Reducing Carbon Emissions
Over the past two decades, Dominion Energy has made significant changes to its overall generation mix. Guided by the complimentary principles of balance and diversity, we have:
- added new low- and non-emitting generating resources, such as solar power;
- achieved sustained efficiency improvements at existing power stations;
- retired a number of aging coal units;
- converted other coal units to cleaner natural gas and biomass facilities;
- evaluated license extensions for existing nuclear units; and
- expanded the range of energy conservation and efficiency programs for our customers.
Together, these initiatives have helped us to reduce and avoid additional carbon emissions while remaining a reliable, low-cost energy provider. In fact, Dominion Energy continues to produce fewer carbon emissions per unit of energy than almost three-fourths of the nation’s 100 largest power producers.
According to the 2015 “Environmental Air Emissions Benchmark Report” published by MJ Bradley & Associates, our company ranks 26th on the list of the 100 largest power producers in the U.S. based on emissions intensity (pounds per megawatt-hour of output). The 2015 report uses 2013 generation and emissions data.
Comparing 2015 to 2000, we have reduced the total volume of carbon dioxide emissions of our generating fleet by 21 percent. Over the same period, we have cut our carbon intensity rate – the average CO2 emissions rate per unit of electric output – by 43 percent, even as the level of electric generation increased by 37 percent.
Improving the generating efficiency of our utility fleet has been a strategic focus over the past decade. Efficiency improvements allow us to squeeze more power out of our units while using roughly the same amount of fuel – and avoiding additional atmospheric emissions – a plus for our customers and for the environment.
