A groundbreaking new Virtual Power Plant Power Purchase Agreement (VPA) provides Texans with solar panels and two 20 kWh sonnen batteries at no upfront cost.
A new sonnen storage + solar VPP for Texans
SOLRITE Energy, which finances solar and battery storage, and global battery storage manufacturer sonnen today announced the launch of their new VPA in Texas’s ERCOT market. This program offers solar and battery storage for homeowners at an affordable monthly rate, making backup power accessible for many Texans.
Here’s how it works: SOLRITE installs solar panels and sonnen batteries at eligible customer households with no upfront cost. (I’ve asked the sonnen spokesperson what the eligibility criteria are and will update this post when I hear back.) Homeowners then pay a lower-than-average rate for the solar energy they produce each month, saving them money compared to typical electricity rates in Texas.
Texans participating in the SOLRITE program pay a leading rate of 12¢ per kWh for solar energy, significantly lower than the 19-20¢ per kWh rate commonly seen in the state.
The sonnen batteries provide backup power for each home at no charge and enable Texan homeowners to join a larger virtual power plant (VPP) network. The VPP supports the Texas grid, reducing reliance on polluting power plants during times of high demand. SOLRITE and sonnen generate revenue from the energy stored in these batteries, which helps cover the cost of the equipment, and that’s what allows homeowners to use the battery systems at no cost.
Each day, the sonnen batteries in the VPP help balance the Texas grid by directing power where it’s needed most and when it’s most valuable. This reduces energy costs for everyone, whether they’re in the VPP or not, and strengthens the grid’s efficiency and resilience.
The VPP also differs from traditional solar buyback programs that send extra energy to the grid whenever it’s sunny. Instead, the sonnen battery network strategically controls when and how energy is shared with the ERCOT grid, making solar energy a more reliable power source.
Since September 2024, SOLRITE says it’s already committed over 40 megawatt-hours of residential battery power to the Texas market through this program, working with solar installers statewide.
Blake Richetta, chairman and CEO of sonnen Inc. USA said:
The bold and inventive SOLRITE introduction in the Texas market represents the most successful early-stage launch of the sonnenConnect VPP in the world.
sonnen is proud to dispatch authentic VPPs across the United States and Australia, as well as the largest behind-the-meter residential battery based VPP in the European Union – with nerve centers in Germany, Italy and Belgium, amongst other countries.
And in all of these markets, we have never seen anything like the SOLRITE Texas launch. We are so proud of the SOLRITE invention, and we are passionate to build a SOLRITE-Future for Texas.
Electrek’s Take
I belong to a virtual power plant in Vermont and have two Tesla Powerwalls, and I love being part of this program. I lease my Powerwalls for $55 a month and had to pay a couple thousand dollars to have them installed, so what sonnen and SOLRITE are offering to Texans is a really good deal.
