Small Modular Reactors and Renewables: Considerations for Micro-Grid Integration at Remote Sites

Abstract

Remote communities in northern Canada are seen by those in both the Small Modular Reactor (SMR) and renewable energy communities as ideal locations for deployment. By replacing diesel generation with more cost efficient and low-carbon power generation technologies, remote sites can realize both economic and societal benefits. Though vSMRs (very Small Modular Reactors) are rapidly approaching readiness for deployment, many remote areas have also considered or are investigating renewable power generation technologies as an interim measure to address power generation issues. While SMR and renewable technologies are very different, it is possible for them to co-exist on the same micro-grid while providing both redundancy and cost effectiveness. However, challenges exist in integrating renewables with nuclear power on small micro-grids. These includes generation dispatching, addressing requirements for backup power, and proving the business case for the deployment of multiple generation technologies. A summary of the considerations for deployment of these types of power solutions is presented along with an LCOE estimate for a representative hybrid vSMR-wind-storage system.
