Siemens has received an order for the supply of key components for the Bibiyana South combined cycle power plant in Bangladesh. One gas turbine, a steam turbine and a generator are to be installed in the natural-gas-fired single-shaft plant.

The total installed electrical generating capacity of the plant will be around 400 megawatts (MW). The operator of the plant is the state-owned power provider Bangladesh Power Development Board (BPDB). The Bibiyana South plant will be erected by Isolux Corsan, a company specialized in energy, construction, transmission and distribution, with commissioning scheduled for May 2018.

The Siemens SGT5-4000F gas turbine will be installed in the Bibiyana South combined cycle power plant.

The Siemens scope of supply for the plant includes one model SGT5-4000F gas turbine, an SST-3000 steam turbine and a model SGen-2000H generator, along with all associated auxiliary systems and the electrical and I&C systems.

“We are proud to support Bangladesh in its efforts to increase its national power production and pleased that BPDB has put its trust in us. BPDB has once again chosen a general contractor with confidence in efficient Siemens power plant technology,” declared Thomas Hagedorn, head of Sales for the Asia and Pacific region of the Siemens Power and Gas Division.

This marks the eighth project for which Siemens is supplying power plant technology to Bangladesh. Besides the complete drive train for the Bibiyana South combined cycle plant, Siemens is also supplying the key components for the Sirajganj Phase I and II, Ashuganj, Ashuganj South, Ashuganj North, Shikalbaha and Ghorashal power plants. Combined, these eight plants will generate a total capacity of around 2.5 gigawatts (GW) of electricity. Employing its modern and sustainable power plant solutions, Siemens is supporting Bangladesh in the expansion of its national power plant capacity, which now totals around 11.5 GW. Only about 50 percent of the country’s inhabitants have access to electrical energy.

The Bibiyana South project is part of Bangladesh’s major capacity expansion program within the framework of its “Power System Master Plan (PSMP) 2010.” In roughly five years, the country’s population is to enjoy a reliable supply of electricity totaling 24 GW to keep pace with the rapidly growing demand for power in the country. This program is aimed at contributing to social and economic progress in Bangladesh.

GE announced that it has completed the acquisition of Alstom’s power and grid businesses. The completion of the transaction follows the regulatory approval of the deal in over 20 countries and regions including the EU, U.S., China, India, Japan and Brazil. It is GE’s largest-ever industrial acquisition.

GE reached an agreement with Alstom in 2014 to purchase Alstom’s power and grid businesses for €12.35 billion. Adjusting for the joint ventures announced in June 2014 (renewables, grid, and nuclear), changes in the deal structure, price adjustments for remedies, net cash at close, and including the effects of currency, the purchase price is €9.7B (approximately $10.6B). This includes working capital usage of approximately €0.6B in the month of October. GE expects the deal to generate $0.05-0.08 of earnings per share in 2016 and $0.15-0.20 of earnings per share by 2018. GE is targeting $3.0 billion in cost synergies in year five and strong deal returns. The overall economics and strategic rationale remain the same as GE announced in April 2014.

GE also announced today it has completed the sale of its rail signaling business to Alstom for approximately $800 million.

GE continues to execute its strategy to become a simpler, more focused company. In addition to the Alstom acquisition, the split-off of Synchrony Financial has commenced; the GE Capital exit strategy is ahead of plan, with $126 billion of signed dispositions; the recent formation of GE Digital is consolidating all digital capabilities across the company to provide customers with the best industrial solutions and software; and GE is winning in the marketplace and delivering strong financial results.

Duro Felguera (DF), in a 50/50 consortium with Elecnor, has won the tender called by the Comisión Federal de Electricidad (the Federal Electricity Commission or CFE in Spanish) in Mexico to build the Empalme II combined cycle power plant in the State of Sonora. The project is for 397 million dollars, equivalent to 349.3 million Euros. The deadline for delivery is estimated at 30 months.

According to the contract terms, signed at the close of business on Friday 23 October in Mexico City, the capacity of the Empalme II plant will be roughly 790 MW, and it will be gas-fired. There will be two gas turbogenerator units, two heat recovery boilers with three pressure levels and a steam turbine. The cooling system will be simple and will employ seawater. The plant will be connected to a 400 kW substation.

According to CFE, the purpose of the facility is to meet the growing demand for electricity in the north-west of the country.

Mexico is the country where DF has delivered most projects in Latin America, mainly in the field of energy. The power installed is almost 4,500 MW. Since 1998 the company has collaborated in the delivery of combined cycle, open cycle and cogeneration power plants with technologists such as Westinghouse, Siemens and Alstom Power.

DF’s first steps in Mexico in the field of energy were taken in 1998 in projects that the group had contracted by means of its subsidiaries Felguera Montajes y Mantenimiento and Mompresa, for the installation of turbomachinery. Both companies had previous experience in Colombia and started work in Mexico with the electromechanical assembly at the 150MW open cycle power plants of El Sauz, Hermosillo and Huinalá.

These projects were delivered to Westinghouse and followed by the full electromechanical assembly of recovery boilers at the combined cycle plants of Monterrey I, II and III, and Hermosillo, and for the full electromechanical assembly of the Rosarito plant, this time for the multinational ABB Alstom Power, and in larger facilities. In the first decade of the 21st century, the company was contracted by Siemens-Westinghouse to deliver the majority of the work at the open cycle plants of El Sauz II and El Encino: preparing the land, civil works, supplying the balance of plant equipment, the complete electromechanical assembly and commissioning.

These experiences enabled DF to keep on working in the country, with practically the whole assembly of the power plants of Valle de México, Naco Nogales, San Lorenzo and Tuxpan, in some cases almost 350 MW. In addition to the work on all these gas-fired power plants, in 2003 and 2004 the company delivered an EPC turnkey project for a cogeneration plant within the Pemex petrochemical Pajaritos plant, located in Veracruz. In this case DF took on the whole project, from the engineering to commissioning: 39 MW and 180 tons of steam per hour. Almost ten years later, Mompresa built further cogeneration plants in Mexico: one for the paper manufacturer Biopappel in Veracruz, and another for the textile company Kaltex Fibers in Altamira.

Apart from the energy field, DF has also worked on projects on Mexico for the petrochemical, iron and steel, cement and bulk handling sectors, for clients as important as Pemex, Cemex and Altos Hornos de México.
