TVA Files First U.S. Small Modular Reactor Construction Permit

In a historic move, the Tennessee Valley Authority (TVA) became the first utility in the U.S. to file a Construction Permit Application (CPA) for a Small Modular Reactor (SMR) with the Nuclear Regulatory Commission (NRC).

Highlights

• Capacity: 300 MW
• Location: Clinch River site, Tennessee
• Target Completion: By 2032
• Federal Funding: TVA is leading a consortium seeking an $800 million DOE grant to support project development.

Consortium Partners include Bechtel, Duke Energy, BWX Technologies, Indiana Michigan Power, EPRI, Oak Ridge Associated Universities, and others.

This development reinforces nuclear’s critical role in future grid reliability, particularly as SMRs offer smaller footprints, scalability, and enhanced safety features. It also indicates federal alignment on advanced nuclear as a key pillar of long-term energy security.

NRG Expands Capacity with Major Natural Gas and VPP Acquisition

In a significant expansion of its generation portfolio, NRG has announced the acquisition of 18 natural gas-fired facilities from LS Power, totaling approximately 13 GW across nine states. The move strengthens NRG’s generation footprint in core markets like Texas and the Northeast, which are both areas with rapidly growing energy demand.

The deal also includes a Commercial & Industrial Virtual Power Plant (C&I VPP) platform, known as C Power, which boasts 6 GW of flexible capacity and serves more than 2,000 C&I customers in all major deregulated markets.

With this acquisition, NRG is positioning itself to offer tailored, long-term energy solutions to large users, particularly data centers and industrial clients seeking flexible supply and grid participation options.

Tech Giants Double Down on Carbon-Free Power

In a series of high-profile announcements, major tech companies have committed to sourcing nuclear and geothermal power to meet the energy demands of AI and cloud infrastructure.

Amazon + Talen Energy

Amazon signed a Power Purchase Agreement (PPA) with Talen Energy for 1,920 MW of nuclear energy to run data centers in Pennsylvania through 2042. The power will be delivered from Talen’s Susquehanna nuclear facility, with full volume expected by 2032.

This is one of the largest nuclear PPAs ever signed by a private company and reflects growing interest in firm, carbon-free power to support energy-intensive computing operations.

Meta + Constellation + XGS Energy

Meta entered a 20-year PPA with Constellation Energy for 1,121 MW of nuclear energy from the Clinton Clean Energy Center in Illinois starting June 2027. The deal also supports the plant’s relicensing when Illinois’ zero-emissions tax credit expires in 2027.

In addition, Meta signed a deal with XGS Energy to procure 150 MW of geothermal energy for its New Mexico data center. This follows a previous geothermal agreement with Sage Geosystems, marking Meta’s increasing diversification into firm renewable technologies.

Why This Matters

These long-term carbon-free power deals underscore the accelerating shift toward 24/7 clean energy. For energy suppliers, this trend opens the door for:

• Creative contracting and hedging strategies
• New product development focused on firm renewables
• Strategic partnerships with nuclear, geothermal, and other non-intermittent energy providers

ERCOT Expands Demand Response and Emergency Generation in Texas

As Texas continues to face grid strain during periods of extreme heat, ERCOT is working with stakeholders to expand residential demand response capabilities through smart technologies. Retail Electric Providers (REPs) will be central to the rollout, offering customers incentives for using smart thermostats, appliances, and energy management systems that can automatically adjust consumption during peak times.

Meanwhile, ERCOT, CenterPoint, and other partners are deploying 15 large temporary diesel generation units—each with 30 MW capacity—to bolster reliability in the Greater San Antonio area. These units are designed for rapid deployment (full output within 10 minutes), operate 24/7, and will be in service for up to two years to mitigate the risk of shortfalls.

Together, these efforts represent a two-pronged approach: reducing peak demand with smart devices while reinforcing supply with flexible generation capacity.

Senate Energy Bill Proposes Tax Credit Phaseouts for Wind and Solar

On June 16, the U.S. Senate Committee on Finance released draft language for the "One Big Beautiful Bill," a wide-ranging energy and tax reform proposal.

• Projects starting in 2025 qualify for 100% of the Investment (48E) and Production (45Y) Tax Credits
• Projects starting in 2026 qualify for 60%
• Projects starting in 2027 qualify for 20%
• Projects starting after 2027 will receive 0%

In addition, the bill introduces a new tax on wind and solar projects placed into service after 2027 if they include a significant percentage of components from foreign entities of concern (FEOCs), such as China. Notably, this tax would apply even if the project does not claim any tax credits. The move is intended to boost domestic manufacturing and reduce dependency on foreign-sourced materials.

For renewable developers and energy suppliers, these changes raise the stakes for project timelines and sourcing decisions, making forward planning and flexible procurement strategies more critical than ever.

Senate Bill 6 Brings New Rules for Texas Data Centers and Large Loads

Another piece of legislation that is shaping the energy market includes Texas Senate Bill 6, recently signed into law, which introduces a dual-path demand management framework to improve grid reliability among high-volume power users like data centers.

• A mandatory program applies to loads of 75 MW or more connecting to ERCOT after January 2025. Participants must install shutoff equipment and allow utilities to curtail their load during firm load shed events.
  
  
• A voluntary program offers competitive compensation for grid support during designated periods but requires a 24-hour advance notice and prohibits participation from loads already involved in other curtailment or pricing-based programs.

For suppliers and large-load customers alike, this legislation provides greater regulatory clarity and a new model for how hyperscale data centers and industrial operations can play an active role in grid reliability.

What Energy Suppliers Should Watch

The energy landscape is being reshaped by both market forces and federal policy. For energy suppliers, these developments point to several actionable takeaways:

• Voluntary REC markets are growing in importance, especially for commercial and institutional buyers aiming to showcase environmental leadership.
• Firm carbon-free energy is in high demand, and suppliers should explore nuclear and geothermal partnerships to stay competitive.
• Federal policy remains fluid, with potential tax credit changes on the horizon. Flexibility in compliance planning and resource procurement will be crucial.

As we head into the second half of 2025, energy suppliers who stay informed and agile will be best positioned to capitalize on emerging opportunities.
