Scope of Work:

Armstrong International owns, operates, and maintains the utility assets, producing steam and compressed air, and maintains the corresponding distribution systems throughout the Heinz facility.

The powerhouse produces a peak of 205,000 lbs/hr of steam and 10,000 cfm of compressed air.

The Armstrong engineering team recognized and designed the upgrades to the electrical, steam, and compressed air systems.

Armstrong maintains a crew of six on-site employees who are responsible for the operation and maintenance of the utility assets and the steam and air distribution systems. This includes an Armstrong site supervisor who has overall responsibility for these systems including system efficiency, reliability, and reporting.

The agreement’s total value is in excess of $100 million. The financing was secured utilizing Armstrong’s strategic partners, Americas Power Partners/LaSalle Bank. The type of contract is an Energy Service Agreement.
