Microsoft is committed to reducing our environmental footprint, and over the past two years we continue to meet our goal of becoming carbon neutral. Our approach to meeting that goal, however, continues to evolve. Today, we are announcing another move to make our operations more environmentally sustainable by signing a 20-year power purchase agreement (PPA) for wind energy in Illinois that will be funded in part by proceeds from Microsoft’s carbon fee.

This is our second PPA, following the purchase in November of wind energy from the Keechi Wind Project in Texas. This most recent power purchase, the Pilot Hill Wind Project, is our largest wind investment to date. It is nearly 60 percent larger than Keechi, at 175 MW versus Keechi’s 110 MW. This project builds on our commitment to renewable energy and our strategic objective to transform the energy supply chain toward radically greater efficiency and reduced environmental impact.
