Tennessee Valley Authority will build on its carbon reduction by aspiring to move toward net-zero carbon emissions by 2050 based on a set of guiding principles endorsed by the TVA Board of Directors at its recent quarterly business meeting.
As outlined in TVA’s most recent Sustainability Report, TVA’s continuing execution of its nearly 88 year-old mission – supplying reliable energy at the lowest feasible cost, being a steward of the region’s natural resources, and serving as a catalyst for continued economic development – must be viewed through the lens of future sustainability.
Businesses and industries are already seeing the unique value of that approach. In the first six months of fiscal year 2021, TVA helped attract or retain more than 45,200 jobs and $3.9 billion in investment to the region, not including recent significant news from LG, Milwaukee Tools, and Oracle.
Since 2005, TVA has reduced carbon emissions by 63% primarily through creating one of the most diverse generation portfolios in the nation. This includes adding 1,600 megawatts of new nuclear capacity – the most of any utility in the nation; an additional 1,600 megawatts of wind and solar capacity; retiring 8,600 megawatts of coal capacity that was at the end of its useful life by the end of 2023 and investing more than $400 million to promote energy efficiency.
“The steps we’ve already taken operationally and financially have created a strong foundation for supplying cleaner energy without impacting reliability or low cost,” said Jeff Lyash, TVA president and CEO. “TVA is an industry leader in carbon reduction, but we aren’t satisfied. We are focused on increasing carbon reduction while maintaining our commitment to the low-cost, reliable energy our customers expect and deserve.”
The Board approved a resolution endorsing TVA’s Strategic Intent and Guiding Principles, which outlines the TVA leadership team’s intent to align its people, operational, and innovation efforts to business strategies that provide reliable, resilient, low-cost, and clean energy to the region.
The document establishes a series of decarbonization milestones over the next three decades. By 2030, TVA would focus on growing its current 63% carbon reduction to 70% by doing the following:
•Continuing to expand renewable generation, including 2,300 megawatts that is already committed and will be online by 2023.
•Expanding battery storage capacity as technology develops and costs decline.
•Further reducing coal generation as plants reach the end of their service lives – TVA’s current planning assumptions indicate the retirement of all coal units by 2035.
•Leveraging natural gas generating facilities as a bridging strategy to effectively allow the addition of more renewable energy without impacting system reliability.
Specific plans to achieve this milestone, including any decisions affecting existing or new facilities, will be developed over the coming months and will include detailed environmental assessments that will seek public input before any actions are taken.
TVA has a path to an 80% reduction by 2035 with up to 10,000 megawatts of solar capacity online and continued investment in extending the lives of current nuclear and hydro fleets, as well as the integrated systems necessary to support the energy system of the future, while moving toward its aspirational goal of net-zero carbon emissions by 2050.
“We are confident we can approach an 80% reduction by 2035 using existing technology and without impacting TVA’s reliability or costs,” said Lyash. “Moving to net-zero carbon emissions will require public and private partnerships to further evolve existing technologies, such as energy storage systems and carbon capture, and develop new capabilities, such as advanced nuclear solutions. TVA stands ready to lead in these innovation efforts.”
Leveraging its extensive experience in nuclear power operations, TVA is partnering with Kairos Power to assist with the deployment of a Hermes low-power demonstration reactor in East Tennessee Technology Park in Oak Ridge.
In addition, TVA continues to explore the potential of light-water-based small modular reactors at the Clinch River Site, which holds the nation’s only NRC early site permit for small-modular reactor development.
“Our Sustainability report recognizes that power generation is only one part of the overarching challenge of decarbonizing our economy and TVA remains actively engaged in supporting the electrification of transportation and other initiatives to help achieve that goal,” said Lyash. “Our current partnerships with state and utility partners to expand electric vehicle charging infrastructure in our region is one example of how TVA is leading this effort.”
Wholesale rates remain lower than 10 years ago.
TVA Chief Financial Officer John Thomas said, “Our employees’ hard work driving efficiencies into our business and improving our balance sheet over the past eight years means that executing our decarbonization goals will not impact our intent to maintain stable rates through at least 2030.”
Over the first six months of TVA’s fiscal year, total operating revenues decreased 4% over the same period in the previous year, primarily due to lower base rates and lower fuel costs, both of which supported lower costs for customers. Interest expenses were 3% lower than last year due to lower debt levels. During the same period, the TVA team also did the following:
•Provided $104 million in Pandemic Relief Credits to all 153 local power companies, their large commercial and industrial customers, and TVA directly served customers in the first six months of fiscal year 2021.
•Generated 60% of TVA’s energy from carbon-free sources.
•Continued to manage wetter-than-normal conditions throughout the Tennessee River system.
Tennessee Valley Authority is a corporate agency of the United States that provides electricity for business customers and local power distributors serving nearly 10 million people in parts of seven southeastern states. TVA receives no taxpayer funding, deriving virtually all of its revenues from sales of electricity. In addition to operating and investing its revenues in its electric system, TVA provides flood control, navigation, and land management for the Tennessee River system and assists local power companies and state and local governments with economic development and job creation.
