Oak Ridge National Laboratory Debuts Titan Supercomputer
The Energy Department's Oak Ridge National
Laboratory (ORNL) on October 29 debuted the Titan supercomputer, a
system capable of a theoretical peak performance exceeding 20 trillion
calculations per second (or 20 petaflops). Titan employs a family of
processors called graphic processing units (GPU), first created for
computer gaming, and will be 10 times more powerful than ORNL's last
world-leading system, Jaguar.
Titan will provide unprecedented computing power
for research in energy, climate change, efficient engines, materials,
and other disciplines and will pave the way for a wide range of
achievements in science and technology. Titan utilizes a Cray XK7 system
contains 18,688 nodes, each holding a 16-core AMD Opteron 6274
processor and an NVIDIA Tesla K20 GPU accelerator. Titan also has more
than 700 terabytes of memory. The combination of central processing
units, the traditional foundation of high-performance computers, and
more recent GPUs will allow Titan to occupy the same space as its Jaguar
predecessor while using only marginally more electricity. See the ORNL press release.
USDA Announces $3 Million in Smart Grid Funding
The U.S. Department of Agriculture on October 19
announced $107.5 million in loan guarantees to modernize and improve
rural electric systems, including nearly $3 million in Smart Grid
technologies in North Dakota and Wisconsin.
According to a 2009 Energy Department report
that examined Smart Grid deployment nationwide, Smart Grids have the
potential to dramatically change how we manage electricity use in the
United States. In August, the USDA reported that it had met its goal to
finance $250 million in Smart Grid technologies in fiscal year 2012. See
the USDA press release.
Navy's China Lake Solar Plant Begins Operations
SunPower Corp. on October 19 announced the
completion of the U.S. Navy's largest solar system, a 13.78-megawatt
solar photovoltaic (PV) power system at Naval Air Weapons Station China
Lake, California. The power plant is the first federal agency project to
be financed through a 20-year term solar power purchase agreement. The
plant, designed and operated by SunPower Corp., is generating the
equivalent of more than 30% of China Lake's annual energy load, helping
to reduce costs by an estimated $13 million over the next 20 years.
The 20-year power purchase agreement requires no
upfront capital or maintenance obligations from the Navy, matches
conventional project financing terms for solar power facilities, and
allows the Navy to secure electricity at up to 30% below the rate
available through shorter duration 10-year power purchase agreements.
SunPower has installed more than 50 megawatts
(MW) of solar power systems at government facilities to date. The
systems the company has delivered to the Navy and U.S. Air Force alone
generate enough electricity to power about 9,000 homes. According to
U.S. Environmental Protection Agency estimates, the Navy and Air Force
systems will reduce the amount of carbon dioxide emitted into the
atmosphere by almost 732,000 tons over the next 20 years. See the SunPower press release.
China Lake also has four geothermal power plants
that produce up to 270 MW of electricity, or enough electricity for
approximiately 378,000 households. The site has been in continuous
operation since 1987, and was the Navy's first site to tap thermal
energy. See the China Lake Natural Resources webpage.
Interior Announces Lease for Delaware Offshore Wind
The U.S. Department of the Interior (DOI) and
its Bureau of Ocean Energy Management (BOEM) announced on October 23
that BOEM has reached an agreement on the first commercial lease under
its "Smart from the Start" initiative for offshore wind energy
development. Situated in federal waters, the site covers 96,430 acres
approximately 11 nautical miles off the coast of Delaware.
The lease grants NRG Bluewater Wind Delaware LLC
the exclusive right to submit one or more plans to BOEM to conduct
activities in support of wind energy development in the lease area. The
company may submit a Site Assessment Plan with a proposal to conduct
site assessment activities, such as the installation of a meteorological
tower or meteorological buoy. It can also submit a Construction and
Operations Plan to propose construction of the actual wind facility and
cabling to shore.
NRG Bluewater originally proposed a 450-megawatt
project off the coast of Delaware, with estimates that the project
could generate enough power to supply electricity for more than 100,000
homes. This estimate could change after NRG undergoes additional
planning and survey work and submits its plan to BOEM, which will assess
the potential plans based on environmental, technical, and other
factors before granting approval for construction. The Smart from the
Start initiative for the Atlantic Outer Continental Shelf, announced in
2010, is designed to facilitate siting, leasing, and construction of new
offshore renewable projects. See the DOI press release and the BOEM Delaware webpage, which includes a map of the site.

INCITE Program Doles Out Hours on Supercomputers
What's one recipe for accelerating scientific discovery and innovation?
Start by taking a couple of world-class
supercomputers, including Titan, which just debuted as the world's most
powerful machine for open science. Provide serious processing hours to
dozens of brilliant people working on the toughest problems they can
find. Plug the programs in and let them cook. When they're done, the
result is simulations that astonish the mind, and more importantly,
solutions that increase America's competitiveness and may lead to
significant scientific advances.
In a sense, that's the recipe for success of the
INCITE (Innovative and Novel Computational Impact on Theory and
Experiment) program. Since the program made its first awards in 2004, it
has provided more than 10 billion processing hours on the Energy
Department's fastest supercomputers to scientists across the globe
taking on the field’s most difficult challenges. For the complete story,
see the Energy Blog.
