India 2006 – The Power scenario
Power Shortage is a major problem for India - leads to compounded problems with Low frequency, tripping of generators and Load shedding in nearly all parts of the country.
Poor power factor, a feature of poor quality equipment, leads to low voltage. Use of equipments to correct voltage further compounds the problem.
Power shortage/quality thus leads to large scale use of Voltage Stabilisers, Inverters, Generators, UPS Systems, etc.
Such Electrical Equipments, which require unwanted investments, in turn not only lead to enhanced shortage in the overall situation but also cause air and soil pollution by burning of coal, diesel, etc.
Widespread use of lead-acid batteries in these equipments further causes pollution of soil and water.
What is the effect of Stabilisers?
Voltage Stabilisers don’t have efficiencies better than 80%. While a 1.5 Tr AC consumes 2 units; its stabiliser consumes 0.4 units; it even consumes power if left ON when AC is OFF.
Assuming we have 10 Million ACs in India; on account of stabilisers for ACs alone we lose around 4 million units, even during peak hours, which is double the power generated by many large generating stations.
Assuming an AC runs for 5 hours in a day, this means a loss of 20 million units per day.
What is the effect of Inverters?
The average efficiency of the domestic inverters is 50% and unlike fuel-based generators, inverters don’t generate power.
There is an estimated 50 million inverters being used for domestic purposes each consuming say 250W/day or 0.25 units. The power drain by inverters is thus to the tune of 12.5 million units.
Further, inverters use lead-acid batteries which severely pollute the environment.
Power loss – Pumps & Motors
Pumps/Motors consume roughly 20% of total electricity in India. An estimated 75% of this is consumed by the pumps for agricultural sector mainly for water/irrigation. The balance is for other motor applications.
Most Indian pumps operate at 33% efficiency while motors have an average efficiency of 40%. These cause heavy loss of electrical energy.
Taking usage of 4 units at 4 hours/day, the consumption in this category is over 250 million units/day and the estimated loss is 160 million units/day.
