Cape Light Compact Update: Taking Charge of Your

Energy Future

• 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.)

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!

Why is grid mod important?Use cleaner, less expensive power!

How do we use electricity?

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?

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?

What makes up a smart grid?Solar and storage!

What makes up a smart grid?Monitoring and automation of grid!

That’s it!

What part of the smart grid are you excited about?
