NC-2009 EAc1:Optimize Energy Performance

Cost Savings from an Owner PPA

If an owner constructs a remote net-metered PV system as part of a power purchase agreement (PPA), can the PPA cost savings be used to increase the efficiency (cost) savings vs. the baseline model (EAc1)? (With the assumption that the baseline model would use the "normal" purchased utility electric rate.) The new building project and the off-site PV system would be constructed along similar schedules, but not part of the same project scope.

No. You don't pay a penalty if it goes the other way either. The rates must be the same in both models and the renewable energy is counted based on the virtual rate from the proposed energy model. You can use the PPA rate but you would have to do so in both models.

Thanks Marcus. But if we proceed with some portion of an on-site PV system, does the on-site portion of the PV system also need to be accounted for in the base model, or can we utilize the energy cost savings to increase the number of points achieved in this credit.

Nope. No PV in the baseline and you get to count the cost savings toward your EAc1 points.
