Grid operator

How it is used

In Europe the transmission grid is run by a transmission system operator (TSO) and local networks by distribution system operators (DSOs); in the US, ISOs and RTOs play a similar role. The grid operator dispatches plants, issues instructions, approves connections and publishes system data.
