OSIsoft's PI system is a DTE Energy - Detroit Edison core technology. PI was installed first in a pilot plant in 1998 and has evolved into an Enterprise Agreement in 2007.
PI has allowed for information and application integration, and is the
enabling technology for DTE's performance center. The mission of the
performance center is to provide "real time and predictive asset
condition monitoring" for maximum asset value. Along with ABB's DCS,
OSIsoft's PI acts as the foundation of the control and technology
framework of DTE's fossil generation business unit. This enables
decision makers to make the right decisions when it matters.
