Current through Register Vol. 54, No. 49, December 7, 2024
Section 69.3553 - Electric vehicle charging rate design(a) To promote efficient use of electric-vehicle charging infrastructure and to manage electric grid demand, public utilities should consider variable rates for electric-vehicle customers based on the time of day and the level of demand on the electric grid. This means that electric-vehicle charging rates should be higher during peak demand hours and lower during off-peak hours. The Commission recommends that electric distribution companies develop electric-vehicle distribution rates with cost-of-service principles that incentivize increased network capacity utilization of the distribution system. Electric distribution companies should also take into consideration rates for direct current fast chargers, including demand charges, to manage electric grid stress during peak hours. The Commission also recommends that electric distribution companies develop electric-vehicle charging default service generation rates that, at a minimum, properly reflect the cost of generation services during times of system stress. These default service generation rates may include use of time-of-use rates that use on- and off-peak periods which appropriately incentivize the movement of charging consumption to off-peak periods or periods of less system stress. (b) The Commission recommends that electric-vehicle charging distribution and default service generation rates should be flexible and adaptable to changing circumstances and technologies. As such, electric-vehicle charging distribution and default service generation rates should be periodically reviewed and adjusted, as necessary, to ensure that they remain fair, cost-effective and efficient.Adopted by Pennsylvania Bulletin, Vol 53, No. 51.
