CLP has adopted a structured asset management framework that consists of a set of systematic and coordinated practices, through which the company optimally and sustainably manages its assets and associated performance, risks and expenditures over their life cycles. In 2007, CLP became one of the first few Asian companies to receive the PAS 55 compliance certificate, the first international standard issued by the British Standards Institute on the optimal whole-life management of physical assets.
The planning of CLP’s supply network is an important part of the asset management cycle to ensure that timely and cost effective investments are made to meet the demand for electricity. CLP puts together a 10-year forward looking network development plan every year according to the latest public/private development projects and load growth forecast.
To optimise the performance of our assets throughout their life cycles, CLP is migrating towards a condition-based maintenance approach that combines predictive and preventive maintenance with condition monitoring techniques to detect potential fault conditions in advance of failures, making maintenance a proactive process. In addition to gathering equipment condition data during regular inspections, CLP is also adopting online condition monitoring for real time surveillance and diagnosis of the health conditions of the critical transmission and distribution equipment.
In the wake of super typhoons causing blackouts in North America and Asia Pacific, CLP has conducted a comprehensive risk assessment on their impact on the transmission and distribution network. The two most significant risks include potential damage of the 400kV pylons at windy locations and potential flooding of substations in low lying coastal areas. A special project was launched to strengthen the structures and foundation slopes of selected 400kV pylons. Flood mitigation measures were also implemented at the flood-prone substations. A system was developed to identify potential substations at flood risk due to storm surge.
