As renewable energy markets mature, there may be an opportunity to revamp or repower ageing assets. In this report, we clarify the two approaches and discuss the best times to implement them.
This paper looks at revamping and repowering solar and wind plants, offering insight into the criteria utilised by Bluefield and the broader market to pinpoint optimal intervention timing. The rationale behind these benchmarks stems from comprehensive market research and Bluefield’s hands-on expertise. Furthermore, the passage underscores the benefits from the successful execution of revamping and repowering initiatives.
Revamping is the replacement of faulty or old components in distressed photovoltaic (PV) or wind farms that no longer correspond to their original specifications and are beyond the scope of product warranties. Concurrently, repowering strives to increase the system’s power capacity while remaining within the space limits of the existing plant. The following section outlines the essential metrics that trigger these interventions: low performance ratios, damaged components, leakage, decreased plant availability, and a drop in P50 capacity. P50 capacity represents the anticipated energy output that a renewable energy project is estimated to generate with a 50% probability under normal conditions.
By addressing these indicators, investors can leverage revamping to rejuvenate underperforming systems and repowering to augment capacity while minimizing costs. This is highlighted by real-world case studies that showcase the substantial gains achieved through these strategies, demonstrating their effectiveness in bolstering energy output, extending asset life, and enhancing investor returns.
Lastly, some of the key results of revamping/repowering are presented via case studies.
