Resource Adequacy Advisory Committee

In 2013 the Council created the Resource Adequacy Advisory Committee (RAAC), which replaces the Resource Adequacy Forum, an ad-hoc committee created in 2005 to assess the adequacy of the Northwest’s power supply. The RAAC now performs this function as an advisory committee to the Council. In 2011, the Council adopted its current adequacy standard, which limits the likelihood of a supply shortage (more commonly referred to as the loss of load probability or LOLP) to a maximum of 5 percent.   

This adequacy assessment is intended to be an early warning should resource and energy efficiency acquisitions not keep pace with load growth. However, an LOLP assessment greater than 5 percent for 2019 and 2021 does not mean that the region has failed to maintain an adequate supply. What it does mean is that some combination of new generating resources and demand-reduction programs are needed to keep up with changing demands and plant retirements. 

The Council's adequacy assessment is updated annually.  The latest edition can be found on the right hand side of this page.
