →
Service, repair and full equipment upgrades for SCR, DPF and oxidation catalyst systems - including catalyst replacement, urea/DEF system rebuilds, dosing and injector upgrades, NOx sensor replacement and aftertreatment retrofits to bring older units up to current Tier 4 / BACT performance.
Protective RelaysLearn more →
Testing, calibration, programming and coordination studies for SEL, GE Multilin, Beckwith, Basler and SEL-700 series protective relays. Services include acceptance and maintenance testing per NETA/IEEE standards, settings development, arc-flash and selective coordination studies, and full documentation for AHJ submittals.
