Gremalco Pty Ltd is now one of the largest electrical sub-transmission and distribution contractors in NSW and is primarily engaged in the delivery of electrical infrastructure up to 132kV on greenfield projects, refurbishments and upgrades of existing infrastructure and asset relocations. We have built an in-house capability to successfully deliver both overhead and underground electrical infrastructure for these project types.

The Smart Evolution 

In recent years, the smart evolution of Gremalco has continued with many of our industry’s best project managers, supervisors, leading hands, operators, linesman and jointers joining our ranks. Our project outcomes are seen as some of the highest quality delivered in our field.

Every industry has its challenges finding skilled staff in remote locations. Gremalco rose to this challenge by engaging the best ASP1’s across metro and regional NSW as part of their labour hire network. Our flexible resource pool provides a cost effective solution for regional works while maintaining consistent project outcomes under Gremalco's Project Management, Supervision and Systems.
