How is the inclining block schedule designed?

During the months of June through September, members who use 800 kWh or less will be charged 6.380 cents per kWh, while those who use over 800 kWh will be charged 9.024 cents per kWh. Billing during the months of October through May will be the same regardless of use, at 6.380 cents per kWh. This change encourages conservation and energy efficiency among the membership, which can help reduce total cost and offset the fixed consumer charge.
