3. 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

4. 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

5. 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 Calpine IS Operations Engineering Services – Solutions at the Speed of Business
