Wind, photovoltaic (PV), and energy storage system (ES) technologies have observed significant cost reductions as they have continued to mature and reach mass production 1, 2, 3. The electric grid is evolving from an electrical network composed primarily of large centralized fossil fuel plants to a more distributed infrastructure, which includes renewable and energy storage type plants. This demonstration showcases the feasibility of using QKD to improve the security of critical infrastructure, including future distributed energy resources (DERs), such as energy storage.

The developed method was prototyped in a software package to manage and utilize cryptographic keys to authenticate machine-to-machine communications used for supervisory control and data acquisition (SCADA). In particular, we make such demonstration on a deployed electric utility fiber network. Here we report the first use of quantum key distribution (QKD) keys in the authentication of smart grid communications. However, leveraging modern communications systems also makes the grid vulnerable to cyberattacks.
Information technology is intended to improve the future electric grid’s reliability, efficiency, and sustainability by implementing advanced monitoring and control systems. Smart grid solutions enable utilities and customers to better monitor and control energy use via information and communications technology.
