Confidential Client – Repair of Cement Plant Power Distribution System

Location: New Orleans, Louisiana

Matrix PDM provided services to recommission part of a New Orleans area plant that had been idle for more than 10 years. The extensive power distribution system sat inactive and largely de-energized, with only a minor portion connected to feed the small cement terminal operation that remained.

The recommissioning required energizing enough of the power distribution system to supply approximately 10 MVA of various connected plant and process equipment loads. Matrix PDM developed a design to utilize elements that could be cost effectively reconditioned along with new equipment as needed.
