The Energy Office shall provide written notification to each applicant approved to receive a program rebate. Such notice shall set forth the terms and conditions under which the program rebate is to be made.

(b) The commitment shall remain in effect for a maximum of 12 months following its issuance, during which time the project must be completed. The Energy Office for good cause may extend the term of the commitment. As used herein, good cause means an unanticipated circumstance or event which, despite the due diligence of the applicant, renders compliance with such 12-month term impracticable.

Rebate commitments generally or with respect to specific categories of applicants shall be subject to the availability of program funds appropriated by the New York State Legislature.

The rebate recipient is expected to adhere to the scope of work for the project as reviewed and approved by the Energy Office. The rebate recipient shall promptly provide written notice to and obtain written approval from the Energy Office for any changes in energy conservation improvements to be implemented which differ from the notice of rebate commitment issued by the Energy Office. Under no circumstances will payment be made by the Energy Office for work not approved by the Energy Office.
