POWER replaced existing outdated control and instrumentation systems for Units 7 and 8 at the plant. Unit 7 is a 30-MW pulverized coal or natural gas-fired unit. Unit 8 is a 65-MW pulverized coal-fired unit. Units 7 and 8 are also equipped to burn 17% and 20% refuse, respectively. Services included the preparation of the controls upgrade study, preparation of equipment and installation specifications and drawings, as well as the design and testing of the application software for the control systems and operator interface. Specifications were also prepared for the procurement of field devices and instruments such as flame scanners, transmitters, I/P positioners, and other miscellaneous device.
