Northside Generating Station

Northside Generating Station (NGS) is located in north Jacksonville in an environmentally sensitive area surrounded by wetlands. The plant uses natural gas, fuel oil, biomass, coal and petroleum coke in three large steam units and four small diesel-powered peaking units to produce more than 1300MW of peak electric capacity.

• Unit 1 was commissioned in 1966 (fueled with oil and natural gas) and repowered in 2000.
• Unit 2 was commissioned in 1972 (fueled with oil and natural gas), decommissioned in 1984 and repowered in 2000.
• Four simple cycle combustion turbines were commissioned in 1975 (fueled with diesel oil).
• Unit 3 was commissioned in 1977 (fueled with oil and, later, natural gas) and is scheduled to be retired after 2026.

Units 1 and 2 were awarded the Top Plant Award in 2012 from Power Magazine for ten years of continuous improvement to top tier performance.

Circulating Fluidized Combustion

The need to improve combustion efficiency and the desire to burn a wider range of fuels along with the need for additional base load capacity, led to the repowering of Units 1 and 2 in 2000 with two of the largest Circulating Fluidized Bed Combustors (CFBs) in the world (at the time). They are both clean and fuel-diverse, affording JEA the flexibility to utilize the most economic fuel choices while still achieving exceptional emission levels. The CFBs have in-cycle sulfur capture (S02) with limestone injection and Spray Dryer Absorber along with low temperature operations resulting in NOx reduction making them among the cleanest solid fuel plants in the world.

JEA recently gave a tour of our advanced clean coal technology to a delegation from Newcastle Municipality, South Africa. Mayor A. Rehman and his team toured JEA'S Northside Generating Station, which uses Circulating Fluidized Combustion. This combustion technology is new in South Africa.
