1 April 2008 - Invensys Process Systems has won a substantial contract from the Saudi Electricity Company (SEC) to provide plant performance and monitoring solutions for use on one of the country's most critical power plants.
The PP8 plant is based in Central Province and is one of two power stations that supply capital city Riyadh with its electricity needs. The plant is currently rated at 1850 MW, which will rise to 2330 MW after this expansion.
The plant is currently controlled by four independent DCS systems, two from Invensys (Foxboro I/A) and the others struggling with obsolescence issues.
As part of the PP8 phase III expansion project, SEC has approved the plant's expansion with the addition of four new gas turbines to increase capacity by 480 MW.
The company was looking for a DCS that has the capability to control and monitor the new gas turbines, the overall balance of plant (BOP), and to provide a seamless interface with the existing DCS systems.
Invensys's solution is a Foxboro I/A DCS, together with the Plant Performance Monitoring Solution and a Foxboro RTU SCD5200 that will interface with the load dispatch centre based 400 km from the main plant.
Invensys is also to supply a Triconex system following a request from SEC for a valve shutdown safety system to be included in the project.
