NORTH AMERICA Vaisala Puts Due
to Work for Rush
Creek Wind Farm
Vaisala in September said it provided due diligence services to Xcel
Energy for the 600-M W Rush Creek
“As Colorado aims to source
almost a third of its electricity from
renewable sources by 2020, Rush
Creek represents a major step forward toward meeting that goal,”
Matthew Hendrickson, Vaisala’s
global manager of energy assessment, said.
Vaisala provided detailed analysis of meteorological observations
at the project sites, weather simulation, expected energy production
and uncertainties surrounding generation predictions for the project.
The purpose of Vaisala’s reports
was to characterize expected generation at the Rush Creek site,
and in the process create investor certainty for Xcel Energy. Vaisala said that the Rush Creek Wind
Farm I site is expected to produce
just over 2,311 GWh on an annual
basis, enough to power more than
200,000 homes. This total accounts
for the real-world effects that can
cause wind farm energy losses,
including availability issues, wake
effects, line losses and turbine inef-ficiencies and degradation. ￮
Lockheed Martin Opens
Advanced Bioenergy Plant
Lockheed Martin in September opened a new bioenergy facility
in Owego, New York.
The system uses Concord Blue’s advanced technology to
convert waste into clean energy.
“This new bioenergy technology can change the way our
world addresses clean energy and waste management chal-
lenges,” Frank Armijo, vice president of Lockheed Martin Ener-
gy, said. “At our bioenergy facility in Owego, we’re able to reduce
our own energy costs while also demonstrating the ground-
breaking capability of our technology to potential users.”
According to Lockheed Martin, the self-sustaining system
can transform waste into electricity through a process called
advanced gasification. There are four key steps in the process:
• Waste Collection: The Owego facility will initially use
wood-waste, with plans to transition to municipal, commercial or industrial waste to create its power in the
• Waste Conditioning: Metal, glass and other materials are
removed, and the waste is dried to specification.
• Gas Creation: Proprietary heat carrier spheres are heated
and mixed in with the organic waste. Once a certain temperature is reached, the solid waste turns into gas, which
then travels to a reforming vessel where the gas is turned
into synthesis gas (syngas).
• Power Generation: The syngas is then used to fuel a combustion engine that produces electricity. Alternatively, the
syngas can be used to produce hydrogen and biofuels.
Unlike incineration, the process is oxygen-free and flame-
free, which means no harmful byproducts are produced, emis-
sions are limited and waste going to landfills is greatly reduced.
Lockheed Martin and Concord Blue also recently started
construction on a bioenergy plant in Herten, Germany. The
facility will convert 50,000 tons of feedstock per year into 5
MW of energy output. ￮
