Indianapolis Power & Light Company Project Success

Indianapolis Power & Light Company Project.jpg

On April 28, F.E. Moran Special Hazard Systems' project with AES Corporation, Indianapolis Power and Light Company, began service!

Purpose:  To provide an overview of the fire protection involved with the comprehensive design/build project with Indianapolis Power and Light Company.


  • Power plant conversion from coal to gas.
  • Fire Protection needs for an entire power plant.
  • POV of the project manager on this large job.

Indianapolis Power & Light Company is a combined-cycle gas plant that was converted from a coal-fired power plant.  The plant was two units of 200-MW coal-fired power generation.  The new plant more than triples the MW and is cleaner energy.

2x1 Combined Cycle Power Plant

A 2x1 combined cycle plant means that the plant was designed with two General Electric 7FA combustion turbine generators (CTG), two heat triple-pressure recovery steam generators (HRSG), one Toshiba steam turbine with hydrogen-cooled generator (STG), associated power block and balance of plant (BOP) equipment.

The Plant, Reinvented

The 650-MW combined-cycle gas turbine power station was a $636 million investment in Martinsville, Indiana.  F.E. Moran Special Hazard Systems had the pleasure of providing the fire protection for this power plant.

"We are committed to delivering to our customers the most cost-effective, environmentally friendly and reliable source of electricity.  Building a CCGT and refueling two of our Harding Street units will ensure our ability to meet the future needs of our customers and reduce our reliance on coal-fire generation," said Ken Zagzebski, President of AES' U.S. Strategic Business Unit (

Fire Protection for Indianapolis Power & Light

F.E. Moran Special Hazard Systems performed design/build in nine buildings for this exciting project.

Control/DCS/Electrical/Administration Building

  • Wet-pipe sprinkler system
  • Alarm and detection
  • Dry-pipe sprinkler system

Warehouse/Chemical Storage Building

  • ESFR wet pipe sprinkler system throughout
  • Alarm and detection throughout

Combustion Turbine Generators

  • Class III standpipe system throughout
  • Water mist suppression systems on gas turbines (this was supplied by another company, and we performed the interconnecting pipes with the fire alarm panels).
  • Fire alarm notification appliances and manual pull down stations; detection over lube oil skids; monitoring of fire alarm panels in PEECC and LEC enclosures

Steam Turbine Generator Building

  • Deluge system over lube oil area
  • Wet-pipe sprinkler system over turbine underfloor ground floor and mezzanine levels
  • Pre-action system for turbine bearings and exterior exciter cabinet.
  • Class III standpipe system
  • Fire alarm notification appliances and manual pull stations/detection

Power Distribution Center

  • Monitoring or alarm and detection

Aux Boiler

  • Alarm and detection

Water Treatment Building

  • Alarm and detection


  • Alarm and detection

Boiler Feed Pump Buildings (Unit 1&2)

  • Pre-action system throughout entire building
  • Alarm and detection

Continuous Emissions Monitoring System (CEMS) Enclosure

  • Monitoring of alarm and detection systems


  • Linear heat detection over ten transformers.

Cooling Tower

  • Dry-pipe sprinkler systems (2)
  • Alarm and detection

Water Pump House

  • Alarm and detection throughout

Fire Pump Enclosure

  • Monitoring of fire pump controllers, manual pull stations, notification

Working with Indianapolis Power & Light Company was a highlight for F.E. Moran Special Hazard Systems.  

This was a fun, and challenging project.  We were fortunate to have a scope of work that covered almost the entirety of the plant, allowing us to fully demonstrate our capabilities.  We were able to assist the general contractor in bringing the fire protection systems online in support of their start-up schedules, in addition to providing start-up support for fire protection systems provided by others.  An extremely rigorous piping specification added extra hurdles to the project, but F.E. Moran had the resources available to overcome the challenges.  Kudos to our designers, field crews, and alarm technicians for a successful outcome!
— Project Manager Jim Bouche

In Conclusion

F.E. Moran Special Hazard Systems got to be part of a project that tripled the energy the plant could previously make.  It is always a pleasure to be a part of something that does good for the community.  After the plant was converted to gas, it can now provide energy to over 100,000 homes and do it with less emissions than before.
