26 March 2012
GE’s Jenbacher Cogeneration Technology Set to Power Urban District Energy Project in Melbourne
 

  • 2-Megawatt (MW) Jenbacher Unit to Help Cogent Energy Supply Power, Heat and Cooling for Dandenong Commercial District
  • Cogeneration Plant Could be Expanded Up to 6 MW to Meet Melbourne’s Growing Energy Needs

MELBOURNE, AUSTRALIA—March 26, 2012—One of GE’s (NYSE: GE) natural gas-fired Jenbacher gas engines will be powering a cogeneration plant that will provide reliable electricity and thermal energy for a major urban revitalization initiative in Dandenong, Victoria. Built by Cogent Energy, the plant will play a pivotal role in the VicUrban-lead Revitalising Central Dandenong (RCD) initiative that is rejuvenating the south-east region of Melbourne.
The collaboration marks GE’s first urban district energy project in Australia.Clarke Energy Australia, GE’s authorized distributor for Jenbacher gas engines in Australia, will supply project owner Cogent Energy with a 2-MW,J612 Jenbacher cogeneration unit for Phase 1 of the new power facility, which could be expanded to 6 MW.
GE’s ecomagination-qualified Jenbacher system was shipped to the Dandenong site in January, with commercial operation set to begin this year. The gas engine is expected to save the equivalent of about 9,900 tons of carbon emissions a year, which equals the removal of more than 5,500 cars from the road.
The cogeneration plant is set to dramatically reduce the emissions and energy use of the Dandedong Commercial District by reducing its reliance on energy from the grid. The plant also will have the capacity to produce surplus hot water, which Cogent Energy will then sell back to local commercial buildings to provide cooling via building owner-supplied absorption chillers.
“Helping central Dandenong transform itself into a vibrant, 21st century retail and services district will require a reliable, cleaner, cost-effective supply of energy to meet the growing needs of the area’s business and residential communities,” said Blair Healy, manager of Cogent Energy. “GE’s Jenbacher technology offers the optimal energy efficiency we required to make this project successful.”
“Australia represents an important growth region for GE as more customers embrace various distributed power applications—including industrial cogeneration—to bring the sources of energy production closer to end-users,” said Rafael Santana, CEO and president—Gas Engines for GE Energy.
GE is helping customers worldwide to generate reliable on-site electricity and heat at or near the point of use through its comprehensive suite of distributed power solutions ranging in size from 119 kilowatts to 100 MW. The fuel flexibility of GE’s Jenbacher gas engines and its other distributed energy technologies also promotes greater regional energy and economic security by enabling countries to use more of their own energy resources to meet their domestic needs.
The Dandenong project builds on GE’s commitment to supporting Australia’s energy goals. The company’s involvement in Australia dates back to 1902 when GE installed one of the electric motors in Sydney to open the Pyrmont Bridge over Darling Harbour.
More recently, in September 2011, GE announced it would supply an integrated solution of on-site power and water filtration equipment to a consortium that is building a water treatment plant on behalf of Australian coal seam gas company QGC. The project, located at QGC’s Kenya site near Chinchilla in Queensland, integrates GE’s Jenbacher and Waukesha gas engines for the first time. The units will generate on-site power for GE’s advanced membrane and thermal water treatment technologies that will desalinate water produced during the extraction of coal seam gas.
GE’s Jenbacher gas engines are designed to run soley on a variety of gases, which results in high levels of generator efficiency, reliability and environmental performance.
Many of GE’s Jenbacher products are ecomagination-qualified, providing customers with products that improve their operating performance and reduce environmental impact. Ecomagination is GE’s business strategy to help meet customers’ demand for products that improve their bottom line and reduce their impact on the environment. Ecomagination reflects GE’s commitment to invest in a future that creates innovative solutions to environmental challenges.

Dominion Virginia Power Offshore Wind Study Recommends Ocean Substations Be Added in Atlantic

Mar 13, 2012
RICHMOND, Va., March 13, 2012 /PRNewswire/ -- One offshore substation platform with two 230,000-volt power lines is appropriate to transmit to shore every 500-700 megawatts of wind-generated electricity constructed off the coast of Virginia, a study done at Dominion Virginia Power's request recommends.
The report, completed by ABB Power Systems Consulting, evaluated the offshore transmission options to support future projects and built its recommendations on the company's first study in 2010 that looked at potential on-shore interconnection options and upgrades needed to support offshore wind generation projects. The studies complement one another as transmission lines from the four recommended offshore service platforms would likely be routed to two separate onshore interconnection points.
The report acknowledges the potential cost savings that may be achieved through construction of offshore transmission infrastructure completed in stages with a potential for standardization. The approach also limits the potential for stranded transmission investment as offshore wind farms are constructed.
The report estimated the cost for each offshore service platform, its equipment and submarine transmission cables at approximately $652 million.
"As public policy is developed to support wind farms off Virginia's coast and leases are issued, Dominion will continue evaluating transmission options to ensure the identification of the lowest cost alternative for bringing offshore wind electricity to customers," said Scot Hathaway, vice president-Electric Transmission.  "It is important that we continue to understand these costs and work to reduce them as we consider the possibility of offshore wind generation."
Dominion is planning to respond to the federal Bureau of Ocean Energy Management's call for information for wind generation in about 113,000 acres of leasing areas approximately 24 miles off the Virginia coast. The leasing area is divided into 19 whole blocks, each 3-by-3 miles, and 13 partial ones.
Dominion has a $500,000 grant from the U.S. Department of Energy to work with partners and find ways to reduce the costs of offshore wind generation. The DOE estimates that offshore wind generation alone would cost about 24 cents per kilowatt-hour; Dominion's residential rates today for generation, transmission and distribution services are about 11 cents per kilowatt-hour.
Dominion is one of the nation's largest producers and transporters of energy, with a portfolio of approximately 28,000 megawatts of generation, 11,000 miles of natural gas transmission, gathering and storage pipeline and 6,300 miles of electric transmission lines. Dominion operates the nation's largest natural gas storage system with 947 billion cubic feet of storage capacity and serves retail energy customers in 15 states.

AEP Increases Natural Gas-Fired Generation Capacity

Following is another news release indicating increased use of natural gas.  As explained previously, natural gas is not a renewable energy source; however, because it produces the least greenhouse gases (GHGs) of the fossil fuels, it is worth paying attention to.  This news release is from an electric utility, American Electric Power.


AEP Increases Natural Gas-Fired Generation Capacity As Newly Constructed Dresden Plant Goes On Line
COLUMBUS, Ohio, Feb. 1, 2012 – American Electric Power (NYSE: AEP) has begun commercial operation of the Dresden natural gas-fired power plant, a nominal 580-megawatt combined-cycle generating unit. The plant, located near Dresden, Ohio, provides 25 permanent jobs and employed more than 800 workers at the peak of construction.
With the start-up of the Dresden plant, AEP has added more than 4,800 megawatts of natural gas-fired capacity to its generating fleet in the past decade. Natural gas accounts for 24 percent of AEP’s total generating capacity.
 “This is another step in the transformation of AEP’s generating fleet as we continue to diversify our fuel mix to improve our environmental footprint and provide economical electricity for our customers,” said Nicholas K. Akins, AEP’s president and chief executive officer. “Natural gas will become an increasing part of AEP’s generating portfolio in the coming decades as a result of the development of shale gas reserves and new environmental regulations, but we continue to believe our company and our nation need a diverse electricity generating portfolio that also includes investment in cleaner coal technologies, nuclear and renewable power.”
AEP purchased the partially constructed Dresden plant in 2007 for approximately $85 million from Dresden Energy LLC, a subsidiary of Dominion. AEP accelerated construction of Dresden in January 2011. Total costs for the plant were approximately $366 million.
The Dresden plant will supply electricity to AEP’s Appalachian Power customers in West Virginia, Virginia and Tennessee.
