Overview
When a power plant is not in operation, many components within the plant are subject to corrosion. This is referred to as standby corrosion. Dehumidification for the power industry helps control humidity during shutdowns and minimize moisture-related corrosion. . A plant may be shut down due to planned or unplanned maintenance, or due to low seasonal power demand. Power plants have to be idled or shut down temporarily due to the following reasons:
- Maintenance or repair
- In case of breakdown
- Partial shut down due to excess capacity
- Extended cold standby (ECS)
Power plants have expensive auxiliary equipment that can be vulnerable to moisture-related deterioration and corrosion if humidity is not controlled during shutdowns. As a rule of thumb, it is best to maintain relative humidity levels at or below 35% RH to slow down the rate of corrosion.

Frequently Asked Questions
Dehumidification for power industry applications helps maintain controlled humidity in areas where excess moisture can affect equipment and maintenance work. It can be used during normal operations, planned maintenance, shutdowns, and equipment preservation to create a drier environment.
Power plant moisture control helps limit moisture exposure around generators, transformers, turbines, and other electrical or mechanical equipment. By controlling relative humidity and reducing the possibility of condensation, it helps maintain suitable conditions for critical equipment during operation and maintenance.
Power plant corrosion prevention focuses on reducing the moisture conditions that contribute to corrosion when equipment is idle or under maintenance. Maintaining controlled relative humidity during shutdowns can help protect metal surfaces and critical components from moisture-related deterioration.
TDS Asia provides industrial dehumidifier for power plant applications along with supporting equipment such as dehumidifiers, blowers and ducts. Its solutions can be used for equipment preservation, generator and transformer humidity control, pipeline drying, and other specialised power-plant applications requiring controlled humidity.
