Business, commercial/industrial, and farm/ag customers
Non-residential customers taking service under Second Nature may nominate any monthly dollar amount of participation in the program. This contribution toward the costs of renewable energy will be added to the customer's normal monthly bill.
Non-residential customers will pay the actual energy cost adjustment on their monthly utility bills, but they will receive a billing adjustment for participating kilowatt-hour purchases if the actual energy adjustment on their monthly bills is greater than the fixed Second Nature energy adjustment, which will be recalculated on an annual basis with the most recent actual 12-month period of energy costs.
