We believe through our commitment to 100% renewable energy we can change Wireless for Good. Our strategy combines clean energy, network resiliency and bold inspiration to create both a thriving business and a sustainable world.
Our key energy metrics, energy and carbon intensity both saw strong improvements in 2018:
These improvements largely resulted from a 34% increase in data traffic while only experiencing a 13% increase in energy usage. Efficiencies in our equipment allowed for greater traffic loads without requiring an equal increase in energy consumption.
Our Renewable Energy Commitment: In 2017, T-Mobile announced an industry leading commitment to achieve 100% renewable energy usage by 2021. We view tackling climate change and leading on renewable energy as a tremendous opportunity for T-Mobile to challenge the status quo and seize both financial opportunity and the mantle of industry leadership.
Since our last update we have grown our renewable energy portfolio and added over 160 MW through our Solomon Forks Wind Project in Kansas, which will be operational as of July 2019. With this project we will produce an estimated 625 GWh of electricity annually. This doubles the capacity we put online through our pioneering Red Dirt wind project in Oklahoma.
The combined production of the Red Dirt Wind Power and the Solomon Forks Wind Project is a total contracted capacity of 320 MW. These 12 and 15-year clean energy contracts will reduce T-Mobile’s operating CO2 emissions across our US retail stores, call centers, and network operations.
We have also taken an important step to ensure our corporate headquarters in Bellevue, Washington is powered by renewable energy, by joining Puget Sound Energy's "Green Direct" program which provides renewable energy directly through the local utility.
Energy Efficiency Projects: Our energy team researches and designs innovative ways to boost efficiency and cut energy across our entire business. Here are some ways we are optimizing the operation of our network:
