THE SMART GRID VISION FOR JODHPUR POWER UTILITY
THE SMART GRID VISION FOR JODHPUR POWER UTILITY.pdf (Size: 789.04 KB / Downloads: 61)
The Smart Grid is the future of the electric industry
The Smart Grid results from a convergence of powerful forces
Today, the Smart Grid is still a vision more than a blueprint
But infusing T&D networks with computing and telecommunications capabilities is the
heart of the Smart Grid vision
Smart Grids could radically transform the way electricity is produced, transported and
used
Important dimensions include:
· T&D automation to enhance operational efficiency and reduce cost
· AMI + demand response to optimize energy usage
· Promote RE and EE to reduce carbon emissions

Electricity is the premium form of end-use energy
Electricity is the premium energy source for an increasingly digital world
Growth in demand for electricity is unrelenting
· Population growth and increasing affluence feed demand for reliable power
Electricity is the fastest growing form of end-use energy
· Non-OECD countries will use 58% of world energy by 2030
· US energy needs met by electricity grew from 20% in 1960 to 40% in 2000
· This is a harbinger of the global future

India’s power sector has added challenges
Supply shortfalls
Peak load management issues
Higher technical and commercial losses
Increasing global competition for resources
Challenges for Jodhpur Power Utility
High Solar potential
Higher technical and commercial losses
About 40% agriculture consumption with no economic incentive to use
efficiently
Dispersed Geographical area

The power sector is also one of the biggest carbon emitters
India’s installed thermal power generation capacity represents 60% of net generation
capacity and 57% of greenhouse gas emissions
Based on current plans, this scenario will likely continue until 2020
Thus, the national goal to install 20,000 MW of solar power
by 2020
Wind and other renewables are growing rapidly too
Smart Grids are needed to enable grid management to
cope with the unique “dispatchability” characteristics
of renewable energy sources

An historic convergence is reshaping the electric business
Relentless growth in electricity demand as the premium
form of energy
Demand for higher quality by more discerning and
affluent customers
Meanwhile, technological advances in information and communications technology
(ICT), metering and generation
are key enablers
Continued reductions in the cost of technology vastly
expands its scope
The climate change crisis is driving the need for an urgent reduction in carbon emissions
– and thus a much more
efficient power sector
The traditional business model is troubled and implementation
of a Smart Grid vision may facilitate a reinvention of the business

Technological “leapfrogging” offers intriguing possibilities
Investment in a smart grid today may enable India to leapfrog into a vastly improved
electricity scenario.
Even under a business-as-usual case, the GOI will have to invest heavily in the power
sector over the next two decades and beyond.
Smart grid technologies could enable India to leapfrog into a much more advanced
grid infrastructure and electricity market, and more quickly achieve parity with
developed economies.

What, exactly, is a Smart Grid?

The Smart Grid is a vision more than a blueprint
The Smart Grid can’t be reduced
to a simple formula.
The broadest interpretation sees the
electric industry transformed by the
introduction of two-way communications
and ubiquitous metering and measurement.
It will enable creation of more reliable,
more efficient and more secure electrical
infrastructure
Key characteristics of the smart grid
Self-healing: The grid rapidly detects, analyzes, responds,
and restores
Empowers and incorporates the consumer: Ability to
incorporate consumer equipment and behavior in grid
design and operation
Tolerant of attack: The grid mitigates and is resilient to
physical / cyber-attacks
Provides power quality needed by 21st-century users: The
grid provides quality power consistent with consumer and
industry needs
Accommodates a wide variety of supply and demand: The
grid accommodates a variety of resources, including
demand response, combined heat and power, wind,
photovoltaics, and end-use efficiency
Fully enables and is supported by competitive electricity
markets.

But where does the customer fit in?
ARC + GCR = QCS is the formula for Quality Customer Service [Availability, Reliability,
Cost + Good Customer Relations]
For many, the as-delivered service may “feel like” ARC + GCR
Much of the Smart Grid is focused on other results, e.g.
· Reducing carbon emissions
· Improving the efficiency of the networks
· Promoting renewable energy and energy efficiency
· Enhancing security of supply
But customer uptake will be critical to achieving full benefits

Customer response is a critical success factor for Smart Grids
Customers want utilities to produce benefits, including
Reduced Monthly Electricity Bill
Reduced outages
Increased control over energy consumption and cost via better data on usage and usage
patterns (like telcoms)
More choices for energy sources
Options to supply energy to the grid
Green choices to increase environmental sustainability
· The price differential between peak power vs. solar and diesel generation alternatives
is shrinking
