First Electric Bill

Received first electric bill today since owning Model S (PG&E, CA) and based on switch to electric vehicle rate program (with time of use) for entire household our monthly bill.....dropped over 25%!! We could not be happier. Thanks P&G for your EV rate program. If you live in CA and have not signed up for this program, recommend it!

Man you're lucky. My electric bill is double now, not that I'm complaining really. I have relatively good rates, and I am of course spending way less than I used to spend on gas.

I'd say get some solar panels, if you get a 'backwards' running meter from your utility company.

Something I'd like TM to announce would be an in-house battery-pack. Flat, or housed in a box (like the size of a fridge or washing-machine), then the solar panels could charge the battery-pack during the sun-hours and the battery-pack could charge the car during the night.

Then you'd even be able to use some of that harnessed power to charge various other devices (phones, tablets, cameras, laptops, etc)

Already exists--Elon ported his technology over to SolarCity:

Yeah I'm definitely thinking about solar. I'm going to a local Tesla meetup in about a week, and I'm going to ask around if anyone else has looked into it.

@jp, thanks for the link. That looks interesting, but you can only lease the battery system in CA. I bet it's pretty expensive otherwise.

olanmills...FWIW, I'm doing a big Solar City solar install (12kW) without any storage capacity. I'll let PG&E 'store' my power gererated at mid-day and buy it back at night under a TOU meter (and set my MS to begin charging at 12 mn).

@rlarno

Stationary electricity storage could be a great use for degraded battery packs. I ddoubt it could ever be economically viable with a brand new pack, though. Also, transfering power from one battery to another will result in a loss of power, so you may want to limit that habit.

jp@jonathanposin.com hinted on a very relevant and interesting fact about solar power, that unless you are not connected to the grid, you will probably want to sell power from the panels because they produce when electricity demand and price is usually highest, and then you can buy power at night when the price is lower. Batteries wouldn't be useful on a daily basis except to charge them up at night from the grid and sell on the grid (or use the power yourself) during the day when TOU price is highest. Alternatively, if you need or want back up power, a battery back could be charged once and left alone until the day when you need the power because there is a black out.

I think that energy storage will not be viable anytime soon, but someday, especially with old, inexpensive battery packs from cars, locations that need back-up power (or cannot afford to be without power, like hospitals where people's lives depend on machines or data centers that must always remain on) will set up such systems and cycle power between TOU rates to generate revenue and cover part of the cost of the back-up power system. Elon and Solarcity will probably make it all work as soon as it's viable.
