Hydropower plant flood restoration: three generators returned to operation

Following severe flooding at a major hydropower plant in Southeast Asia, BELFOR Thailand restored three affected generator units and associated electrical equipment. Two generators returned to full operation in May 2026, with the third following in September. The result: full generation capacity recovered without wholesale replacement of the affected equipment.

Flooding put critical power generation equipment at risk

In September 2025, prolonged heavy rainfall caused the facility’s reservoir level to rise rapidly. Emergency water discharge protected the dam, but water flooded the adjacent powerhouse across several levels. Three generator units were submerged.

Water, silt, oil contamination and high humidity affected electrical systems and other critical components. For the operator, the challenge went beyond cleaning up the damage. Every additional day of disruption put power generation capacity at risk.

Industrial restoration provided an alternative to replacement

BELFOR inspected the site in October and started restoration work on 17 November 2025. Working with the operator, OEM and subcontractors, the team developed a structured recovery plan for the affected equipment.

Specialists decontaminated electrical and electronic equipment, generator components and isolated phase bus ducts. They also cleaned electrical cables, removed moisture and decontaminated affected powerhouse areas. The project developed from an initially planned two-week engagement into 43 weeks of recovery support.

Three generators restored and full capacity recovered

Two higher-capacity units returned to full operation in May 2026. The third followed in mid-September 2026. This restored the facility’s full power generation capacity.

For industrial companies, insurers and loss adjusters, the project demonstrates an important principle after major technical losses: damaged equipment does not automatically need to be replaced. Specialist restoration can preserve existing assets, shorten the path back to operation and avoid the cost and lead time associated with wholesale replacement.

3 generator units restored. 43 weeks of project support. Full operational capacity recovered.

This is where technical restoration becomes a business continuity tool. The objective is not simply to clean damaged machinery. It is to recover critical assets, get operations running again and reduce the financial consequences of downtime.
