Abstract: This paper discusses the latest developments in Electronic District Control which are being used or are about to be used within the North Scotland District of British Gas Transco. North Scotland has a history of innovative use of electronics in controlling District Pressures and was the first district in Scotland to install an Electronic District Control System in Dunfermline in 1985. The Dunfermline system was based on the Wales Electronic District Control system and is still in use today although the technology is showing its age.

This system uses mains powered governor and outstation systems and communications systems running at 300 baud (about 30 characters per second). This compared to the present systems which are battery and solar powered and can run at speeds of up to 28,800 baud (2,880 characters per second) a 9 times speed increase. The company recognizing that the authors could not go on developing different Electronic District Control systems has now adopted the Engineering Research Stations Electronic District Control System as the preferred system to be used by British Gas. This system now accounts for approximately 36% of all systems installed.
