Nevada Statewide Greenhouse Gas Emissions Inventory and Projections, 1990 to 2030

Emissions from existing units are estimated using averages of past emissions. One of the
problems with estimating emissions in this way is that a unit that has historically been underutilized has
the possibility of being used to capacity in the future to meet demand, which may result in
underestimated emissions.

While it is reasonable to assume that that some of the needed capacity from the retiring base-load coal-fired
facilities could be replaced with renewable generation, thereby further reducing the state's GHG emissions, the
business-as-usual cases presented by NV Energy do not make that assumption so it is not assumed here.
