rarily stop the purchase of power from cogeneration SPPs from 31 August 2007.
At the end of 2007, 16 cogeneration facilities under SPP program were selected
with total generating capacity of 1,663 MW and total sale of electricity into the
grid of 1,314 MW (Amranand 2008). This reflected the policy loopholes, which
allowed more cogeneration power projects using conventional fossil fuel, mainly
natural gas, instead of increasing the use of renewable fuels. This was repeated in
2008 when the electricity coming from conventional fuel amounted to 1,670 MW,
or 73% of total SPP sold into the grid. 382 MW or 17% of the electricity sold to
the grid came from renewable resources, mainly from bagasse and paddy husk;
another 10% came from combined mixture of bio-resources and conventional fos-
sil resources (

As of June 2008, 441 very small power plants (VSPPs) had submitted applications
to sell 1,853 MW of electricity into the grid. Among these, 434 projects are re-
newable energy with total sale into the grid of 1,819 MW (93% of total new VSPP
projects) while the other 7 projects are cogeneration projects (Amranand 2008).
