The Combined Heat and Power plant at the International Tech Park Bangalore, India constructed, operated and maintained by Wärtsilä, has been awarded the Best Decentralised Power Plant in Asia for 2007 by Asian Power Awards at a ceremony held in Bangkok, Thailand. The Asian Power Awards serve to recognise the industry players in Asia whose efforts have stood out over the past year.
The plant has 4 Wärtsilä engines generating 16.40 MW of continuous power for more than 130 companies employing over 20,000 employees within an area of over 2.3 million sq ft.
The International Tech Park Bangalore (ITPB) was built in three phases. The total peak power demand for the three phases has been estimated to be about 9 MW, 21 MW and 24 MW respectively. To cater to the essential loads of the park for Phase I, a diesel captive power plant (CPP) comprising three Wärtsilä diesel generating (DG) sets with an output of 3 MW each was selected.
The CPP generates power at 11 kV and is connected to 11 kV systems of the park, which in turn is fed by a 220/11 kV transformer. An additional DG set of 3.4 MW was installed in 2004 which was further augmented recently with a 7.4 MW Wärtsilä DG set in 2006 to feed the new 6th building in the complex. It was during the planning stages that the concept of heat recovery & chilling was developed along with Ascendas’s consultants Tata Consultancy where all four existing DG sets were to be provided with an exhaust waste heat recovery system along with a heat recovery system on the new 7.4 MW DG set. The heat was also recovered from the new 7.4 MW DG’s HT water cooling system. Since the IT Park has a fully air conditioned facility the heat recovery was primarily designed to generate chilled water using Vapour Absorption Machines which use harmless Lithium Bromide solution as an absorbent and non-toxic lithium molibidate and lithium nitrate inhibitors and water as refrigerants. As there is no usage of CFC (Chloroflourocarbon), the VAM machines are also ozone-friendly. Wärtsilä was selected as the main vendor to install the DG sets, heat recovery systems and VAM machines.
The Award is conferred after intense deliberations by a panel of experts - comprising C.V.J. Varma, the President & CEO of the Council of Power Utilities, Edward K.M. Chen, Chairman of Taiwan Power Company, John Goss of Ceejay International, Lee Jang-Pyo, General Manager of International Relations Department, KEPCO, Tim Charlton, the publisher and editor-in-chief of Asian Power magazine and the AESIEAP Goldbook and Rowena Everson, Group Editor of Charlton Media Group, and involved the solicitation of nominations from the industry.
