Introduction to Smart Grid
Presentation to Clark University “Greening the Corporation” Sept 29, 2010

National Grid:an international electricity and gas company
50% US, 50% UK
27,000 employees
Distributes electricity to 3.3 million customers
Provides natural gas to 3.5 million customers
Services 1.1 million customers of Long Island Power Authority (LIPA)
Currently owns over 4,000MW of generation
Gas
Electricity

National Grid: An international electricity and gas company
Gas Distribution - UK Transmission – Electricity and Gas - UK
Owns the high-voltage electricity transmission system in England and Wales and operates the system across Britain. Also owns and operates the high pressure gas transmission system in Britain.
Operates the UK gas distribution system; distributes gas on behalf of shippers and suppliers to 11 million consumers but has 20m+ meters

Regulatory Environment Natural Monopoly
Deregulation of Generation Assets
Pipes and Wires – Distribution Regulation by State PUCs
Commodity Charge as Pass through Currently appears as an average KW price

Energy Market is evolving
Traditional Energy Market - supply driven Today’s Evolving Market - customer driven
Coal/gas fired power station
Energy volume drives energy
company revenue
Small range of conventional technologies
Large centralised generation
Static infrastructure

Market Challenges Climate Change
Reduce our emissions of greenhouse gases
Reshape markets by aligning regulatory and public policy incentives
Encourage energy efficiency
Modernizing relationship with consumers
Ageing Infrastructure and Skills
Investment in Transmission and Distribution
Enhance ability to handle renewable generation
Support through regulatory framework

Technology has a key role… Smarter grids and smart metering

Smart Technology DefinitionTechnology that provides advanced information, automation and control capabilities to help us to distribute, measure and use energy more efficiently, reliably, safely and sustainably – all the
way from the point of generation to consumer appliances
Smart technology means different things to different people – a common language and vision are essential
What does it allow you to do?What is Smart Technology?
Automatically optimize selected home appliances Demand response programs Improve satisfaction levels
Hom
e
Customer portal & Home Area Network Automated thermostats, switches,
plugs & appliances Load controllers e.g. PHEV controller
Met
er
Meter that records interval data 2-way communications, remote configuration Informative display Meter Data Management System
Automatic meter reading Enable customer choice and control Choice of tariffs e.g. time of use – peak shifting Catalyst and validation of Energy Efficiency programs Remote configuration
Grid
Sensors & measuring devices Analytical programs e.g. pattern recognition Automatic switches & controls Decision support tools & graphical interfaces
Enable Distributed generation Remotely detect, diagnose, predict and correct
network problems & faults Condition-based, preventative maintenance Automatic fault prevention, isolation & restoration

The prime logic for Smart Grid? – Customer and Environmental Orientation.
The “one ratepayer” approach to serving residential and small
business customers must evolve, we will have to be more innovative to satisfy customers going forward.
The trend to increased consumer choice and control will be different
for customers dependent upon their circumstances
and needs – more segmentation will occur.
With increasing volatility in energy prices, and
climate change becoming a more prominent public concern, customer needs
are changing.
Customers need the “tools” to play their part in the shift towards a new
energy future.
The deployment of Smart Grid technologies will enable the shift in customer behavior towards Energy Efficiency, Energy Management and increase Customer Service levels.
