Emergency Power & Peak Shaving System

Innovative Solutions

ITAC was selected for this $1.6M project involving the turnkey supply and installation of a custom 2.4 MW power system capable of backing up HRRSA’s entire 25 KV underground distribution circuit, which serves a critical water treatment plant in Harrisonburg, Virginia. ITAC provided all disciplines of engineering, software integration, control system design, power system device programming, startup and commissioning services as well as the electrical and mechanical/rigging construction services.

The power system is capable of continuous utility parallel operation for reducing the customer’s utility demand during peak load curtailment periods.  We installed three Caterpillar 800 KW 480V generators in sound-attenuating outdoor enclosures, a 480V three-engine generator paralleling control system, dual redundant Operator Interface touch screen systems, a step-up transformer, and a 25KV main utility circuit breaker and synchronizing system. Our Power Systems group designed and built the generator paralleling control system as well as the 25KV utility circuit breaker system in our switchgear and control panel facility located in Chester, Virginia.

Assured Success

ITAC’s design build approach brought speed and total coordination to the owner’s project. The project required close coordination with the electric utility to ensure both peak shaving and emergency power backup for the site.  Permitting was a challenge as the site was incorrectly classified in the 100 year flood plain and required amendments before permits could be issued. The power system controls were integrated with the customer’s existing SCADA system to allow for complete remote control, monitoring and alarming of any real-time event.  ITAC commissioned the entire power system within a tight outage window allowed by the customer and currently provides maintenance and extended warranty services for this power system.
