Recent shifts in Dutch gas infrastructure law
In the past two calendar years, Netherlands gas infrastructure laws have moved from "maintain the gas grid" to "manage its phased replacement," with three core changes dominating the new landscape: the legal freeze on almost all new gas connections, the formalisation of Green Gas Blending Obligation rules, and the transfer of last-mile gas-disconnection powers to municipal authorities. These changes are codified mainly in the updated Energy Act, the Municipal Heat Transition Instruments Act, and the 2025 Green Gas Blending Obligation Act, which together redefine how gas is supplied, stored, and eventually phased out in the Dutch system.
For the general public and utilities, the most visible impact is that new residential construction can no longer hook into the low-pressure gas grid in most of the country, and existing users in designated heat transition zones can now be legally disconnected in favour of district heating or all-electric systems. Behind the scenes, the Transmission System Operator (TSO) Gasunie and its subsidiary GTS remain responsible for gas security of supply while the system shrinks, but they must now plan for decline rather than growth in demand.
Core legal updates since 2024
Since 2024, the Netherlands has enacted a series of amendments and new acts that touch almost every tier of the gas value chain: exploration and production, transmission, storage, distribution, and end-use. The Mining Act has been tightened to clarify decommissioning requirements for offshore pipelines and wells, while the Gas Act and the broader Energy Act framework now treat the gas grid as a temporary backbone rather than a permanent fixture.
Under the amended Energy Act of 2025 and its 2026 implementing decrees, gas transmission and distribution remain subject to strict unbundling rules, but the mandate to "guarantee widespread service" has been quietly replaced with obligations to "ensure orderly transition" and "manage decline safely." GTS still submits an annual security of supply overview for each gas year and must demonstrate that storage, LNG-import capacity, and interconnectors with Germany and Belgium can meet residual demand, even if the country as a whole moves toward all-electric heating.
Key changes to grid access and connection rights
Perhaps the most consequential shift for consumers and developers is the effective end of automatic gas connection rights for new buildings. Under the Heat Act as amended in 2024 and the Municipal Heat Transition Instruments Act of 2025, municipalities can designate heat transition neighbourhoods where gas supply is no longer considered a default service.
In those areas, local authorities may require new construction to be all-electric or connected to district heating networks, while existing gas customers can be disconnected once the municipality's transition plan is approved. The law also preserves the right to a gas connection only for buildings completed before 1 July 2018, and even this safety net is gradually being phased out in transition zones.
Green Gas Blending and decarbonisation duties
Complementing the grid-access changes, the 2025 Green Gas Blending Obligation Act imposes annual ratcheting targets for renewable gas in the pipeline system. The law requires licensed gas suppliers to blend a rising share of biogas and other renewable gases into the national gas network volumes, with 2026 targets set at roughly 14% green gas by energy content, rising to about 25% by 2030.
From a legal perspective, this means that gas suppliers must either procure certified green gas certificates or directly invest in biogas production and upgrading infrastructure. The Energy Act now ties these obligations to the licence condition that distribution companies must "support the energy transition," giving regulators a direct hook to sanction non-compliance.
Storage, LNG, and security-of-supply re-calibration
While the grid is shrinking, Dutch gas infrastructure law still places strong emphasis on gas storage capacity and import flexibility. The Gas Act continues to require the TSO to maintain sufficient storage levels to ensure security of supply, but the benchmarks are now calculated against a declining demand curve.
For the 2026-2027 gas year, GTS has set a minimum storage fill target of approximately 115 terawatt-hours (TWh), or about 11.5 billion cubic meters (bcm), assuming a cold winter and a high reliance on imported LNG supplies. The law also requires that interconnection capacity with neighbouring countries be kept at levels sufficient to import this gas if domestic production falters or storage runs low.
Local powers and heat-transition instruments
The 2025 Municipal Heat Transition Instruments Act is the most visible legal shift in how gas infrastructure is governed at street level. The law gives municipalities the authority to designate heat transition areas, where they can decide that gas will no longer be supplied and that residents must switch to district heating, all-electric systems, or other approved alternatives.
Municipal authorities must also ensure that any replacement heat infrastructure is placed under public control or at least subject to a controlling majority of public ownership. This requirement is designed to prevent private monopolies from taking over the same neighbourhoods once the gas grid is dismantled.
Market structure and unbundling reforms
On the institutional side, Dutch gas infrastructure law continues to enforce strict unbundling between gas transportation and commercial activities. The Gas Act and Energy Act both enshrine a "group ban" that prevents network managers from sharing corporate parents with gas producers or retailers, a rule that now extends to cross-border interconnectors and LNG-terminal operators as well.
In 2026, these rules were tightened further to close minor loopholes involving joint-venture arrangements and minority shareholdings. Regulators now require that transmission and distribution functions be organisationally and financially separate, with distinct boards and risk-management frameworks.
Illustrative timeline of key changes
- 2022-2023: National ban on gas connections for new residential buildings enters force, setting the stage for broader curbs on gas grid expansion.
- 2024: The Heat Act is amended, and pilot municipal gas-disconnection powers are tested in several cities.
- 2025: The Municipal Heat Transition Instruments Act and the Green Gas Blending Obligation Act are formally adopted, embedding transition and decarbonisation mandates into gas-infrastructure law.
- 2025-2026: The updated Energy Act and implementing decrees redefine security-of-supply targets around a declining gas-demand scenario.
- 2026: National regulators begin enforcing stricter unbundling and M&A-screening rules for gas-related infrastructure assets.
Entities and obligations under the new regime
- Transmission System Operators (e.g., Gasunie, GTS): Responsible for maintaining adequate storage levels, managing interconnectors, and submitting annual security of supply overviews to the Ministry of Climate Policy and Green Growth.
- Gas distribution companies: Must comply with unbundling rules, support heat-transition projects in their service areas, and meet evolving green-gas blending obligations.
- Municipal authorities: Can designate heat transition neighbourhoods, manage local disconnection processes, and oversee the development of public-owned heat infrastructure.
- Gas suppliers: Must meet the annual green-gas blending targets, secure traceable green gas certificates, and provide transparent information to consumers about the share of renewables in their gas mix.
Impact table: before vs. after 2024-2025 reforms
| Policy area | Before 2024 | After 2024-2025 reforms |
|---|---|---|
| New gas connections | Most new residential buildings could still be connected to the gas grid, subject only to local technical feasibility. | Almost all new residential construction is effectively barred from gas; only pre-2018 buildings in non-transition areas may retain connection rights. |
| Municipal powers | Municipalities had limited authority to override individual gas-connection rights. | Municipalities can now designate heat transition areas and legally disconnect gas users once alternative heating is in place. |
| Green gas content | Voluntary or lightly incentivised blending of renewable gas into the national pipeline system. | Strict annual green gas blending targets (14% in 2026, rising to 25% by 2030) backed by license-condition enforcement. |
| Security of supply focus | Security of supply was framed around maintaining or expanding gas infrastructure to meet expected demand. | Security of supply is now defined in relation to a shrinking but still significant residual gas demand, with explicit plans for managed decline. |
| Unbundling rules | Separation existed mainly at the transmission level, with some grandfathering of integrated structures. | Full ownership unbundling and tighter restrictions on cross-border joint ventures and minority stakes in gas network managers. |
FAQs on recent Dutch gas infrastructure law changes
Key concerns and solutions for Netherlands Gas Infrastructure Laws Spark Debate Who Wins
Which customers can still get a gas connection in 2026?
Under current Dutch law, customers can still obtain a gas connection only if they meet all three conditions: the building was completed before 1 July 2018, it is located outside a designated heat transition neighbourhood, and the municipality has not yet adopted a binding local heat plan. In practice, more than 60% of municipalities now have some form of heat plan or transition area, sharply limiting where new gas hookups remain possible.
What counts as "green gas" under the new law?
Under the Green Gas Blending Obligation Act, "green gas" includes biomethane produced from organic waste, wastewater sludge, agricultural residues, and certain industrial by-products, provided it meets specified methane-content and carbon-intensity thresholds. Biogas must be upgraded to grid-quality specifications and accompanied by traceability certificates issued by the Dutch Emissions Authority (NEa) to be counted toward the blending targets.
How is "security of supply" now defined in Dutch law?
Post-2024, the Dutch legal definition of gas security of supply includes four components: adequate domestic and imported gas volumes, sufficient storage to bridge winter peaks, robust interconnectors with at least two neighbouring countries, and credible contingency plans approved by the Ministry of Climate Policy and Green Growth. If any of these pillars is materially weakened, the TSO must propose corrective measures or risk being ordered to upgrade infrastructure.
What checks exist on municipal gas-disconnection powers?
Under the Municipal Heat Transition Instruments Act, municipalities cannot disconnect gas users without first publishing a detailed heat transition plan and holding a public consultation. The plan must be approved by the provincial authority and, in some cases, the national government, and must demonstrate that adequate alternative heating (such as district heating or heat pumps) is available at comparable cost.
Are new homes still allowed to connect to the gas grid?
Under current Netherlands gas infrastructure laws, new homes generally cannot obtain a gas connection, except in rare cases where a municipality has not yet adopted a heat transition plan and the building was completed before 1 July 2018. Even in those situations, local authorities are increasingly steering developers toward district heating or all-electric designs.
Can my existing gas connection be legally removed?
Yes. If your property is located in a formally designated heat transition neighbourhood, the municipality can legally disconnect your gas supply once an approved heat-transition plan is in place and adequate alternative heating (such as district heating or heat-pump-based systems) is available. The plan must survive a public consultation and government-level scrutiny before orders to disconnect can be issued.
What does the Green Gas Blending Obligation mean for my gas bill?
The Green Gas Blending Obligation Act requires suppliers to mix a growing share of renewable gas into the pipeline system, which can slightly increase procurement and certificate-costs for licensed companies. In practice, these costs are typically passed on in tariffs, but the law also mandates that suppliers provide clear information about the green gas share on bills and websites so consumers can compare offers.
How does the government ensure gas still reaches essential users during the transition?
Netherlands gas infrastructure law still requires the Transmission System Operator to maintain sufficient gas storage capacity and interconnection links to meet residual demand, especially in a cold winter. For the 2026-2027 gas year, GTS estimates that about 115 TWh of storage plus LNG-import capacity will be needed to cover remaining industrial and critical-infrastructure users while the rest of the system shifts to alternatives.
What role do municipalities play in shaping local gas infrastructure?
Under the Municipal Heat Transition Instruments Act, municipalities can now decide whether gas remains supplied in specific heat transition areas, set the pace of disconnections, and ensure that replacement heat networks are publicly controlled or at least under strong public oversight. This gives cities a central role in designing the post-gas landscape without entirely losing the backing of national security of supply frameworks.
