Electric Supply Charge This form details delivery charge adjustment and electricity charge by load zone, service class, and voltage delivery level.
  • For customers without interval meters, the actual price that a customer will see on their bill will be a 30-day load shape weighted average. In other words, we will develop a 30-day weighted average kilowatt-hour cost by averaging the prices for each hour of each day in the 30-day period. For example, if your meter is read on March 29, your weighted average price would be based on the previous 30 days' prices.
  • These prices are the actual prices given current market and weather conditions experienced since September 1, 1998. These prices are not a forecast of where we believe prices will be tomorrow or any time in the future.
