Commercial BESS in Calgary

Commercial buildings in Calgary are served by ENMAX Power. Alberta's energy-only pool exposes C&I sites to volatile hourly pool prices, while distribution and transmission (DTS/rate rider) charges are billed on monthly billing demand. BESS value stacks arbitrage against pool price volatility with demand-charge avoidance.
