Supergrid

Supergrid

• By Table 1 - Paul Kim, Issac Jin, Andrew
  Mkrtchyan, Ryan Lee

How It Works

• Energy is transported in bulk
• with high voltage current lines
• Currently, people are advocating
• whether to use HVAC (high-
• voltage alternating currents) or
• HVDC (high-voltage direct
• currents)
• HVAC are not suitable for long
• range transmission but HVDC
• are expensive to instate.

3
Suitability

• -Long Distance
• Transmission Lines
• -Utilize distantly located
• renewable energy
• sources.
• -Best suited as a
• unified grid to provide
• electricity over a large
• area of land.

4
How realistic is this energy currently?

• Recently a new circuit breaker was developed that
  makes it possible to join high-voltage direct
  current transmission lines to form a resilient
  power grid. This grid will be able to combine
  power from widely distributed wind turbines and
  solar panels efficiently.

5
Likelihood/Viability

• -4-step Process
• -High cost to overhaul
• -Time-consumption
• -Manual labor
• Conclusion Supergrids won't
• be up and running this half
• of the century.

6
Advantages

• - Reduces energy wastage
• - Area of bulk storage
• - Accesses sources of renewable energy
• - Takes advantage of remote sources
• - Ensures energy supply in any one area
• - Evens out variations in the supply and demand
  of energy
• - EX Wind power

7
Advantages Continued

• - Getting the best available price for
  electricity
• - Can move energy from cheaper areas
• - At times, it can be A LOT cheaper
• - EX Proposed 19,00 miles in U.S. costs 60
  billion, but averages out to about 35 cents per
  average household
• - Greater leap towards clean energy! Her-Ray!

8
Disadvantages

• - Amount of land area and space used
• - Speculated political arguments and dilemmas
• - Challenge of coordinating national energy
  regulations
• - Too risky and costly
