The problem

The funding is there. Timing and sequence decide how you get it.

With some programmes you apply only after commissioning; with others you may not commission any supplier before the approval notice.

Your 3 funding options

Three funding routes for storage and networks.

We check which one fits your project — and submit the application in the right programme.

KWKG

Buffer storage under the KWKG

Up to €250/m³, max. 30% of investment costs (storage costs only).

Commission first, then apply by 1 July — immediate ordering possible.

BEW

Buffer storage & heating network under the BEW

Federal Funding for Efficient Heating Networks

40% of investment costs.

(Almost) every component eligible — including the transfer station and planning.

KWKG

Cooling & heating networks under the KWKG

40% of investment costs, funded up to the transfer station.

Commission first, then apply by 1 July — immediate ordering possible.

Cut-off date for heat storage and heating networks under the KWKG: if the storage is only commissioned after 31 Dec 2026, KWKG funding is only retained if the permits required under state law have been obtained by then — or, if none are required, the essential construction work has been bindingly commissioned.KWKG amendment ahead: in September 2026 the German Federal Ministry for Economic Affairs presented a key-points paper on amending the KWKG. The amendment is to come into force by the first quarter of 2027 at the latest. Among other things, it provides for funding heating networks and heat storage commissioned by the end of 2035, higher funding caps and a ban on combining it with other federal investment grants. No transitional arrangements are planned so far. It is only a key-points paper; details may still change (as of October 2026). So talk to us early about your timeline.

Honest pre-selection

Are we a good fit?

We say openly what we are the right partner for — and what we are not. That saves you time.

We're the right partner if …

you are investing in heat storage or a heating network with your biogas plant or as a business.

you want to hand over the entire application process — from the check to the submitted application.

you want to know in advance which funding route is right for your project.

Probably not the right fit if …

you are looking for funding for a private home — the residential building programmes and your local energy consultant are the better choice for that.

the application deadline for your storage has already passed (application by 1 July of the year following commissioning).

you just want a quick funding commitment via a form — a serious check needs the real project data.

More funding

Also investing in plant efficiency or a development?

Alongside storage and heating networks, we know the programmes for biogas, energy efficiency (EEW) and the research allowance — from over 750 supported applications.

Next step

Call us — we'll explain the process in 10 minutes.

Your initial check is free of charge: you find out without obligation which funding route is possible for your project. For heat storage, 31 Dec 2026 is the key date — by then your permits should be in place or the construction work commissioned.
