At 9.3 megawatts, and woven together with more than 300 kilometers of electrical wire on an 80-acre site, Erie Ridge Solar Electric System is the first utility scale, single-axis, ground mount tracking system in Ontario. Project highlights include 120,000 cubic yards of dirt moved; survey and placement of 11,000 posts; 955 125-foot-long rows of solar panels created; 34,000 solar panels installed; 300 kilometers of wire pulled; nine electrical inverter stations (DC to AC converters) constructed. The system is able to generate almost 10 megawatts of alternating current back to the grid --- enough to power almost 1,500 homes.
PCL used schedule acceleration techniques, such as prefabrication of the inverters, which convert the electricity generated from DC to AC, in order to maintain the client’s schedule. The sheer volume of material required an extensive material handling system, which involved day-to-day meetings and scheduling “just in time” deliveries to maximize efficiencies. Also due to the sheer volume of product, a well-organized and progressive commissioning schedule was created.
This project was delivered as part of the Renewable Energy Standard Offer Program, created to help Ontario meet its renewable energy supply target.
