Project Intro
About the Port Jefferson Power Station
The Port Jefferson Generation Facility provides reliable electricity to Long Island during peak demand periods. National Grid has operated the facility for 77 years, ensuring its safe, efficient, and dependable operation.
With a maximum capacity of 362 MW, Port Jefferson supports National Grid’s generation portfolio, which supplies more than 50% of the Long Island Power Authority’s energy on the highest-demand day.
National Grid remains committed to modernizing Long Island’s energy system while ensuring customers continue to receive safe and reliable power.

About the stack refurbishment
National Grid continuously evaluates its assets for maintenance. In staying up to date with today’s design standards, the top 120 ft of brick liner will be replaced due to deterioration of the original brick and mortar joints. Similarly, the exterior concrete shell also shows signs of typical concrete deterioration requiring reinforcement. It's important to repair, so the stacks can withstand high wind speeds and continue supporting the safe, reliable delivery of power to our customers.

Project Timeline
Explore the phases of the Port Jefferson Power Station stack refurbishment
Mar - Jun
Phase 1: Internal Liner Rebuild
The chimney stack is comprised of two main structural components, the concrete shell and the brick liner. During this phase, the upper portion of the chimney liner will be replaced with a new brick liner.
Jun - Sep
Phase 2: Exterior Shell Reinforcement
During this phase, a layer of carbon fiber will be added to the chimney’s concrete shell. This activity is necessary to maintain long term structural integrity and ensure we stay up to date with modern day design standards. The carbon fiber layer adds strength and a protective layer against weather.
Sep - Nov
Phase 3: Exterior Shell Coating
During this phase, we will restore the original aesthetic of the chimney by applying red and white striping to the shell exterior. This coating also provides UV protection to the carbon fiber layer resulting in a durable and long-lasting refurbishment of the chimney stack.
