Asset Reliability and Efficiency
Hydropower facilities require regular and systematic assessment and maintenance to ensure adequate reliability and efficiency over time.
Operating conditions should be continuously monitored and recorded. Intrusive inspection and maintenance activities are required in order to achieve the expected asset life. These activities need to be complemented by a well-tailored programme of preventative maintenance, condition monitoring and testing.
Adhering to good practice ensures that hydropower assets are maintained to deliver optimal performance in the short- and long-term, in accordance with the overall electricity generation and supply strategy of the owner or operator.
Understanding good practice
International industry good practice in asset reliability and efficiency for hydropower projects is defined in the Hydropower Sustainability Guidelines on Good International Industry Practice (HGIIP).
The guidelines were published by the International Hydropower Association and are governed by the Hydropower Sustainability Assessment Council, a multi-stakeholder group of representatives of civil society, industry, governments and financial institutions.
Assessing project performance
Two assessment tools are available to measure hydropower project performance:
The Hydropower Sustainability Assessment Protocol (HSAP) is used by independent accredited assessors to consider whether a project has achieved good and best practice at different stages of its life cycle. Asset Reliability and Efficiency is addressed in O-5 for the operation stage.
The Hydropower Sustainability ESG Gap Analysis Tool is used by independent accredited assessors to help project teams address any gaps against good practice in environmental, social and governance topics across 12 assessment sections. Asset Reliability and Efficiency is not addressed in the HESG Tool.
