SCADA Services

We provide engineering and design services for a wide array of Supervisory Control and Data Acquisition (SCADA) systems ranging from large substation and control center systems to small remote systems. We can help justify, recommend, and provide design, engineering, and plans and specifications for complete data acquisition and control systems; replacement, upgrade, or expansion of existing systems; and operator interface equipment including ergonomic features. Our services include:

  • Energy management
  • Switchgear control
  • Data acquisition and alarm
  • Test data analysis
  • Position indication for circuit breakers and disconnect switches
  • Transformer tap changers
  • Electrical analog values including amps, volts, watts, VARs, and power factor
  • Sequence of events and trending

Studies & Relay Setting Services

We design protection systems that provide service continuity, safety, and maintenance protection to T&D assets. Power system load growth requires periodic evaluation of the utility transmission system to verify its continued capability to reliably maintain service continuity during peak loading conditions. Our services include:

  • EHV and HV relay system design
  • Transmission planning studies
  • Fault current and load flow studies
  • Protective system selection and design
  • Protective system coordination (e.g., relay selection recommendation and settings)
  • Protective equipment specification (e.g., breaker, recloser, fuse, and other device selections)
  • System transient analysis
  • System component protection
  • Distributed generation system analysis
  • DC system design
  • Substation grounding analysis and design
  • Arc flash studies
  • Motor starting studies
  • Harmonic analysis studies

Construction Support

  • Cost estimates
  • Field review and coordination
  • Material resolution
  • As-built records

Additional Integrated Distribution Services

Our full suite of distribution services means we provide fully integrated project services, all in-house. Our services include:

  • Survey & Geomatics
  • Environmental Assessments Permitting & Compliance
  • Geotechnical
  • Transportation Infrastructure
  • Telecom
  • Physical Security
  • Civil Engineering
  • A/C Mitigation Design
