Customer A Customer B 50kW load for 50 hours: 5kW load for 500 hours:
Usage Usage Energy = 50kW x 50 hours = 2,500kWh Energy = 5kW x 500 hours = 2,500kWh Demand = 50kW Demand = 5kW
Bill Bill Energy = 2,500kWh x $0.15 = $375 Energy = 2,500kWh x $0.15 = $375 Demand = 50kW x $10.00 = $500 Demand = 5kW x $10.00 = $50
Total = $875 Total = $425
May 12, 2018 Slide 19 Electrification of bus fleets: Grid Impacts and Solutions Impact of power demand charge
• Energy charges are associated with the costs of generating electricity • Demand charges are associated with the distribution of electricity • The challenge is to manage adequately the power demand which may result in costs to improved existing infrastructure • For the consumer, decreasing the peak demand will decrease demand charges
May 12, 2018 Slide 20 Solutions to grid impacts: Smart charging Control charging of buses: • Rates from utility • Bus schedule • Limit maximum power
Connected • Fleet management Services • Performance reporting • System integration Fleet Charger Operation Management
• Hardware and software checks • Charge(r) remote support • Charge(r) maintenance Solutions to grid impacts: Battery Energy Storage Peak Shaving with Battery Energy Storage
Description – Peak shaving stores power during periods of light loading on the system and delivers it during periods of high demand for the purpose of reducing peak demand for the electricity consumer Response time – Short duration application that requires ability for fast discharging (generally measured in minutes) Benefit – Customers can save on their utility bills by reducing peak demand charges – Utilities can reduce the operational costs meeting peak demand
