Summary: Revises Tariff WN U-76, Schedule 70 (Renewable Energy Rider – Optional) and Schedule 73 (Renewable Energy Rider – Optional Bulk Purchase Option), decreasing the size of renewable energy blocks under the Blue Sky Program from 200 kilowatt-hours (kWh) to 100 kWh per block. This change passes through the increased cost of renewable energy credits to the customer, and increases the voluntary cost for a customer to fully offset its energy usage with renewable energy.
