Spain Agrovoltaic Scale-Up Fund: IDAE Second Call (2026)

Spain Agrovoltaic Scale-Up Fund: IDAE Second Call (2026)

Status at the official source

This is a historical reference, not an open application listing. The Instituto para la Diversificación y Ahorro de la Energía (IDAE) closed the second call for its ENERGÍAS RENOVABLES INNOVADORAS programme on 19 February 2026 at 12:00 peninsular time. The IDAE page states that applications submitted after that deadline would not be admitted. It now reports the definitive award resolution published on 28 July 2026, so a reader should not treat this page as an invitation to submit a new application.

The official page updated on 28 July 2026 does not announce a subsequent call. That is an observation about the current IDAE page, not a promise that no future programme will ever exist. Anyone looking for a new funding window should check IDAE’s own call listings and the applicable BOE publication rather than reuse this closed call’s deadline or documents.

At a glance (official record)

What the call funded

The opportunity was a national Spanish aid line under the Recovery, Transformation and Resilience Plan, financed by NextGenerationEU. It was not a general subsidy for ordinary solar-farm construction. The relevant route was Programme 1, for innovative agrivoltaic installations with storage. IDAE describes agrivoltaics as simultaneous use of the same land for agricultural and photovoltaic production. The concept therefore required a credible relationship between the farm operation, the photovoltaic installation, and the storage system.

Programme 1 was divided into three technical subprogrammes: 1.1 for agrivoltaics intercalated with the crop, 1.2 for structures over the crop between 2 and 4 metres high, and 1.3 for structures over the crop higher than 4 metres. The exact route mattered. A conventional photovoltaic project with an informal intention to add crops later would not, by itself, demonstrate the dual-use model described by IDAE.

The wider call also covered floating photovoltaic installations in artificial spaces, renewable integration with storage in infrastructure, collective self-consumption with vulnerable consumers, and renewable heat pumps. Those routes are not interchangeable with Programme 1. This page focuses only on the agrivoltaic route and should not be used to infer the eligibility or budget of the other programmes.

Budget and aid mechanics

IDAE’s page now records three budget figures that must not be confused. The initial budget for the entire five-programme call was €202.5M. IDAE then published a first €166M expansion on 4 June 2026 and a second €65M expansion on 17 July 2026. The resulting total call budget was €433.5M. In the first distribution round described on the page, Programme 1 was assigned €212,085,787, while the other programme allocations were listed separately. The old €75M Programme 1 figure on this page described the initial cycle information and is no longer the correct current record.

The aid was awarded through competitive proceedings as a grant to be received definitively once execution was verified. IDAE states that an applicant could request an advance of 100% of an awarded aid to help finance the project, subject to the programme’s conditions. The formula used a requested generation module multiplied by installed generation power, plus the maximum storage module multiplied by installed nominal storage capacity. The aid could not exceed the eligible cost of the supported action. Module ceilings were set by technology and programme in the regulatory bases.

The call capped aid at €30M per project and beneficiary. IDAE also stated that applications were competitive, so submitting a complete file did not guarantee funding. The page records a €20,000/MW participation guarantee for applicants, with exceptions under the applicable rules, and separate conditions for a guarantee connected to an advance payment. Those details belong to the closed call and must be checked against the bases before being reused for a future programme.

Who was eligible

IDAE listed public or private legal entities as potential beneficiaries when they were legally constituted, validly established, and registered in the appropriate register, and when they met the requirements in the bases, the call, and any concession resolution. Groups of those legal entities could also be beneficiaries without a separate legal personality of their own; the entities in the group retained beneficiary status. This is narrower and more precise than saying that any farmer, informal team, or project promoter could apply.

For Programme 1, a credible applicant would therefore have needed a legally valid applicant structure and a project that fit the agrivoltaic-with-storage route. The official page says the call applied to projects in Spain and that Programme 1 could cover installations that were isolated or used for self-consumption or sale to the grid, subject to current regulation. Agricultural and energy partners could contribute to a group, but the group needed clear responsibility for the application, the legal conditions, and the project evidence.

Applicants also had to respect the incentive effect: IDAE states that only actions started after the aid application would be admitted. DNSH, or the principle of doing no significant harm to the environment, was part of the requirements. That means land rights, agricultural continuity, technical design, storage assumptions, and environmental declarations were not optional narrative decoration; they were part of the evidence needed to support a compliant project.

What a strong historical application would have contained

Although the window is closed, the application record is useful for understanding the standard expected by this type of call. A serious file would have connected five parts:

1. Agricultural operation. The project should explain the crop, access routes, machinery, irrigation, seasonal work, shading assumptions, and how farming remains a real use of the land.

2. Photovoltaic and storage design. The chosen subprogramme, structure height, generation capacity, storage capacity, and operating model should agree with one another and with the requested aid modules.

3. Legal and site control. The applicant or group would need to establish the relevant legal identity, representative authority, land or access rights, and any other conditions required by the bases and call.

4. Execution and finance. The budget, procurement sequence, permits, construction plan, commissioning plan, and source of non-grant finance should be realistic. Awarded installations had to be fully completed by 30 June 2030, and the justification period was 3 months after that maximum execution period.

5. Environmental and administrative compliance. The applicant would need the declarations and supporting material required by the selected route, including the DNSH commitment, and would need to keep the project consistent with the PRTR requirements.

The official page says the evaluation used the criteria in the regulatory bases and a technical valuation process, producing a score from 0 to 100. A polished concept was not enough. The proposal needed to make the agricultural, energy, financial, legal, and environmental claims mutually consistent.

How applications were submitted

The submission route was fully electronic through IDAE’s tramitador. The official instructions say the application could only be made with the representative’s electronic signature. The platform returned a receipt with the registration date and time and an assigned file number; IDAE treated the application as definitively submitted and registered at that point.

The practical sequence for the closed cycle was:

1. Confirm the legal entity or group and its representative.
2. Select Programme 1.1, 1.2, or 1.3 and document the agrivoltaic design and storage configuration.
3. Prepare the technical memory, budget, module calculations, site evidence, declarations, and other documents required by the form and the applicable bases.
4. Create the electronic file in the IDAE application, complete the beneficiary, representative, contact, project, evaluation, legal, and declaration sections, and upload the required documents.
5. Use the platform’s save-and-validate flow to correct missing fields or documents.
6. Sign and register the final application electronically, then retain the receipt, date and time, file number, and submitted package.

Those steps describe how the 2026 call worked; they are not instructions to submit now. The 19 February 2026 deadline has passed, and the official page says applications after that point would not be admitted.

Result and project horizon

IDAE’s definitive-resolution notice reports 524 awarded files, €433,440,381.54 in total aid, €1,186,191,236.38 in total investment, 1,225.66 MW of total power, and 2,320.72 MWh of storage. The page says awarded installations must be fully completed before 30 June 2030 and that beneficiaries must provide a semi-annual implementation report. It also reiterates the DNSH and climate-tagging obligations attached to the recovery-plan funding.

These result figures explain why the page remains useful as an archive entry even though it is no longer actionable. They show the scale of the selected portfolio and provide a fixed reference for researchers, developers, and public bodies comparing agrivoltaic support programmes. They do not mean that funds remain available under this call, and they do not establish that a new cycle has opened.

Research and monitoring notes

The official source to monitor is the IDAE electronic-sede page linked in the metadata. Its attachments include the user manual, technical-memory template, frequently asked questions, beneficiary declarations, PRTR declarations, the DNSH declaration, the provisional and definitive resolutions, and the budget-expansion resolutions. A future call may change the forms, programme boundaries, budget, guarantees, deadlines, or application route, so the documents from this closed cycle should not be copied without checking their publication status.

For an organisation preparing for a later opportunity, the most useful next step is to build a reusable evidence file rather than claim that this call is still open. Keep the legal-registration material current, document land control and agricultural operations, maintain a storage and generation model that can be audited, and track the IDAE and BOE notices for a new resolution. The next official publication, if one appears, should control the new deadline and amount.

Frequently asked questions

Can I apply now?

No. The official page states that the application window ended on 19 February 2026 at 12:00 peninsular time and that later applications would not be admitted.

Is the €75M Programme 1 figure still current?

No. IDAE now reports a total call budget of €433.5M after the two 2026 expansions and lists €212,085,787 for Programme 1 in the first distribution round. Use the official page and resolution for the final award record.

Is this a normal solar-farm grant?

No. The relevant route supported innovative agrivoltaic installations with storage, combining agricultural and photovoltaic use of the same space. Ordinary photovoltaic generation without the required project fit should not be assumed eligible.

What should a future applicant do?

Check IDAE’s current programme page and the BOE notice for a newly announced call. Then confirm the new deadline, budget, beneficiary rules, technical subprogrammes, forms, guarantees, environmental conditions, and electronic submission route from those documents.
