(a) A RESP Borrower may provide financing to Qualified consumers to implement or invest in one or more set of EE measures such as those listed in this section.

(b) A RESP borrower may be able to provide financing to Qualified consumers for EE measures not listed in this section, if it can justify, to the satisfaction of the Administrator, that the proposed EE measure is consistent with the RESP statute, is cost effective, and the technology is commercially available. The Administrator must make the determination prior to the borrower implementing the EE measure.

(c) A RESP applicant with an existing EE Program as of April 8, 2014, may submit the list of the EE measures used in its program to RUS for validation and approval. The Administrator will make a finding as to whether such EE measures are consistent with the purpose of RESP.

(d) A RESP borrower, subject to the Administrator's written approval, may modify the list of EE measures if those measures are consistent with the statutory purpose of RESP.

(e) RESP loan proceeds must finance EE measures for the purpose of decreasing energy usage or costs of the Qualified consumer by an amount that ensures, to the maximum extent practicable, that the loan term will not pose an undue financial burden on the Qualified consumer.
