Description & Challenges

Due to rapid growth of load in and around the Jeddah city, Saudi Electricity company proposed to construct a new indoor 380/110/13.8 kV Gas Insulated Substation named as Al-Samer (SMR) 380/110/13.8kV BSP. The new Al-Samer BSP is equipped with new protection, control, communication and Substation Automation System and is to be remotely controlled from Saudi Electrical Company's Power Control Center (PCC) through SAS and communication. The project has been delivered through Middle East Engineering and Development Company Limited (MEEDCO) on LSTK contract.

Major challenge encountered was in finalization the Site Grading of the substation in line with the SEC requirement. Considering the HV and MV Cables entry /exit from the substation and feasible access to substation buildings/equipment finalization of site grading had become a challenging task. With our technical expertise, DAR has provided a most viable and cost effective solution without compromising any technical requirement. Saudi Electricity Company has reviewed and accepted our proposal.

Scope:

Complete design and engineering services for Civil, architectural, structural, Electrical works, Protection relay coordination study, Mechanical works, including material B.O.Q. preparation, verifying / technical evaluation of vendor base and detailed design submittals, technical advisory support & preparation of final as built drawings. Also our scope involves performing Insulation coordination study to verify the switching and transient overvoltage surge.
