As Hellbender Press reported in April, the Tennessee Valley Authority plans to phase out its use of coal. And as we mentioned in an action alert, TVA is conducting a scoping process pertaining to the preparation of an Environmental Impact Statement (EIS) for retirement and replacement of the Kingston Fossil Plant. TVA is preparing similar EIS for its other remaining coal-fired power plants as well.

Although TVA lists "construction and operation of solar and storage facilities" in these scoping documents as an alternative for replacement of coal as the power source, it has made no secret of its belief that construction of gas-powered combustion turbines (CT) and natural gas pipelines to feed them will be the best solution to replace the outdated generation capacity.

Unlike other power utilities, TVA has been making it more difficult, financially unattractive or impossible for distributed renewable energy, storage and even efficiency projects to get realized, according to proponents of renewables and some of TVA’s local power distribution partners. TVA also reneged on its agreement with other utilities to make large amounts of wind power available to the Southeastern United States through the Plains & Eastern Clean Line high-voltage direct-current power line project.

Below, we reprint the statement submitted by FGS during the public comment period for the Kingston Fossil Plan Retirement.

The Foundation for Global Sustainability urges TVA to truly step up to the challenges of climate change

The action alternatives in the dockets for the replacement of TVA’s coal fired power plants are shortsighted and most disappointing.

As a quasi-federal entity with a de-facto monopoly over a vast area of our nation, the Tennessee Valley Authority should strive to spearhead, exemplify, and not only meet — but exceed — most of the federal goals for decarbonization.

By basing plans primarily on data of historic trends — unquestioningly projected into the future — TVA is apt to commit yet another horrendous miscalculation; it is prone to saddle itself with even more stranded assets.

Addressing the climate change crisis

Rarely a month passes without scientific discoveries of natural feedback mechanisms that aggravate the consequences of climate change. Signs that Earth’s natural life-support systems are approaching tipping points are multiplying.

At the same time that uncertainty about prevailing conditions over the lifetime of infrastructure investments is growing, technologies are evolving at an increasing pace. Many private-sector corporations have already realized that time-proven business practices are no survival strategy.

What’s called for today is more nimble management. TVA needs to focus on cooperative, adaptive planning for more flexible, responsive operations.

A multitude of smaller investments that seek to attack problems from a diversity of facets will have greater probability of success than monolithic huge investments that are hard to revert, abandon, or repurpose.

We encourage TVA to take a step back, to first look at what it can do to help improve the sustainability and resilience of our regional and local economies and of its large, small, and individual customers, WITHOUT investments that lock in carbon emissions for decades.

Although we welcomed, appreciated, and supported TVA initiatives such as Energy Right, Green Power Switch and Generation Partners, one has to admit that in the larger context they amounted to little more than public relations Band-aids.

Distributed renewable energy generation and storage

It is high time for TVA to stop stonewalling renewable energies.

The promising potential of widely distributed renewable energy generation and storage to minimize transmission losses and to boost community resilience is still largely untapped. It lends itself to easily manageable, quick turn-around, incremental projects that can readily be evolved and fine-tuned as new conditions, greater insights, and better technologies emerge.

People in TVA’s service areas are no less likely to welcome and personally invest in solar energy and storage than the people of Germany have done, despite getting far less sunlight in their northern latitudes than we enjoy here; if only TVA relaxes its severe restrictions and abandons its adversarial stance.

We call upon TVA to embrace, as major planning objectives, environmental sustainability and efficiency from energy generation all the way through end use.

Sincerely,

Southern Alliance for Clean Energy offers detailed climate action items for fossil-based utilities

A new SACE report shows not only that is it possible for the four largest utilities in the Southeast to achieve 100 percent clean electricity, but there are several pathways to get there. A variety of different energy technologies and programs can be deployed to reach this goal.

The key takeaway is that we need to start now.

clean electricity standard is a policy that requires utilities to use clean energy resources to generate a minimum portion of all energy by a certain date. Since the first renewable standard was passed in Iowa in 1983 states and utilities across the U.S. have a lot of experience with this kind of policy.

As part of federal climate action, the Biden administration and several members of Congress have proposed different versions of a Clean Electricity Standard (CES) that achieves 100 percent clean electricity by 2035. SACE has called for the Tennessee Valley Authority (TVA) to lead the way by getting to 100 percent clean electricity by 2030.

To help us understand what 100 percent clean electricity would look like here in the Southeast, SACE staff developed pathways to meet a CES policy for our region’s four largest utility companies: TVA, Southern Company, NextEra (which owns Florida Power & Light and Gulf Power), and Duke Energy.

On Wednesday, June 16, and Thursday, June 17, SACE’s policy staff will host webinars focusing on pathways to 100 percent clean electricity for each of the utilities examined in the report: Duke Energy, NextEra, TVA, and Southern Company, including:

-What a federal Clean Electricity Standard is and how it could be key to kickstarting aggressive decarbonization;

-Multiple pathways with a different power generation mix for each utility to reach net-zero carbon emissions; 

-How distributed resources like rooftop solar and energy efficiency are key to decarbonizing; and

-Descriptions of the method used to develop and test each pathway to clean electricity.

Register for one or more of the following webinars Wednesday, June 16, and Thursday, June 17:

Download the report: “Achieving 100% Clean Electricity in the Southeast: Enacting a Federal Clean Electricity Standard.”

The primary pathway is focused on distributed energy resources (DERs). We found that with significant and sustained investments in DERs, like energy efficiency and rooftop solar, these utilities can achieve a customer-oriented pathway to clean electricity. In fact, these two resources, energy efficiency and rooftop solar, could meet approximately one-third of all electricity needs for these utilities by 2035. In addition to these distributed resources, these successful pathways will also include wind power, large-scale solar, and energy storage.

We found that when utilities have the ability to share resources to meet peak needs and reserve margins, fewer resources are needed overall. In most parts of the country, utilities already have the ability to do this through competitive electricity markets, but not in the Southeast. Having one such market that spans across the Southeast would help the region as a whole achieve 100 percent clean electricity.

Our analysis only looked at existing technologies. While it is good to know that today’s technologies can play a critical role in the pathway to 100 percent clean electricity, and so we must ramp up these technologies immediately, it is also true that investments in technology innovation are important to make it easier to get there. We still need to invest in research and development that can lead to improvements of existing clean electricity technologies and commercialization of new clean electricity technologies. This should not be a question of either deployment or research, both are needed.
