Wärtsilä Corporation, Trade and technical press release, 21 December, 2007
Wärtsilä 34SG gas engines have the benefits of high efficiency, low exhaust emissions, high reliability as well as low maintenance requirements.
Wärtsilä won contracts from the Summit Group of Bangladesh in November 2007 for a trio of new gas-fuelled power plants at Rupganj, Maona and Jangalia in Bangladesh.
For each site, Wärtsilä will deliver four Wärtsilä 20V34SG generating sets with a combined output of 35 MWe, together with related ancillary equipment. Wärtsilä will also provide supervision of the installation work. The 12 sets are required to be fully operational by January 2009 under the terms of the related power purchase agreements with the Bangladeshi Rural Electrification Board (REB). All three plants will be connected to the 33 kV national grid. They will run on natural gas from Bangladeshi gas fields.
The Summit Group owns an IPP (independent power producer), Summit Power Limited, operating a number of power plants supplying electricity to the national grid. The group already has three power plants equipped with a total of nine Wärtsilä 34SG gas-fuelled generating sets: Narsingdi with three Wärtsilä 20V34SG sets, Savar with four Wärtsilä 20V34SG sets, and Comilla with two Wärtsilä 16V34SG sets. Summit is also part owner of the Khulna Barge Mounted Power Plant, operated by Wärtsilä since 1998. This plant comprises two barges with a total of 19 Wärtsilä diesel generating sets having a combined output of 114 MWe.
The three new plants are part of a major long-term programme by the Government of Bangladesh to extend main electricity supplies to the remote areas of the country as part of rural economic development. Although large generating plants are connected to the national grid in Bangladesh, small plants such as the three new plants are also being installed by independent power producers under BOO (build, own and operate) contracts to help meet the rising demand for electricity.
Similar Wärtsilä 34SG-type engines have been chosen for the three new plants as for the previously-delivered plants to allow a degree of standardisation and commonality of spare parts and training. Wärtsilä 34SG gas engines are proving popular for industrial and local power plants in many countries worldwide with local supplies of natural gas. With unit power outputs up to 8.73 MW at 750 rpm, they have the benefits of high efficiency, low exhaust emissions, high reliability and low maintenance requirements. For example, the 20-cylinder Wärtsilä 34SG has a heat rate of 7880 kJ/kWh, equivalent to a brake efficiency of 45.7%. Overall, Wärtsilä 34SG engines are thus cost-effective alternatives to gas turbines.
