Flow Power bills using: Final Rate = Base Rate + PEA
PEA adjusts your rate based on when you consume relative to wholesale prices:
- Cheap wholesale (e.g. midday solar) → negative PEA → you pay less than the base rate
- Average wholesale → PEA near zero → you pay roughly the base rate
- Expensive wholesale (e.g. evening peak) → positive PEA → you pay more than the base rate
The PEA formula is: PEA = wholesale - TWAP - 1.7
Where:
- TWAP is the 30-day rolling Time Weighted Average Price (the market average)
- 1.7 c/kWh is the BPEA (Benchmark Performance Efficiency Adjustment)
PowerSync calculates the TWAP dynamically from actual wholesale prices. On a fresh install, it falls back to 8.0 c/kWh until enough data is collected (~1 hour / 12 samples).
| Sensor | Description |
|---|---|
| Flow Power Import Price | Current import rate in $/kWh (Base Rate + PEA) |
| Flow Power Export Price | Current export rate — Happy Hour rate during 5:30-7:30pm, 0 otherwise |
| Flow Power TWAP 30-Day Average | Rolling 30-day market average in c/kWh used in PEA calculation |
The TWAP sensor includes attributes: days_of_data, sample_count, using_fallback, and twap_dollars.
