It offers a spaceminutes. conscious design with a 24 m x 6.5 m footprint, The high power density and reliability of these and can be shipped by land, air, or sea to units allows APR Energy to deliver scalable anywhere in the world for quick installation. solutions of 400 MW or more that can integrate A key advantage of turbines over reciprocating into existing infrastructure and operate on a technology is the fuel flexibility they bring. The semi-permanent basis. TM2500+ has the ability to operate on, and switch seamlessly between, diesel and liquid distillate fuels. It is also dual frequency, with the ability to easily convert from 50 to 60 Hz.

At the beginning of the year, GE was NORDIC CENTAURUS awarded a landmark LED N4601 QD contract valued at 7200lm Operational nearly $1 billion for the Quake Dampening engineering, Heavy Duty Construction construction and provision of gas turbine services for the Waad Al Shamal 1,390 MW combined cycle power plant of Saudi Electricity Co (SEC). 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
