C.R.S. § 40-2-139: Investor-owned utility electric resource planning - maximum discount rate authorized.

If the commission relies on the use of a discount rate when calculating net present value of future carbon-based fuel costs in an electric resource plan, the discount rate must not exceed the long-term rate of inflation, as determined by the commission. In determining the long-term rate of inflation, the commission shall determine an appropriate rate of inflation specifically for fuel costs.
