Electricity Use Analysis Quantified Unexpected Savings and Losses
GreenQ Partners analysed electricity consumption at Ready Bake Mississauga, an industrial refrigeration facility operated by Weston Foods. We used utility bill data to confirm the effects of technological and operational changes in electricity use. As usual, we used weather data provided by NASA.
We identify savings in kWh. To convert saved energy to dollars we were forced to use an average cost per kWh. This limitation was imposed by currently available usage data. Since higher consumption at a refrigeration facility coincides with higher daytime rates, actual dollar savings are even higher.
Two surprising findings of this analysis were that (a) up to 90% of electricity used at an industrial food refrigeration facility were actually not related to weather, and (b) hiring a new general manager may turn out to be as financially effective as performing a lighting retrofit.
