A Tour of LG&E & KU's Trimble County Generating Station

During the Republic Bank Foundation Junior Achievement (JA) Achievers Auction, David Deans, Genscape's CFO, bid and won a tour of LG&E and KU’s Trimble County Generating Station for the Louisville Data Integrity Power team.  This auction was one of the main fundraisers for the local chapter of JA, an organization Genscape is committed to supporting. As mentioned on their website, JA works directly with local schools to “foster work-readiness, entrepreneurship and financial literacy skills, and use experiential learning to inspire students to dream big and reach their potential.”

The Trimble County plant is LG&E’s newest and is situated on over 2,200 acres of land along the Ohio River in Trimble County, 50 miles northeast of Louisville. It's one of the most environmentally friendly and technologically advanced coal-fired plants in the country. Below is a photo of the plant landscape. 

Twenty six of Genscape’s employees from across all of our offices came together for an educational and fun field trip to the plant on June 4th.  The tour began in downtown Louisville on the 23rd floor of the LG&E building for a short orientation hosted by David Sinclair, VP of Energy Supply and Analysis. The group then boarded an LG&E chartered luxury bus for the hour long ride to the power plant.  

At the plant, the Genscape group met with the plant manager, Jeff Joyce, and several other members of the Trimble County team.  After an overview of the plant operations, the tour group was able to ask several questions and then broke up into 4 teams to go on group tours led by experienced members of the Trimble County plant staff.  To ensure safety, everyone donned hard hats with internal radios and protective glasses.

The groups were able to get up close to the coal generating units and were also able to see the gas units from several different vantage points on the plant property.  The coal-fired units consisted of the 514 MW Trimble County 1 (TC1), which was operating at the time of the tour, and the 760 MW Trimble County 2 (TC2), which was in an unplanned extended maintenance outage due to a tube leak.  

The teams learned about and saw the sophisticated emissions reduction systems that are on TC1 and TC2.  TC1 is equipped with:  low-NOx burners and selective catalytic reduction (SCR) equipment that reduce NOx emissions; a dry electrostatic precipitator (DESP) that reduces particulate emissions; a hydrated lime injection system that reduces sulfur trioxide; and a wet limestone flue gas desulfurization (FGD) unit that reduces sulfur dioxide emissions.  In addition this emissions reduction equipment, TC2 also has a carbon injection/baghouse system to reduce mercury emissions and a wet electrostatic precipitator (WESP) for small particulate and acid mist reduction.  The 6 gas-fired units were simple cycle combustion turbines each rated at 160 MW. Most of those units were offline during the tour due to lower load demand that day, but one unit did run briefly.  

In addition to the generating units, the tour also highlighted the plant’s coal and limestone delivery systems, the new landfill being built for coal combustion residuals, the transmission line system connected to the plant, how the coal by-products of fly ash and gypsum are recycled and used by other businesses, and the on-site wildlife preserve. 

The plant tour lasted approximately 3 hours and was followed by another question and answer session led by Jeff Joyce.  Once the tour was complete the Genscape teams got back on the bus and made the one hour drive back to Louisville. For a group of Genscape employees that works hard to deliver real-time power data that truly moves markets, getting up close and personal with one of the generating plants was a fun and educational experience.
