Thankfully they did not get this passed.

As for a battery back up, AeroVironment is working on one, although not specific to solar, I do like the idea of charging at 120 to charge the car later at 240.

That is an interesting idea, and parallels the discussions about how to build a quick charger without incurring the demand charges. There's one little thing missing from the specs, though. How much does it hold?

If they are foresighted, they will also make a unit that's just the electronics, which you attach to the 10-year-old half-toasted EV battery you got back when you replaced the one in the car.
And there goes the first capacity bar! At 24,000 mi on 9/9/2013.
Second bar at 30,500 mi on 2/7/2015.

Very cool!


I can now stop wasting time finding a cost effective way to go off-grid!!!!

I can hardly wait for their next "idea".

This is great news! The PUC did the right thing. I see no way SDG&E could craft an alternate tariff which wouldn't single out solar producers.

The quote below isn't true. There's a minimum $0.17 per day, $62.05 per year charge to connect to the grid.

"Commissioner Ferron acknowledged the issue we are trying to address with our proposal is much broader than a single utility," said Lee Schavrien, senior vice president of finance, regulatory and legislative affairs for SDG&E, in a written statement. "The current net energy metering structure can easily result in many customers who have rooftop solar paying no bill at all, yet having access to all of the reliability, storage and access features of the grid. This is a situation that is not sustainable and requires a broad set of stakeholders to collaborate on a fair and effective solution."

Well, as long as SDG&E believes that solar customers are getting an unfair benefit from PV, they have to single out solar producers to do it. Reading the fine print and comparing the costs to what they normally charge, it could have been a lot worse.

The best way to avoid this is to make sure you always draw a net $65.05 worth of energy from the grid - at current rates of ~$0.14 / kWh on the DR rate, that comes to approximately 464 kWh. Then you will still pay the $62.05 / year, but at least you'll be getting energy for it.

I believe it resets monthly. So you couldn't bank any extra kWh for the month. You would need to use it all plus an additional $5 worth.

Re: SDG&E asks for higher rates on customers who go solar

SDG&E just credited me with 3.6¢ per kWh for my year's excess generation.

Of course, my excess at Peak Times flows 100 or 200 feet to the next door neighbor, who is charged something like 33¢ per kWh for the same electrons.

And, SDG&E is complaining that they do not make enough money from me. They have the $5+ a month "minimum", and make money on the 4 (or more) months that I do not over-generate.

Like the post office, they might just raise their charges enough to force "everybody" to go solar. Then, if they do not adapt, they might actually have some difficulty controlling their grid.

Seems pretty clear that the proposed distribution fee is contrary to state law. No idea why SDG&E thinks this is OK.
This is the provision cited as most relevant by the Commissioner when denying SDG&E the right to proceed with its rate request based on the NUC. The Commissioner also cited the preceding sentence of section (g) which states that all chargers must be based on net kWh. That works but it would seem that the more determinative section would be section (b), which lays out that every kWh generated must be valued the same as every kWh consumed, precluding SDG&E's proposal that a kWh consumed should be valued by adding an interconnection fee and that an an exported kWh be valued by subtracting an interconnection fee. IOW (5+1) would not equal (5-1).

Note that SDG&E can appeal, presumably to the whole commission. That would be a good thing since its argument is so weak and the question would be answered once and for all. But I suspect that SDG&E, along with the other utilities, will decide to fight this fight some other time when perhaps the commission is more receptive. My guess is that it hoped to get into a rate case and then just confuse things so that this issue didn't rise to the forefront. With that hope gone all it's left with is a very stinko legal argument.

Well, SDG&E did announce Tuesday that they have submitted 2 plans to buy solar power from them.

"SunRate" is similar to your typical green power plan where you pay a bit more to directly purchase solar power. You will have the option to offset 50%, 75% or 100% of your energy use with solar power at a fixed rate for 1-15 years. The fixed rate deal is pretty unique.

"Share the Sun" is a type of community solar program. Here you buy or lease shares in larger solar development projects and then your bill will be offset through a feed-in-tariff based on how much your portion of the project generates.

SoCal and solar rates are an interesting parallel to my area (Brentwood, TN). Once a habitation is connected to the grid and an electric meter is installed, it cannot be "removed from the grid". Similar in the rules for personal water wells. Our water table here is so high that you can stick a straw in the ground and have water; Once connected to Brentwood Water you may not "disconnect" from public water supply. You can not use the public water but you still pay since the sewerage fees are tied to the water consumption rate. I'm not sure how they treat folks who have a septic system and a water well and are not, have never been, connected to the city utilities. They are probably skating by until the local law can figure something out.
