Pollution Prevention and Reduction

Carbon Dioxide

As the nation’s largest power company, TVA delivers reliable and competitively priced power to 155 local power distributors, 52 large industrial customers and seven federal installations.

These customers are interested in the CO2 intensity of the power they’re buying. In addition, many stakeholders are interested in comparing the CO2 performance of various electric utilities of different sizes.

As a service, TVA provides as-delivered CO2 emission rates to its customers and stakeholders in a manner consistent with generally accepted carbon accounting standards, such as The Climate Registry’s Electric Power Sector Protocol for the Voluntary Reporting Program and the new World Resources Institute and World Business Council for Sustainable Development’s Greenhouse Gas Protocol’s Scope 2 Guidance.

About TVA-specific CO2 lbs/MWh emission rates

TVA’s local power company 2014 average as-delivered (Scope 2) CO2 emission rate was 1,045.81 lbs/MWh. Consistent with generally accepted voluntary carbon accounting standards, this emission rate reflects TVA's renewable energy credit adjustment, which resulted in an reduction of 5.59% in the as-delivered CO2 lbs/MWh rate.

TVA recognizes that carbon footprint performance can be a critical factor in customer decisions. We are happy to provide carbon data and opportunities that may allow further reduction of their carbon footprint. If needed, TVA’s power representative will assist them in reviewing CO2 accounting and reduction options, including baseline CO2 lbs/MWh emission rates.

The current EPA eGRID (Year 2010) national CO2 lbs/MWh rate is 1,232.35 and regional CO2 rate is 1,389.20. These rates as well as the rates for other regions of the United States can be found here. Carbon accounting users will still need to quantify their Scope 2 emissions associated with electricity use for CH4 and N2O using their choice of default factors for these gases.
