Xcel Energy’s recent decision to convert the Harrington Generation Station from coal to natural gas marks a significant step towards cleaner energy solutions and reducing its reliance on coal. As a result the project was awarded a new 19 mile permit (10630) by the Texas Railroad Commission.
New Natural Gas Transmission Construction
- Pipeline Project: A new 19-mile, 24-inch steel pipeline will be constructed to serve the Harrington Powerplant. Located north of Amarillo, Texas, in Potter County, this pipeline will have:
- Class 1 Designation: The main pipeline section.
- Multiple Interconnects: Including a proposed interconnect site with El Paso Natural Gas (EPNG) and another with the Natural Gas Pipeline Company (NGPL).
- Harrington Delivery Site: The final delivery site at Harrington Powerplant, designated as Class 3.
- Pipeline Specifications: Designed for a Maximum Allowable Operating Pressure (MAOP) of 1,125 psig.
- Project Scope: Encompasses the design and installation of two proposed interconnects and one proposed delivery site at Harrington Station.
Pipeline Map
Below are the key points and highlights from the shift:
Conversion to Natural Gas
- Harrington Generation Station Conversion: Scheduled by 2025, this transition from coal to natural gas aims to reduce carbon emissions and meet regulatory requirements, especially concerning sulfur emissions.
- Operational Flexibility: The use of natural gas allows for more efficient start and stop operations, improving the plant’s ability to meet demand fluctuations effectively.
Renewable Energy Integration
- Cycling Practice: Xcel Energy prioritizes renewable energy, such as wind power, by shutting down the plant during high wind periods and restarting it when wind power is insufficient. This strategy helps in maximizing the use of renewable resources and minimizing emissions.
Future Plans and Leadership
- Expansion in Renewable Energy: Xcel Energy is enhancing its wind, solar, and battery storage capabilities, positioning itself as a leader in renewable energy.
- Exploration of Emerging Technologies: The company is investigating new technologies to further diversify and strengthen its renewable energy portfolio.
Retirement of Older Units
- Tolk Station Retirement: The coal units at Tolk Station are scheduled for retirement by 2028, along with the phasing out of older gas units. This move aligns with the industry’s trend towards sustainable energy practices to reduce environmental impact while ensuring a reliable power supply.
New Natural Gas Transmission Construction
