A hydropower plant’s fire risk concentrates in specific, high-value equipment rather than being distributed across a building the way a commercial facility’s risk typically is: generator windings, step-up transformers, and switchyard equipment carry both high fire-consequence (equipment replacement cost and extended downtime) and, given many hydropower facilities’ remote locations, meaningfully longer emergency-response times than an urban facility would face. NBC 2016 Part 4 provides the general national fire-safety baseline, but power generation facilities typically follow additional facility-specific fire protection design guidance for transformer and generator fire risk given the specialized suppression needs (often including transformer-specific water-spray or foam systems distinct from general building fire suppression). At a hydropower plant in Dhauliganga, Uttarakhand, Elion’s fire safety audit assessed transformer and generator area fire protection adequacy, control room detection systems, and — given the facility’s remote location — on-site emergency response capability and coordination time with the nearest external fire service.
Remote-location power generation facilities carry a distinct fire-safety consideration most urban commercial audits don’t need to weight as heavily: on-site suppression and detection capability needs to be more self-sufficient given that external fire service response time may be substantially longer than in a city, making the facility’s own systems the primary (not backup) line of defense for a meaningful window of time. This case study covers the specific findings from the Dhauliganga hydropower plant’s fire safety audit and the corrective priorities recommended.
Hydropower fire risk concentrates in generator windings, step-up transformers and switchyard equipment — high-value, specialized-suppression-need assets. Remote locations mean on-site systems are the primary line of defense, not a backup to external fire response, for a meaningful window of time.

Overview of the Dhauliganga Hydropowerplant
The Dhauliganga Hydropowerplant is situated on the Dhauliganga River, a tributary of the Alaknanda River. It is located in the Chamoli district of Uttarakhand, India. The plant has a total installed capacity of 280 MW, which is generated by four units, each with a capacity of 70 MW. The power generated by the plant is transmitted to the national grid through a 220 kV transmission line.
The infrastructure of the Dhauliganga Hydropowerplant includes a dam, an intake structure, a desilting chamber, a power house, and a tailrace channel. The dam is constructed across the Dhauliganga River to create a reservoir that stores water for power generation. The intake structure diverts water from the reservoir into the desilting chamber, where sediments are removed before entering the power house. The power house contains four generating units that convert the potential energy of water into electrical energy. Finally, the tailrace channel carries the water back to the river after passing through the turbines.
Importance of Fire Safety in Hydropowerplants
Hydropowerplants pose several potential risks and hazards that make fire safety measures crucial. One significant risk is related to electrical equipment and wiring. The power house of a hydropowerplant contains a vast array of electrical equipment, including generators, transformers, and control panels. Any malfunction or short circuit in these components can lead to a fire. Additionally, the presence of flammable materials such as lubricants and fuels further increases the risk of fire.
Another potential hazard in hydropowerplants is the storage and handling of hazardous materials. These plants often store large quantities of lubricants, fuels, and chemicals for maintenance and operation purposes. If not stored properly or handled with care, these materials can ignite and cause a fire. Moreover, the presence of oil and grease in the power house can create a flammable environment if not managed effectively.
Fire safety measures are essential in preventing accidents and ensuring the safety of workers and the environment. In the event of a fire, the lives of workers are at risk, and the damage to property can be extensive. Moreover, fires in hydropowerplants can have severe environmental consequences. The release of toxic gases and pollutants into the air and water bodies can harm ecosystems and pose health risks to nearby communities. Therefore, it is crucial to implement robust fire safety measures to prevent fires from occurring and mitigate their impact if they do occur.
Fire Safety Audit: Definition and Purpose
