Enel Green Power North America has signed a 100MW virtual power purchase agreement (VPPA) with Kellogg Company.

Under the deal, the Enel subsidiary will sell a total of 360GWh of renewably-generated energy to the US food manufacturer. This will be delivered to the grid annually from the Azure Sky wind and storage project.

The VPPA covers the equivalent of 50% of the electricity volume used across Kellogg’s manufacturing facilities in North America. This is equivalent to powering 43,000 homes each year in North America, and is estimated to avoid more than 250,000mt of carbon emissions annually.

The agreement will bring the Kellogg Company halfway to meeting its global goal of reducing its Scope 1 and 2 greenhouse gas emissions by 65%.

Kellogg Company chief sustainability officer Amy Senter said: “Kellogg has been working to reduce its carbon footprint across our value chain for more than a decade.

“This latest VPPA further demonstrates to investors, stakeholders and our consumers that we are taking swift action to address climate change.”

Enel has begun construction works of the Azure Sky wind project, the company’s first large-scale hybrid project globally to integrate wind and battery storage at one site.

Located in Throckmorton County, Texas, the 350MW wind farm has nearly 137MW of battery storage facility. The facility will use 79 turbines, generating more than 1,300GWh annually.

The battery storage system at the site will store power generated by the wind turbines, while also providing services to enhance grid flexibility. The Azure Sky project is expected to offset 842,000t of carbon emissions each year.

Enel Green Power CEO and Enel Global Power Generation head Salvatore Bernabei said: “As our first large-scale project to pair wind and storage, and our largest hybrid plant globally, Azure Sky demonstrates Enel’s continued commitment to leading the energy transition towards a 100% renewable powered electric grid.

“This transition is supported and accelerated by commercial customers, like Kellogg Company, who are placing sustainability at the core of their business.”
