Bringing Control to Standby Generator Use
A review of emergency generator deployment helped a regional utilities organisation reduce avoidable standby provision, improve response planning, and align equipment use with real operational risk.
The Lay of the Land
The Challenge
The organisation used standby generators to support essential operations during planned and unplanned outages.
Over time, equipment had been deployed out of caution rather than clear operational need. Some generators were positioned on sites where the risk profile had changed, others were retained after the original purpose had passed, and several were being used as an informal safety measure rather than as part of a structured response plan.
This resulted in higher standby costs, reduced availability of equipment during genuine incidents, and a lack of clarity about which sites required support and why.
The organisation needed a review of its emergency power deployment so that decisions reflected real risk rather than outdated assumptions.
Our Approach
Vanta carried out a structured assessment of all locations that relied on standby generators.
The review focused on operational context rather than equipment first. We examined:
the original reason a generator was placed at each site
whether the current risk profile still justified standby provision
how often equipment had been used or tested
the operational consequences of failure at each location
the communication pathways during an outage
supplier engagement during emergency response
the time required to mobilise alternative equipment
This allowed us to build a clear picture of where standby support was essential, where it needed adjusting, and where equipment could be withdrawn without introducing operational risk.
We also worked with local teams to develop simple planning steps that made decision making during outages more consistent and more aligned with the true needs of each site.
The Impact
The review provided clarity that had been missing from emergency power planning.
Generator deployment was realigned with operational risk, and several units were removed or relocated.
Standby provision became more deliberate, and teams gained greater confidence in the decisions they were making during outages.
Key improvements included:
clearer understanding of which sites required standby provision
removal of equipment that added no operational value
faster response planning due to clearer decision pathways
improved supplier readiness for genuine emergency events
more balanced and predictable standby costs
The organisation now manages emergency power with a structured and informed approach that protects essential operations while reducing unnecessary spend.

The review helped us understand which sites genuinely needed standby support. Once we had that clarity, our planning improved and our response became far more consistent.
