Optimal Modeling of Integrated Energy Demand Response under Time …
Peak-valley time-of-use tariff is an effective price-based demand response strategy. Through reasonable time-of-use tariff, energy demanders can provide sufficient and efficient price signals, so as to achieve the goal of peak-filling of energy demand. The integrated energy system combines electricity, heat, cold, gas and other energy forms, …

Managing costs with Time-of-Use rates | Ontario Energy Board
Electricity Time-of-Use rate periods. Time-of-Use rates are different depending on when you use electricity. There are three periods: Off-peak, when demand for electricity is generally lower. Ontario households use most of their electricity – nearly two thirds of it – during off-peak hours. Mid-peak, when demand for electricity is moderate.
