On Friday, Walmart announced that is has concluded a request for proposals and has accepted bids from SunEdison and SolarCity to install as many as 400 new solar PV systems on its facilities over the next four years.
The company did not say what capacity this will represent, but estimates that the PV systems will meet 10-30% of the energy needs of the facilities where they will be installed.
If 400 are built and they average the same size as Walmart’s existing fleet of PV, the new installations will total around 160 MW. Walmart currently has 260 operational PV plants at its stores, representing 105 MW of installed PV capacity.
This makes Walmart, the world’s largest retailer, also the largest corporate user of PV in the United States. The company boasts more than double the installed PV versus its closest competitor.
