The primary purpose of the midterm assessment is to check on the region’s progress in implementing the Seventh Northwest Power Plan, which the Council issued in early 2016. The Seventh Plan had many recommendations and the region has made significant progress in implementing the plan’s resource strategy. In the report we find that while some circumstances have changed since the plan was published, nothing calls into question the fundamental strategy described in the plan.
The Seventh Plan’s recommended resource program was, and remains, the preferred program under a wide range of circumstances. An in-depth examination of recent developments and comparisons to the forecasts made in the Seventh Plan confirms that the recommended resource strategy still produces a least-cost and reliable system, and the region will benefit substantially by continuing to implement the Seventh Plan. This assessment includes a review of the Action Plan (Chapter 4 of the Seventh Plan) and reports on plan implementation progress.
