  • Alexander Graham Bell – would he recognize your cell phone as being the same as the phone that he invented?
  • According to smartgrid.gov: What Makes a Grid “Smart?”
    In short, the digital technology that allows for two-way communication between the utility and its customers, and the sensing along the transmission lines is what makes the grid smart. Like the Internet, the Smart Grid will consist of controls, computers, automation, and new technologies and equipment working together, but in this case, these technologies will work with the electrical grid to respond digitally to our quickly changing electric demand.
  • What’s different about the generators on the left and right? Dispatchable vs. intermittent, emissions, pay for fuels vs. free fuels, located far from where we use electricity vs. on or next to our homes, etc.
  • Modern grid makes reduces the number of people that lost power when something impacts the system, and makes it easier and faster to find the problem and fix it. Right now, if something breaks, the utility has to go out and look for the problem!

  • Can talk about how, today, only know how much electricity we use over the course of a month, and even then, only several weeks later. Would be like if teacher only graded papers and quizzes at the end of the year! Smart meters can provide real-time data to phones and computers (and in Worcester, digital picture frames, pictured) so that we can see how we’re using electricity in real time.
    Might ask them to think about how electricity usage on the Cape might be different than national averages.
  • Hot water heater, washer/dryer, fridge (defrost cycle actually warms up the freezer to melt ice!), dishwasher
  • Smart grid – gives grid operators more information on when solar and wind are producing electricity, so that the grid operator can better manage the grid, and efficiently dispatch other sources of power. Also, soon be able to use batteries to power homes when the electricity goes out (longer if paired with solar), and can send electricity to the grid when electricity is scarce, and store it when solar and wind are producing a lot of electricity!
  • Kind of a catch-all to remind that there grid mod includes things we can’t see – better data collection to better plan modifications to the grid, CVO, VVR, etc. Boring things, so focus is just on the fact that there are other, grid-facing things happenening.
  • Taking Charge of Your Energy Future

    1. 1. Cape Light Compact Update: Taking Charge of Your Energy Future
    2. 2. • What is it? – Telephone progress vs. electric grid progress – What is it – schematic • Why? – Renewables/emissions – Savings – show buildup of graph – Reliability – outages – currently have to visually inspect! – Make it more efficient, other? • How – Meters – Appliances (what could you shift?) – thermostat, lights, washing machine, dishwasher, – Renewables/storage – Electric vehicles – Other technologies (communications, CVR/VVO, etc.)
    3. 3. Technological progress: phone system 7
    4. 4. Technological progress: electric grid 7
    5. 5. What is grid modernization?
    6. 6. Why is grid mod important? More renewables! 7 VS.
    7. 7. Why is grid mod important? Build fewer wires and generators! Do we build roads large enough for everyone to drive on them at the same time?
    8. 8. Why is grid mod important? Build fewer wires and generators! - 5,000 10,000 15,000 20,000 25,000 30,000 January '14 All of 2014 All-time record New England Electricity Load (MW) Peak 2014 average With electricity, we have to have enough wires and generators to meet all of the demand at once! On average, we use this much, but… We have to plan (and build wires, and poles, and generators, etc.) for this much!
    9. 9. Why is grid mod important? Use cleaner, less expensive power! 11,000 12,000 13,000 14,000 15,000 16,000 17,000 18,000 12:00AM 12:25AM 12:50AM 1:15AM 1:40AM 2:05AM 2:30AM 2:55AM 3:20AM 3:45AM 4:10AM 4:35AM 5:00AM 5:25AM 5:50AM 6:15AM 6:40AM 7:05AM 7:30AM 7:55AM 8:20AM 8:45AM 9:10AM 9:35AM 10:00AM 10:25AM 10:50AM 11:15AM 11:40AM 12:05PM 12:30PM 12:55PM 1:20PM 1:45PM 2:10PM 2:35PM 3:00PM 3:25PM 3:50PM 4:15PM 4:40PM 5:05PM 5:30PM 5:55PM 6:20PM 6:45PM 7:10PM 7:35PM 8:00PM 8:25PM 8:50PM 9:15PM 9:40PM 10:05PM 10:30PM 10:55PM 11:20PM 11:45PM New England Load, 1/11/2016, MW $ $$ $ $$$$
    10. 10. Why is grid mod important? Make it more reliable! Do we build roads large enough for everyone to drive on them at the same time?
    11. 11. What makes up a smart grid? Smart meters!
    12. 12. What makes up a smart grid? Knowing how we use electricity!

    13. 13. What makes up a smart grid? Smart thermostat! What could you do with a thermostat that knew how much electricity cost, or how much solar power was available?
    14. 14. What makes up a smart grid? Smart appliances! What things that use electricity could you use less of or use at other times when electricity is scarce?
    15. 15. What makes up a smart grid? Solar and storage!
    16. 16. What makes up a smart grid? Monitoring and automation of grid!
    17. 17. That’s it! What part of the smart grid are you excited about?
