Walmart Inc. reached a deal to power more than 40 stores in five states with solar energy as it works toward a goal of getting half of its electricity from renewables by 2025.

The retail giant signed 46 power-purchase agreements and leases with C2 Energy Capital LLC, the New York-based solar company said in a statement Wednesday. The projects supplying the power will produce more than 65 gigawatt-hours annually, enough to furnish as much as 60% of each store’s electricity.The stores are in Arizona, California, Louisiana, Maryland and New Jersey, Walmart spokesman Micah Ragland said in an email.
