As part of our extensive Planned Preventative Maintenance (PPM) schedule at our Centro datacentre facility, we run start tests on our generators every two weeks.

These generators provide stand-by power in the unlikely event of a utility outage on both HV supplies to the datacentre. We store enough diesel on-site to run the entire facility for around 4 days, and we have fuel resupply agreements with multiple fuel providers to ensure we can continue operating from generator power even in case of a prolonged outage.

We posted an image of the snow that had settled at Centro over on our Twitter page (over a foot deep in most places!), but as a generator start test was scheduled for today, we’ve uploaded the CCTV footage as an extra bonus:

Our generators are constantly heated and their starter batteries kept fully charged to ensure they are available as quickly as possible to provide backup power to our facility.

During this start test, the outside temperature was around -1C, and both generators started, synced and closed their breakers on to our main switchgear in 18 seconds, well within normal operating tolerances (we have battery supplies for our UPS system to last around 10 minutes before the generators kick in). The generators are run for around 30 minutes, during which time the on-board management computers are checked to ensure that there are no faults.
