It raises self-consumption from solar
Electricity produced at midday can be used in the evening. That is the difference between replacing purchased electricity and selling it back cheaply.
All energy measures
On-site energy generation
Energy storage at home
Energy storage moves energy in time — either as electricity in a battery or as heat in a buffer tank. The value lies in the fact that production and consumption rarely coincide.
See what this means for your homeThis measure is relevant if
- You have solar panels and sell a lot back to the grid
- The capacity element of the grid tariff shows on the bill
- You have a solar collector or a wood stove with a water jacket
- Consumption is concentrated in a few hours
What it does to energy use
It shaves the peak
A battery can cover the highest hours, so the grid tariff's capacity element is calculated on a lower band.
Heat storage is cheaper than a battery
A buffer tank stores energy as heat at a fraction of the cost per kilowatt-hour, but can only return heat.
Storage has losses
Both batteries and tanks lose something along the way. The net gain is stored energy minus losses, not the whole amount.
Sequence matters
Storage comes last. It depends on there being something to store — solar panels, a collector or a heat source that runs in bursts — and on consumption being mapped, so the system is sized to actual peaks rather than to rules of thumb.
Enova funding
Enova has two schemes that touch this: buffer tanks for heat storage, and price- and load-controlled energy storage for the electrical version.
Rates and terms change. What you can receive depends on the building, how the work is carried out and which schemes apply at the time. Always check Enova's own pages before relying on a figure.
The rates tell you what you can receive. The calculation tells you what the measure actually does to your home — how much it saves, what it costs, and whether it should come before or after the others.
