Jefferson Power Station
Entergy Arkansas generation resources
Rendering is preliminary and subject to change
Entergy Arkansas is planning for a new generating asset with modern technology to meet the needs of our customers and enable us to maintain an “all-of-the-above” generation portfolio. The proposed Jefferson Power Station combined cycle combustion turbine, often referred to as CCCT, would be located adjacent to the White Bluff site near Redfield, Arkansas, bolstering reliability efforts and supporting anticipated load growth across Entergy Arkansas’s service territory.
Providing affordable, efficient and reliable power to industrial, commercial, agricultural and residential customers is what we do, meeting electricity needs today and planning ahead for years to come. With the addition of the Jefferson Power Station, we’ll build upon our well-established “all-of-the-above” portfolio of generating assets, currently including:
- Two nuclear generating units (Arkansas Nuclear One 1 and 2)
- Three coal-fueled generating units (White Bluff 1 and 2, Independence 1)
- Two hydroelectric plants (Remmel and Carpenter)
- One large natural gas-fueled steam electric generation station (Lake Catherine Unit 4)
- Three combined-cycle gas turbine generating facilities (Union Power Station, Hot Spring, Ouachita)
- Four solar facilities (Searcy Solar, Walnut Bend Solar, West Memphis Solar, Driver Solar).
Entergy Arkansas also purchases capacity and associated energy from the Grand Gulf Nuclear Station in Mississippi, has executed two Arkansas Public Service Commission-approved purchase power agreements, or PPAs, with Stuttgart Solar and Chicot Solar, and has APSC approval to add two new large renewable PPAs (Flat Fork Solar and Forgeview Solar) to its portfolio. We recently received APSC approval to build Lake Catherine Unit 5, a 446-megawatt natural gas-fired combustion turbine, that will replace Lake Catherine Unit 4.
Proposed natural gas generation station
Jefferson Power Station is a proposed natural gas-fired CCCT unit that is anticipated to produce approximately 754-megawatt (nominal capacity) of electricity Jefferson Power Station has been designed and is anticipated to be constructed in a way that supports customers’ sustainability goals and our path toward decarbonization. The proposed Jefferson Power Station is designed to operate as a base-load or load-following resource in response to system needs. The power source will also include modern emissions control systems.
Economic impact
Jefferson Power Station is anticipated to provide between 700 and 800 jobs during the peak of the construction phase. Entergy Arkansas anticipates sourcing these workers and vendors locally where practicable.
During the operational life of the resource, we anticipate employing at least 22 full-time employees to operate the facility and procuring outside services for project site maintenance such as land management and vegetation control, which is expected to have a local impact. Local businesses such as restaurants, stores and hotels could also benefit indirectly from the infusion of construction workers and activity during the construction portion of the project. Entergy Arkansas also will continue to support the local community through the payment of property taxes as well as through financial contributions to local non-profit organizations and employee volunteering in the community.
Proposed location
The planned footprint of the proposed Jefferson Power Station project includes approximately 45 acres located adjacent to the White Bluff facility and has been configured to mitigate impacts to natural and human resources as well as other obstacles or constraints. During the construction process, Entergy Arkansas plans to utilize approximately 100-acres of the existing site.

Notice to landowners
All landowners of record on or near the proposed project area will be notified by mail.
Several factors must be considered when embarking on a project of this scale, including:
- Construction costs – Construction costs are a major consideration in the design and approval of the project. This proposed project has been planned to utilize property owned by Entergy Arkansas, adjacent to the White Bluff plant. The property would be developed and repurposed to house the infrastructure necessary for Jefferson Power Station. Existing access points and current infrastructure would be used to the extent possible, which are anticipated to reduce the overall cost of the plant.
- Transmission line and facilities – No additional right-of-way is anticipated for the transmission line interconnection of Jefferson Power Station. The White Bluff 500kV substation would be altered to allow a new point of interconnection for the Jefferson Power Station 500kV gen-tie line within the boundary of Entergy Arkansas properties and facilities.
- Aesthetic considerations and other environmental factors – The proposed Jefferson Power Station unit would be constructed adjacent to the White Bluff units. The facility would not alter the current industrial land use. The proposed facility footprint is within an area that has historically been utilized for industrial purposes and was chosen to minimize environmental impacts.
- Health and safety – Safety is the highest priority for Entergy Arkansas. In accordance with the requirements set forth in the National Electrical Safety Code, Entergy Arkansas plans to construct and operate the proposed electrical facilities at its standard voltage design and observe reasonable safety precautions to ensure public safety. Construction methods and activities in the field must meet U.S. Department of Labor Occupational Safety and Health Organization requirements. In addition, Entergy Arkansas maintains and follows its own safety policies and procedures as part of the Entergy Enterprise Safety Standards.
- Regulatory and permitting – Entergy Arkansas will request a CECPN for the Jefferson Power Station from the Arkansas Public Service Commission. The Arkansas Department of Energy and Environment – Division of Environmental Quality (ADEQ), as well as other federal and state agencies, requires Entergy Arkansas to file for approval of various permits for construction of the proposed facility. Entergy Arkansas will apply for all necessary certifications and permits for the proposed facility.
Next steps
Construction phase – The proposed facilities would be designed and constructed under the direction and supervision of Entergy Arkansas consistent with state and federal law. Construction activities would include site soil preparation and installation of foundations, followed by erection/assembly of structural steel, power island equipment and auxiliary equipment/buildings.
