If you have a renewable or storage project awarded in a just transition hub—linked to the closure of a thermal or nuclear power plant—this resolution changes the rules of the game from today. The Council of Ministers, through Agreement of July 28, 2026 published in the BOE on September 7, 2026, declares these projects "strategic energy installations" and applies the "preferred energy projects" regime to them.
The advantage is clear: administrative deadlines are significantly shortened. The cost is also concrete: a payment of 3% of the execution budget to the corresponding municipality before driving the first stake.
What does this regulation establish?
The Council of Ministers Agreement of July 28, 2026 declares "strategic energy installations" to renewable generation and energy storage projects that meet two simultaneous conditions:
- Having been awarded in the procedures for granting evacuation access capacity regulated in the twenty-second additional provision of Law 24/2013, on the Electricity Sector.
- Being located in just transition hubs, that is, in areas linked to the closure of thermal or nuclear power plants.
This declaration automatically activates the "preferred energy projects" regime, which implies:
| Area | What changes |
|---|---|
| Administrative authorizations | Urgent processing in the public interest |
| Environmental assessment | Urgent processing in the public interest |
| Administrative remedies | Urgent processing in the public interest |
| Urban planning fit | Public works of general interest regime applies |
| Environmental guarantees | No reduction: only deadlines are expedited, not substantive requirements |
| Payment to municipalities | 3% of execution budget, before start of works |
| Social commitments | Employment, training and business development in the affected territories |
A relevant nuance for promoters: environmental guarantees and substantive requirements are not reduced. The regulation only accelerates administrative deadlines, it does not eliminate or relax substantive requirements.
Economic and operational impact
The most direct and quantifiable impact is the payment of 3% of the execution budget to the municipality before the start of works. This amount is non-negotiable and non-deferrable: it is a prerequisite for the start of construction.
To put it in perspective: a medium-sized wind or solar park in a just transition zone may have execution budgets ranging from 20 to 80 million euros. The 3% represents between €600,000 and €2.4 million in advance payment to the municipality, with no direct return for the promoter.
On the positive side, urgent processing has real economic value: each month saved in authorizations reduces financial costs, technical personnel and guarantee maintenance costs. In projects of this magnitude, shortening the process by six or twelve months can result in savings exceeding the cost of the 3% itself.
Operationally, promoters must also assume formal commitments for employment, training and business development in the affected territories. These commitments must be articulated before the start of works and form part of the conditions of the strategic declaration.
Who does it affect?
- Promoters of renewable generation projects (wind, solar photovoltaic, etc.) awarded access capacity in just transition hubs.
- Promoters of energy storage projects under the same conditions.
- Legal and technical advisors managing authorizations for these projects: must adapt their procedures to the new urgent processing regime.
- Municipalities in just transition zones: recipients of 3% of the execution budget before the start of works.
- CFOs and financial directors of renewable promoters: must provision the 3% payment in the project treasury planning prior to the start of works.
- Sustainability and CSR departments: employment and local training commitments must be formalized and integrated into the project strategy.
Practical example
A renewable promoter has been awarded access capacity in a just transition hub linked to the closure of a coal-fired power plant. Its solar photovoltaic project has an execution budget of 40 million euros.
With the new declaration of strategic energy installation, the company benefits from urgent processing in all its authorizations and environmental impact assessment. However, before starting works it must:
- Pay to the corresponding municipality 3% of €40M = €1,200,000.
- Formalize employment, training and business development commitments in the affected area.
- Process urban planning fit under the public works of general interest regime.
In return, its authorization and environmental assessment files are processed urgently, which can significantly reduce deadlines compared to a conventional project. If the time savings equals 8 months of financial and management costs, the net balance can be favorable even after discounting the €1.2M payment to the municipality.
What should companies do now?
- Verify if your project is in a just transition hub and if you have been awarded access capacity under the twenty-second additional provision of Law 24/2013. If so, the strategic declaration applies to you from September 7, 2026.
- Provision the 3% of the execution budget in the project treasury plan. This payment must be made to the municipality before the start of works, without exception.
- Formalize employment, training and business development commitments in the affected territories. Document these commitments clearly and bindingly before the start of works.
- Adapt the processing schedule to the new urgent regime: coordinate with your legal and technical advisors to take advantage of the acceleration of deadlines in authorizations and environmental assessment.
- Process urban planning fit under the public works of general interest regime, which facilitates the resolution of possible conflicts with municipal planning.
- Do not reduce environmental guarantees: remember that the regulation accelerates deadlines but does not reduce substantive requirements. Maintain all environmental studies and documentation complete to avoid delays due to file deficiencies.
Frequently asked questions
How much must be paid to the municipality and when?
The promoter must pay to the municipality 3% of the project's execution budget before the start of works. There is no deferred deadline: it is a prerequisite for the start of construction. For a project with a budget of €40M, the amount is €1,200,000.
What projects are included in this strategic declaration?
Only renewable generation and energy storage projects that are awarded in the procedures for granting evacuation access capacity regulated in the twenty-second additional provision of Law 24/2013, on the Electricity Sector, and that are located in just transition hubs linked to the closure of thermal or nuclear power plants.
Does urgent processing reduce environmental requirements?
No. The regulation is explicit: environmental guarantees and substantive requirements are not reduced. Only administrative deadlines in authorizations, environmental assessment and remedies are expedited. Promoters must maintain all substantive requirements intact.
What social commitments must promoters assume?
Promoters must assume formal commitments in three areas: employment, training and business development in the territories affected by just transition. These commitments must be formalized before the start of works and form part of the conditions of the strategic declaration.
When does this regulation enter into force?
The Resolution was published in the BOE on September 7, 2026 and entered into force on that same day, with no transitional period. Affected projects are subject to this regime from that date.
