Hurricane Beryl’s Devastating Impact on Houston Power Grid Reinforces Value of Sunnova Solar + Storage Service for Homeowners

Sunnova Energy International, Inc. ("Sunnova") (NYSE: NOVA), an industry-leading adaptive energy services company, reinforced the value of Sunnova SunSafe® solar + battery storage service in the aftermath of Hurricane Beryl and reminded homeowners of its readiness to support their energy independence.

Natural disasters like Hurricane Beryl, which recently impacted Houston – headquarters of Sunnova – and the surrounding region, demonstrate the advantages of residential rooftop solar and battery storage over exclusive reliance on the aging power grid. Hurricane Beryl dealt a crippling blow to Houston’s power grid, disrupting power for nearly 2.7 million residents, with several thousand customers still without electricity today.

But for Sunnova SunSafe® solar + battery storage customers, the power stayed on during the storm and remained on in its aftermath, proving that in times of an emergency, a solar + storage system provides homeowners energy security and peace of mind. Sunnova’s SunSafe® solar + battery service pairs solar energy generation with battery storage, allowing customers to access solar power even when the sun is down, or the grid is out.¹

Sunnova’s solar + storage systems experienced uninterrupted power throughout the storm protecting the homes of Houston-area customers and employees – including Sunnova CEO William J. (John) Berger, who gave a live interview with CNBC in the middle of the hurricane.

“Future disasters like Hurricane Beryl aren’t an ‘if,’ but a ‘when,’” said Berger. “While it was Houston’s grid this time, grid failure happens all over – from hurricanes in Puerto Rico and Florida to wildfires in California and Hawaii. Sunnova has a proud history of serving customers through these disasters and providing resilient solar and battery storage services across 51 US states and territories.”

Sunnova’s residential solar + storage systems are backed by the industry-leading, 25-year Sunnova Protect™ service guarantee, 24-hour remote system monitoring, and the continuous support of its dedicated customer care call centers and field service technicians. Having grown more than 230% since 2020, the company’s service teams provide rapid response times for Sunnova customers to help ensure the power keeps flowing. Additionally, Sunnova’s state-of-the-art Global Command Center in Houston is equipped with cutting-edge technologies, analytics, and tailored solutions to enhance the customer experience.

“Sunnova stands ready and able to partner with customers to help power their energy independence with our battle-tested solar + storage systems,” said Michael Grasso, Executive Vice President and Chief Revenue Officer at Sunnova. “While overburdened, aging US power grids are showing their strain, our residential solar offerings provide the power to live life uninterrupted®.”
