Nestlé Purina PetCare officially unveiled and dedicated a new solar-panel array May 14 at the company's petfood plant in Denver, Colorado, USA, according to an article from the Denver Business Journal .

The array is comprised of 467 panels and covers about 21,000 square feet on the roof of the plant.

About 100 kilowatts of power are produced by the panels - approximately 1% of the plant's electricity needs.

"It makes Nestlé Purina the first petfood manufacturer to use any kind of renewable energy directly in the production of our petfood," said Tom Plymell, operations performance manager at the plant.

If the system works well, Purina will consider putting solar systems on its dry petfood plants in Flagstaff, Arizona, USA, and Maricopa, California, USA, according to the article.
