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.

    KNOXVILLE The U.S. Senate passed the Inflation Reduction Act (IRA), an estimated $430 billion bill, of which approximately $370 billion will be allocated to investments in clean energy and to address climate change.

    It’s the single largest climate investment in U.S. history, and if it passes the House, will put the country on a path to be able to achieve roughly 40 percent emissions reduction from 2005 levels by 2030, reestablishing our influence in meeting the Paris Agreement goal of limiting global warming to 1.5 degrees Celsius. 

    If passed, the Inflation Reduction Act will:

    • Give opportunities to hundreds of thousands of Americans to work in well-paying jobs manufacturing, installing, and maintaining clean energy, energy efficiency, and clean transportation
    • Lower Americans’ cost of electricity by spurring the development of hundreds of gigawatts of low-cost clean energy, including wind, solar, and battery energy storage.
    • Protect drivers from expensive and volatile fuel costs through financial incentives to switch to electric vehicles.
    • Reduce households’ bills through historic investments in rebates and tax credits for home energy efficiency and efficient electric appliances.
    • Promote environmental justice and direct resources and benefits to disadvantaged communities, which are often overlooked for investment and bear heavy costs of fossil fuel pollution.

    Report: Many utilities are not reducing carbon emissions despite public assurances to the contrary

    KNOXVILLE Global greenhouse gas emissions must peak by 2025 and experience rapid and deep reductions to avoid a potentially catastrophic future, according to a new analysis by air-quality and climate advocates. Emissions must reach net zero by the early 2050s to limit warming to 1.5 degrees (C) in order to avoid the worst impacts of the climate crisis.

    Many utilities and municipalities have acknowledged this dynamic, but the Southern Alliance for Clean Energy’s fourth annual “Tracking Decarbonization in the Southeast" report highlights that current utility resource plans are not in line with this overarching target. Obstacles to getting utilities on track that are discussed in our report include: increasing reliance on fossil gas, underutilizing energy efficiency, and placing limitations on popular technologies such as rooftop solar. There’s still a lot of work to do before any Southeast utility is on track to decarbonize.

    When will the electrification of America’s cars, trucks, and buses really take off?

    Imminently, if not already. Look to the Southeast, which is experiencing impressive EV market growth despite a lack of state-level EV-supportive policies, incentives and regulations.

    The Southern Alliance for Clean Energy and partner, Atlas Public Policy, updated key year-end indicator data from the annual “Transportation Electrification in the Southeast” report to capture regional and state-specific growth in Alabama, Florida, Georgia, North Carolina, South Carolina, and Tennessee.

    This is a critical time for the expanding EV market. The pandemic has exposed global supply chain weaknesses related to auto manufacturing and battery production that can only be solved by increasing domestic production of critical materials and components.

  • Seal it up: Inefficiency increases energy costs across the board

    Editors note: SACE executive director Stephen Smith is on the board of Foundation for Global Sustainability. Hellbender Press operates under the FGS nonprofit umbrella.

    The Southern Alliance for Clean Energy (SACE) released its fourth annual “Energy Efficiency in the Southeast” report, which tracks recent policy developments and performance trends in electric utility efficiency from 2020.

    It continues to highlight that despite being a proven low-cost clean energy resource with enormous potential to reduce carbon emissions and customers’ energy burden, Southeastern utilities continue to underinvest in energy efficiency.

    As a result, households in many Southeastern states have some of the highest electricity usage and monthly energy bills in the nation. Some states and utilities are making progress, and it’s not too late for local policymakers to take advantage of untapped efficiency savings to help reach crucial decarbonization goals.

    For the first time in nearly two years, the publicly owned Tennessee Valley Authority will host a public listening session on the day prior to its next board of directors meeting.

    Since shifting to virtual board meetings in 2020, TVA diverged from other utilities across the country by not holding a single virtual public listening session. In addition, written comments submitted by ratepayers prior to board meetings have not been shared with the media or the public. 

  • SACE works to keep us all warm this winter

    This is a submission from the Southern Alliance for Clean Energy.

    After public advocacy from Knoxville community members, the KUB board passed a resolution that will deliver $5 million for emergency bill assistance to benefit those most in need, and an additional $1 million for weatherization to improve the comfort of people’s homes while lowering their bills by increasing energy efficiency. These funds are part of a pandemic relief credit from TVA.

    KUB staff proposed a resolution in October that would have allocated $1.3 million of the total $7.3 million TVA pandemic recovery credit toward payment of debt owed by KUB customers, and the remaining $6 million would be distributed as a monthly bill credit for all residential and small business KUB customers. This would have resulted in an average savings of $17 over 12 months, or about $1.40 per month for all KUB customers, regardless of their level of need for pandemic relief. 

    Knoxville Water and Energy for All (KWEA), a coalition which SACE is a part of, circulated a petition asking that KUB instead forgive all debt owed by KUB customers, and then use the remaining funds to assist households who were struggling to pay their KUB bills. KWEA delivered nearly 200 petition signatures, and the KUB board asked that the resolution be amended. 

    As a result of our coalition’s advocacy, the KUB board allocated not only the originally proposed $1.3 million for debt relief, but also the remaining $6 million for customers in need. 

    While KUB did not pledge to forgive all debt, this is certainly a major win for the community.

    The KUB Board’s decision to reallocate funds demonstrates the power of our community speaking up to advocate for ourselves and our neighbors.
