India eyes renewables for rural power

One of the few countries in the world with a Ministry of
Non-Conventional Energy Sources, India is using its natural
resources and making strides toward developing advanced technologies
for the energy sector.
"Currently India has an institutional capacity of 125,000
megawatts -- including thermal, hydropower, nuclear power and
renewable energies," said U.N. Panjiar, additional secretary to the
Indian Ministry of Power.
The country faces an average energy shortage of about 8
percent -- and a peak shortage of about 12 percent.
"The energy sector is the buzzword nowadays," Sudhir Mohan, an
adviser in the Ministry of Non-Conventional Energy Sources, told
United Press International.
Under India's Electricity Act of 2003, which lays down the
framework of the power sector's development, the country announced
its National Electricity Policy in 2005. This is aimed at ensuring
availability of electricity resources to all areas. Among other
guidelines, the policy requires government entities to development
the power system based on optimal use of alternative resources.
"The Ministry of Non-Conventional Energy aims at adding about
5,000 megawatts in renewables," Panjiar said. "This level of
capacity addition should take care of the shortfalls in the country
by 2012."
While the Ministry of Power is working to eliminate all energy
shortages by this time, the Ministry of Non-Conventional Energy also
aims at 100 percent Remote Village Electrification by 2009.
Mohan said that this is important because many of the remote
villages under this scheme are unlikely to receive grid-connectivity
to energy resources because of high costs and the level of
difficulty in doing this. As a result, villagers are being taught to
use environmental resources for optimal power.
"Under the rural electrification program, we have 60,000
villages; currently 10,000 remain unelectrified," Mohan said. "At
least 10 percent of total households in each village or hamlet must
be electrified."
About 65 percent of rural Indian households are without
electricity.
Apart from the specific Remote Village Electrification
program, the Indian government is keen to advance technologies using
natural resources: wind, biomass and solar energies being the most
commercial.
Ranking fourth in the world for wind power -- after Germany,
Spain and the United States -- India has an installed capacity of
4,434 MW. According to the Ministry of Non-Conventional Energies,
the country's wind power potential has been assessed at around
45,000 MW, assuming 3 percent land availability for wind farms.
Through investment by the private sector, "people are paying
money, getting machinery installed and being connected to the
grids," Mohan said. The rates for wind power are like those for
typical utilities -- on a 10-15 year agreement plan, users are
typically paying about 3 rupees per unit of electrification (about 6
cents).
Machinery for hydropower mechanisms are being produced in
India, with some components being imported from Scandinavia.
Additionally, the export of wind turbines and components is expected
to reach an estimated $65 billion in 2006.
Small hydropower stations, based mainly in the northern
mountainous states, have been in action for almost 50 years. These
generate about 500MW from streams.
Biomass programs use forestry material and animal waste for
biogas generation -- the waste organic materials are fermented and
generate usable methane gas. After China, India is the largest user
of this form of energy.
"This is mainly used in villages; we have been promoting it
mainly for cooking gas because otherwise villagers cut down trees
for their cooking requirements," Mohan said. Crop residues also form
an aspect of producing energy under the biomass program.
With the highest cattle population in the world, numbers
ranking at about 310 million, the government has instituted the
Natural Biogas and Manure Management Program as a part of its rural
energy programs, using biomass techniques to produce energy from
cattle dung.
Sunshine has encouraged solar energy use. The most common of
these applications are the thermal water heating systems found more
in the temperate climes of south and central India. But these have
yet to become popular, due to the lack of incentives for funding
expensive solar water heaters.
Although research is ongoing to develop solar technology
further, the solar photovoltaic route is being used in greater
capacity to generate light for telecommunications and railway
signals, and even to operate water pumps in remote areas.
Solar photovoltaic is classified by the direct conversion of
solar energy to power. "SPV cannot be bought unless the government
subsidizes it, because the government feels that it is good for the
people, good for the country," Mohan said
Photovoltaic capacity is ranked at about 70MW per year, mainly
used for domestic applications in the hinterlands.
As photovoltaic technology comes at a high cost, the Indian
government has worked out financial incentives "to bridge the gap
between economic and independent financial viabilities," Mohan said.
The government generally gives incentives of about 7 to 30 percent
of system costs, and has an annual expenditure of $10 million.
"We have opened up a lot of solar power shops in villages --
given subsidy and incentives to people to set these up," he said.
According to Mohan, there are about 250 of these shops in the
country.
The government has gone to great lengths to promote
alternative energy use. Hindi-language advertising is on bus stops
in cities, signs promoting alternative energies are visible all over
New Delhi and novel means of promotion for villages have been
introduced. Solar-powered cooking contests have been fairly popular,
Mohan said.
"This technology is bound to come to the cities because we
don't have much conventional energy and resources are limited," he
said. "The sooner we'll be able to develop better technology,
alternative energies will become more attractive."
