Tennessee Valley Authority (TVA) Case Study: Customer Solutions Supplier-Specific Emission Rates

The Tennessee Valley Authority (TVA) provides as-delivered CO2 emissions rates to directly-served customers since 2012 and local power company (LPC) customers with demand over 5 MW since 2017. Unlike standard annual consumption rates, TVA uses hourly electric consumption profiles compared to the annual hourly TVA system CO2 emission rate to determine supplier-specific figures for market-based Scope 2 reporting. To support these customers, TVA developed a spreadsheet tool that allows users to compare the cost and Renewable Energy Certificate (REC) consumption differences between renewable energy goals and clean energy goals, with options to customize generation sources such as biomass and nuclear.

• TVA calculates as-delivered CO2 emissions rates for directly-served customers starting in 2012, and for local power company (LPC) customers with a demand exceeding 5 MW starting in 2017.
• TVA's supplier-specific CO2 lbs./MWh rates for large customers are derived from hourly electric consumption profiles compared against the annual hourly TVA system CO2 emission rate, rather than based on annual electricity consumption.
• TVA developed a spreadsheet tool that enables customers to input energy price and consumption data to analyze the cost and REC consumption differences between pursuing a percentage renewable goal versus a percentage clean energy goal.
• The customer tool allows for the customization of generation sources to be counted, specifically mentioning biomass and nuclear, and enables the comparison of predicted 2030 CO2 reduction targets against base years.
