Systems 20 kW or Less AC

The customer shall be billed monthly on a net energy basis. When the energy produced exceeds energy consumed for the billing month, the customer shall be credited for the excess energy volumes at the applicable Avoided Cost Rate(s) identified in the Energy Rates Payment section of Schedule No. Pgs-2.

If, in any month, the customer’s bill has a credit balance of $25 or less, the amount shall be credited to subsequent bills until a debit balance is reestablished. If the credit balance is more than $25, the utility shall reimburse the customer by check upon request. Monthly credits shall be computed by taking the net excess kilowatt-hours produced times the sum of the applicable Energy Charge or Avoided Cost Rate(s).
