Backup Power

Generators & Transfer Switches

Standby generation and the transfer equipment that decides whether the facility rides through an outage.

Standby power is two systems that have to agree with each other: a generator that starts and a transfer scheme that hands it the load cleanly. Access specifies both together, in diesel and natural gas, from light commercial sets up to paralleled plant.

What we supply

  • Diesel standby generators
  • Natural gas and bi-fuel generators
  • Automatic transfer switches
  • Static and static bus transfer switches
  • Paralleling switchgear
  • Load bank testing and commissioning

Who we represent for generators & transfer switches

The outcome

Specified correctly, supported for its lifecycle.

A standby system that has been load bank tested and maintained is the difference between backup power on the drawing and backup power at 3 a.m. We commission what we install and keep it on a service program, so the first real transfer is not also the first test.

How we support it

Power Systems

Resilient power from the service entrance to the load — sized, conditioned, and backed up so critical loads remain protected through power disturbances and outages.

  • Generators & automatic transfer switches (ATS)
  • UPS systems & power conditioning
  • PDUs, modular busway & distribution
  • Surge protection & DC power plants

Monitoring

Continuous eyes on every critical system — connected assets, real-time telemetry and alarms that reach a human with somewhere to go.

  • Connected assets across mixed manufacturers
  • Real-time telemetry and condition data
  • Alarm management, escalation and notification
  • Analytics, trending and lifecycle intelligence
