Main line extensions will be made by UniSource Energy Services (UES) at its expense for the allowable investment as calculated by an Incremental Contribution Study (ICS).
UES, after conducting an ICS, may at its option, extend its facilities to customers whose usage does not satisfy the definition of economic feasibility, provided the customer signs an extension agreement and advances the company the funds necessary to make the extension economically feasible. Applicants may provide the trench for service lines and/or mains to UES' specifications to reduce the advance required.
Customers provided with line extensions using the Incremental Contribution Method shall be reviewed annually for a period of five years to determine the amount of any refund.
