Guaranteed Grid Rewards gives you a fixed monthly payment. It is open to new Emaldo® systems that your installer commissioned on or after 6 September 2026, in Denmark, Sweden, Finland and the Netherlands. The contract runs for 3 years.
You can't join Guaranteed Grid Rewards directly. First you sign up for Flexible Grid Rewards in the Emaldo® app, then you apply here to switch.
Sign up for Flexible Grid Rewards within 30 days. You must sign up in the app no later than 30 days after your installer has linked the system to your Emaldo® app, and then apply here. After that, your system can no longer join Guaranteed Grid Rewards.
Apply for Guaranteed Grid Rewards
Before you apply
Check that your system meets all of these requirements. When you switch in the app, the app checks them before you can sign.
- You have a new Emaldo® system with at least three batteries. One Emaldo® unit with at least three 5.12 kWh batteries. Adding batteries to an older system does not make it eligible. If you have more than one Emaldo® unit, Guaranteed Grid Rewards is based on the unit with the most batteries.
- Your system is online. The Emaldo® app shows live information from your system. What to do if your system is offline
- You have signed up for Flexible Grid Rewards in the app. This is the first step before you can switch. How to sign up for Flexible Grid Rewards
- Your system is in AI Mode. AI Mode is turned on when you join Flexible Grid Rewards. Grid Rewards does not work in Schedule Mode. How to turn on AI Mode
- You have entered both meter IDs in the app. You need your Consumption ID and your Production ID (the app may call them Meter ID or Facility ID). Each has 18 digits. Your Consumption ID is usually on your electricity bill, and your installer can give you the Production ID. Check both carefully before you save them: you can't change them yourself afterwards. How to add your meter IDs in the app
- You have an eligible electricity supplier. Your supplier's tier sets your monthly payment. Check your supplier and payment level
- Peak Shaving is off, or set to at least 6.1 kW. Peak Shaving is off by default, and most customers don't need it. If you have turned it on, set the Power Peak to 6.1 kW or higher. How to set up Peak Shaving
- Your system is working normally. There must be no hardware faults, missing meter IDs or communication problems. Check the Grid Rewards widget in the app for reported issues before you apply. About the Grid Rewards widget
You'll need your device ID for the application. If you have more than one unit, use the ID of the unit with the most batteries. Where to find your device ID
What happens after you apply
- We check your application. We check the dates in your application and then ask our technical team to enable the switch for your system. This happens once a week, so it usually takes up to a week. You get an e-mail when you have applied, and again when you can switch.
- You complete the switch in the app. As soon as the switch is enabled, you switch yourself in the Emaldo® app and sign a new agreement. Before you can sign, the app checks the requirements above. After you sign, the change takes up to 15 days, and in that time the app may show the wrong payout level. How to switch in the app
- Your system completes prequalification. The grid operator requires Emaldo® to show that your battery can deliver the capacity we promise. This takes three full calendar months, counted from the date you signed the Flexible Grid Rewards contract in the app. Your system starts earning no later than the first day of the fourth full calendar month.
- You receive your payments. We pay your earnings into your bank account every month, for the month before. Payments are made on the 24th, or the next business day, and can take up to five banking days to reach your account. When will my payout arrive?
Example: you sign up for Flexible Grid Rewards on 25 January
| What happens | When |
|---|---|
| Your Flexible Grid Rewards contract starts | 25 January |
| Three full calendar months of prequalification | February, March and April |
| Your system starts earning | No later than 1 May |
