Romtec Utilities provided designs and pricing for Kings Mountain Energy Center and several others, giving Gemma Power a single partner for all its HRSG blowdown pumping systems in Kings Mountain, North Carolina. Kings Mountain is a suburban city in North Carolina that is within the Charlotte metropolitan area.

This city is located in Cleveland and Gaston counties and had a population of 11,142 at the 2020 census. It is about 7 miles north of the South Carolina border while being about 30 miles west of Charlotte.

Interstate 85 goes through this city, heading east to Charlotte while U.S. Route 74 also cuts through it.

Some of the area’s main attractions include Crowders Mountain State Park, Kings Mountain Gateway Trail, Kings Mountain Country Club, Big Red’s Café, The Pinnacle Mountain Peak, Los Tarascos, and Biscuitville.

The Kings Mountain Energy Center in North Carolina needed an HRSG blowdown pumping system for the power plant. The facility is a 475MW natural gas-fired combined-cycle power plant in Cleveland County. The energy center features an advanced Mitsubishi Hitachi M501GAC combustion turbine generator, a Vogt Power International supplementary fired heat recovery steam generator (HRSG) and a Toshiba America Energy Systems steam turbine generator.

The energy center will be capable of powering approximately 400,000 homes which will benefit surrounding communities.

Gemma Power, the owner, engineer, and contractor for the power plant construction contacted Romtec Utilities to request a quote for a private bid.

Having experience working with Gemma Power on previous projects, we provided a quote with our HRSG blowdown pump station designs and won the job.

This project also ran parallel to another HRSG blowdown pumping project for Gemma at their Middletown Energy Center.

Romtec Utilities provided designs and pricing for this project and several others, giving Gemma Power a single partner for all its HRSG blowdown pumping systems. After installation, Romtec Utilities sent an onsite technician to provide training to the operations personnel.

A new HRSG blowdown pump station required three industrial pump stations to provide water for its processes. This HRSG blowdown pump station needed to handle extreme pumping conditions.

The pumps were engineered outside the wet well in a vertical configuration to prevent damage from exposure to hot, caustic water created in the HRSG blowdown process.

This system uses Goulds 7.5 hp pumps in a duplex configuration to meet the high pumping rate required to handle the blowdown water. In the wet well, Nolta floats are the primary level-sensing equipment, and a pressure transducer is used to provide redundancy and to monitor the temperature in the well.

It can pump up to 480 gallons per minute with a total dynamic head of 35’.

Romtec Utilities as a designer, manufacturer, and supplier of HRSG blowdown pump stations was pleased to be a part of this large project at the Kings Mountain Energy Center in North Carolina for Gemma Power. We have partnered with them on many projects in the past for various power plants needing HRSG blowdown pump stations for these critical pieces of infrastructure that help power the U.S.

Our experience working and designing these HRSG blowdown pumping systems helps us design infrastructure that will last through difficult, hot water pumping conditions.
