Under the new agreement, Base’s home energy offerings available to Walmart customers and Sam’s Club members. Customers and members who enroll in an eligible Base Power home battery offering at participating Walmart and Sam’s Club locations will receive a 20% discount on the company’s standard upfront battery installation fee, beginning in November 2026.

The companies said that the offering will initially launch in Texas, Base Power’s largest market, with plans to expand to additional locations and markets over time.

Base Power gives them a practical way to help lower energy costs, have backup power during outages and support a more reliable grid. We’re proud to make these solutions more accessible through Walmart and Sam’s Club.”
