Material Changes and Regulatory Actions
The OPUC issued an order on October 16, 2020, approving a Comprehensive Settlement that concluded the general rate case. This settlement incorporates a prior agreement on cost of capital issues. The order also extends the decoupling calculation period to include April, alongside November and May, to encourage energy conservation without penalizing earnings for volume reductions. The filing notes that current bills are approximately 37% lower than 15 years ago due to lower commodity costs and efficiency measures.
