State curtailment directives apply to all retail loads served within the state of Washington. Under this plan, curtailment is requested or ordered as a percentage of historical, base billing period electric energy consumption, weather normalized at the discretion of each utility, for all individual residential, general, and major use consumers in the state of Washington. Curtailment stages are associated with increasing energy deficits, and are therefore likely to be implemented in a sequential manner, however, circumstances may require nonsequential implementation.
The five curtailment stages are:
Curtailment
Stage # | Nature | Percent | Type of Curtailment |
Stage 1 | Voluntary | No specified % | Uniform among all consumers |
Stage 2 | Voluntary | 5%+ | Uniform among all consumers |
Stage 3 | Mandatory | 5 to 15% | Uniform among all consumers |
Stage 4 | Mandatory | 15% | Residential consumers |
15%+ | General use consumers |
15%+ | Major use consumers |
Stage 5 | Mandatory | % associated with Stage 4+ additional curtailment | Continued consumer curtailment plus utility action, including plant closures and possible black-outs |
