(e) "Natural gas extension project" or "project" means the construction of new infrastructure or upgrades to existing natural gas facilities necessary to serve currently unserved or inadequately served areas.
(f) "Revenue deficiency" means the deficiency in funds that results when projected revenues from customers receiving natural gas service as the result of a natural gas extension project, plus any contributions in aid of construction paid by these customers, fall short of the total revenue requirement of the natural gas extension project.

(a) A public utility may petition the commission outside of a general rate case for a rider that shall include all of the utility's customers, including transport customers, to recover the revenue deficiency from a natural gas extension project.
(b) The petition shall include:
(1) a description of the natural gas extension project, including the number and location of new customers to be served and the distance over which natural gas will be distributed to serve the unserved or inadequately served area;
(2) the project's construction schedule;
(3) the proposed project budget;
(4) the amount of any contributions in aid of construction;
(5) a description of efforts made by the public utility to offset the revenue deficiency through contributions in aid to construction;
(6) the amount of the revenue deficiency, and how recovery of the revenue deficiency will be allocated among industrial, commercial, residential, and transport customers;

(a) The commission shall allow opportunity for comment on the petition.
(b) The commission shall approve a public utility's petition for a rider to recover the costs of a natural gas extension project if it determines that:
(1) the project is designed to extend natural gas service to an unserved or inadequately served area; and
