Salesforce Signs Contract with Texas Wind Farm by Heather Clancy @FortuneMagazine January 14, 2016, 10:33 AM EST E-mail Tweet Facebook Linkedin Share icons UPDATE: This story was updated Jan. 14 to clarify the relationship of these agreements to Salesforce’s current power consumption. Mere weeks after disclosing its first big clean energy contract, cloud software giant Salesforce is talking up another deal. This one is with a wind farm being built in Texas, slated to start generating electricity in December. Under the 12-year purchase agreement with developer EDF Renewable Energy, Salesforce crm will buy approximately 102,000 megawatt-hours of power annually, or 24 megawatts of the farm’s anticipated capacity. Its first deal of this nature, announced last month, is larger. That arrangement covers about 125,000 megawatt-hours sourced from a facility owned by Enbridge enb in West Virginia. Considered together, the contracts cover more electricity than Salesforce used last year, according to CFO Mark Hawkins. He’s planning for the future. “I look for things that make economic sense and that give me predictiveness,” Hawkins said. SIGN UP: Get Data Sheet, Fortune’s daily newsletter about the business of technology. Salesforce, like many other technology companies, has committed to powering the entirety of its operations with electricity generated by renewable sources such as solar or wind farms—at some unspecified future date. Complicating this goal is the fact that Salesforce leases its data centers, which means it is more difficult to buy clean power directly. Both of these recent sourcing contracts are known as “virtual power purchase agreements.” The power isn’t actually being fed into Salesforce’s facilities directly; rather, it’s being added to the nearby electric grid.

Find out in this Fortune video: Hawkins hinted that additional agreements are in the offing. “You should expect more,” he said. Although it might seem counterintuitive, the state of Texas is the largest generator of wind energy in the United States. About 10% of its power comes from this source. Last July, Facebook fb disclosed plans to build a $1 billion wind-powered data center there. Construction should be complete by the summer.
