Electro-Mechanical Technician

Overview

Plainfield Renewable Energy (PRE) is a 37.5 MW wood biomass gasification power plant located in Plainfield, CT. Owned by Greenleaf Power and operated by NAES Corporation, the facility uses a single steam turbine and generator to produce renewable energy. PRE is equipped with advanced emissions control technologies, including a high-efficiency baghouse, and scrubbing systems to reduce NOx and sulfur dioxide.

The Electro-Mechanical Technician maintains, troubleshoots, and repairs a wide range of mechanical, rotating, electrical, and control systems that support reliable plant operations. The role includes performing predictive maintenance, calibrating, and testing instrumentation, supporting PLC and SCADA troubleshooting, and assisting with major equipment outages. The technician also contributes to overall plant performance by coordinating maintenance activities, ensuring safety and environmental compliance, and working closely with Operations, Engineering, and vendor teams.

Mechanical

• Perform maintenance, troubleshooting, and repair on mechanical and rotating equipment including pumps, valves, gearboxes, conveyors, bearings, fans, air compressors, and turbine auxiliaries.
• Inspect, align, overhaul, and install components associated with biomass fuel transfer systems, air-handling equipment, and steam cycle systems.
• Fabricate, modify, and install piping, supports, and brackets. Operate machine shop tools such as welding equipment, drill presses, lathes, and grinders to produce or refurbish components.
• Participate in predictive maintenance by tracking vibration, temperature, and lubrication parameters to detect mechanical degradation.
• Support facility shutdowns by assisting with planning and coordinating inspections and repairs of the gasifier, boiler, steam turbine generator, and auxiliary and process components.

Electrical / Controls

• Troubleshoot, repair, and maintain electrical systems—including motors, switch gear, MCCs, transformers, protective relays, and variable-frequency drives—while supporting low-, medium-, and high-voltage work in compliance with electrical safety and Lockout/Tagout (LOTO) requirements.
• Calibrate, test, and maintain instrumentation and control devices, and monitor system performance using tools such as multimeters, meggers, and HART communicators to identify abnormal conditions and initiate corrective actions.
• Maintain and troubleshoot excitation systems, battery chargers, inverters, and generator controls.
• Support PLC, DCS, and SCADA logic updates and troubleshooting, and perform field terminations, wiring, and loop checks.
• Support emissions control equipment (baghouses, scrubbers, CEMS) through calibrations, daily checks, calibration gas cylinder changes, and inventory monitoring to ensure environmental compliance.

Integrated Responsibilities

• Utilize the Computerized Maintenance Management System (CMMS) for scheduling, documentation, inventory management, and historical tracking.
• Support startup, shutdown, and operational testing of plant systems to ensure coordinated performance across electrical and mechanical disciplines.
• Collaborate with Operations, Engineering, and external vendors to plan, execute, and validate maintenance activities, and participate in root cause analysis (RCA), reliability improvement initiatives, and plant performance reviews.
• Uphold safety and environmental policies at all times, including hazard identification, proper PPE use, and adherence to all lockout/tagout, confined space, and hot work procedures.

Safety is a core value at NAES, and as a condition of employment, all employees are expected to remain mentally alert and work safely at all times. Employees must also adhere to all safety warnings and posted signs while on company property. Additionally, they are required to follow all NAES safety rules and procedures. Adherence to these safety responsibilities is one of the key factors in the evaluation of each employee’s performance.
