Operations Forum

Contact owners and managers

1–30 of 83

Focuses on the technologies and applications of capital plant equipment, including control systems, metering and measurements. Both suppliers and plant technicians will benefit through peer exchange and education on the latest innovations in control technologies. As fuel costs, environmental regulations and electricity deregulation continue to impact the energy industry, the ability to improve and optimize operations becomes increasingly valuable to private and public district energy providers. The Operations Forum meets at the IDEA Annual Conference.
Chair: Juan Ontiveros, University of Texas-Austin.
