Washington State is the most populous state in the US’s Pacific Northwest region and
fosters a robust industrial, technology, and agrarian based economy that will lead
the state towards increasing electricity demand over the coming years. Considering
that most of the cost effective hydroelectric sources are tapped out and the state
will need to meet an RPS of 15% by 2020, wind power represents the largest resource
for renewable utility scale electricity. However, large-scale wind development is
synonymous with necessary balancing power to counteract wind intermittency. In order
to fully assess the emissions impact of integrating large scale wind power into Washington
State, this paper assumes a level of necessary natural gas balancing power to estimate
a range for the associated air emissions up to the year 2030.
Upon modeling the amount of electricity that can be generated from useful wind power
(>Class 3 sites) in Washington, results indicate that more than enough wind power
potential lies in the state to meet the RPS and demand up to year 2030. Meeting RPS
and demand for 2030 via wind would emit 30,856-113,074 metric tons of CO2. Furthermore,
although wind power is not a completely Carbon neutral generation source, this paper’s
analysis indicates that developing wind power to meet 2030 demand still has the potential
to abate 590,000-672,000 metric tons of CO2 emissions against a natural gas alternative,
in addition to meeting the state’s RPS.
