SCE = Southern California Edison, which isn't your utility as you are with SDG&E, San Diego Gas & Electric.The numbers provided by Tesla are lower than the actual. What is/are NBC/SCE?
The only sheet I know of is https://www.sdge.com/sites/default/files/regulatory/11-1-21 Schedule DR-SES Total Rates Table.pdf and don’t see anything matching those acronyms.
Yes I tried using your exact numbers and it didn’t work.
While not precise, we average close to 3kwh /hr of power usage (from all sources) during our peak period so 5 hours (4-9pm).
NBC = Non-Bypassable Charges which are the fees that you must pay for electric imports.
All of your Buy and Sell prices are equal with Peak at $0.30, Mid-Peak at $0.29 and Off-Peak at $0.28. The algorithm knows that with a 90% efficiency for the Powerwall recharge you will not benefit from discharging in either Peak or Mid-Peak and recharging during Off-Peak.
Now, the Buy vs Sell should have a difference for the NBC, so I would recommend increasing the Peak Buy prices by $0.04 to $0.34 and decrease the Off-Peak Sell price by $0.03 to $0.25 and see if that gets you want you want.
