PVO updates tariffs as often as the user enters them. It is manual. It doesn't support any type of tiering / baseline credit, just straight hourly bins and price associated for each. It is flexible enough to handle each day of the week and holidays separately, if needed, and the appropriate holidays are manually entered (by calendar data, not name).
Once the credit/cost on a particular date has been calculated, is stays stored that way even if the user subsequently changes the tariff. Historical data can be marked for recalculation under the new tariff if the user chooses.
It works well for the current incarnations of DR-SES and EV-TOU-2, but with the future of TOU looking likely to have a baseline allocation at some point, the utility of PVO for this will diminish unless their developers opt to support more complicated rate plans.
I can see tariffs getting quite a bit more complicated and even less transparent than they already are in the future. This in spite of one of the AB 327 mandates being greater billing and tariff transparency.
