Build with WattTime
Discover capabilities of the WattTime platform by exploring API reference documentation.
Built upon our open source project pyiso, the WattTime API offers streamlined access to power grid data including our proprietary marginal emissions data for reducing GHG's in real-time at 5-minute and hourly time granularity. Data is provided at a location-based mapping for individual power grid boundaries for marginal carbon intensities and power fuel mixes.Go to API
Explorer: Interactive Emissions Map
Emissions constantly vary by time and location. This demo showcases the emissions index of balancing authorities, illustrating the type of information AER feeds into applications.Go to Explorer
The WattTime API provides the building blocks to integrate marginal carbon emissions data into a variety of applications and provides an automated process for emissions reductions without impacting functionality. Integrating emissions data allows third-party providers and devices to make the best choices using real-time insights and forecast to plan ahead.
