The Handbook for practitioners and decision makers seeks to raise awareness among utility managers, decision makers, and other stakeholders of the importance and benefits of developing robust operation and maintenance (O&M) strategies for existing and greenfield hydropower plants. This handbook also aims at providing guidance for ...
Operations, maintenance and refurbishment | Entura
Hydropower operations and maintenance costs are often 3–5% of the capital value of the asset. Over the life of the asset (possibly more than 70 years) this adds up to significant cost. Unforseen failures and poor performance will increase these costs even further. Time lost through breakdowns and forced outages can have significant commercial ...
Examples of substantial improvements in performance and cost reduction through managerial reforms are particularly illustrated in Case Study 1 (Statkraft''s Assets) and …
Chapter 7.
