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 Instrumentation, Controls, and Electrical (IC&E) Technician supports the safe, reliable, and efficient operation of Plainfield Renewable Energy. This position provides advanced expertise in calibrating, testing, and troubleshooting instrumentation, control systems, and electrical equipment vital to plant performance. The role includes maintaining and optimizing PLCs, DCS, SCADA, and turbine control systems integrated with the boiler, biomass fuel handling systems, emissions controls, and the steam turbine generator.

Through skilled maintenance and system optimization, the IC&E Technician improves efficiency, reduces downtime, and ensures compliance with safety and environmental standards.

• Perform calibration, testing, installation, troubleshooting, repair, and maintenance of instrumentation and control systems, including PLCs, DCS, control valves, fan dampers, conveyors, fuel feed systems, variable speed drives, transmitters, analyzers, and biomass‑specific instrumentation to ensure reliable plant operation.
• Develop, update, and optimize PLC and DCS logic‑based controls—including ladder and P&—in coordination with engineering staff to improve automation and enhance plant efficiency.
• Carry out corrective, preventive, predictive, and emergency maintenance on electrical systems, including switch gear, motor control centers, transformers, motors, batteries, inverters, chargers, generator excitation systems, and variable speed drives.
• Calibrate and maintain precision instruments such as pressure and temperature transmitters and stack CEMS equipment and perform plant wiring repairs and installations using diagnostic tools including Amprobes, multimeters, and oscilloscopes.
• Use DCS and SCADA systems to monitor and maintain the efficient operation of boilers, steam turbine generators, and emissions control systems.
• Conduct turbine control system calibration and performance checks to ensure efficient start‑up, shutdown, and continuous operation of the steam turbine.
• Perform testing and tuning of boiler controls, combustion systems, turbine performance, and emissions reduction technologies to optimize plant performance and compliance.
• Coordinate contractors and vendors during outages and maintenance projects to ensure technical accuracy, schedule adherence, and safety compliance.
• Maintain accurate records of maintenance activities, calibration data, equipment modifications, plant drawings, and vendor documentation.
• Promote a strong safety culture by identifying hazards, applying safe work practices, and ensuring proper handling of hazardous materials in accordance with environmental and safety regulations.
• Support continuous improvement through root cause analysis (RCA), procedure refinement, reliability initiatives, and plant optimization efforts.
• Perform other duties as required to ensure the safe, efficient, and reliable operation of Plainfield Renewable Energy.
