ISDE subsidy for energy storage everything you need to know
The transition to renewable energy is in full swing. More and more companies and households are investing in solar panels, heat pumps and other sustainable installations. But one challenge remains how do you make optimal use of the energy you generate Energy storage for example with a battery provides the answer. The next question is often are subsidies available In this article you will read everything about the ISDE subsidy for energy storage, how the scheme works and what opportunities there are for different target groups.
What is the ISDE subsidy
The Investment subsidy for renewable energy and energy saving (ISDE) is a national scheme from the Netherlands Enterprise Agency RVO. This subsidy supports both companies and households in investing in sustainable technologies such as
- Heat pumps
- Solar boilers
- Insulation measures
- Connection to a heat network
In recent years it has also become possible to receive subsidies for energy storage in combination with solar panels or wind energy. The aim is to increase self consumption of renewable energy and reduce pressure on the electricity grid.

Why is energy storage important
Energy storage is becoming increasingly relevant now that the electricity grid in many regions is overloaded. With a battery you can
- Store surplus solar power for later use
- Limit feed in to the grid and avoid negative feed in tariffs
- Become more self sufficient and reduce peak demand
For companies and institutions energy storage can also contribute to lower energy bills and more control over energy costs. In addition energy storage plays an important role in the future of district heating which will change significantly from 2026. Read more in our blog what changes in district heating from 2026.
ISDE subsidy for energy storage the options
Although the ISDE is best known for heat pumps and insulation there are also opportunities for energy storage. Important to know
- Energy storage is often subsidized in combination with solar panels or a heat pump
- Separate budgets are available for business and private applications
- The subsidy amount depends on the type of installation capacity and application
A battery for solar panels can be eligible provided it meets the technical requirements of the scheme.
For whom is the ISDE subsidy relevant
1. Companies and institutions
Business users benefit from lower grid costs and a more stable energy supply. Especially with peak consumption a battery helps to reduce capacity tariffs. The ISDE makes the investment more feasible.
2.Households
Homeowners with solar panels increasingly find that feed in is less profitable. A home battery uses generated solar power to the maximum. With subsidy the payback period becomes more attractive.
3.Energy consultants and installers
The scheme provides an opportunity to convince customers of the benefits of energy storage. Subsidy lowers the entry barrier and enlarges the market.
How to apply for the ISDE subsidy
The application runs via the RVO website. The process generally looks like this
-
Check whether your installation and supplier are on the RVO code list.
-
Apply for the subsidy within 12 months of purchase and installation.
-
Provide the invoices and technical specifications.
-
The grant decision follows within a few weeks.
Note conditions differ per target group (business or private). For example companies often have to apply before purchasing while private individuals can also apply afterwards.

Future of energy storage and subsidies
It is expected that the role of energy storage in the Netherlands will only increase in the coming years. Due to grid congestion and the phase out of net metering the need is growing rapidly. It is likely that the government will continue to support these developments with schemes such as the ISDE or additional programs.
An important addition is good energy management. This helps organizations to make optimal use of their sustainable installations and storage. Read more in our article https://www.aurumeurope.com/en/blog/what-is-energy-management/
Frequently asked questions about ISDE subsidy for energy storage
Can I get a subsidy for a home battery without solar panels?
No the ISDE subsidy usually only applies in combination with solar panels or another sustainable installation.
How much subsidy do I get for a battery?
The amount differs per situation. It depends on the capacity of the battery the type of installation and your target group (private or business).
How long does it take before my ISDE application is processed?
RVO usually assesses applications within a few weeks. Make sure to provide complete invoices and technical information.
Is the ISDE subsidy for energy storage also available in 2026?
The ISDE will run at least until 2030. Exact conditions may change annually so it is wise to always check the current scheme.
Does energy storage have other benefits besides subsidy?
Yes in addition to financial benefits energy storage offers more independence from the electricity grid less grid congestion and lower CO₂ emissions.
