ALLOWABLE INVESTMENT 4.1 The Allowable Investment for Services and Mains is determined by first calculating the estimated annual therm usage and then applying the Allowable Investment Factor per therm. 4.2 The estimated annual therm usage is calculated as follows: (a) For residential applicants: When natural gas is the primary heat source, calculate the estimated annual space heating therm usage by multiplying the square foot factor of 0.234 by the square footage of the home. To the estimated annual space heating therm usage, add gas appliance annual therm usage estimates from the chart below, as applicable, to calculate the total estimated therm usage per year. Gas appliances not on this list can be estimated by the Company on a case-by-case basis. In residential Developments where specific appliances are unknown at the time of calculation, the Company will base therm estimates on only the estimated annual space heating therm usage plus the water heater therm estimate.

DEFINITION OF TERMS 9.1 Abandonment – A service that is being discontinued at or near the main, when service is not expected to be reactivated. If there is less than two (2) feet of service extending from the tee, it is considered an abandonment. If the service line is left on the property and the active footage exceeds two (2) feet, it is referred to as “abandoned to stub.” 9.2 Allowable Investment – The portion of the cost of Gas Facilities funded by the Company (see Section 4 for Allowable Investment amounts). 9.3 Allowable Investment Factor – A factor derived from the Present Value (PV) of the embedded cost of Mains and Services in the Company’s approved tariff. The PV calculation uses the IPUC approved Weighted Average Cost of Capital as the discount rate over the life of the plant. Allowable Investment Factors for Service and Main are calculated separately (see Section 4.3). 9.4 Applicant – A person or entity requesting the Company to provide new, relocation or abandonment of Gas Facilities. 9.5 Company Betterment – The portion of the cost estimate for the extension of Gas Facilities that provides a benefit to the Company, but is not required by the applicant, based on the applicant’s estimated gas load.
