The propulsion and power solutions specialist Tognum is now expanding its onsite energy business with an order for 40 MTU Onsite Energy power supply generator sets (gensets). The order comes from APR Energy, a global energy solutions provider. Initially APR shall use the gensets to deliver supplementary power for the utility grid in the Trujillo Province in northern Peru, on behalf of the Peruvian Energy Authority.
The gensets are powered by MTU’s Series 4000 diesel engines and are affixed within custom containers, facilitating their use as portable power modules. The scope of supply includes the gensets, as well as the associated switchgear. In addition, Tognum will provide APR with engineering and staff support during the installation phase between April and June 2009.
Trujillo is one of the largest cities in Peru. Power demands have increased significantly in recent years, a surge which has led to occasional shortages within the utility grid. APR’s power solution working with MTU Onsite Energy gensets is designed to offset these shortages, providing an installed power output of 60MW – enough energy to power an estimated 30,000 homes in the United States.
APR Energy – previously named Alstom Power Rentals – has completed numerous short, medium and long term power generation projects, among which fast-track temporary power projects in environments such as Sri Lanka, Mexico and Haiti – i.e., in countries where the infrastructure is not quite as fully developed as for example in Western industrial nations.
Marking a significant step forward in the use of cleaner coal technology to help meet the country’s future energy requirements, the first major pieces of equipment have arrived at Duke Energy’s Integrated Gasification Combined-Cycle (IGCC) plant in Edwardsport, Ind. Using GE IGCC technology, the plant is expected to be the largest cleaner coal IGCC facility of its type in the world when it is complete.
Working from GE Energy’s specifications, Belleli Energy of Italy manufactured a radiant syngas cooler (RSC); the first sections arrived at the site last week. The remaining pieces will arrive later in the year. GE Energy is supplying gasification, power generation and controls equipment and services for the design and startup of the IGCC plant, which will generate approximately 630 megawatts of power when it enters service in 2012.
In an IGCC plant, coal is heated to high temperature to create a synthesis gas or syngas, which is then processed to remove many emissions—NOx, SOx, mercury and particulate matter—before the gas is burned in a specially designed gas turbine to generate electricity. The RSC is under the gasifier and cools the syngas, creating steam, which powers a steam turbine, increasing plant efficiency. Construction of the RSC will take place on-site using mostly local labor and is expected to be completed by the end of 2010.
GE Energy has been at the forefront of IGCC technology for more than two decades. GE technology was involved in several milestone IGCC projects, including the pilot IGCC plant, Coolwater, in Barstow, Calif.; and the Polk Tampa Electric IGCC plant in Florida that helped to demonstrate the commercial feasibility of IGCC. Today, 65 gasification facilities operate under GE gasification licenses, including 33 GE-licensed gasification plants using commercial technology to separate carbon.
Siemens is to continue the expansion of local value creation in growth markets. The company is to expand its steam turbine production in the state of Gujarat for approximately EUR40 million. A new production facility with a surface area of 14,000 square meters is planned. Production capacity for high-efficiency industrial steam turbines will thus triple by 2010. In addition to the Indian market, the turbines will also be exported throughout Asia and Africa, where they will contribute to providing extensive power supply.
Industrial turbines with ratings up to 45 megawatts have to date been produced in Vadodara. The location is part of Siemens manufacturing network for industrial turbines, which is managed from Görlitz. Only recently the company inaugurated a new production facility in Görlitz to be able to better meet the demand for medium-size steam turbines. The additional production capacity in Vadodara will provide the basis for even better serving the markets in Asia and Africa. There are currently still high energy deficits in many emerging countries during peak load periods. However, adequate energy supply is a fundamental prerequisite for moving economic and social development forward in these countries.
High-efficiency industrial steam turbines are an important feature of Siemens environmental portfolio, with which the company posted revenue totaling almost EUR19 billion in fiscal 2008. That is equivalent to around a quarter of the company’s total revenue and makes Siemens the world’s leading green infrastructure provider. Industrial steam turbines are deployed above all in cogeneration plants, combined heat and power plants, and small combined cycle plants, which are among the most efficient forms of power and heat generation. Small and medium-size steam turbines are also deployed, for example, in sugar and pulp mills or in the chemical industry to make even better use of process steam.
 To help meet growing energy and environmental needs in the Iberian region, DETISA, an energy supplier owned by major Spanish oil company CEPSA, has selected GE Energy’s gas turbine technology for a new cogeneration project in San Roque, Cádiz, Spain.
GE will supply a Frame 6B gas turbine-generator for the Lubrisur Cogeneration Plant, which will help to meet the increasing energy requirements of the Gibraltar-San Roque refinery, with excess electricity to be sold to the Spanish grid. The plant has a capacity of 42 megawatts of power and also will produce steam to be used for refinery processes.
Burning natural gas, the Frame 6B gas turbine will employ a dry low NOx system that will meet the region’s strict environmental regulations.
Cogeneration is a growing trend in Spain, where the government is pushing for energy savings, reduced grid losses and reduced greenhouse emissions to meet the standards of the Kyoto Protocol on Climate Change.
The GE Frame 6B is one of the most versatile and widely used gas turbines ever manufactured. More than 1,100 of these units are in service or on order worldwide and have accumulated more than 60 million operating hours. Close to 30% of all 6Bs in operation are being used for cogeneration, located in countries on six continents.
Commercial operation of the Lubrisur project is scheduled to begin by the end of 2010.
MAN Diesel, in collaboration with wind turbine manufacturer Enercon and planning and consulting firm Econcern, is building the world’s largest wind/ diesel hybrid power plant on the Caribbean island of Bonaire. The plant comprises a wind park with twelve wind turbines and a (bio-)diesel power plant that will produce electrical power with five MAN diesel engines of type 9L27/38. The hybrid power plant will function as an independent base load power plant from the end of 2009 onwards, supplying the entire island with a total of 25 MW of eco-friendly energy. The value of the order for MAN Diesel is over Euro 15 million. The customer is Water en Energie Bedrijf Bonaire (WEB), the state-run energy provider in the Dutch Antilles.
The wind park will be the primary source of electricity generation. During calm periods, tropical storms or peaks in demand, the engines in the diesel power plant will also kick in quickly to ensure a constant and reliable supply of power to the population. Compared to conventional power plants, such as the large steam turbine systems used to generate electricity, MAN Diesel engines have the advantage that they require only a very short start-up time and therefore are available virtually at the press of a button. This flexibility makes them the ideal assembly for wind hybrid power plants. Intelligent control electronics ensure that the MAN Diesel power plant is able to even out the inconstant electricity generation from wind energy and the fluctuations in demand. The extremely high efficiency of diesel engines also ensures the maximum possible yield from the fuel used. These – according to the plans – will be switched over within the next three years entirely to bio-diesel, which is to be obtained from seaweed. The wind/diesel hybrid power plant will then sustainably provide the entire island with CO2-neutral electricity and thus save around 70,000 tonnes of the greenhouse gas a year compared to the current power plant, which runs on fossil fuels.
The specialist for propulsion and power solutions Tognum has recently been awarded a strategically important onsite energy contract by international construction firm Orascom Construction Industries. Tognum is to furnish a new airport tower at Cairo International Airport – the airport with the second highest passenger numbers on the African continent – with two emergency power supply gensets.
These MTU Onsite Energy gensets are designed to supply the new tower, which is scheduled to start operating in June, with emergency power whenever outages occur.
The emergency power supply gensets equipped with 12V 4000 G63 engines deliver a total of 4,000 kVA electrical power. Should the power supply in the tower fail, the MTU Onsite Energy gensets ensure air traffic control continues as required.
Strict regulations apply to the technical requirements imposed on the operation of gensets for airport control towers. These affect, in particular, the stability of both voltage and frequency when activating a variety of consumer units, e.g. elevators, lighting or IT systems. Also, sound insulation is used in the intake and exhaust air areas in order to keep well below the maximum permitted noise emission limits.
The power unit commissioned by Energotechmontazh, MPNU designed on the base of C-30 microturbine by Capstone Turbine Corporation was put in operation at the beginning of the year as part of the power complex at the industrial site.
In addition to gas turbine power unit the power complex is equipped with GFL-200 Vacotin Heater vacuum boiler by Takuma Boiler Company (Japan) with the capacity of 300 kW and 500 kW NPR-500 hot-water boiler manufactured by Garioni Naval (Italy).
