Carbon Dioxide

TVA's 2023 system Carbon-emission rate of 624.94 lbs/MWh. This rate includes emissions and generation from TVA generating assets and purchased power. The CO₂ rates disclosed reflect TVA's 2023 renewable energy credit (REC) adjustment, which resulted in a reduction of 2.76  percent in the CO₂ lbs/MWh. For formal disclosure of customer CO₂ rates appropriate for carbon accounting purposes, please contact TVA or your local power company directly.

As the nation's largest public power company, TVA delivers reliable and competitively priced power to 153 local power distributors, 54 large industrial customers and seven federal installations.

These customers are interested in the CO₂ intensity (or "carbon footprint") 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 2023 system carbon-emission rate of 624.94 lbs/MWh. This rate includes emissions and generation from TVA generating assets and purchased power.

Consistent with generally accepted voluntary carbon accounting standards and in response to customer requests, TVA annually allocates actual CO₂ emissions to customers in the same manner as it allocates costs.

Formal disclosure of customer CO₂ rates appropriate for carbon accounting purposes can be found under the Current Rates & Disclosures button.

The CO₂ rates disclosed reflect TVA’s 2023 renewable energy credit adjustment, which resulted in a reduction of 2.76 percent in the CO₂ lbs/MWh. TVA’s rate is significantly lower than EPA’s current eGRID (2022) national (823.49 CO₂ lbs/MWh) and regional (933.07 CO₂ lbs/MWh) rates.
