Commercial BESS in Toronto

Commercial buildings in Toronto are served by Toronto Hydro. Global Adjustment dominates C&I electricity cost. Class A customers (peak demand ≥ 1 MW, or ≥ 500 kW in eligible sectors) are billed GA on their share of the five IESO coincident system peaks, making peak-hour dispatch the single largest BESS value driver. Class B customers see GA as a volumetric charge and monetise BESS mainly through LDC demand charges.
