(C) A determination by the commissioner concerning an application submitted pursuant to this subdivision is not a binding commitment to allocate the estimated number of allowances from the EERESA to the Proponent after such project initiates operation.

(7) In 2010, the commissioner may conduct a review of the Energy Efficiency and Renewable Energy Set-Aside Allocation program, including, but not limited to, the following factors:
