After review of the current ANSI/ISA-77.43.01, Fossil Fuel Power Plant Unit/Plant Demand Development - Drum Type, standard at the meeting in early June 2013, ISA77.43 members decided that a revision of the standard is necessary. The committee is seeking additional members to contribute to this work and to provide input.

The standard establishes the minimum requirements for the functional design specifications of unit/plant demand development for control systems for drum-type fossil-fueled power plant boilers. The scope of the standard is to address the unit/plant demand development subsystem for boilers with steaming capacities of 200,000 lbs/hr (25 kg/s) or greater.

If you are interested in participating in this revision, or for more information, please contact

The initial work and review of the standard will be handled through email, teleconference, and web meetings, with a face-to-face meeting most likely in conjunction with the 2014 Power Industry Division Symposium.
