The challenge

Upgrade remote substation with zero outages

The local utility commission mandated that the utility company take ownership of a neglected substation in a remote location. Significant upgrades were required in a 3 week period while still keeping customers powered. Work would need to be carried out at an extremely remote location across a 200km ice road, in -40°C temperatures.

The System had to be designed to operate continuously with the 25kV line infrastructure and have the necessary field experience to install, operate and maintain the equipment. Expertise was essential to meet protection and control requirements, manage fuel logistics, and provide remote monitoring.

The solution

Right sizing equipment to provide the right amount of power

Our team provided a medium voltage power solution with N-1 redundancy for the 18 day period of upgrade work to ensure that the utility’s customers had power throughout. We also arranged the logistics for equipment and fuel to cross the ice roads, and arrive safely to the remote project site.

Overseeing the successful installation into the 25kV distribution line, our experts also setup our Aggreko Remote Monitoring (ARM) services. Remote monitoring allowed the customer to limit physical presence on a remote project site, but still an eye on equipment and power on.

The impact

Millions of interruption minutes eliminated

The project was successfully delivered on time and the customer had no outages at all during the upgrade work, which meant they were able to keep the lights on for their own customers.

We used our remote monitoring service to anticipate any potential problems, saving the utility company time and resources.

As a result the utility eliminated 3.5 million Customer Minutes of Interruption (CMI) and were able to complete the upgrades to their substation before the ICE road melted.

Thanks to the careful planning and execution of Aggreko experts there were zero EHS incidents during the project.

“At Aggreko we provide companies strategies to safeguard both their profits and the environment while keeping the operations running at full capacity."
