Using Technology for Electricity improvements The Smart Grid Using Technology for Electricity improvements

What is the “Smart” Grid? The Grid Network of Transmission, Substations, Transformers The “Smart” Grid Using Technology in 4 ways to Improve the overall system 1) Modernize Into a More Efficient Transmission System 2) Increase Reliability 3) Use Technology to Track and Provide Incentives to Reduce Peak Demand 4) Integrate in Renewable Energy Sources

PRODUCTION AND TRANSMISSION OF ELECTRICITY 9,200 units producing 1 Million MW of Generating capacity The U.S. is still dependent primarily on coal for generation THERE IS NO “National Grid”…

WHO USES ELECTRICITY? Residential / Homes are the biggest users

So How Can the “Smart” Grid Reduce Costs and Reduce Energy Production at the same time? Coal, Nuclear - Base load Renewable – Fluctuates NaturalGas Base and Peakers Electricity Produced There is an Instantaneous transmissionof power from generation across grid Transmitted Power must be immediate consumed or lost. (Electricity storage options are limited) Consumed IF INFORMATION AND PRICE SIGNALS CAN FLOW QUICKLY BOTH WAYS, USERS CAN GET LOWER PRICES IF LOAD IS SHIFTED …(RESULTING IN LOWER RESERVE/STANDBY MARGINS ), …ULTIMATELY AND COAL BASELOAD PLANTS CAN BE REDUCED AND RENEWABLES INCREASED

EXAMPLES OF CURRENT LOAD FLUCTUATIONS SYSTEM HAS TO BE BUILT TO MEET A ONE TIME PEAK It is not uncommon for prices to spike 5 to 10 times the normal rate for short and brief intervals of power demand

What Can Information and Technology do to make the “Smart” Grid work?

More Efficient Transmission: …will better integrate devices that will allow operators to receive digital information from and communicate with the grid.

Increased Reliability: Distribution Intelligence 2003 “domino style” blackout caused by a single sagging power line hitting a tree More efficient and timely relay of information will prevent these disasters in future

Facilitate Consumer Engagement http://www.youtube.com/watch?v=JwRTpWZReJk Facilitate Consumer Engagement Technology Pricing incentives to reduce peak demand

INTEGRATE RENEWABLES The large varying degree of wind and solar supply can only be balanced in a fully integrated system that can balance load and demand instantaneously

Smart Grid is not just about utilities and technologies… Giving the information and tools you need to make choices about your energy use It will have millions of different pieces and parts Ranging from controls, integrated computers, new lines and new technology Will probably take at least a decade to build – will be a long extensive process When done will bring a transformation on the way electricity is produced and consumed
