Cattle waste-biogas congeneration project wins ‘Best green power plant’
India Infoline News Service / Mumbai Sep 11, 2007

"A demonstration cattle waste-biogas cogeneration project in Punjab,
India, powered by GE Energy Jenbacher gas engine, has been chosen as the
‘Best green power plant’ in Asia at the 2007 Asian Power Awards. In
order to reduce the dairy complex’s greenhouse gas emissions and to
prevent the improper disposal of the animal wastes, the Punjab Energy
Development Agency (PEDA) had installed and commissioned this
demonstration power generation facility in 2004.

Since late 2004, GE Energy's 1-MW Jenbacher biogas cogeneration system
has supported the model cattle waste-to-energy conversion plant at the
Haebowal dairy complex in the city of Ludhiana, in Punjab. The complex
serves 1,490 dairy operations that own 150,000 head of cattle,
generating a total of 2,500 tons of waste daily. GE's Jenbacher
demonstration plant uses the biogas with high methane content to
generate electricity and thermal power (hot water).

Surplus energy remaining after meeting the plant auxiliary requirements
from the engine is sold to the local grid of Punjab State Electricity
Board (PSEB), while water heated by the engine is used to assist the
digester fermentation process. In addition to the plant’s energy and
thermal output, remnants of the digester process are used as fertilizer
by local farmers."
