DPC Capability Statement

The Dhofar Power Company Capability Statement represents a holistic picture of the electricity distribution network operated by Dhofar Power Company S.A.O.C (DPC) in the Dhofar Region; its current status, ongoing expansion and future development plans for the period 2017-2019 reflecting the circuit capacity, forecast of power flows, loading on each part of its Distribution System, and the associated fault levels. The statement also provides information on the anticipated future requirements to manage and/or realise the circuit capacity, optimum connection points, constraints foreseen, progress of on-going investment, and any other information deemed important from the perspective of an existing or potential user of the system.

The Statement provides an overview of DPC’s system, present and future, to a level of detail that is considered to be fit for purpose and suitably balanced. It includes information about the distribution network, its topology including all the components applied and used to develop the distribution system, such as overhead lines, underground cables or power transformers.

The statement dedicates a chapter to provide the Design Philosophies and Practices observed by DPC, reflecting on the Design and Operational Criteria and Technical Standards. Also provided is an overview of the Distribution System in terms of Load Management, Load Profiles, System Losses and Interconnections.

Summary of 2017-2019 Capability Statement
