The North American Renewable Integration Study aims to understand the value of coordinating the expansion and operation of the North American power systems. The study will conducted coordinated generation and transmission expansion planning activities for the U.S., Canada, and Mexico. Each country is providing funding to the study. After identifying a suite of scenarios using a newly developed ReEDS model of the continent, NREL and it's partners will conduct simulations of coordinated operations for the US, Canada and Mexico. The project will dramatically improve the modeling of hydro resources on the continent and provide a comparable analysis of wind in all three countries. The project is highly coordinated with 1.3.33 and 1.4.26 from the GMLC Foundational projects.
