I am on NEM 1.0 so cant tell you exactly how it will look for you. I would imagine the basics are the same, though. If you are a net producer for the month, you bet billed for the bace charges (non bypassable charges, or base charges for being connected). In my case that is about $10 -$11. If I am a net consumer for the month, because NEM has almost no NBCs, I only pay about $1.50 or so with the rest going to the true up total.
Because I have my "SCE year" start in march, I always start with negative numbers (or said another way, I am a net producer from march till about october every year), so I always have a credit on my account when I get to the colder months when I dont produce enough solar to cover it. So from march to october when I am a net producer I pay $10-11 a month. From November to Feb I pay $1.50 a month and the consumption goes against the credit on my account.
Last year (2019) when I drove 18k miles with my model 3, my true up bill was $200. Before that, I always had a negative number at true up, which ended up getting paid at wholesale rates. I expect to break even this year, because I drive a lot less, but got a TV thats twice as power hungry as my last one, and it sees a lot of use.
Should be the same structure for you, just different amounts because you wont be on NEM 1 and will have non bypassable charges I dont have.
