    our current electric grid was conceived
  • 00:00:04
    more than 100 years ago when electricity
  • 00:00:06
    needs were simple power generation was
  • 00:00:09
    localized and built around communities
  • 00:00:12
    most homes had only small energy demands
  • 00:00:14
    such as a few light bulbs and a radio
  • 00:00:17
    the grid was designed for utilities to
  • 00:00:18
    deliver electricity to Consumers homes
  • 00:00:21
    and then build them once a month this
  • 00:00:23
    limited oneway interaction makes it
  • 00:00:25
    difficult for the grid to respond to the
  • 00:00:27
    ever changing and Rising energy demands
  • 00:00:29
    of the 21st
  • 00:00:31
    century the smart grid introduces a
  • 00:00:33
    two-way dialogue where electricity and
  • 00:00:36
    information can be exchanged between the
  • 00:00:38
    utility and its customers it's a

    technologies and tools working together
  • 00:00:48
    to make the grid more efficient more

    vehicle charging with our participation
  • 00:01:02
    as informed consumers this smart grid
  • 00:01:05
    will replace the Aging infrastructure of
  • 00:01:07
    today's grid and utilities can better
  • 00:01:09
    communicate with us to help manage our
  • 00:01:11
    electricity
  • 00:01:12
    needs the smart home communicates with
  • 00:01:15
    the grid and enables consumers to manage
  • 00:01:17
    their electricity usage by measuring a

    home's electricity consumption more
  • 00:01:22
    frequently through a smart meter
  • 00:01:24
    utilities can provide their customer
  • 00:01:26
    with much better information to manage
  • 00:01:28
    their electricity bills
  • 00:01:30
    inside the smart home a home area

    solar are a sustainable and growing
  • 00:02:01
    source for electric power however
  • 00:02:04
    Renewable Power sources are variable by
  • 00:02:06
    nature and add complexity to normal grid
  • 00:02:09
    operations the smart grid provides the
  • 00:02:11
    data and automation needed to enable
  • 00:02:14
    solar panels and wind farms to put
  • 00:02:16
    energy onto the grid and optimize its
  • 00:02:18
    use to keep up with constantly changing
  • 00:02:21
    energy demands utilities must turn power
  • 00:02:23
    plants on and off depending on the
  • 00:02:25
    amount of power needed at certain times
  • 00:02:27
    of the day the cost to deliver power
  • 00:02:29
    power depends on the time of day it is
  • 00:02:31
    used electricity is more costly to
  • 00:02:34
    deliver at peak times because additional
  • 00:02:36
    often less efficient power plants must
  • 00:02:38
    be run to meet the higher demand the
  • 00:02:41
    smart grid will enable utilities to
  • 00:02:43
    manage and moderate electricity usage
  • 00:02:45
    with the cooperation of their customers
  • 00:02:47
    especially during Peak demand times as a
  • 00:02:50
    result utilities will be able to reduce
  • 00:02:52
    their operating costs by deferring
  • 00:02:55
    electricity usage away from peak hours
  • 00:02:57
    and having appliances and devices run at
  • 00:02:59
    other times times electricity production
  • 00:03:01
    is more evenly distributed throughout
  • 00:03:03
    the day the power being used right now
  • 00:03:06
    was generated less than a second ago
  • 00:03:08
    many miles away at each instance the
  • 00:03:11
    amount of electricity generated must
  • 00:03:13
    equal the consumption across the entire
  • 00:03:15
    grid smart grid Technologies provide
  • 00:03:18
    detailed information that enables grid
  • 00:03:20
    operators to see and manage electricity
  • 00:03:23
    consumption in real time this greater
  • 00:03:26
    insight and control reduces outages and
  • 00:03:28
    lowers the need for people power in
  • 00:03:31
    control rooms across the grid Engineers
  • 00:03:33
    will be able to more precisely and
  • 00:03:35
    predictably manage electricity

    automatically identifying problems then

    rerouting and restoring power delivery
  • 00:04:18
    utilities can further use distribution

    intelligence to predict and manage
  • 00:04:22
    electricity usage with the cooperation

    across the household and prioritize
  • 00:04:40
    between the electric vehicle and other
  • 00:04:41
    appliances to manage electricity usage
  • 00:04:44
    and reduce costs with smart grid

    Technologies and consumer participation
  • 00:04:49
    utilities can more easily handle the
