WHAT IS SMALL OR MICROGENERATION ?

Microgeneration technologies include small scale wind turbines, hydroelectric plants, photovoltaic solar systems, ground source heat pumps, Micro Combined Heat and Power (MicroCHP), Biogas etc, installations

HOW SMALL IS REALLY SMALL !?

• WIND – up to 100KW / rotor dia < 18M is called small• Solar PV - 5 Watts and up to several KW • Hydro – up to 100KW ( micro) 101KW – 2MW ( mini ) 2MW-25MW ( small )• Biogas – 0.4Kw to several tens of KW

IT IS POSSIBLE GENERATE SEVERAL TENS & HUNDREDS OF KILOWATTS ONSITE , CONSUME ONSITE OR FEED

Wind energy potential

unitron

• The sun radiates 100,000,000,000,000 kWh energy tothe earth per hour

• 3 % of the energy coming from the sun is converted into wind energy

• 3 % of the above wind energy can meet the energy *demand of the “ world “ today

unitron

* Provided we can harness from “CLASS I “ winds and upward

Why Small Wind Energy ?

unitron

WORLD BANK’S SURVEY SAYS

�Only about 12-15 % of the World’s Land Mass has potential for large Multi-Megawatt scale wind power installations

�About 20-25% isn’t any good for Wind Energy

�A whopping 60-65% has potential for small scale Wind Energy !!

Plus

� you don’t need roads …!!� you don’t need cranes ..!!� Less or maintenance…� unattended operation..

AC Coupling is as simple as PLUG and PLAY..!!

unitron

• Continuously monitors Voltage , RPM, intelligently manages load sharing • Voltage tracking range is as wide as 100VDC - 600VDC possible • Can be programmed as per GCI (complying EN 61400-21: 2002 ) characteristics • Always ensures that DC liink voltage is with-in operating range • Low Voltage boost circuit is also incorporated

TYPICAL PORTUGAL GRID TIE SYSTEM

• As per regulations max 3 KW only can be injected into GRID

• By installing 5KW WEG , they are benefitted by better energy export than a 3 KW WEG plus the benefit of “off Grid" power

TYPICAL NORTHERN IRELAND INSTALLATION

• Primarily Wind energy is to heat flooring using specially designed heat storing Granite slab.

• As soon as requirement is met the timer switches off and power is fed into Grid via GCI

Why wind Why wind –– PV hybrids ?PV hybrids ?

• wind – PV resources compliment very nicely

• it has ability to provide continuity of power

• Wind is less predictable than PV, addition of PV improves consistency

• The Wind , PV together with batteries emulate a virtual UPS

unitron

Benefits of Wind in a PV System

�Longer battery life:By simply incorporating a wind turbine into an existing or new PV system, battery life can be extended by as much as 50%.This is due to the variable charge of a wind turbine.

�Lower system cost :Because the cost of wind is much less than PV, the addition of a wind system can reduce the overall cost of a renewable energy system by as much as40 - 45%.

Lacs / KW

How hybrid systems compare with other conventional alternate systems

�1 KW portable generator will cost 0.30 lacs, cost of fuel per year 4 to 5 hours a day 0.50 to 0.60 lacs first year expenses ~ 0.95 lacs

•1 KW inverter with 4-6 hours battery 0.70 – 0.85 lacs , annual energy expense from grid 0.20 – 0.25 lacs @ 6/- per unit first year total expenses ~ 1.10 lacs

� You will notice that cost of alternate systems work out as high as 50% or more of the cost of renewable energy systems by the end of one year of their operation

BY 2020 WORLD WILL BE HOTTER BY 2.5 O C

If the World continues business with as usual approach to Climate Change India would be one of the hardest hit countries , witnessing up to 30% reduction in farm produce .!!

unitron

Last and final call to save our earth !!!

Use of renewable energy of any form or any capacity will make a Great contribution , just 100W = cleaning up of 10 tons of

pollutants !!!

Governments , Stake holders and every one of us around the world can help our “ struggling to live” Planet,

I am sure this CII event, RE in Green Buildings helps us to take another big leap forward in this direction !!
