What Exactly Is Changing?

By 2027, your Swedish electricity bill will consist of four mandatory components:

1. Fixed Fee: Based on your connection (e.g., your fuse size).
2. Customer-Specific Fee: For metering, calculation, and reporting.
3. Energy Charge: A price per kWh consumed (often time-differentiated: more expensive during the day, cheaper at night).
4. Effektavgift (Power Demand Charge): This is the major shift. You will be charged based on the amount of electricity you draw at a single point in time. The higher your peak demand, the higher your bill.

The Challenge: Preventing Peaks Without Sacrificing Comfort

The difficulty with the 'effektavgift' is that it is nearly impossible for a human to manually track whether the washing machine, heat pump, and EV charger are all running at the same time. A single hour of high demand can significantly inflate your grid costs for the entire month.

The Solution: SmartgridOne by Eniris

The SmartgridOne by Eniris is specifically designed to manage exactly this scenario. The system acts as an intelligent conductor for all electrical assets in a building:

• Real-time Peak Shaving: SmartgridOne constantly monitors the total power draw. If you are about to exceed a specific threshold (which would trigger a higher effektavgift), the system automatically dims the EV charger or briefly pauses the heat pump.
• Time-Differentiation Management: Since the new Swedish tariffs are time-sensitive (more expensive during 'höglasttid' or peak-load hours), SmartgridOne automatically shifts heavy consumption to off-peak hours without the user noticing.
• Integration with Dynamic Pricing: Beyond grid tariffs, Eniris also factors in hourly spot market prices. This allows for double savings: reducing the cost of the energy itself and the cost of the grid usage.

Full Automation: Instead of manually changing your behavior, you let technology do the work. The SmartgridOne reads signals from the grid operator and reacts faster than any human could.

The 2026 Figures: What Does a Peak Cost?

Let's look at the current 2026 rates from Ellevio. They use a model where the average of your three highest hourly peaks per month (measured on three different days) determines the price.

• Effektavgift (Daytime, 06:00–22:00): 81.25 SEK per kW.
• Effektavgift (Nighttime, 22:00–06:00): 40.63 SEK per kW (50% discount).

Calculation Example: The Unmanaged Villa

A typical villa in the Stockholm region charges its electric car (11 kW) while the heat pump kicks in (4 kW) and someone is cooking dinner (3 kW). This results in a peak of 18 kW.

• Without management, this customer pays this month: 18 kW × 81.25 SEK = 1,462.50 SEK in power demand charges alone.
