Jetstream is a data system to connect remote assets and PJM to satisfy real-time, market and other data transactions. Small generators, load response assets and other market participants can communicate with the PJM Energy Management System through the Jetstream system. The connecting network is the Internet and the data protocol is DNP3. High levels of security are provided using Transport Layer Security and a Public Key Infrastructure. The site will need to procure a certified interoperable device or software package, an OATI-signed client certificate and an Internet connection at the remote site. Each data exchange is structured to meet the project’s needs. Fully redundant data link designs are supported for high levels of reliability.
