Ind. Code § 8-1-2.4-4 – Electric and steam utilities required to enter into purchase contracts; rates for new and existing facilities; utilities not required to construct additional facilities or distribute power from priv

(a) Subject to section 5 of this chapter, the commission shall require electric utilities and steam utilities to enter into long term contracts to:
1. (1) purchase or wheel electricity or useful thermal energy from alternate energy production facilities, cogeneration facilities, or small hydro facilities located in the utility's service territory, under the terms and conditions that the commission finds:
  1. (A) are just and economically reasonable to the corporation's ratepayers;
  2. (B) are nondiscriminatory to alternate energy producers, cogenerators, and small hydro producers; and
  3. (C) will further the policy stated in section 1 of this chapter; and
2. (2) provide for the availability of supplemental or backup power to alternate energy production facilities, cogeneration facilities, or small hydro facilities on a nondiscriminatory basis and at just and reasonable rates.
(b) Upon application by the owner or operator of any alternate energy production facility, cogeneration facility, or small hydro facility or any interested party, the commission shall establish for the affected utility just and economically reasonable rates for electricity purchased under subsection (a)(1). The rates shall be established at levels sufficient to stimulate the development of alternate energy production, cogeneration, and small hydro facilities in Indiana, and to encourage the continuation of existing capacity from those facilities.
(c) The commission shall base the rates for new facilities or new capacity from existing facilities on the following factors:
1. (1) The estimated capital cost of the next generating plant, including related transmission facilities, to be placed in service by the utility.
2. (2) The term of the contract between the utility and the seller.
3. (3) A levelized annual carrying charge based upon the term of the contract and determined in a manner consistent with both the methods and the current interest or return requirements associated with the utility's new construction program.
4. (4) The utility's annual energy costs, including current fuel costs, related operation and maintenance costs, and any other energy-related costs considered appropriate by the commission.
(d) The commission shall base the rates for existing facilities on the factors listed in subsection (c). However, the commission shall also consider the original cost less depreciation of existing facilities and may establish a rate for existing facilities that is less than the rate established for new facilities.
(e) In the case of a utility that purchases all or substantially all of its electricity requirements, the rates established under this section must be equal to the current cost to the utility of similar types and quantities of electrical service.
(f) In lieu of the other procedures provided by this section, a utility and an owner or operator of an alternate energy production facility, cogeneration facility, or small hydro facility may enter into a long term contract in accordance with subsection (a) and may agree to rates for purchase and sale transactions. A contract entered into under this subsection must be filed with the commission in the manner provided by IC 8-1-2-42 .
(g) This section does not require an electric utility or steam utility to:
1. (1) construct any additional facilities unless those facilities are paid for by the owner or operator of the affected alternate energy production facility, cogeneration facility, or small hydro facility; or
2. (2) distribute, transmit, deliver, or wheel electricity from a private generation project.
