EDIST 2021 - CVR and Grid Edge Technology as a Non-Wires Alternative for Capacity Reduction
/Abstract: By combining CVR (Conservation Voltage Reduction) with grid-edge power-electronic technology, Hydro Ottawa is targeting a demand reduction of 1.2 MW or 2.4% of substation peak load at Kanata MTS substation. The project currently includes 43 pole mount ENGO® devices, manufactured by Varentec, to support up to 6% voltage reduction at the station LTC. The ENGO™ devices boost low-voltage outliers above CSA minimums, enabling demand reduction, energy savings and improved power quality without customer impact or participation. Project cost and complexity make CVR attractive compared to other non-wires alternatives to offset demand and reduce or defer capital investments on lines and stations
