The engine manufacturer’s local subsidiary in Pakistan, MAN Diesel (pvt.) Limited will be responsible for the supply of local goods and services, the company states.

The Narowal plant is based on 11 of the largest, 18-cylinder, vee configuration versions of the most powerful four-stroke engine in MAN Diesel’s stationary power generation programme, the type 48/60B.

The engines will burn heavy fuel oil (HFO) and will operate in a diesel combined-cycle arrangement.

With a total electrical capacity of over 213 MW, the output of the 11 generator sets based on MAN Diesel type 18V 48/60B engines is complemented by a steam turbine generator driven by steam raised from the engine exhaust gases.

The German company said that the plant is due to go on grid at the end of March 2010. With this commissioning schedule, the Narowal plant will start generation around a year after a 225 MW facility contracted to MAN Diesel in 2007 and already taking shape at Sheikhupura, also near Lahore.

100 MW tri-fuel plant to supply Togo’s national grid

Wärtsilä will supply a 100 MW plant to the Republic of Togo to produce electricity for the national grid.

The power plant will comprise six Wärtsilä 50DF engines designed for tri-fuel capability. The energy supplier ContourGlobal Togo SA awarded the turnkey contract in June.

The power plant will be installed in Lomé, the capital city and is scheduled to be fully operational by the fourth quarter 2009. The engines can run on natural gas, light fuel oil or heavy fuel oil.

The fuel can be switched whilst the engines are operating, eliminating the need to stop the engine. The plant will deliver the same output on all three fuels. This way, the power plant can always use the cheapest and the most readily available fuel.

When operational, the plant will significantly diversify Togo’s power generation portfolio and will supplement the country’s hydroelectric power during the dry season. The electricity investment is the largest in Togo’s history and will double capacity.

Jenbacher gas engines for tropical island’s new waste gas-to-energy plant

GE Energy is providing two of its Jenbacher gas engines for a new 2 MW landfill gas-to-energy plant on the small French island of La Réunion in the Indian Ocean, 680 km east of Madagascar.

The landfill gas project represents an important renewable energy reference site for La Réunion, which is seeking to become completely independent from energy imports by 2025. To reach this goal, the island needs to add an estimated 400 MW in generating capacity from various sources.

France’s “obligation d’achat” feed-in tariff system, which provides incentives for installation of additional renewable energy capacity, helped make the La Réunion landfill gas project more economically feasible for the project’s developer.

By capturing landfill gas instead of emitting it directly into the atmosphere and using it for power generation in place of fossil fuels, the project is expected to ensure the reduction of up to 60 000 tonnes CO2 equivalents per year, thus providing significant environmental benefits.

GE is supplying two of its JMS 320 GS/L.L gas engines for the landfill gas plant being installed near the town of Saint-Pierre, on the southern end of the island. The two Jenbacher units combined will generate more than 2 MW in electrical power, which will then be sold to the local grid.

Meanwhile, the engines’ combined 1172 kW in thermal power (without the use of exhaust gas heat) will create hot water for the landfill’s leachate treatment system, which utilizes a thermal evaporation process in vacuum conditions. The incorporation of heat sources such as engine cooling water, oil and air/fuel gas mixture for thermal power generation ensures the operator additional benefits in terms of better fuel use to reach optimal energy efficiency. Even under challenging tropical climatic conditions, the engines will provide an electrical efficiency of about 40.1 per cent.

“This project is GE’s first landfill gas plant to be installed in any of France’s overseas regions, and we are looking forward to supporting La Réunion’s efforts to create a more sustainable, secure and autonomous energy infrastructure,” said Prady Iyyanki, CEO of GE Energy’s Jenbacher gas engine business.

GE’s authorized Jenbacher gas engine distributor Clarke Energy France is installing the units on behalf of the project developer and investor GRS Valtech, a subsidiary of VEOLIA Environmental Services, in the autumn. GE said that the new Jenbacher units are scheduled to enter commercial operation in November.

To assure the optimal utilization of the landfill gas to generate power and heat, project developer GRS Valtech selected GE’s Jenbacher technology for its reliability, exceptional performance, efficiency and durability, combined with its advanced emissions controls to further reduce the engine’s environmental impact.

Indonesian telecom carrier opts for Atlas Copco generators for standby and prime power

Atlas Copco has completed the delivery of almost 250 generating sets in one of its largest orders for generating sets, to Indonesia’s telecom’s specialist, Indosat.

Forming part of Indosat’s strategy to improve its GSM coverage across Indonesia, the Atlas Copco sets will provide standby and prime power duties for telephone antenna transmitter operation. Primarily located in remote regions where the electricity network is unreliable or insufficient, the sets will ensure continuity of service.

The order featured a mix of Atlas Copco QAX 20, QAX 30, QAS 60 and QAS 250 generating sets. Generally the QAX 20 and QAX 30 sets, rated at 20 kVA and 30 kVA respectively at 50 Hz are providing prime power operation in the more remote locations. Where two sets are installed, each operates 12 hours daily, to ensure continuous operation.

A total of ten QAS 60 and five QAS 250’s provide prime power for the master circuit and control rooms for several antennas where no electrical power is available. The QAS 250s, rated at 250 kVA, are powered by Volvo six-cylinder, turbo-charged and intercooler diesel engines and housed in a soundproof enclosure meeting 70 dB (A) at 7 m.

Indosat was formed in 1967 and by the end of 2006 had become the second largest provider of wireless services in Indonesia with more than 16 million subscribers.

Part owned by the State and Singapore’s Technologies Telemedia, it is Indonesia’s prime carrier of international telecommunications and is the region’s number two cellular operator. The Atlas Copco order valued at €2.8m ($4.4m) was won in an international tender from a preferred suppliers list.

Cummins Power generation aids tea production in Kenya

The Kenya Tea Development Agency (KTDA) provides essential management services to aid the efficient production, processing and marketing of high quality tea, and in turn allow farmers to sell their produce at profitable prices.

It is soon to become the managing agent for 54 tea-processing factories in Kenya, after the completion of the Kapsara factory, which will have a combined annual processing capacity of 75 000 tonnes.

As with many African countries, power outages are frequent and this has a direct impact on the operation of the KTDA’s facilities and the factories that it manage. Therefore the decision was taken to source quotes from companies who could provide adequate standby applications.

As a result of the tender process, the KTDA commissioned its first 512DFGB 640kVA, prime-rated generating set from Cummins Power Generation’s Kenyan distributor, Car and General in late 2006. This soon proved its worth and the KTDA ordered a further 14 units and two C550D5 500kVA, prime rated open sets.

Wilfred Musiko, sales manager for engineering at Car and General, who was key to securing the project, said, “We were able to ensure availability of the sets for timely delivery, installation and commissioning thanks to our inventory planning through blanket orders.

This, coupled with the excellent performance of the generator sets at high altitudes enabled us to provide the ideal solution for KTDA’s need.”

The sets are operating on 50 Hz, 415 V and 3-Phase and because the generators operate on manual changeover it was not necessary for Cummins to supply switchgear. Although the sets are installed for standby operation, the frequent power outages mean the sets run for an average of 50- 60 hours a week per set.

The KTDA received other quotations but decided to go with the Cummins product particularly because of the sets’ ability to perform well at high altitudes (an average of 1800 m above sea level is typical) and Cummins’ evident commitment and ability to meet the tight delivery schedule. In addition, having worked with Car and General previously for many years the KTDA was certain it could rely on the company to deliver the right products, on time and in a professional manner.

Charles Luhanga, procurement manager, of the KTDA, said, “We were impressed by the key performance features of the selected power system, including the engine and the generator reliability.”

“We were also drawn by the excellent customer service we have come to know Car and General for, including the one source warranty and low service costs. Even though we expected it, we were still impressed with the speed of the installation, ensuring our business continues to run efficiently regardless of the regular power outages.”
