Peak shaving and power peaks: lower grid costs with ENEQUI's AI-powered battery control.
The solution adapts to your bidding zone and DSO tariff, whether the home is in Stockholm, Gothenburg, Malmö, Linköping or outside urban areas.
Peak shaving means keeping grid import power below a tariff-critical level when it matters most. In many Swedish networks, power is measured as a 15-minute average. The highest quarter in the month often drives the capacity charge, even if the spike lasted only a few minutes.
That is separate from the per-kWh energy price from retail. You can buy cheap energy from Nord Pool one hour and still face an expensive month if the peak at dinner and car charging lands high. Combining hourly optimization with active peak control pays off.
For homeowners in places like Mölndal, Västerås or Helsingborg the numbers differ, but the mechanism is the same: lower the month's highest quarter-hour average and the capacity charge often drops.
ENEQUI Core sees the whole picture: inverter, battery, heating and charger in one real-time view.
When quarter-hour average power approaches the month's high, storage can deliver power so grid import flattens. A typical 10–15 kWh home battery can deliver 5–10 kW briefly, often enough to clip the worst spike when heat pump and kitchen start together.
Heat pump, hot water and other flexible loads can move a few hours when spot in your zone (SE1–SE4) is lower and the home still risks a high quarter-hour average. That cuts both energy cost and the chance of an expensive quarter coinciding with high concurrency.
EV charging is often 3.7–11 kW continuous load. Core can briefly reduce or pause charging when other equipment pushes power, then resume when the quarter window is safe. The same logic avoids battery discharge to grid colliding with max car charging in the same quarter.
Assume a villa that without control hits 19 kW as the highest quarter-hour average one cold February week when car and heat pump run together. After ENEQUI Core and a 12 kWh battery, the curve flattens so the monthly peak lands at 15 kW. That is 4 kW lower registered capacity.
If the DSO model in this example charges roughly 45–70 SEK per kW per month for the capacity component, 4 kW is about 2,200–3,400 SEK less per year on that line alone, before hourly Nord Pool gains. Your tariff may differ; the exact level is always in the DSO price sheet.
On a volatile winter day the gap between cheapest and most expensive hour in the same zone can exceed 2–4 SEK/kWh. When Core also moves a few kWh from an expensive hour to a cheap one, savings grow beyond the capacity charge.
Peak shaving means actively lowering short power peaks so the month's highest average import power is lower. Many DSOs base part of the grid fee on the highest 15-minute average during the billing month. The lower that peak, the lower the capacity charge often is for the year.
Peaks are short moments when car, heat pump, sauna and battery discharge coincide. The DSO often uses the highest quarter-hour average in the month as the basis for a capacity-related line item. Shifting a few kilowatts in the right minutes can therefore change the whole month's level.
Yes. Control stays within limits you set for temperature, EV ready time and battery state of charge. Core often shifts only a few minutes of charging or briefly caps EV power when the home would otherwise cross an expensive quarter-hour average.
The principle is the same, but numbers follow your DSO tariff sheet and your actual site. Urban areas often have higher concurrent load per dwelling, while homes outside Uppsala or Jönköping can show different peak patterns. ENEQUI uses your real curve, not a generic city model.
In Smart Saver, savings can often be tracked by mechanism when data allows, for example peak shaving versus hourly price optimization. Core handles real-time control toward the inverter and charger; Smart Saver makes the economics visible for the household.
