Mars Secures 70% of Sweden's Giant Wind Farm Output

Mars, the company behind M&M's, Snickers, and dozens of other beloved brands, just signed one of its biggest renewable energy deals ever with a massive wind farm in Sweden.

The Kölvallen Wind Farm will deliver 670 gigawatt hours of clean electricity to Mars each year. That's enough power to run 95,000 homes annually, all now dedicated to helping Mars and its suppliers go green.

Mars committed to buying 70% of everything the wind farm produces through a long-term agreement. The 277.2 megawatt facility represents one of Europe's most advanced onshore wind projects and is expected to become climate neutral within just months of operation.

"Our commitment to partner with Foresight Group in this Swedish wind farm is a clear demonstration of our ambition to support the renewable energy transition across Europe," says Kevin Rabinovitch, Mars' global vice president of sustainability. The company calls it part of their Renewable Acceleration Program, which aims to make clean energy the standard across their entire value chain.

Here's what makes this deal special: Mars didn't just buy power from an existing facility. The company provided the long-term commitment Foresight Energy Infrastructure needed to actually build the wind farm in the first place, ensuring the project could move forward with construction and financing.

The Ripple Effect

This partnership creates waves far beyond Mars' factories. The wind farm generates skilled jobs and secondary employment throughout the region, providing economic stability for local communities.

A community fund supported by the wind farm's annual revenue will deliver benefits for decades to come. Meanwhile, the project sets a new benchmark for how major corporations can work with energy developers to accelerate renewable infrastructure.

Mars isn't stopping with Sweden. In 2025, the company launched more than 100 solar projects across Poland through the same Renewable Acceleration Program. With each new contract, Mars expects to reduce its total carbon footprint by 10% by 2030 compared to 2015 levels.

The Swedish wind farm shows how corporate commitments can transform entire energy landscapes, one partnership at a time.
