Galicia, Basque Country, Navarra & Aragón Tender Portals

Introduction

Spain's regional procurement systems offer access to government contracts issued by autonomous communities, municipalities, public agencies, healthcare organisations, universities and other public sector entities. For suppliers seeking opportunities beyond the national procurement platform, understanding the regional portals can improve tender discovery and help identify buyers with recurring requirements.

Four regions with distinct procurement environments are Galicia, the Basque Country, Navarra and Aragón. Each provides official procurement information, but the portal structure, terminology, electronic submission arrangements and regional administrative requirements differ.

This guide explains where to find public tenders in these four regions, how to search by contracting authority and CPV code, how to locate tender documents and contract awards and what suppliers should check before submitting an offer.

Why Regional Tender Portals Matter

Spain's public procurement market is not limited to one website. The national Plataforma de Contratación del Sector Público (PLACSP) is an important discovery source, while autonomous communities operate regional procurement services or use arrangements that connect with the national platform.

Regional portals can help suppliers discover opportunities published by local and regional authorities, access the official documents and monitor changes to a procurement procedure. They are particularly useful when a business targets a specific geography or wants to identify repeat buyers in a defined sector.

For regional research, suppliers should combine location-specific searches with contracting authority names, CPV codes, contract types and current submission status. Search in the relevant regional language as well as Spanish where appropriate.

Galicia Public Tender Portal

The official regional platform is Contratos Públicos de Galicia, available through the Xunta de Galicia's procurement services. It provides procurement notices and search tools for businesses looking for licitaciones Galicia, Xunta contracts and other public sector opportunities in the region.

The portal offers access to prior notices, preliminary market consultations, tender announcements and other procurement information. Its search interface includes filters for contracting authority, CPV subject area, procedure type, contract type, procurement system and the status of the procedure.

Suppliers can also find links to the Sistema de Licitación Electrónica (SILEX), the Registro General de Contratistas de Galicia and other procurement resources. The precise process for participating in a tender depends on the authority and the instructions published with the individual contract.

How to Search Galicia Tenders

Start with the official Contratos Públicos de Galicia search page. Use a precise product or service keyword, then refine the results with the available filters.

• Keyword: search for the service, product, project or works category.
• Contracting authority: identify Xunta departments, public bodies or other buyers.
• CPV classification: narrow results by the relevant Common Procurement Vocabulary category.
• Procedure: review the available procurement procedure filters.
• Status: focus on notices that are still within the offer submission period.

Galician and Spanish terms may both be useful. For example, a supplier may try both “servizos informáticos” and “servicios informáticos” when searching for IT services.

Open each relevant expediente to inspect the contract description, estimated value, submission deadline, award criteria and tender documents. Do not rely only on the short search result.

SILEX and Electronic Tendering in Galicia

SILEX is the electronic tendering system associated with Galicia's procurement services. When a tender requires electronic submission, suppliers should follow the link and technical instructions provided in the official procurement record.

Before preparing the final bid, confirm the accepted electronic identification and signature method, account requirements, file formats and document-upload process. Requirements may differ between procurement procedures and systems.

Galicia also provides access to its General Register of Contractors. Suppliers who regularly participate in regional procurement can review the register's purpose, eligibility conditions and current registration process. Registration should not be assumed to replace every document required by an individual tender.

Always submit early enough to resolve technical issues and retain the system's evidence of successful submission.

Basque Country Public Tender Portal

The Basque Country's official procurement environment is Contratación Pública en Euskadi, also known through its Basque-language name, Kontratazio Publikoa Euskadin. The associated platform is commonly referred to as KPE-CPE or KontratazioA.

The portal provides contracting profiles, tender announcement searches, electronic bidding services and information about the public procurement activities of authorities in the Basque Autonomous Community. The platform covers a broad network of contracting authorities, including regional, provincial and local public bodies.

The official site also provides access to the Registro de Empresas Licitadoras y Clasificadas de la Comunidad Autónoma de Euskadi and public contract register information known as REVASCON.

Because the Basque Country has its own regional procurement infrastructure, suppliers should check the Euskadi platform even when they already search the national PLACSP.

How to Search Euskadi Tenders

Use the portal's “Búsqueda de anuncios” option to locate procurement notices. Search by contracting authority, contract description or other available criteria, and filter by the status “Abierto / Plazo de presentación de ofertas” when seeking opportunities that are currently accepting bids.

When you open a notice, review its contract details, contracting organisation, CPV code, place of execution, award criteria, submission location and language information. The official help pages explain how to search announcements and navigate the notice details.

Basque and Spanish search terms can expand coverage. For example, suppliers may search using both “obras” and “obrak” for works-related opportunities, then verify the contract description and scope.

The Basque procurement portal and PLACSP have an interoperability arrangement through which procurement notices may be presented on both platforms. Even so, suppliers should follow the official notice and submission instructions for the specific procedure.

KontratazioA and Electronic Bidding

The Basque procurement platform provides electronic tendering services for eligible procedures. The individual tender's administrative specifications determine whether electronic submission is mandatory and explain the process to follow.

The regional site recommends that companies consider registration in the Basque Country's Register of Tenderers and Classified Companies, the national ROLECE register or the platform's internal register, as applicable. Registration can reduce repeated document requests, but the precise requirement depends on the procedure.

Check digital certificate compatibility, representative authority, account access and technical requirements before starting the final submission. The official platform provides instructions, training resources and support information for companies.

If bidding as a temporary union of businesses (UTE), check the platform's specific procedure for joint participation and any temporary authorisation requirements.

Navarra Public Tender Portal

The official Portal de Contratación de Navarra is the principal public procurement publication and transparency portal for the Chartered Community of Navarra. It provides procurement information for entities subject to Navarra's regional public contracts law.

The portal includes sections for tender announcements, prior information notices, awards, cancelled or unsuccessful procedures, contract extensions, preliminary market consultations and other procurement information.

Unlike the procurement environments in the other three regions, Navarra operates under its own regional public contracts legislation, including Ley Foral 2/2018, de Contratos Públicos. Suppliers should therefore pay particular attention to the applicable legal framework and the instructions in each tender.

The portal also provides information about PLENA electronic tendering, supplier registration, the voluntary register of tenderers and the bodies responsible for procurement oversight and complaints.

How to Search Navarra Tenders

Use the portal's tender announcement search and choose the relevant procurement category. Suppliers can review current notices for works, supplies, services and concessions and access information about other public contracting activities.

For a practical search:

• Search by the contract's description or relevant product and service terms.
• Identify the contracting authority and its procurement profile.
• Review current tender announcements and the submission period.
• Examine award notices to research previous procurement outcomes.
• Check preliminary notices and consultations for potential future demand.
• Use available subscriptions or alert features where useful.

Navarra's portal provides information across different stages of procurement. A notice that is no longer open may still be valuable for competitor research or identifying the authority's recurring requirements.

PLENA Electronic Tendering in Navarra

PLENA is the electronic tendering environment referenced by Navarra's procurement portal. The portal provides routes for tenderers to register, access their private area and submit electronic offers.

Suppliers should confirm which version or workflow is relevant to the particular procedure, because the official portal provides access to PLENA 2.0 and legacy PLENA resources. Follow the instructions in the procurement file rather than choosing a system independently.

Check the requirements for electronic identification, signatures, documentation and final submission. Ensure that the person submitting the offer has the necessary authority and that the required files are complete.

Navarra's regional framework can differ from the general state procurement regime in important respects. When assessing a tender, read the applicable *pliegos* and relevant regional legal provisions instead of assuming that every rule is identical across Spain.

Aragón Public Tender Portal

The Government of Aragón's Plataforma de Contratación del Sector Público de la Comunidad Autónoma de Aragón is the regional reference point for procurement information and services.

The regional procurement area provides information about contracting profiles, standard administrative specifications, contractor and contract registers, centralised procurement and the regional legal framework.

Aragón's procurement framework includes national legislation and the regional Ley 11/2023, de 30 de marzo, de Uso Estratégico de la Contratación Pública de la Comunidad Autónoma de Aragón. Suppliers should check which provisions and procurement instructions apply to the authority issuing a particular contract.

An important operational point is that Aragón's official guidance states that, since 9 March 2018, contracting profiles for the regional public sector and participating local authorities have been hosted on the national PLACSP. As a result, suppliers should use the Aragón regional information pages to understand the system and then follow the relevant contracting profile and official publication.

How to Search Aragón Tenders

Start with the Government of Aragón's procurement information page to identify the relevant contracting profile, register or centralised procurement resource. For individual notices, follow the link to the appropriate profile hosted on PLACSP where applicable.

Search by contract description, contracting authority, CPV code, procedure and publication status. Review the official tender record for the contract value, submission deadline, award criteria and required documents.

Suppliers interested in repeat purchases should also examine Aragón's centralised procurement information. Centralised arrangements can cover goods and services that public entities require regularly, although participation rules depend on the specific framework or procurement mechanism.

Aragón Contractor Register

Aragón operates a regional Register of Tenderers, known as the Registro de Licitadores de Aragón. According to the regional government's guidance, registration can simplify administrative procedures by allowing certain company information and supporting documentation to be verified through the register.

The register can include details such as the company's legal name, business purpose, registered address, contractor classification, representative powers, grounds affecting eligibility and annual accounts for the specified periods.

Registration is generally voluntary, but Aragón's official guidance identifies simplified open procedures, including the abbreviated form, as procedures where registration in the regional register or ROLECE is required by the applicable rules at the relevant deadline.

Companies should verify the current requirements for the tender they intend to enter. The register's existence does not mean that every procurement in Aragón uses identical registration rules.

Compare the Four Regional Tender Portals

The most important difference is not simply the portal's design. It is the way each region organises its contracting information, electronic bidding services and regional legal framework. Navarra has a distinct regional public contracts law, while Aragón's official guidance directs suppliers to PLACSP-hosted profiles for many contracting authorities.

How to Find Tenders Across All Four Regions

Suppliers that serve multiple Spanish regions should adopt a consistent discovery process rather than treating every portal as an unrelated source.

• Define your target categories: list the products, services and works your company can deliver.
• Map relevant CPV codes: include primary and related codes to reduce missed opportunities.
• Search regional portals: use the official search tools in Galicia, Euskadi, Navarra and Aragón.
• Search PLACSP: include national-platform notices and contracting profiles, particularly for Aragón.
• Use local terminology: try Spanish and the relevant regional language where applicable.
• Monitor deadlines: record the final submission date and check amendments before bidding.
• Review awards: use historical procurement outcomes to understand buyers and competitors.

Maintain one opportunity register with the authority, region, expediente number, CPV code, estimated value, deadline, procurement platform and bid decision. This makes it easier to compare opportunities and allocate bid preparation resources.

Documents and Eligibility Requirements

Although the exact rules vary by procedure, suppliers commonly need to review the administrative specifications (*PCAP*), technical specifications (*PPT*), declarations, solvency evidence and electronic submission instructions.

Depending on the contract, requirements may include proof of legal capacity, representative authority, financial solvency, technical experience, professional licences, insurance or certificates. Electronic signatures and platform registration may also be required.

Foreign suppliers should confirm document translation and authentication requirements. Businesses operating across regions should not assume that a registration or technical workflow used for one procurement authority automatically satisfies the requirements of another.

Common Regional Tender Search Mistakes

• Searching only PLACSP: regional portals can provide useful search tools and context even where publication is interoperable.
• Ignoring regional language terms: relevant opportunities may use Galician or Basque wording.
• Assuming all regions use the same law: Navarra has its own regional public contracts law, and Aragón has additional regional procurement legislation.
• Confusing a notice with a live opportunity: always check the current submission status.
• Overlooking electronic bidding requirements: SILEX, Euskadi's bidding services and PLENA have their own instructions.
• Ignoring amendments: revised documents or deadlines can change a bid's requirements.
• Skipping award research: past awards can reveal recurring buyers and competitive patterns.
