NRG Energy is partnering with a virtual power plant company to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 in an overall effort to improve the Texas grid's resiliency and help households manage and lower their energy costs.

Renew Home will create a nearly 1 gigawatt AI-powered VPP, which will be enabled by Google Cloud technology and be the largest AI-enabled VPP in Texas. NRG and Renew Home expect the VPP program to arrive for Texas customers in spring of 2025.

A 1 gigawatt VPP can deliver a capacity that is equivalent to 200,000 homes during peak demand times. NRG and Renew Home plan to offer Vivint and Nest smart thermostats, which will include professional installation at no cost to eligible customers as part of the goal to build the VPP.

The advanced thermostats can make automatic HVAC adjustments that can help customers shift their energy use to times when electricity is less expensive, and cleaner. The program will combine smart devices, energy intelligence, and AI. The companies expect to add devices like batteries and electric vehicles to the VPP.

“By partnering with industry leaders like Renew Home and Google Cloud, we are set to deliver cutting-edge, AI-driven solutions that will bolster grid resilience and contribute to a more sustainable future,” Rasesh Patel, president of NRG Consumer, says in a news release. “We are excited about the transformative impact this collaboration will have on our customers and the broader energy landscape.”

NRG will also be utilizing the multi-year technology transformation with Google Cloud. NRG will be able to better predict weather conditions, forecast wind and solar generation output, and create predictive pricing models through the use of Google Cloud's data, analytics, and AI technology.

"As we move toward a more sustainable future and face increasing energy demands, Google Cloud recognizes the importance of partnering with innovators like NRG and Renew Home to help transform the consumer energy experience with AI and the best of Google Cloud,” Michael Clark, president - North America at Google Cloud, adds. "Our collaboration will help Texas meet its growing energy demands, and also empower consumers to get more from their energy, smart home, and essential home services in the future.”

Texas reached an unprecedented demand surge of 85 gigawatts in 2023.

“As rapid population growth and weather events create new challenges for meeting demand in ERCOT, VPPs can deliver a reliable, flexible and dispatchable energy resource,” Renew Home CEO Ben Brown continues. “NRG’s commitment to creating a more resilient and sustainable energy future while also making electricity bills more affordable makes them an ideal partner for co-developing this unique VPP program. This initiative raises the bar for future-proofing our electricity infrastructure and delivering cost savings to customers.”

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”
