The Challenge
Silent power for portable offices.
One of the largest utility companies in New Zealand was on a mission to rewire high voltage powerlines in a remote area of the North Island. The job took months to complete and required setting up portable powered offices. The customer sought a cost-saving solution that would also minimize noise on site and create a welcoming working environment for the team of high voltage electricians.
To meet these requirements, they turned to Portacom, a market-leading supplier of modular buildings across New Zealand. Portacom collaborated with Aggreko to deliver portable offices powered with a combination of a diesel generator and battery energy storage (BESS).

The Solution
Battery storage system backed up by a generator
To meet the customer's requirements, Aggreko sized the generator and battery storage according to the power needs on site. They provided a 60kVA generator and a 45kVA battery.
As portable offices require a moderate amount of power, the battery was intended to do the bulk of the job, with the generator only used to trickle charge the battery after hours. A redundancy system was in place to ensure
“The buildings on our handover were all up and running with no noise. Last year there was continuous noise 24/7 with the generator running to power the buildings. Now other than the general work noises, we can enjoy the environment we are working in, it’s an amazing little spot. The set up also supports our Health Safety and Environment initiatives.”
