MINISTER OF THE STATE OF THE MINISTRY OF NEW AND RENEWABLE ENERGY (SHRI VILAS MUTTEMWAR)
(a), (b),(c),(d)&(e) : A Statement is laid on the Table of the House.
Statement
Statement referred to in reply to parts (a), (b),(c),(d)&(e) of the Lok Sabha Starred
Question No. 272 for 31.08.2007 regarding Setting up of Non-Conventional Energy Power
Projects
(a): No, Sir.
(b): 10,467 MW grid-interactive renewable power generation capacity has been
set up in the country as on 30.06.2007, comprising 7231MW from wind power, 2013MW
from small hydro power, 1221 MW from bio-power and 2 MW from solar power, making
the country one of the leading players in the sector, especially in relation to
exploitation of estimated potential, details of which are given in Annexure.
In the case of wind power and small hydropower deployment, the country is placed
respectively at fourth and tenth positions globally. In bagasse-cogeneration
deployment the country is the leader. However, grid-interactive solar power,
whose unit cost of generation is estimated at around Rs.20/kWh, is yet to attain
economic viability in the existing conditions.
(c),(d) &(e) : Proposals from state governments as well from private sector for
the grant of central financial assistance under the schemes / programmes of the
Ministry are received on a regular basis. At times, these proposals are found to
be incomplete or not in line with the provisions of the schemes / programmes.
Complete proposals are considered and approved subject to budget provisions.

Annexure referred to in reply to Part (b) of the Lok Sabha Starred Question No.272
for 31.8.2007
Details of estimated potential and deployment of Grid Interactive Renewable Power

MW= Megawatt
Note:-
(1): Potential based on areas having wind power density (wpd) greater than 200 W/m2
assuming land availability in potential areas @ 1 per cent and requirement of wind farms
@ 12 ha/MW, not all of which may be technically feasible and economically viable for
grid-interactive wind power. In line with international practice for setting up grid-
interactive wind power systems on sites with wpd greater than 300 W/m2,potential is
estimated at 5000MW. Even if sites with wpd greater than 250 W/m2 were to be considered,
potential is estimated at 15000 MW. Further, preliminary surveys do not at this juncture
suggest a sizeable grid interactive offshore wind power potential. In comparison, wind
power potential of USA considering sites having wpd greater than 300 W/m2 is estimated
at 2.0- 7.6 million MW assuming PLF @ 25 per cent, depending on severity of land use
restrictions. Deployment in the USA is placed at 12,736 MW corresponding to potential
exploitation level of 0.17 - 0.64 per cent. in Europe, potential exploittation level
for sites having wpd greater than 300 W/m2 is estimated at around 1-3 per cent,
depending on serverity of land userestrictions. As against these, potential exploitation level
of 16 per cent has been attained in the country, notwithstanding the lower wpd of 200 W/m2,
thereby placing it in 4th position globally.
(2): Technically feasible and economically viable hydro potential is generally
accepted at 40% of the total estimated potential. Accordingly, the technically
feasible and economically viable small hydropower potential could be around 6000MW
of which over 2000 MW has already been harnessed, placing the country in 10th position
globally.
(3): Although the potential is based on surplus agro-residues, in practice there
are several barriers in collection and transportation of such agro-residues to the
generation site and biomass power generation units prefer to use fuel-wood for techno-
economic reasons. A potential of 45,000 MWe from around 20mha of wastelands assumed
to be yielding 10MT/ha/annum of woody biomass having 4000 k-cal/kg with system
efficiency of 30% and 75% PLF has not been taken into account.
In order to realize this potential a major inter-Ministerial initiative involving,
among others, Environment & Forests, Agriculture, Rural Development, and Panchayati
Raj would be required. Further, a Biomass Atlas is under preparation which is expected
to more accurately assess state-wise renewable energy potential from agro-residues.
(4): With the establishment of new sugar mills and modernization of existing ones,
technically feasible potential is assessed at 5000 MWe, not all of which may be
economically viable. Furthermore, several sugar companies/cooperatives are unable to
develop bankable projects on account of their financial and liquidity positions.
Even then, the country is leading in bagasse cogeneration deployment.
(5):With expansion of urban population post census 2001, current technically
feasible municipal waste-to-energy potential is assessed at 1700 MWe, not all of
which may be economically viable. However, subsidy disbursement under the municipal
waste to energy programme had been kept in abeyance on the orders of the Supreme Court
in the case of a PIL, in May 2005. This stay has now been vacated for setting up 5
pilot projects.
(6): Not all of this renewable energy potential may be suitable for grid-interactive
power for technical and / or economic reasons. Further, estimate excludes potential
for solar power which is dependent on future developments that might make solar
technology cost-competitive for grid-interactive power generation applications.
