Power Growth Perspective in IndiaPower Growth Perspective in India

Electricity demand growing @ 8% annually

Capacity addition of about 130,000

MNREMNREMNREMNRE

Capacity addition of about 130,000

MW required in the next 10 years

Challenge is to meet the energy needs

in a sustainable manner

GRID INTERACTIVE RENEWABLE GRID INTERACTIVE RENEWABLE POWERPOWER

The Government aims at 10-12 percent of the gridinteractive power generation installed capacity fromrenewable by the end of the 11th Plan (2007-2012)

MNREMNREMNREMNRE

Deployment of renewable power during the 10th plan hasmade it the second largest source after conventional power.

A target of 14,000 MW capacity addition has been plannedfor the 11th Plan (2007-08 to 2011-12).

Wind Power Technology

Wind Energy - What is it?

Wind is the natural movement of air across the land

MNREMNREMNREMNRE

Wind is the natural movement of air across the land or sea. Wind is caused by uneven heating and cooling of the earth's surface and by the earth's rotation. Land and water areas absorb and release different amount of heat received from the sun. As warm air rises, cooler air rushes in to take its place, causing local winds. The rotation of the earth changes the direction of the flow of air.


Advantages

Fastest growing commercially developed source ofrenewable power generation.

MNREMNREMNREMNRE

Environment friendly

Cost of generation reduces over a period of time

Lowest gestation period.

Direct and indirect employment benefits in rural areas

Low O&M Costs.


Limitations of Wind Energy

Can be located only where strong and dependable

winds are available.

MNREMNREMNREMNRE

winds are available.

Wind is intermittent and hence infirm power

Wind towers and blades subject to damage from very

high wind and lightning

Electricity produced by wind sometimes fluctuate in

voltage and power factor

State-of-the-art technology available in India


PROGRAMME COMPONENTS

To assess wind power potential

To identify suitable sites for wind power projects.

MNREMNREMNREMNRE

To identify suitable sites for wind power projects.

To set up demonstration wind farm projects

Promotional policies for creating conducive environment for

private sector investment

Research & Development


Present Status Growth in installed capacity - 11000 MW as on Feb, 2010

Centre for Wind Energy Technology and Wind Turbine Test Station have beenset up to provide support to industry, wind resource assessment, Testing andcertification of new turbines

MNREMNREMNREMNRE

certification of new turbines

Export of wind turbines and blades to USA, Europe, South America and Asiancountries : Import / Export – Rs. 2200 crore / Rs. 4500 crore

Establishment of wind energy industry in India

* 14 major players in the sector

* Indigenisation – about 80 to 50%

* Vendor development – parts and components including rotor blades,gear boxes, yaw components, nacelle cover, raw material for bladesbeing manufactured


Wind Resource in India

Winds in India influenced by

� Strong South-West Summer Monsoon (April-September)

� Weaker North-East Winter Monsoon

1150 wind monitoring stations in 32 States/UTs established.

MNREMNREMNREMNRE

1150 wind monitoring stations in 32 States/UTs established.

Seven handbooks on Wind Energy Resource

States with high potential

• Andhra Pradesh • Gujarat • Karnataka • Kerala

• M.P. • Maharashtra • Rajasthan • Tamil Nadu

216 sites with annual average wind power density > 200 Watts/m2

A Wind Atlas for India using models like WAsP and KAMM is underfinalisation.

Wind Potential in India

Wind Power Development in IndiaRegulatory Framework

The Electricity Act-2003

Section 86(i)e: The State Commission shalldischarge the following functions, namely:

promote cogeneration and generation of electricity

MNREMNREMNREMNRE

promote cogeneration and generation of electricityfrom renewable sources of energy by providingsuitable measures for connectivity with the gridand sale of electricity to any person, and alsospecify, for purchase of electricity from suchsources, a percentage of the total consumption ofelectricity in the area of a distribution licensee

Regulatory Framework

As per National Electricity Act-2003, state regulators to specify aminimum percentage of power to be purchased from renewablesources.

RPOs have been announced by major states

MNREMNREMNREMNRE

RPOs have been announced by major states

As per National Tariff Policy-2005, state regulators to providepreferential tariff for renewable power. Tariff rates offered in therange from Rs. 3.00 to Rs. 4.58/kwh (7-10 US cents/kwh)

The purchase of renewable power in the near term would bebased on competitive bidding within each renewable resourceand in the medium term within all renewables. In the long term,however, would need to compete with conventional power.
