feature three LM6000-PF aeroderivative gas turbines. “As the first project in Turkmenistan using our
aeroderivative technology to produce power in power plants, Çalık Enerji is leading the way in helping to address the increasing power demands in the country using proven technology,” said Darryl Wilson, vice president and chief commercial officer - distributed power for GE Power & Water. “Te flexibility, fast-start capabilities and overall performance of our LM6000 units will help provide reliable on-site power for the region.” GE’s innovative LM6000 aeroderivative gas turbines operate at high reliability and flexibility and are capable of zero water consumption while achieving lower emissions compared to other units in their class. Te LM6000 offers reliability of greater than
99 per cent and availability of more than 97 per cent, along with a high level of operating flexibility and proven dry low nitrous oxide (NOx) emissions technology that guarantees NOx emissions as low as 15ppm at 15 per cent oxygen. Te machine’s high efficiency enables lower fuel consumption per unit of power output than competitive technologies, notes the company, yielding fuel cost savings and carbon dioxide reductions for turbine operators.
Compressed air energy storage Dresser-Rand has won a contract from Apex Compressed Air Energy Storage for the supply of equipment to be used in a new 317MW compressed air energy storage (CAES) facility to be constructed near Tennessee Colony, Texas, in the Electric Reliability Council of Texas (ERCOT) market. Te Apex Bethel Energy Centre would be the first CAES facility to be built in the USA since the Power South facility in McIntosh, Alabama, in 1991. Tis also uses Dresser-Rand turbo machinery. Te company says the latest contract is worth approximately US$200 million (€150 million).
Vincent R Volpe Jr, president and ceo of Dresser- Rand, says the project is of both financial and strategic significance to the company. “First, it validates the view that the value of large energy storage in the form of CAES is a viable economic investment. Secondly, we are pleased that we have been chosen by Apex on this important project, which we believe will lead to further CAES projects in the coming years. We believe this order represents the first step in the development of a compelling market opportunity,” he said. According to Jack Farley, president and ceo of
Apex, Dresser-Rand had the most proven technology and experience. “Te flexibility of SMARTCAES technology makes Dresser-Rand a clear choice to provide the equipment and life cycle services. Tey have a unique cycle and equipment design that has proven itself over 22 years of successful CAES operations. Te flexibility of this cycle provides industry-leading dispatch flexibility and low cost, in compliance with air emissions requirements over an expansive operating range. We believe this contract will be the start of a long-term, successful relationship with Dresser-Rand for this project and others to come, both in the US and elsewhere around the world,” he added.
Re-emerging technology Meanwhile, Jim Heid, Dresser-Rand’s senior vice president for CAES development, believes this power generation technology is on the cusp of re-emerging: “A CAES system provides two different services either sequentially or concurrently - high pressure air compression and electric power generation derived from expanding the compressed air. Industry sources estimate that there are more than 40 such projects being contemplated over the next 5-10 years. A number of these potential projects are linked to growth in renewable power generation sources such as wind and solar farms.” If all goes to plan Apex’s CAES plant will have
Gas turbine driven pipeline compressors for Kazakhstan R
olls-Royce has won a US$175 million (€132 million) contract to supply Asia Gas Pipeline (AGP)
with equipment and related services to power the flow of natural gas through Kazakhstan’s Line C gas pipeline, part of the 1833km long Central Asia-China gas pipeline network. The company will supply AGP, a
joint venture between Kazakhstan’s KazMunaiGaz and China’s National Petroleum Corporation (CNPC), with twelve RB211 gas turbine driven pipeline compressor units which will operate at four compressor stations along the

1115 km Line C Pipeline. When it reaches full operating capacity in 2016, the Central Asia-China Gas pipeline network will transport up to 55 billion m3
/y of gas from Turkmenistan
and Uzbekistan, through Uzbekistan and Kazakhstan to China. The Line C pipeline in Kazakhstan will contribute up to 25 billion m3
/y of the total capacity,
including potential to supply gas domestically to the Republic of Kazakhstan. The contract is in addition to an award
for eleven RB211 gas turbine driven pipeline compressor units secured by
Rolls-Royce in 2009 for AGP’s Line A and B pipelines. Rolls-Royce will manufacture and
package the equipment at its energy facilities in Montreal, Quebec, Canada and Mount Vernon, Ohio, USA. Beimbet Shayakhmetov, AGP general
director, said: “The AGP pipeline will help to meet Kazakhstan’s domestic energy needs and to stabilise China’s energy consumption with cleaner natural gas. Rolls-Royce proven technology provides an excellent fit and we are delighted to again cooperate with them to support us in transportation of the gas.” ●
