Retailer Macy’s Adds 21 Rooftop Solar Arrays, Three with Storage

On April 21, nationwide retailer Macy’s announced that 21 high-efficiency SunPower solar arrays have gone live this year at its Macy’s and Bloomingdale’s locations in seven states, totaling 15 MW – and adding to the nearly 24 MW of SunPower solar that has been operating on its store and fulfillment center rooftops since 2007. Electricity generated by the new solar power systems ultimately will be sold to others.

About 70 percent of the 102 solar power systems in the Macy’s and Bloomingdale’s renewable energy portfolio feature SunPower’s high-efficiency technology. Nineteen of the 21 new systems use the SunPower Helix Roof product, a fully-integrated rooftop solar solution for commercial customers.

In addition to solar systems, Silicon Valley-based SunPower provided Macy’s with battery storage systems at three stores in Southern California. The energy storage technology is expected to help those locations further manage energy costs by offsetting demand charges incurred by commercial customers.

Macy’s financed the majority of the SunPower solar systems on its stores through power purchase agreements, allowing it to buy power at competitive rates that act as a hedge against future utility rate increases with no upfront capital cost. Macy’s does not own the renewable energy credits associated with most of the SunPower solar energy systems installed on its facilities.

“As a leading national retailer with 140,000 dedicated associates, we have the opportunity to make a meaningful difference in improving the environment,” said Chuck Abt, SVP of Operations for Macy’s. “Working with SunPower, we have been able to maximize the value of unused roof areas at our stores and fulfillment centers across the country.”

In 2016, Macy’s ranked fourth among corporations nationwide for installed solar according to the Solar Energy Industries Association.
