Amazon is turning to Tesla in order to deploy energy storage capacity at their distribution centers.

After a deal to add Tesla Powerpacks to a UK facility earlier this year, now Amazon is working with Tesla again at another distribution center. The last project included both a 4 MW solar array and 3.77 MW battery system installed at a large fulfillment center in Tilbury – east of London.

Amazon has hundreds of locations like this one around the world and at the time, it looked like if this project turned out to be successful in reducing energy costs, Amazon could decide to deploy Tesla Powerpacks at more locations, according to Eelectrek.co.

A few months later, we’ve now learned that the internet retail giant is planning a similar project at their Coalville facility in Leicestershire. Amazon reportedly plans more similar projects over the next 18 months.

Tesla Energy is aiming to ramp up its deployment of energy storage through several different channels. These deployments will range from Powerwalls at the residential level to large utility-scale projects, like the new giant project with PG&E in California, to the smaller scale commercial projects, like those with Amazon.
