Mission

WattTime is a registered California 501(c)3 nonprofit organization.

Our mission is to raise awareness about the potential to reduce environmental harm by shifting electricity use to particular times, and to encourage the development and spread of common protocols for this practice.

Here’s what we’ve done so far:

  • Developed the first real-time marginal grid analysis algorithms
    To shift electricity use to cleaner times, first you have to decide which times are cleaner. So in January 2014, we developed the first comprehensive grid analysis technique to identify the environmental impacts of using energy at any particular place and time for any point in the continental United States in real time. Our method builds on the marginal causal analytical techniques in the published literature. But those papers produced estimates years after the fact while our technique works in real time, something that has never been done before.
  • Developed the first real-time marginal carbon API
    Not content just to push the envelope in environmental research, in May 2014 we released our analysis online by constructing a real-time data service to provide this information to software developers anywhere through a simple web application programming interface (API). Since then we have constructed a number of simple tools for anyone to see their marginal carbon footprint in real time, such as this real-time map.
  • Documented consumer interest in environmental demand response
    Through a variety of field surveys and simple demonstration apps such as our text message-based messaging system, we demonstrated the interest of electricity customers have in reducing their carbon footprints through intelligent timing. We’ve also supported other software developers in using our data to write apps for this purpose, like Eric Paulos of the UC Berkeley Center for New Media.
  • Conducted the first ever automated environmental demand response demonstration project
    In February 2015, we launched a project at University of California, Merced, to automatically cause a collection of Merced’s electric vehicles to charge at the cleanest time of the night. Using Schneider Electric brand smart plugs connected to our API, we demonstrated the potential for an organization to use intelligent timing to achieve its ambitious sustainability goals at low cost.
  • Empowering others to use our technology
    We envision a world where “environmental demand response” is available to anyone who wants it. That’s why we support hardware manufacturers in developing means to provide automated environmental demand response to users in a growing variety of fields. On June 25, 2015, our partner Electric MotorWerks released the world’s first electric vehicle charging station that can automatically lower the carbon footprints of electric vehicles, offering the first solution to a classic environmental critique of grid-connected electric cars. Next, our partner Building Clouds began deploying the technology on large commercial HVAC equipment including RTUs and air handlers. Now, our partner Energate is piloting the same technology in smart thermostats.
