    Santan Expansion Project The expansion of Salt River Project's (SRP's) Santan Generating Station in Gilbert, Ariz., was selected as the 2006 Best Gas-fired Project due to the project team's ability to build a state-of-the-art generating unit while still meeting the environmental concerns of the plant's neighbors, as well as the state's strict regulations. The need to generate more power to meet the fast-growing electricity demands of the region known as the East Valley, prompted SRP to launch a two-phased expansion to increase the capacity of the Santan plant by 825 MW. SRP worked closely with project engineer Sargent & Lundy LLC and project constructor TIC (The Industrial Co.), as well as GE Energy, the equipment supplier. The expansion's first phase, which includes two GE Frame 7FA+e gas turbines and a D11 steam turbine, began service in April 2005. The second unit, a GE Frame 7FA+e gas turbine and GE's high-efficiency A14 steam turbine, entered service in March 2006, completing the project. From the beginning, limiting the plant's impact on the local environment was a priority. The F-class gas turbines are equipped with the latest emissions control devices, and, in addition, the existing GE gas turbines at the Santan site (Frame 7B units installed in the 1970s) were upgraded to Frame 7E models and dry low NOX (DLN) combustion systems were installed to reduce emissions. The Frame 7E controls were replaced with GE Mark VI systems required for DLN combustion. Upgrades also were required for the cooling towers and heat-recovery steam generators (HRSGs). In addition to the environmental performance improvements, unit heat rate improved by about 10 percent and unit output increased by approximately 20 MW. Natural gas was specified as the only fuel acceptable for power production. Plant visibility and noise were major public concerns when the expansion project was announced. To help reduce noise and obscure the plant from view, the new units are located behind a manmade, 25-foot tall berm, which features decorative walls and low-water-use ground cover plants. More than 1,000 trees were planted on the berm to further mask visibility. The power plants are set about 15 feet below grade, and to make the HRSG stacks less noticeable, they are arranged in an aesthetic triangular pattern. In addition, SRP has provided equestrian and bike paths that link neighborhoods north of the facility to the Town of Gilbert's Crossroads Park and SRP's canal system. In total, SRP has invested $20 million to improve the appearance and limit the environmental impact of the facility. Water is a major concern of every power project in the United States, but especially in the West. Wastewater from the Santan plant is treated and delivered to the Roosevelt Water Conservation District for irrigation purposes. In effect, the plant is a zero liquid discharge facility, since all wastewater is reused. The Arizona Corporation Commission approved the Santan expansion based on 34 initial conditions, and then added three more important stipulations: no high-polluting diesel fuel will ever be burned at the Gilbert site; SRP must review its plant operations and emission controls every five years, and make whatever upgrades are available with the latest technologies; and, the carbon monoxide emissions offsets must be achieved from the site, not elsewhere in the East Valley. The project has won the support of the local newspaper, the Arizona Republic, it was selected by the Western Council of Construction Consumers as a winner of a 2006 Distinguished Project Award in the utilities category, and was ranked highest in J.D. Power and Associates' 2006 customer satisfaction survey of the 76 largest utilities in the United States. Leiden Repower Project Leiden Power Station in the Nehterlands, owned by E.On Benelux Generation n.v., was selected as the 2006 Honorable Mention for the Best Gas-fired Project. One of the largest power producers in Europe, E.On operates five gas-fired power stations that together produce 1,850 MW of power and 558 MW hours of district heating. In addition, CO2 produced by the afterburning of the flue gasses within the plants is supplied to nearby greenhouses. By replacing the gas turbines at Leiden and increasing the power output of the existing generators, Lieden increased its power output by approximately 13 percent, while reducing its heat rate by about 18 percent. The Leiden plant, which is surrounded by residential and commercial properties, consisted of one Rolls-Royce Olympus SK30 gas turbine, a waste gas boiler and a steam turbine. Additional operations downstream produce the enriced CO2 gasses that are transported to the greenhouse district. Because of its urban location, tearing down the existing units and rebuilding was not feasible. A study revealed that the gas turbine electrical generator was capable of providing additional power, and that increasing the output of the gas generator would result in an increase in the plant's power output. E.On selected GE's LM2500+ gas turbines as the best-fit replacement of each gas turbine. The two plants were repowered in series, the first being repowered in January 2005 and the second in August 2005. The construction phase of the project consisted of the removal of the gas turbines, interfaces and controls from the existing plants. The remaining plant systems and structures, where necessary, were modified and/or adapted to the LM2500 systems. The LM2500 gas turbine and new controls and vibration monitoring systems were then installed. Lastly, the gas turbine flame detection system was installed to ensure proper and continuous combustion. Both repowering efforts were completed on schedule, in three months, and are both currently in operation. Based on the project's capital costs, E.On expects the payback period to be approximately three years.
