Located in one of the sunniest places in Canada and in a province historically known as one of North America’s major centres for oil production, the project features a 21 MWp solar array coupled with an 8.4 MWh VFB vanadium flow battery . A Canadian first in terms of size and application, this project will now generate enough dispatchable, low-cost, low-carbon electricity to serve the needs of over 7,000 Alberta residents with clean, on-demand solar power and is targeting carbon savings of approximately 20,000 tCO2e per year. 

The Chappice Lake Solar Project is a 21 MW (AC) solar generation project located along Township Road 150 and approximately 26 km northeast of Medicine Hat, Alberta, Canada. The power plant (21 MW, 0.93 PF consuming VARs) is interconnected to a distribution feeder and includes a 25 kV collection system interconnected to FortisAlberta distribution line that will transport power from the Project to the 25 kV distribution feeder 649S-2058L at Altalink’s 649S Chappice Lake substation.

The solar project will be built using LONGi bifacial PV modules (545 W). along with a battery energy storage system (BESS) consisting of 8.4 MW of IES’s Vanadium Flow Batteries (VFB) for energy shifting. Four (4) SMA SC4200-UP central inverters will convert 1,500 VDC voltage to 630 VAC and a step-up transformer installed at each inverter skid will elevate the voltage to 25 kVAC. The total output from the inverters will be limited to generate a maximum of 21 MW (AC) at the point of common coupling (PCC).
