The Netherlands has widened subsidy treatment for heat storage and heat-delivery equipment in greenhouse heat networks. The SWiG amendments took effect on 1 October 2026, ahead of a €42 million round scheduled to open on 2 November.
The regulation published on 22 September changes which infrastructure components can receive support. This is a change to the scheme, not an announcement of new project awards or completed greenhouse connections.
Storage support no longer faces the mixed-use reduction
Heat storage used mainly for greenhouse horticulture will no longer face a 50% subsidy reduction when a small share also serves buildings. The change concerns the treatment of that component; it does not double support for the entire network.
Ownership determines delivery-equipment treatment
Qualifying heat-delivery equipment, known in Dutch as a warmte-afleverset or WAS, can now be included when the heat company builds and owns it. Grower-owned equipment remains excluded from this route.
Glastuinbouw Nederland’s 23 September explanation identifies less dependence on separate subsidy schemes as the practical benefit. Developers and growers therefore need to distinguish ownership of the delivery equipment from ownership of the greenhouse itself.
Application timing still needs clarification
The RVO programme page and the published regulation agree on the €42 million budget and November opening, but give different March 2027 closing dates. No official clarification was found in the sources checked on 6 October.
The verified business change is broader treatment of storage and delivery equipment. A reliable closing deadline remains unresolved, so these confirmed amendments do not provide a complete application timetable.
Key takeaways
- The amendments took effect on 1 October.
- Storage treatment broadens, while delivery-equipment eligibility depends on ownership.
- The next round is planned for November; its closing deadline still needs official clarification.
