Manager-Maintenance Power Generation

Overview

The Maintenance Manager is responsible for leading all maintenance activities at the Tallgrass Cheyenne Energy Center—an off‑grid, large‑scale AI‑dedicated critical power, multi‑unit generation campus that will initially produce approximately 2.5 GW of capacity with expansion capability up to 10 GW from a fleet of simple‑cycle gas turbines and combined‑cycle gas turbine (CCGT) technologies. The role ensures safe, reliable, and cost‑effective maintenance across mechanical, electrical, and instrumentation & control disciplines while driving asset integrity, availability, and long‑term performance.

• Develop and execute the site’s maintenance strategy—including PM, PdM, CBM, and corrective maintenance—to align with Tallgrass Energy’s safety, compliance, reliability, and cost objectives.
• Lead and mentor a multidisciplinary maintenance workforce, fostering a strong safety culture and high‑performance work environment.
• Drive continuous improvement using RCM, RCFA, Lean methodologies, and reliability analytics.
• Strategically oversee maintenance activities across integrated combined‑cycle systems, including gas turbines, HRSGs, steam turbines, condensers, cooling systems, and balance‑of‑plant assets.
• Ensure alignment of maintenance strategy with combined‑cycle operating modes, including baseload, cycling, and frequent start/stop duty.
• Maintain compliance with applicable codes and standards for steam systems, pressure vessels, and HRSG components.
• Coordinate with Operations, Planning & Scheduling, and Engineering to balance maintenance execution with dispatch requirements and operational constraints.

• Lead major and minor outage planning and execution for gas turbines, steam turbines, HRSGs, and balance‑of‑plant systems.
• Manage OEM relationships and Long‑Term Service Agreements (LTSAs), ensuring scope clarity, warranty stewardship, and high‑quality execution.
• Oversee all work management processes in IBM Maximo, including planning, scheduling, job kitting, permit coordination, backlog management, and work history quality.
• Integrate outage planning and execution to minimize risk to availability and thermal fatigue.
• Coordinate outage timing with Operations to support grid commitments and market dispatch requirements.

• Lead PdM programs, including vibration analysis, oil analysis, thermography, ultrasonic testing, and borescope inspections.
• Maintain the integrity of rotating equipment, HRSG pressure parts, fuel systems, electrical systems, and I&C assets.
• Utilize Emerson Ovation system data and historian trends, and the Emerson simulator for troubleshooting, root‑cause investigations, and reliability enhancement projects.
• Ensure compliance with Tallgrass’s Management of Change (MOC) process, including documentation updates, drawing control, and configuration management.
• Drive reliability improvement initiatives addressing combined‑cycle failure modes such as HRSG pressure‑part degradation, condenser performance losses, steam turbine vibration, and startup‑related damage.

• Ensure full compliance with OSHA, NFPA 70E, LOTO, confined space, and hot work requirements.
• Collaborate with EHS to maintain site environmental compliance, including air permit obligations, CEMS support, and emissions readiness during outages.
• Ensure adherence to OEM standards, ASME/API codes, pressure vessel integrity programs, and jurisdictional inspection rules.
• Support NERC‑related maintenance activities as applicable.
• Support environmental compliance for combined‑cycle assets, including SCR systems, ammonia handling equipment, and CEMS readiness.

• Develop and manage annual maintenance O&M and capital budgets, outage cost forecasts, and long‑term maintenance plans.
• Lead vendor qualification, scope development, contract negotiations, and performance management for contractors, OEMs, and specialty service providers.
• Optimize spare parts strategy and storeroom management, focusing on critical spares, long‑lead items, and inventory accuracy within Maximo.
