Calpine IS Operations Engineering Services – Solutions at the Speed of Business Calpine and their history with PI Calpine standardized on PI as their operations historian in early 2001 Prior, a mix of control system historians and embedded historians were used The data gathered by these devices could not easily and efficiently be transmitted external to the facility Higher risk of invalid or untimely data being used to support business decisions The amount of historical data available was also limited to the type of historian installed

Calpine IS Operations Engineering Services – Solutions at the Speed of Business What will you see in this presentation? Calpine has used PI to integrate data between many systems throughout the enterprise. We will highlight our implementation infrastructure Our Team Responsibilities How PI is leveraged to support business functions A focus on Continuous Emissions Monitoring How we monitor PI systems in our enterprise Question and Answers opportunity

Calpine IS Operations Engineering Services – Solutions at the Speed of Business Calpine’s PI Infrastructure PI is installed at 79 of Calpine’s 82 generating facilities We have 55 production PI servers and 24 PI API nodes Not all sites require a production PI server, so API nodes are installed and interfaced with a production server We installed 37 PI systems in 2001, 41 in 2002, and 1 so far in 2003 PI is a standard installation at all generating facilities
