Gallery: Energy 101: What Is a Smart Grid?

 

In last week’s Energy 101 column, we took a look at the basics of where our energy comes from now. This week, we’re examining the future of energy—specifically, the smart grid. To recap, a smart grid is essentially a modernization of the transmission and distribution aspects of the electrical grid. In terms of transmission, a smart grid makes it easier to deliver alternative energy sources like wind and solar from rural installations to city centers. Without transmission lines, alternative energies are stuck where they’re produced—oftentimes in the middle of nowhere.

    smart grid is a vision to upgrade the existing grid with help of modern communication technologies, real time computational techniques and advanced sensors to improve the efficiency and reliability.

    SG doesnt cover our needs, indeed. There is no way to stop producing coil, gaz power plants in 20-40 years to cover uninspected demands with uninspectorate(wind) and unreliable (alternative) power producing.
    When one construct smart grid utilities can predict or coordinate power consumption, but what we should do when wind suddenly stops night? thats why Grid need a “warm” standby coil plants.
    All we need NOW is to rationalize existing grid with SMARTGRID project and may be think about transmition lots of Megawatts from east to west to cover US power demands. Make kind of National Super-Grid network.
    And on default make investments in alternative energy researches.

    Your perspective would change dramatically if you were to install a solar or wind system at your own residence. I don’t have the time or desire to list the many ways you are wrong. solarjohn

    The “Smart Grid” is a rationing device. Nothing more. Nothing less.

    Rationing is what you do when you cannot meet real needs.

    Can’t afford promised Social Security benefits? Raise the retirement age to 67 and beyond, and call it “Social Security Reform”. Can’t afford universal healthcare? Ration services, and call it “Healthcare Reform”.

    Rationing. Waht you do when you *know* that wind, solar, geothermal, etc simply cannot fullfill our energy needs. Certainly not today, and maybe not ever.

    We need to use all the tools we have available today so that wind, solar, and geothermal can take their CURRENTLY rightful places as SUPPLEMENTARY sources of energy.

    Maybe the solution will be to concentrate on demand side innovations (DSI) of the EWPC Regulatory Framework instead of demand side management (DSM) of the IOUs Regulatory Framework.

    Zero net energy homes are already in the making. The Rocky Mountain Institute has one demonstration. Among many other DSIs, breakthroughs are expected, for example, in regenerative net output energy buildings.

    Please take a look at the EWPC article Forget Demand Side management (DSM); Think Demand Side Innovation (DSI) in the Internet hyperlink http://www.energyblogs.com/ewpc/index.cfm/2009/4/7/Forget-Demand-Side-management-DSM-Think-Demand-Side-Innovation-DSI

    The NE gets electricity from COAL, from the Mid-West.Other parts of the country may also.
    I thought ‘smart-grid’ existed BETWEEN tectonic plates.
    What’s the story?
    I can’t believe wind and solar will provide enough power to heat our homes, provide for our appliances,
    drive our cars anytime soon.It gets very cold in the North and for those having a continental climate.

    In a single paragraph…

    The goal of a smart grid is to collect and provide the optimal amount of information
    necessary for customers, distributors and generators to change their behavior in a way
    that reduces system demands and costs, increases energy efficiency, optimally allocates
    and matches demand and resources to meet that demand, and increases the reliability of
    the grid. The social benefits of a smart grid are reduced emissions, lower costs, increased
    reliability, greater security and flexibility to accommodate new energy technologies,
    including renewable, intermittent and distributed sources.

    The above Smart Grid definition is bound to change sooner than the 5 or 10 years you may get it at home. For example, the distinction between transmission and distribution (T&D) will end, as a T&D regulated transporter will be needed.

    The Smart Grid definition is based on the obsolete Investor Owned Utilities (IOUs) Framework under the policy E1P2 (economics first, performance second). The emerging Electricity Without Price Control (EWPC) Framework will replace the IOUs Framework with a P1E2 policy to enable organic business model innovations that will replace the big bets that state regulators are being forced to make right now.

    To get introduced in the issues read the EWPC article “Why President Obama Needs to Keep Working on Energy” in the internet hyperlink http://www.energyblogs.com/ewpc/index.cfm/2009/4/30/Why-President-Obama-Needs-to-Keep-Working-on-Energy
