The temporary shutdown of Mohave results in a 38% decrease in emissions from 2005 to 2006. From 2006 to 2020, the emissions from Nevada electricity generation are projected to grow at 2.3 percent per year, lower than the growth in electricity generation, due to an increased fraction of generation from renewables and natural gas. The GHG emission intensity (emissions per MWh) of Nevada electricity is expected to decrease from 0.66 MtCO 2 /MWh in 2005 to 0.53 MtCO 2 /MWh in 2006. The intensity then continues to decrease, at a slower rate, to 0.46 MtCO 2 /MWh in 2020. Nevada Division of 26 Center for Climate Strategies Environmental Protection www.climatestrategies.us
FINAL Nevada GHG Inventory and Reference Case Projection CCS, July 2007 Figure A5. Nevada GHG Emissions Associated with Electricity Production (Production- Basis) MMtCO2e 30 25 20 15 10 5 Coal Natural gas Petroleum 0 1990 1995 2000 2005 2010 2015 2020 Source: CCS calculations based on approach described in text. As described above, the net-consumption based emissions for Nevada were estimated by first accounting for the emissions associated with exports from the Mohave power plant. Figure A6 shows Nevada electricity demand and the generation from Nevada power plants, excluding Mohave exports. Note that the State’s electricity demand exceeds the generation from in-state resources in each year. Compared with Figure A4, the decreased generation resulting from the temporary shut down of the Mohave at the end of 2005 is hardly noticeable as projected increases in generation from new natural gas plants compensates for the lost in-state electricity from Mohave.
