Core Responsibilities

Primary Functions

Execute complex preventative, predictive, and corrective maintenance on large hydroelectric turbines (Kaplan, Francis, Pelton) and associated generators, ensuring maximum reliability and performance.
Perform precision alignment of rotating equipment, including turbines, generators, pumps, and motors, using laser alignment systems and traditional methods to minimize vibration and wear.
Disassemble, inspect, repair, and reassemble major powerhouse equipment such as turbine runners, wicket gates, bearings, shafts, and seals during planned outages and emergency situations.
Troubleshoot and diagnose complex mechanical, hydraulic, and pneumatic system failures on governors, brake systems, high-pressure hydraulic units, and compressed air systems.
Operate, inspect, and maintain heavy lifting equipment, including overhead bridge cranes and mobile cranes, for the safe movement and positioning of large components.
Perform welding (SMAW, TIG, MIG), cutting, and fabrication tasks to repair equipment or create custom components as needed, adhering to strict quality and safety standards.
Conduct detailed inspections and maintenance on high-pressure penstocks, intake gates, valves (butterfly, gate, spherical), and other water conveyance structures.
Utilize a wide range of precision measurement tools, such as micrometers, calipers, dial indicators, and torque wrenches, to ensure components meet strict engineering tolerances.
Interpret complex engineering drawings, blueprints, schematics, and technical manuals to guide maintenance activities and troubleshooting efforts.
Install, maintain, and repair various plant auxiliary systems, including cooling water systems, lubrication oil systems, drainage pumps, and fire protection equipment.
Document all maintenance activities, inspection findings, and repairs meticulously in the Computerized Maintenance Management System (CMMS) for historical tracking and regulatory compliance.
Lead and participate in major unit overhauls, coordinating with other trades, engineers, and contractors to ensure projects are completed safely, on time, and within budget.
Perform non-destructive testing (NDT) such as dye penetrant or magnetic particle inspection to identify cracks or defects in critical metal components.
Maintain and repair large-scale hydraulic systems, including accumulators, cylinders, and control valves, that operate gates, brakes, and turbine controls.
Implement and strictly adhere to all safety procedures, including Lock-Out/Tag-Out (LOTO), confined space entry, fall protection, and hot work permits.

Secondary Functions

Support ad-hoc repair tasks and provide mechanical support for capital improvement and plant upgrade projects.
Contribute to the continuous improvement of maintenance procedures and strategies by providing feedback and suggestions from the field.
Collaborate with operations staff to diagnose equipment issues and schedule appropriate maintenance windows to minimize generation impact.
Assist in managing the inventory of spare parts, tools, and materials, identifying needs and initiating procurement requests.
Participate in root cause analysis (RCA) investigations for equipment failures to identify underlying problems and prevent recurrence.
Mentor and provide on-the-job training for apprentices and less experienced mechanics, fostering a culture of knowledge sharing and skill development.
Maintain a clean, organized, and safe work environment in the shop and throughout the powerhouse.
Respond to emergency call-outs as required to address urgent equipment failures outside of normal working hours.
