72 International Mining | SEPTEMBER 2016
Scheduled for completion in 48 months, the plant
will support the phosphate mining operations in
the locality, in turn driving industrialisation and
job creation.
GE will deliver the turnkey power plant, supplying
four advanced GE 7F.05 heavy duty gas turbines
and a GE steam turbine, and featuring solar
innovation technology. One of the gas turbines
will be assembled fully at the GE Manufacturing
Technology Centre in Dammam, underlining GE’s
commitment to localisation. The remaining gas
turbines will be produced at GE’s manufacturing
plant in Greenville, South Carolina, USA, and the
steam turbine will be produced at GE’s
manufacturing plant in Schenectady, New York.
GE’s 7F.05 heavy duty gas turbine technology
brings industry-leading flexibility to the Waad Al
Shamal plant with a 10 minute startup to an 80%
load. It can accommodate a wide range of fuels
lending greater flexibility to the operations while
providing customers with lower fuel costs
compared to previous GE technology. GE Power
will also extend its long-term service support to
the plant to ensure seamless operations.
Caterpillar recently launched of Cat® Microgrid
technology, "an innovative suite of power
systems that adds environmentally friendly solar
panels, state-of-the-art energy storage, and
advanced monitoring and control systems to
Caterpillar’s traditional line of reliable power
generation equipment, including Cat generator
sets, switchgear, uninterruptible power supplies
and automatic transfer switches."
Described as ideal for a broad range of
applications including mining installations, the
Cat Microgrid technology suite is designed to
reduce fuel expenses, lower utility bills, decrease
emissions, and reduce the total cost of
ownership while increasing energy efficiency in
even the most challenging environments.
Available worldwide through the Cat dealer
network, Cat Microgrid technologies can be
purchased as turnkey installations or design-toorder solutions. Ranging from 10 kW to 100 MW,
units can be added in a modular fashion to create
systems customised for a variety of power needs.
Caterpillar says it has proven the real-world
value of its microgrid technology by
commissioning a system at its Tucson Proving
Ground in Arizona. In March 2016, facility
managers installed 500 kW of photovoltaic solar
power along with 500 kW of short-term energy
storage in the form of batteries and
ultracapacitors to supplement power that
previously had been supplied solely by three C15
410 kW diesel generator sets. The integrated
system is expected to reduce fuel consumption
by approximately 33%.
“With the declining cost of renewable energy
sources and rapid advances in energy storage
technology, the time is right to provide an
