Source: Northwest Power and Conservation Council. Note: Hardin is idle, but has not been retired.
Planned retirements in the Pacific Northwest region exceed 3,600 MW and the
Northwest Power and Conservation Council forecasts regional capacity shortfalls as early
as 2021. NorthWestern's continued reliance on the market to purchase energy to fill
the gap during peak customer demand will significantly increase price and reliability risk
for North Western's customers because of the reduced energy supply availability.View entire presentation
