The key steps in the plan included upgrading electrical capacity of the quarry to 27.6 kV, combining the quarrys electrical needs into one supply line, and running the new electrical line to the asphalt and crusher plants on the property.The first step in the process was to prepare a trench that would bury the new power line on the quarry property and run it to the plants, says Riley Sewell, materials field engineer in training (EIT) and project manager for the conversion. This approach reduces line strike power outages thatcouldoccurwithabovegroundpower linepoleson-site.Fromahealthandsafety standpoint, a below-grade electrical line reduces the risk of injury to workers. The trenching was completed in the fall of 2020 and jump started the continuing work on the project in the spring of 2021. The next step was bringing the new power line onto the quarry property. This was no easy task. The power source for the 27.6 kV service was on the other side of Highway 11 and at the other end of Rosewarne Drive, where the quarry is located. Completing this step included higher rated power poles, new metering, engineering and commissioning.Onceontheproperty,thenewlinewas fedthroughthetrenchandhookedupto thecrusherandasphaltplants.Anumberof electrical components were needed to complete WINTER 2022AVENUES 15'
