Thousands of Texas homes are about to form a huge virtual power plant

Abundance Energy, sonnen, and Energywell are teaming up to bring smarter, more resilient energy to Texas homes through a huge new virtual power plant (VPP) initiative.

By combining behind-the-meter home batteries, solar power, and advanced energy software, the trio is building a network of connected homes that can work together to support the grid. Customers who install sonnenConnect home batteries through Abundance Energy will now be part of a system that automatically stores and shares power when it’s needed most. That means lower electricity bills, better reliability during extreme weather, and a cleaner energy mix overall.

The VPP will cover all of ERCOT, with the primary focus in the greater Dallas-Fort Worth and Houston areas. Each home will have two 4.8kW/20kWh sonnenCore+20 battery units. The current customer base that will be enrolled in the VPP equals 60 MWh, and this will continue to grow each month. The VPP is already on track to replace Tesla as the largest virtual power plant in Texas by the end of 2026.

Here’s how it works: The batteries are continuously managed using Energywell’s Proton platform and sonnen’s smart VPP technology. This system monitors solar generation, customer energy use, and real-time electricity prices, and then decides when to charge or discharge each battery. Instead of just sitting idle, these batteries turn into mini power plants that can react to grid needs in real time.

And when thousands of batteries work together, they form a virtual power plant—a decentralized network that reduces the strain on the grid, especially during peak demand or power outages. Unlike traditional power plants, VPPs don’t burn fossil fuels. They use clean, stored electricity from homes and businesses, helping cut carbon emissions while keeping the lights on.

“Our mission is to empower homeowners with smarter, more sustainable energy solutions,” said Thomas Mandry, CEO of Abundance Energy. “This partnership delivers a new kind of VPP model that benefits customers and strengthens the Texas grid.”

Blake Richetta, CEO of sonnen, added, “With Abundance Energy and Energywell, we’re showing how everyday homeowners can become part of the solution to Texas’ energy challenges.”

As Texas continues to face grid reliability issues, especially in extreme heat or cold, this kind of flexible, customer-powered energy system will make homes more resilient and give customers more control over their power.
