NRG Energy Powerton Units

Fortune 250 utility leader NRG Energy turned to MC Industrial/McCarthy to install environmental upgrades at the Powerton Generating Station in Pekin, Illinois. Holding the capacity to power more than 1.2 million homes, the 1,536-megawatt plant presented complex, large-scale coal fleet modernization job. NRG’s investment to modernize its Illinois coal fleet and dramatically reduce emissions prompted the power plant's upgrades. These types of projects maintain Combined Pollutant Standard (CPS) compliance—Illinois EPA-developed and Illinois Pollution Control Board-approved regulations. 

The project scope for the Powerton Generating Station included three key elements: air quality control system (AQCS) installations for two new Trona Dry Sorbent Injection (DSI) system units, as well as upgrades to Unit 5 and Unit 6.

Unit 5 Scope Details

• Fly ash storing and handling modifications
• Electrostatic precipitator (ESP) installation
• Balance of plant equipment and structures

Unit 6 Scope Details

• Fly ash storage modifications
• New perforated and hopper baffle plates and rappers at the inlet to the ESPs
• Installation fulfillment using a 2,500-ton crane

The project team sequenced construction to meet an aggressive outage completion window, while accommodating our concurrent project for the site. To help the client achieve their internal business goals, we presented an out-of-the-box execution strategy that provided the best overall value and an execution strategy that not only met the tight schedule but concluded the outage completion two weeks earlier than NRG's deadline.
