Reserve Market Guide
Battery storage can sell its capacity to Fingrid's reserve markets, generating annual returns regardless of your electricity consumption. This guide covers markets, systems, required steps, and an honest calculation example.

Demand Charge Guide
Demand charges are based on your highest average power demand in a month, not on total energy consumed. This guide explains how peaks occur, how they are metered and how battery storage effectively cuts them.

Farm Energy Storage Guide
On a farm, electricity consumption is concentrated into short, intense peaks, and a power cut can bring operations to a standstill. This guide explains how battery storage fits into daily farm operations and which figures matter most.

How much does a home battery save?
The profitability of a home battery should not be assessed on purchase price alone. What matters is the total benefit: how much the battery reduces electricity purchases during expensive hours and how much it earns in the Emaldo Grid Rewards programme.

Is a home battery worthwhile for a detached house?
A home battery is especially worthwhile when using spot electricity, consumption is high, or the home has solar panels. Here is how to identify whether a battery is right for your home.

Home battery or solar panels first?
Solar panels generate electricity during the day; a battery shifts it to the evening. Which one you should get first depends on what drives your electricity bill.

Backup power for power cuts
You can prepare for power cuts with a portable power station or a whole-home battery. The choice depends on which appliances you want to keep running and for how long.
