Efficient Power launches new mobile industrial substations

Mobile substations are not a new concept, but according to Warwick Jackson, managing director of Efficient Power, these were previously built largely for the wrong reasons and in the incorrect types of structures.

As the construction of brick substation buildings in remote locations comes with a slew of challenges, including stringent health and safety regulations, access issues, poor productivity, high costs and other logistical concerns, Jackson realised that the answer to the challenges of building traditional substations on site was to create fully integrated structures off-site.

"Traditionally, substation construction is always going to be complicated, costly and time consuming, requiring a large team of expensive specialists to be brought to the site to complete the fitting and testing of all equipment. This comes at great cost and risk, and completion of the project hinges on the reliability of each of these specialists," says Jackson.

Bespoke products

In contrast, the Efficient Power solutions are bespoke products designed and built according to exact specifications, around all the equipment they house. The complex mega buildings should also outlive the equipment they were built to house.

The launch of the new mobile industrial solutions was made possible through Efficient Power's alignment with Efficient Engineering, allowing it to utilise specialist skills from several unrelated industries, bringing together heavy engineering and fabrication with a project execution and technical team to custom design each element of the structure.

By working with a trusted design and engineering house on a 1,800m³/hour pump station, the company could consult with professional engineers who understood both vibration and thrust issues, and could design solutions to accommodate them.

Operational within a week

"This approach genuinely makes it possible to have a large pump station or substation - equipped with medium voltage switchgear, a motor control centre, and a control and instrumentation room - fully operational within a week of arriving on site. Once fabricated, the mobile building needs to be equipped, with every possible piece of equipment commissioned in the same facility, and test-integrated so that the building is 100% operational before being relocated," explains Jackson.

The completed structures are then transported to site, where they are hydraulically lifted and positioned onto custom-built plinths where racking and cable work can simply be connected, resulting in a substation ready to provide more than thirty years of service. The entire process is accomplished in a fraction of the time it would take to construct on-site.
