•If the Commission approves an increase to the PL-TOU SL 2 rate as recommended by this Joint Stipulation, the peak energy rate of TOU shall be increased more than the demand charge is increased, and the cost recovered through the on-peak energy charge shall be higher than the cost recovered through the PL Standard SL 2 energy charge.

•If the Commission approves an increase to the PL-TOU Service Level 5 rate as recommended by this Joint Stipulation, then any such increase shall only be applied to the demand charge. The energy charge shall remain unchanged.

•Modifications to OG&E’s Terms and Conditions of Service and Tariffs proposed by OG&E in its Direct Testimony shall be approved unless otherwise amended by this Settlement Agreement.
