1 h 45 min totalFrom forecasts to charging plans
- Generation forecast correction
- Compare past weather forecasts with measured generation to identify bias across weather conditions and refine next-day generation estimates.
- Load and forecast range
- Estimate day-ahead load in 15-minute intervals for metered circuits. The median curve shows a typical estimate and the P10–P90 band shows uncertainty.
- Grid charging window and energy
- The plan shows recommended charging periods and total charging time. Separate estimates for AC grid energy and energy reaching the battery make charging losses visible.
- Cost and backup reserves
- Compare candidate plans using time-of-use rates, charging efficiency, and battery wear, then check each plan against reserve requirements.
Typical use cases
Strong solar output on sunny days
When next-day generation is forecast to be high and load low, compare reduced grid charging with skipping it to balance backup reserves and solar utilization.
Cloud cover and high evening demand
When low solar generation and high evening demand are forecast, estimate the storage shortfall and compare early charging options during off-peak periods.
Volatile electricity demand
When the forecast band widens, check backup reserves under both typical and higher-load scenarios.
Metering boundaries and plan evaluation
- Define metering boundaries
- Track downstream demand, grid imports, and battery charge and discharge separately. This keeps battery charging out of the load forecast and prevents double-counting metered loads.
- Replay with information available at the time
- Preserve the forecasts available when the plan was made. Compare them with measurements for the same time intervals to quantify generation and load forecast errors.
- Compare plans under the same conditions
- Compare fixed-window charging, no grid charging, and the recommended plan against the same historical interval. Evaluate estimated costs and backup reserves. The dashboard illustrates what the plan reports.
