2. INTRODUCTION Power System Fact Current Scenario
Today’s electricity system is percent reliable, yet still
allows for power outages and interruptions that cost Americans
at least $150 billion each year — about $500 for every man,
woman and child.
Current Scenario
In 2009, over 16 percent of all energy used is expected to be in the
form of electricity, up from 9 percent in Currently, the average
efficiency of the world's legacy electricity grids is around only 33
percent. This contrasts with 60 percent efficiency for grids based on
the latest technology.

3. SMART GRID A smarter grid applies technologies, tools and techniques
(ICT) available now to bring knowledge to power
knowledge capable of making the grid work far more
efficiently...
Ensuring its reliability to degrees never before possible.
Maintaining its affordability.
Reinforcing our global competitiveness.
Fully accommodating renewable and traditional energy sources.
Potentially reducing our carbon footprint.
Introducing advancements and efficiencies yet to be envisioned.

4. SMART GRID IN A NUTSHELL
Broadly speaking, Smart Grid companies add computer intelligence and networking to what is otherwise a 'dumb' electrical network.
Other examples of Smart Grid activities include: making the process of traditional electricity generation more efficient; connecting sustainable energy sources to the existing grid, and smart meters.

5. SMART GRID: GREEN
For example, some Smart Grid technologies assist with load leveling of the electrical grid. This allows a power generating company to run cleaner power sources, such as nuclear or hydroelectric, at full output, 24-hours a day, while reducing the need to provide more carbon emitting gas, coal or oil plants in a surge (usually for only a couple of hours per day), to meet peak demand. Further, by reducing variability in demand, fewer new power plants need to be constructed.

8. BACKGROUND
Many utilities are somewhere in the process of developing a roadmap for
implementation of a communications, control, and data management
architecture that can facilitate monitoring, control, and automation functions at
all levels of the power system. This “smart grid” will provide opportunities for
improving reliability, energy efficiency, management of assets, customer
services, and demand management.
One of the keys to success in implementation of a smart grid that can enable a
wide range of intelligent applications well into the future is to use a standards based
approach and focus on interoperability of technologies. Requirements
for technologies and systems are being developed through the
characterization of advanced applications that will use the technologies – use
cases. There is an opportunity for the industry to enhance the interoperability
of technologies and the development of appropriate standards through the
sharing of use cases and common requirements that are developed from
these use cases

10. SMART METERING
Advanced Metering Infrastructure (AMI) is an approach to integrating consumers based upon the development of open standards. It provides consumers with the ability to use electricity more efficiently and provides utilities with the ability to detect problems on their systems and operate them more Efficiently. AMI enables consumer-friendly efficiency concepts like “Prices to Devices” to work like this: Assuming that energy is priced on what it costs in near real-time – a Smart Grid imperative – price signals are relayed to “smart” home controllers or end-consumer devices like thermostats, washer/dryers and refrigerators – the home’s major energy-users. The devices, in turn, process the Information based on consumers’ learned wishes and power accordingly. The house or office responds to the occupants, Because this interaction occurs largely “in the background,” with minimal human intervention, there’s a dramatic savings on energy that would otherwise be consumed. rather than vice-versa.

11. INTEGRATED RENEWABLE ENERGY SYSTEMS

12. DISTRIBUTED GENERATION
Distributed generation is the use of small-scale power
generation technologies located close to the load being
served, capable of lowering costs, improving reliability,
reducing emissions and expanding energy options.

13. BOTTOM LINE
Major manufacturers and utilities should explore partnerships with, and consider acquisitions of, smart energy companies. Companies should not be distracted by falling oil prices. Supply remains volatile, and demand uncertain. And while the price of oil has dropped over 50 percent from its 2008 peak, energy costs remain well above their long-term trends.
Governments around the world should look at the cost effectiveness of trade offs between sustainable energy subsidies compared with commitments to upgrading the existing grid. The global downturn may make significant government support for SmartGrid spending unlikely, although some administrations are likely to adopt a policy of stimulative infrastructure spending on their electrical grids, some of which will be for SmartGrid equipment. But profit-oriented utilities and enterprises should continue to explore and deploy SmartGrid technologies that offer high returns on investment, even without government support, to conserve costs.
Governments unable to finance SmartGrid investment could instead promote the technology via information campaigns and stimulate adoption through tax incentives. And as governments increasingly focus on energy security, investing in the SmartGrid could be used to reduce dependence on non-domestic energy sources. It could also make the grid more resistant to military or terrorist attacks, by physical or digital means.
Venture capitalists (VC) should devote increasing resources to understanding smart energy technologies. VC investment in the sectorm remains strong, even during the current economic crisis, with SmartGrid companies receiving the second largest slice of the GreenTech pie, behind only solar energy.

14. SMART GRID 2030

15. INVENTION
In celebrating the beginning of the 21st century, the National
Academy of Engineering set about identifying the single most
important engineering achievement of the 20th century. The
Academy compiled an estimable list of 20 accomplishments
which have affected virtually everyone in the developed world.
The internet took thirteenth place on this list, and “highways”
eleventh. Sitting at the top of the list was electrification as
made possible by the grid, “the most significant engineering
achievement of the 20th Century.”
