PITTSBURGH -- January 17, 2013

Emerson Process Management, a global business of Emerson (NYSE: EMR), has been
awarded a contract to apply its Ovation™ expert control system at the Crescent
Dunes Solar Energy Project near Tonopah, Nev. When it comes online at the end
of 2013, this 110-megawatt concentrated solar power (CSP) project will be the
first commercial-scale solar facility in the United States to generate power
from solar energy that is captured and stored in liquid molten salt.

The project, which is being developed by Tonopah Solar Energy LLC, an
affiliate of SolarReserve LLC, is expected to produce enough clean, renewable
electricity to power more than 75,000 homes during peak electricity demand,
and will be executed by Cobra Thermosolar Plants, Inc. as engineering,
procurement and construction contractor.

The Crescent Dunes facility will use SolarReserve’s CSP technology, which
enables energy from the sun to be captured and stored to generate electricity
on demand – not only when the sun is shining – thereby contributing to overall
grid stability. The facility’s 10,500 mirror assemblies focus the sun’s energy
to heat molten salt that flows through a central receiver, which sits atop a
540-foot-tall solar power tower. The molten salt will flow from the “cold”
storage tank, up the tower where it circulates through the receiver and is
heated by the sun’s energy from 500 degrees Fahrenheit to 1050 degrees. The
molten salt then flows down to the “hot” storage tank, where the thermal
energy will be used to produce steam to power a standard steam turbine, which
then generates electricity. Excess thermal energy will be stored in the molten

Emerson’s Ovation technology will directly control the circuit and heating
process of the molten salt system, the water/steam cycle and auxiliary
processes. The control system will also provide supervisory control of the
mirrors and interface with the turbine control system.

An important consideration in the selection of Emerson was the robust
diagnostic capabilities offered by its AMS Suite predictive maintenance
software. AMS Suite will provide online access to instrument and valve
diagnostics and automatic documentation of field device maintenance
information – all contributing to ongoing efficiency at the solar plant. It
will also be used to streamline device configuration and commissioning.

“This is a truly innovative project that will be an important source of clean,
reliable electricity,” said Bob Yeager, president of Emerson Process
Management’s Power & Water Solutions. “By providing integrated control of
major equipment and processes, our Ovation system and the predictive
intelligence of AMS Suite will play a key role in the smooth, efficient
operation of this noteworthy solar project.”

The contract was awarded by Cobra Thermosolar Plants Inc.
