MAN Energy Solutions has won an EPC-contract to set up a highly efficient, combined-heat-and-power (CHP) plant for Progressive Energy, the energy arm of the ElcaTex Group in Choloma, Honduras. The plant will be powered by 3 × MAN 18V51/60 engines with an overall capacity of 54.8 MW, generating power and steam for a nearby textile factory.

MAN Energy Solutions will take an EPC (engineering, procurement and construction) role in the project and will be responsible for the construction of the entire plant.

For textile manufacturing, steam is as important as power, which is why Elcatex Group were looking for a solution to efficiently produce electricity as well as steam to drive its manufacturing footprint. Thanks to the new plant, the company will be able to increase its energy efficiency while becoming more autonomous in its steam supply chain.

While the MAN 51/60 engines will operate on heavy fuel oil (HFO) once the new plant opens, Progressive Energy plans to convert them to gas operation as soon as a secure supply of LNG (Liquid Natural Gas, LNG) becomes available. The switch to gas will reduce the plant’s emissions even further.

The engineering and technology group Sener and Acciona Industrial have achieved another relevant milestone initiating the salt melting process at the Kathu Solar Park Concentrated Solar Power (CSP) plant. The molten salt will be used to store heat from the solar field that can later be recovered to produce steam and generate electricity in the absence of solar radiation, extending the operational capacity of the plant after sunset and during cloudy weather.

Thanks to this molten salt storage system, that allows 4.5 hours of thermal energy storage, the Kathu Solar Park CSP Plant will supply clean energy to 179,000 homes. The plant uses SENERtrough®-2 collectors, a parabolic trough technology, specifically designed and patented by SENER, aimed at improving efficiency of the solar field. The significance of this technology – SENERtrough®-2 and molten salt storage system – is that the CSP plant will not only supply power during sunny periods, but as needed to satisfy the peak of demand, without the considerable expense of battery storage.

Siyabonga Mbanjwa, Sener Regional Managing Director in Southern Africa, commented: “The use of molten salt as thermal energy storage system will allow Kathu Solar Park to operate in a cost-effective manner, storing the generated energy from the sun, producing and dispatching electricity, in absence of solar radiation, to satisfy the peak of demand. At Sener, our aim is to provide the most innovative technology, being compliant with Health & Safety stringent standards, to ensure an outstanding performance and thermal stability for a reliable and sustained energy supply.

Roberto Felipe, Chief Operating Officer of Acciona Industrial, said: “This project is technologically cutting-edge, and the complexity of both engineering and construction is only comparable to large infrastructure projects. At ACCIONA, we are committed to the social and economic development of the regions where our projects are located, and the positive impact this plant is having in Kathu and the surrounding areas is a reason for us to continue executing these projects with these high quality standards.

Kathu Solar Park is one of the awarded projects in bid window 3.5 of the Renewable Energy Independent Power Producer Procurement Program (REIPPPP) led by the South African Department of Energy (DOE).

The joint venture between Sener and Acciona Industrial was appointed by the ENGIE led consortium to provide engineering, procurement and construction services for the project. Construction started on site in May 2016 and is due for completion within the next few months. Approximately 1,400 jobs are being created during the construction phase. It is estimated that the Kathu Solar Park will save six million tonnes of CO2 over 20 years and will further promote local economic development through the KSP trust and the Kelebogile Trust, which has invested significantly in the local community thus far thereby making a meaningful contribution to the community of the John Taolo Gaetsewe District Municipality.

Siemens will supply the key components for the Attarat steam power plant in Jordan. The customer China Energy Engineering Group Guangdong Power Engineering Co. Ltd. will build the facility as general contractor for the operator of the plant, the Attarat Power Company. Siemens’ scope of supply comprises two SST5-5000 steam turbines, two air-cooled SGen5-1200A generators, and the turbine control system. The condenser is air cooled to address the lack of water at the site. This can be seen as a global trend for dry areas where water is mainly used for households, farming and ecosystem. The power plant will start operation in mid-2020 and will feed up to 470 MW to Jordan’s power grid.

The Attarat facility will supply enough electricity to cover up to 15 percent of the country’s annual power demand. Jordan is one of the most water-scarce countries in the world. The air cooled condensers will save up to 90 percent of the water needed for the plant’s operation compared with the use of a wet cooling system. Siemens will supply low-pressure turbines which are able to withstand the high back pressure caused by the condensers. The SST5-5000 is the most compact steam turbine generator consisting of one combined high- / intermediate pressure and one low pressure module ever built for a steam power plant. This will provide a small footprint and highest possible performance.

 

Jordan is considered one of the driest countries in the world, and 14 percent of the country’s power capacity is used for water treatment and distribution. The power plant will be built in the desert at Attarat Um Ghudran, 100 kilometers southeast of the Jordanian capital Amman and away from the country’s natural water supplies. The efficient use of scarce resources, especially water, is a critical challenge to provide a reliable power supply for the local population and economy.

In July 2014, the Madrid Health Service announced a public tender for a Mixed-Purpose Contract for Supplies and Works to construct and manage a natural gas-fired thermal plant at the Hospital Universitario La Paz. The 15-year contract had a tender budget of almost €45m (ex. VAT) to supply power to cover the hospital complex’s energy demand for heating, DHW and steam. Four proposals were submitted, with the contract finally being awarded to the joint venture comprising Gas Natural Servicios SDG and Veolia Servicios Lecam.

The Hospital Universitario La Paz is one of the largest hospitals in terms of importance in the Autonomous Community of Madrid and an essential part of the public healthcare system. Consisting of four buildings that house the General Hospital, Maternity Hospital, Children’s Hospital and Trauma Centre, the complex covers a surface area of 180,000 m2 and has a total of 1,328 beds.

 

Due to age (some 50 years) and the degree of wear and tear of its thermal installations, the Hospital Universitario La Paz was facing high energy and O&M costs in addition to: the risk of a lack of supply, with the resultant risk to the health and wellbeing of patients and workers., high environmental impact, due to the use of diesel. and an inability to handle increases in demand.

Two Siemens SST-800 steam turbines are supplying electricity and process steam to a pulp factory in Brazil. The SST-800 has a capacity of 190 MW, making it among the largest steam turbines in use in the pulp and paper industry worldwide. The plant has a total capacity of 270 MW. The customer is Klabin, a leading manufacturer and exporter of paper and packaging.

An extraction backpressure steam turbine and a condensing steam turbine supply electricity and process steam for the pulp factory in Ortigueira, in the southern Brazilian state of Paraná.

The new plant is uniquely flexible, because it has two production lines and can produce two types of fiber simultaneously. The factory has an annual production capacity of 1.5 million metric tons of pulp. 1.1 million metric tons of bleached hardwood pulp (eucalyptus) and 400,000 metric tons of bleached softwood pulp (pine), a portion of which is converted into fluff pulp for products like baby diapers.

Approximately 150 MW of electricity, or more than half of the total of 270 MW produced, is fed into the national power grid. That’s enough to supply electricity to a city of a half-million people.

The most comprehensive gas engine portfolio available in the market and a highly efficient gas and steam turbine range – flexible energy solutions are in the focus of MAN Diesel & Turbo’s 2015 Power-Gen Europe attendance. Europe’s major energy trade fair will take place at Amsterdam Rai in Amsterdam from June 09-11, 2015. “This year’s Power-Gen theme ‘The energy transition is changing…Europe’ could not be closer to the truth”, says Dr. Uwe Lauber, CEO of MAN Diesel & Turbo.

“Today, power plant operators and investors in Europe are confronted with both technical requirements and business cases that are much more complex than a few years ago. Expert advice, in depth consultation and an experienced technology partner are essential to identify the right generation solution for each customer’s individual energy challenge. We welcome PowerGen Europe as another opportunity to showcase the solutions we have to offer and to invite customers, prospects and industry experts alike: Visit our booth and discuss your energy needs with our experts.”

Once again the company puts special focus on the themes of “Natural gas” and “Decentralized power generation” and presents a portfolio of natural gasdriven engines and turbines, added up by a comprehensive portfolio of service solutions, to help and master the European energy transition: “Europe consists of 28 energy markets, each of which has its own, grown energy system and established power generation mix”, says Dr. Hermann Kröger, Senior Vice President and Head of the Business Unit Power Plants at MAN Diesel & Turbo. “All those markets however share a common goal to reduce greenhouse gas emissions and to increase the share of renewable energies. Gas generation is an ideal technology to achieve this: It is low in CO2- emissions and suited perfectly to back up renewables and work towards a low carbon economy.” However the political framework to support the planned transition was not yet fully in place, says Kröger: “If Europe is serious about reducing CO2-emissions, it will need to make those emissions more costly and hence provide a competitive advantage for cleaner forms of energy, e.g. natural gas.”

“There is definitive demand for additional gas generation capacities”, seconds Howard Barnes, Senior Vice President at MAN Diesel & Turbo and Global Head of Power Plant Sales. “We are currently building an 80MW gas fired power plant in Gibraltar featuring our 51/60G gas engine. Our gas engines offer a fuel efficiency of more than 50 percent. They reach full load within minutes, allow fast starts, stops and ramp-ups, all of which are essential capabilities when it comes to integrating large amounts of renewable energy into the system.”

At Power-Gen Europe, MAN Diesel & Turbo introduces its new line of twostage turbocharged gas engines. Both of the company’s gas engine models 35/44G and 51/60G are now also available with two-stage turbochargers. Two-stage turbocharging achieves excellent efficiency thanks to a lowpressure and a high-pressure turbocharger arranged in series. The 35/44G TS and the 51/60G TS are spark ignited two-stage turbocharged gas engines. The 35/44G TS is available in 12V and 20V-cylinder versions with mechanical outputs of 7.4 MW and 12.4 MW. The 51/60G TS can be delivered as an 18-cylinder version with outputs of 18.9 MW and 20.7 MW. While the 18.9 MW aggregate reaches a mechanical efficiency of more than 50%, the 20.7 MW machine is the most powerful gas engine currently available on the market. Also on display at the MAN booth is the company’s MGT gas turbine family, which recently premiered in the Chinese market. “As our youngest member in the range of energy-related turbomachinery, the MGT gas turbine family marks an important step in terms of efficiency and flexibility,” states Dr. Christopher Antes, Senior Vice President and Head of Business Unit Turbomachinery. “Whether it’s highly efficient steam turbines, gas turbines or compressors for processing and transport of natural gas, our comprehensive portfolio of turbomachinery and the related services by MAN PrimeServ supports a whole range of applications in the energy sector”, he adds. This is underlined by the most recent order for four 6.9MW MGT 6200 gas turbines. With 6.9 MW each, they will soon provide electric energy and process steam for Shanghai Volkswagen Automotive Company Ltd. The MGT family offers optimized turbine versions for both energy generation and as mechanical drive. In Combined Heat and Power (CHP) applications, overall efficiencies of up to 90 percent can be reached, which makes the MGT an ideal partner for captive power applications.

Efficiency is also the guiding principle for MAN Diesel & Turbo’s steam turbine portfolio, supporting the sustainable generation of energy. Ranging from 1- 160MW the company offers steam turbines for almost any application, e.g. energy generation from residual heat, Concentrated Solar Power (CSP) or biomass. Also, the company has developed a special expertise for Waste-toEnergy applications and has recently supplied a 50 MW DK 100/400 R steam turbine for the UK-based waste incineration pant „Wilton
