Before a utility extends or modifies its transmission facilities to a retail customer, the utility shall require a contract between the utility and the customer which describes the facilities to be constructed, lists the cost of construction, apportions the responsibility for the construction costs between the utility and the customer and provides a supporting analysis for the construction and the cost apportionment. The utility shall submit the contract to the commission for approval. The commission shall review the contract to assess whether existing ratepayers would be adversely affected by the proposed extension or modification. If the commission does not respond to the utility within 20 working days from the date of receipt, the contract is approved.
