4. Next Steps

Energy Division staff will calculate the MPR for 2008 and later years based on the methodology set forth in this decision and present it annually, as in previous years, in the form of a draft resolution. Where the decision provides guidance to staff about the use of specific inputs, staff should consider that guidance, but staff retains its discretion to choose inputs to the MPR model that most appropriately reflect the Commission's market-based approach to implementing the model.

With respect to the inputs to the 2008 MPR, staff has available all the party comments submitted prior to this decision. With respect to the inputs to the MPR model for 2009 and later years, staff has discretion to seek comments and other participation from the parties prior to, as well as after, preparation of the draft resolution calculating the MPR for that year. The assigned Commissioner or assigned ALJ in R.08-08-009 or its successor is authorized to issue any rulings necessary to allow effective participation of the parties in developing the inputs to be used for the MPR model in 2009 and later years.

We do not expect to revisit the MPR methodology again in the context of the current RPS program. If there are future legislative changes to the MPR, we will take steps to conform the MPR promptly to any new legislative mandates. If significant new state, regional, or national developments impact the determination of GHG compliance costs for the MPR, we will review that aspect of the MPR methodology as appropriate.
