Methodology for Time-Shifted Electricity Consumption Targeting Less Carbon-Intensive Generation

There are billions of devices worldwide that consume energy from electricity grids. Most devices, from air conditioners to electric cars, have some flexibility in exactly when they must consume electricity. Despite this flexibility, devices consume electricity regardless of the frequently-changing carbon intensity of their electricity grid. In an effort to reduce emissions, WattTime, a non-profit subsidiary of the Rocky Mountain Institute, has developed an innovative “Internet of Things” technology and accompanying methodology that assesses the carbon intensity of an electricity grid in real-time in order to identify periods for connected devices to use less carbon-intensive electricity by initiating their energy consumption earlier or later than intended. The methodology applies to project activities using a carbon advisory service to shift the electricity usage of devices from times of high carbon intensity to periods of lower carbon intensity. The methodology uses an activity method for the demonstration of additionality, which will help streamline the project development and assessment process.


The full draft of the Methodology for Time-Shifted Electricity Consumption Targeting Less Carbon-Intensive Generation is available on our website for you to review. Please send any comments to by 25 May 2018.
