Batería doméstica Subvenciones 2026: All Grants at a Glance

Overview: how much subvención can you get in 2026?

Anyone purchasing a batería doméstica in 2026 can benefit from an attractive package of subvenciones and tax advantages. The total financial support can amount to €3,000 or more, depending on the type of system and the municipality where you live. In this article, we discuss all current schemes in detail, so you know exactly what you can claim.

The urgency is significant: the compensación neta scheme ends on 1 January 2027. Those who invest now combine maximum subvenciones with the remaining compensación neta period. This significantly accelerates the payback period — sometimes from 8 years to 4-5 years.

1. ISDE subvención: the main national scheme

The Investment Subvención for Sustainable Energy (ISDE) is the largest national subvención scheme for baterías domésticas. In 2026, you can receive a contribution of €500 to €1,500 per sistema de batería doméstica through the ISDE, depending on capacity and installation type.

ISDE application procedure

The ISDE is applied for through the RVO (Países Bajos Enterprise Agency). You apply for the subvención after the battery has been installed. Always keep your invoice and installation certificate. The application is fully digital via rvo.nl and is typically processed within 8 weeks.

ISDE conditions for baterías domésticas

To qualify for the ISDE, the following conditions apply:

• The battery must be on the RVO list of approved products (HES products are listed)
• The system must be installed by a instalador certificado (for high-voltage systems)
• The battery must have a minimum of 1 kWh capacidad utilizable
• The application must be submitted within 3 months of installation

Subvenciones by system type: comparison table

Available subvenciones vary considerably by sistema de batería doméstica type. Below is an overview of the most popular systems and the corresponding schemes:

2. IVA benefit: 0% on the full installation

In addition to the ISDE, you benefit from the 0% IVA rate on baterías domésticas combined with paneles solares. This applies to homeowners with a property less than 10 years old and for combinations with newly installed paneles solares. The IVA benefit averages €199 to €600 on the battery itself.

When does 0% IVA apply?

The 0% IVA rate applies when the batería doméstica is installed together with paneles solares, or when you add the battery to an existing panel solar system at a property less than 10 years old. The installer automatically charges 0% IVA — no separate application is required.

Provincial and municipal subvenciones

On top of the national schemes, many provinces and municipalities offer their own subvenciones. Noord-Holland, Zuid-Holland and Noord-Brabant have active programmes with contributions of €200 to €750 per hogar. Always check the subvención guide for your own municipality or province via the RVO subvención guide.

Combining subvenciones smartly: maximum benefit

It is possible to utilise multiple schemes simultaneously. A smartly combined package can look as follows:

• ISDE subvención: €600 – €1,100
• 0% IVA benefit: €199 – €520
• Provincial subvención: €200 – €750
• Municipal scheme: €0 – €500

Energy tax reduction and compensación neta: until 2027

As long as the compensación neta scheme is still in place (until 1 January 2027), electricity inyectado to the grid still earns you a tax reduction through compensación neta. A batería doméstica maximises this benefit because you consume more solar power yourself instead of feeding it back at a lower rate.

After 2027, the system changes: you will then receive a tarifa de inyección that is on average 50-70% lower than the standard electricity rate. Those who invest now benefit from both the compensación neta advantage and the available subvenciones.

Step by step: applying for subvenciones

Follow these steps to apply for all subvenciones correctly and on time:

• Step 1: Choose a certified HES system and get advice on eligible products
• Step 2: Have the battery installed by a instalador certificado and keep all documentation
• Step 3: Submit the ISDE application via rvo.nl within 3 months of installation and apply for provincial/municipal subvenciones separately
