In compliance with the Procedure for the System for the Communication, Execution and Control of Interruptibility,
published by ERSE in December 2010, REN, as Transmission System Operator (TSO), publishes the specifications of
the communications protocol between the central interruptibility control system of the TSO and the units to be
installed by consumers of electrical power who wish to provide the interruptibility service.
NOTE: The specifications may undergo slight changes as a result of adjudication of the central system.
