Quebec Commercial & Industrial BESS

Hydro-Québec Rate M and Rate L bill power demand (puissance appelée) monthly, and winter peak events (décembre–mars) carry the highest system stress. Energy is inexpensive, so BESS economics are driven almost entirely by demand management and winter peak credits.
