A power centre is an unenclose shopping centre with 250,000 square feet (23,000 m²) to 600,000 square feet (56,000 m²) of gross leasable area that usually contains three or more big box retailers and various smaller retailers (usually located in strip malls) with a common parking area shared among the retailers. It is likely to have more money spent on features and architecture than a traditional big box shopping center.
