Rider 34

In February, the Illinois Commerce Commission approved Rider 34, Supplier Firm Transportation Service. This rider allows suppliers to form groups of up to 150 Rider 25 customers that are not commonly-owned, similar to the provisions of Rider 13 for Rate 74, 75, 76, and 77 accounts. However, customers in the group would still be cycle (meter) read once a month and not daily balanced. Under the rider, the supplier would have a monthly group charge and assume the responsibility (costs) for purchasing any company-supplied gas, Excess Storage charges, any applicable OFO provisions etc., plus any applicable taxes. Rider 34 is completely optional. Rider 25 as it exists today will still be available for individual customers and commonly-owned groups. Nicor Gas’ tariff Rider 34 can be accessed in the company’s rate book.
