 THE FACILITY

The Cedar Bay Generating Plant is a 258 megawatt, coal-fired cogeneration plant located in Jacksonville, Florida. It provides electricity — enough for about 250,000 homes — to Florida Power and Light Company and up to 215,000 pounds of steam per hour to Smurfit-Stone Container’s adjacent recycled linerboard paper mill.

 TECHNOLOGY AND ENVIRONMENTAL PERFORMANCE

Power magazine, a leading industry trade publication, has called Cedar Bay "one of the cleanest and most flexible coal-burning cogen facilities in the world." For continuing to burn coal cleanly in Florida, Cedar Bay received Power's 1995 "Powerplant of the Year" award.

The plant operates three reheat circulating fluidized-bed (CFB) boilers fueled by low-sulfur coal. CFB boilers are one of the most advanced and proven technologies available today for burning coal cleanly. A circulating fluidized-bed contains a mixture of crushed limestone and coal suspended in a flow of hot air. The limestone (aragonite) strips the sulfur from the coal during combustion, minimizing sulfur dioxide (S02) emissions.

The coal arrives by bottom-dump rail cars at a rate of about two to three 90-car unit trains per week. The plant's solid waste ash is used beneficially for sludge stabilization.

To control emissions of nitrogen oxides (N0x), Cedar Bay uses selective non-catalytic reduction (SNCR) technology. The SNCR process introduces ammonia into the exhaust steam, splitting the nitrogen oxides into simple elemental nitrogen and water vapor, effectively reducing nitrogen oxide emissions to among the lowest levels for a coal plant in the United States.

As an added environmental benefit, the steam Cedar Bay provided to its steam host allowed the company to retire five old generating units that had been a major source of Jacksonville's air pollution.

Cedar Bay is designed to protect local water quality. Rather than using critical fresh water supplies for plant cooling, the plant uses treated wastewater from Smurfit-Stone Container. The zero-discharge water treatment system, one of the largest applications of this technology in operation in the U.S., recycles wastewater internally, preventing discharges to the Broward/St. Johns Rivers. Run-off from the coal and limestone piles is collected in a receiving pond, treated and re-used in the plant.

 OWNERSHIP AND MANAGEMENT

Cedar Bay Generating Plant is owned by Cedar Bay Generating Company L.P., an affiliate of National Energy & Gas Transmission, Inc.
