A collective geothermal project intended to supply greenhouse growers in the Bommelerwaard has been stopped after developer Gaia Energy and regional partner Glastuinbouwpact Bommelerwaard concluded that the plan no longer had a robust, financeable business case.
The 4 October project notice says the decision followed several years of technical, geological and economic work. Independent Dutch agricultural outlet Nieuwe Oogst reported the same project stop on 5 October.
Subsidy rejection weakened the financing case
The project initially examined deep geothermal potential, but the regional partner said the deeper subsurface did not provide a technically feasible route. The team then investigated a shallower layer at roughly 500 metres and developed a concept for a collective heat system serving local greenhouse production.
According to the project notice, an SDE++ subsidy application was rejected because the concept would also recover heat from less than 500 metres depth. The separate SWiG subsidy for the associated heat network then also fell away. Gaia Energy and Glastuinbouwpact said that left insufficient financing certainty and no robust financially viable business case for continued development.
The exploration permit has expired
The permit for the exploration area has now expired, ending the current geothermal investigation in the Bommelerwaard. The partner notice does not identify a replacement collective heat project or an alternative financing route.
Gaia Energy’s own project page still describes the Bommelerwaard scheme as being in development and refers to an approximately 1,300-metre concept. Because that page conflicts with the newer 4 October termination notice, HortiSignal treats it as background rather than the current project status.
Why it matters for greenhouse operators
The cancellation removes one planned collective low-carbon heat route for growers in the region and highlights a financing risk in greenhouse energy infrastructure: projects can depend on several linked subsidy and network-investment decisions rather than on geology or engineering alone.
For operators evaluating future heat options, the next signal will be whether growers, the municipality or another developer bring forward a replacement collective system or a different decarbonisation route.
Key takeaways
- Gaia Energy has ended development of the collective Bommelerwaard geothermal project.
- The regional partner says an SDE++ rejection also caused planned SWiG support for the heat network to fall away, undermining financing certainty.
- The exploration permit has expired, and no replacement collective heat project is identified in the current source material.
