3. INTRODUCTION
Utilization of power increased day
by day due to large power
utilization.
The power distribution in huge
computing environment need to
be control.
4. SMART GRIDS
“A smart grid delivers
electricity from suppliers to
consumers using digital
technology to save energy,
reduce cost and increase
reliability.”
5. What Smart Grids really mean
Cost Implications*

More choices
Includes renewables
Better quality and
service
Greater resiliency /
robustness
Increased efficiency
and asset utilization
6. A Smart Grid is a Transformation of the power system based
on harnessing digital communications and control
Utilities will be able to:
Know what power is going where, and when
Charge “appropriately” for it
Control the use of (if not flow) power
Although Advanced Metering Infrastructure (AMI) is
considered to be the basic building block for a Smart Grid,
the Smart Grid is not just AMI!
The Smart Grid is a much broader set of technologies and
solutions
8. The Future will be Different
Consumers may become generators
Possibly with distributed and/or renevables
IT has improved to the point where even smaller consumers
(residences) can meaningfully participate in utility load control
schemes
Residences are a major part of the Indian peak
The future should have ZERO load-shedding (at a feeder level, at
least)
Discrimination across and within categories of consumers is
present today and may remain
Let’s do it more intelligently
Incentivize behavior at the margin
Provide a minimum assured supply 24/7
9. Buying Peaking Power
Peak power is always more expensive than the
average
Plants operate at only 500 or 1000 hours per year
Ignores 15% target spinning reserves, today articulated
as 5% by GoI
Blending such peak power today is what the West
does
Raises the costs for ALL users for ALL kWh
KN example – Raises purchase cost for utilities by Rs.
1/kWh!
Alternative – peaking tariff – let those who
contribute to the peak pay for it
Requires appropriate metering
14. Thinking of the Future…We need
Smart Grids
Business as usual (BAU) will not be sustainable
o Adding supply is necessary but not sufficient – must make
consumption smarter
Consumers must see and behave based on not just their
average costs but their incremental impact on the grid
o This will create a few losers but (hopefully) more
winners
Appliances and consumption will become smarter
o Whirlpool announced that by 2015 ALL their selected
household appliances will be smart grid capable
(worldwide)
o It’s not a question of when, not if…
