The Stanton Energy Center is located 12 miles southeast of Orlando, Florida. The 3,280 acre site contains Units 1 and 2, as well as Units A and B, and the necessary supporting facilities. http://www.psc.state.fl.us/utilities/electricgas/docs/2011_OUC_Site_Plan.pdf OUC has full authority over the management and control of the electric The Orlando Utilities Commission (OUC: "The Reliable One") is a municipally-owned public utility providing water and electric service to the citizens of Orlando, Florida and portions of adjacent unincorporated areas of Orange County, as well as St. Cloud, Florida, in Osceola County. OUC currently serves more than 250,000 customers.

Power Generation
A total of 2 coal-fired boilers, 3 combined cycle natural gas, a solar array, and landfill gas produce the electric power at the Stanton Energy Center.

Unit 1
Units 1 is a 460 MW Babcock & Wilcox boilers tied to Westinghouse steam turbines. Babcock & Wilcox Company fossil fueled steam generator to produce 3 million pounds of steam per hour at 1,000 F and 2,400 psi. Steam drum weighs 250 tons and has 7-5/8 inch thick steel walls. Total boiler weighs 4,750 tons and is supported from above by plate girders 80 feet long by 15 feet deep weighing 50 tons each. At maximum output each boiler will burn 154-191 tons of coal per hour. July 1, 1987. Operator: Orlando Utilities Commission. OUC has a 68.6 percent ownership share of this unit, which provides 302 MW of capacity to the OUC system.

Unit 2
Unit 2 commercial operation on June 1, 1996. Operator: Orlando Utilities Commission. OUC maintains a 71.6 percent (319 MW) ownership share of this unit.

Stanton A
Stanton A is a 2x1 duel fueled with natural gas as the primary fuel and No. 2 oil as the backup fuel, 656 MW Combined Cycle General Electric 7FA that began operation in 2003. OUC, KUA, FMPA, and SCF are joint owners of Stanton A, with OUC maintaining a 28 percent ownership share, KUA and FMPA each maintaining 3.5 percent ownership shares, and SCF maintaining the remaining 65 percent of Stanton A’s capacity. Stanton A is jointly owned by Southern Power, the Orlando Utilities Commission (OUC), Kissimmee Utility Authority (KUA), and Florida Municipal Power Agency (FMPA) yet operated by Southern Company. http://www.southerncompany.com/southernpower/pdfs/SP_fact_sheet_Stanton.pdf http://www.fmpa.com/index.php/power-generation/power-facilities/stanton-energy-center.

Stanton B
Stanton B Unit B is a 1x1 and consist of: one nominal 150 megawatts (MW) General Electric 7241 FA combustion turbine-electrical generator (CTG); a supplementary fired heat recovery steam generator (HRSG) with natural gas fueled duct burners; and a nominal 150 MW steam turbine generator (STG) for an overall nominal rating of 300 MW. Auxiliary equipment includes the following: a nominal 1,000,000 gallon tank for the storage of ultralow sulfur diesel (ULSD) fuel oil; a six-cell mechanical draft cooling tower equipped with drift eliminators; and a 205-foot exhaust stack. The unit operates primarily in combined cycle mode, meaning that the gas turbine drives an electric generator while the exhausted gases are used to raise steam in a heat recovery steam generator (HRSG). The steam is then fed to a separate steam turbine, which also drives an electrical generator producing additional electrical power. Operator: Orlando Utilities Commission. OUC is the sole owner of Stanton B.  http://www.dep.state.fl.us/air/emission/construction/ouc-stanton/TECHNICAL373A.pdf

Solar Array
The 5.9-megawatt (MW) solar photovoltaic (PV) farm, generates enough renewable energy to power more than 600 homes. OUC’s first solar farm tracks the sun as it moves across the Central Florida sky and generates clean power with its 25,172 panels. The Stanton Solar Farm came online at the Curtis H. Stanton Energy Center in late 2011, becoming the first solar farm in Orange County. Duke Energy and Regenesis Power LLC operate and maintain the 25-acre solar farm. http://www.psc.state.fl.us/utilities/electricgas/docs/2011_OUC_Site_Plan.pdf

Landfill Gas
In 2011, OUC and Orange County brought a new landfill gasto-energy facility online that recovers up to 22 MWs of additional landfill gas capacity from the landfill’s southern expansion site.

History
Chartered in 1923, OUC is the second largest locally owned electric utility in Florida and the 16th largest in the nation. The company is governed by a five-member commission (including the Mayor of Orlando), which is responsible for all operating policies.

Transportation and stockpiling
Coal arrives 5 times a week via 90 car unit trains from the Central Appalachian Mountains in Kentucky. Unit trains enter the site on 18 mile long railroad spur and is unloaded into a 400,000 ton capacity stockpile via enclosed conveyor belts. The coal is then reclaimed at 900 tons per hour by a stacker/reclaimer and conveyed to each boiled for firing.

Operational data
St. Clair is a base load power plant, dispatched after DTE Energy's Fermi 2 nuclear unit and the neighboring Belle River coal-fired power plant. Between 1999 and 2003, St. Clair's capacity factor averaged 57%, plant heat rate averaged 10,449 Btu/kWh, and the equivalent forced outage rate averaged 18%.

Costs
Unit 1 - $516 million with 20 percent for environmental protection measures. Unit 2 - $522 million with 20 percent for environmental protection measures.

Chimney
Pullman Power Products 550 feet high concrete steel chimney's with 355,000 brick liners.

Cooling Tower
Marley Cooling Tower Company hyperbolic natural draft 450 feet high concrete cooling towers.

Turbine/Generator
Westinghouse Electric Corp., single shaft, 3,600 RPM, tandem compound, two-flow, reheat condensing unit turbine to drive alternating current generator with output voltage of 24kV. Turbine produces 569,000 HP. Generator weighs 38 tons.

Connections to power grid
The transmission system consists of 32 substations interconnected through approximately 339 miles of 230 kV, 115 kV, and 69 kV lines and cables. OUC is fully integrated into the state transmission grid through its twenty-three 230 kV, one 115 kV, and one 69 kV metered interconnections with other generating utilities. http://www.psc.state.fl.us/utilities/electricgas/docs/2011_OUC_Site_Plan.pdf

The plant is connected to the power grid by 2 double circuit 345,000 and 5 120,000 volt transmission lines, owned and operated by ITC Transmission. The St. Clair has one 345 kV line (St. Clair-Lambton #1) and one 230 kV line (St. Clair-Lambton #2) that interconnect with Hydro One across the St. Clair River in Ontario, Canada. One of the wires of a 345 kV line enters a substation at the Belle River Power Plant.

Environmental Protections
Unit 1 - A Wheelabrator-Frye, Inc. electrostatic precipitator for fly ash removal from the flue gas. A Combustion Engineering, Inc. scrubber to remove 90 percent of the SO2 from the flue gas. Lined ponds and disposal areas to protect the ground water.

Unit 2 - A Wheelabrator-Frye, Inc. electrostatic precipitator for fly ash removal from the flue gas. An ABB Environmental Systems scrubber to remove 95 percent of the S)2 from the flue gas. A Noell, Inc. selective catalytic reduction system to limit nitrogen oxide emissions to no greater than 0.17 lb. NOx per 1 million Btu.

Sulphur dioxide
With its oldest unit dating back to the 1950s, the plant was ranked 74th on the United States list of dirtiest power plants in terms of sulphur dioxide emissions per megawatt-hour of electrical energy produced in 2006. Sulphur emissions could be lowered by using flue-gas desulfurization units, better known as SO2 "scrubbers", like those of Lambton Generating Station across the St. Clair River. Currently, these scrubbers are being installed at DTE's Monroe Power Plant, and may eventually be added at the St. Clair site as well.

Waste water
The Stanton Energy Center was designed to utilize recycled water from a nearby wastewater treatment plant for cooling and takes advantage of site stormwater in the air emissions control technology lessening any site discharge. http://www.ouc.com/Libraries/OUCDocuments/annual_report_2011.sflb.ashx
