Mérida is for us in Extremadura a specific strategic market — smallest by population (60,000 inhabitants), but with the strongest solar and renewable energy cluster in all of Spain. Iberdrola Renovables Extremadura operates the largest solar cluster in ES — solar fields with total installed capacity over 1 GW. Plus ENRESA Almonacid de Zorita for nuclear decommissioning. From Prešov it's a 4.5-hour flight via VIE or FRA to BJZ Badajoz (60 km by car) or MAD (340 km by car). We have no overland commute.
Iberdrola Renovables Extremadura — Spain's largest solar cluster
Extremadura is the main solar autonomy in Spain — extremely high insolation (averaging 5.5 kWh/m²/day), low land price and regional incentive programs have created a cluster of solar projects that in 2020-2026 grew to over 1 GW of installed capacity. Iberdrola Renovables is the dominant operator with a decision point in Bilbao and physical realisation in Extremadura.
For an integrator with expertise in **photovoltaic inverter integration, SiC power semi and battery energy storage system (BESS) deployment**, Extremadura is a key segment in Spain. Concrete types of work:
- **Inverter integration** — string inverter (SMA Sunny Tripower, Huawei SUN2000) or central inverter (Power Electronics, Ingeteam, Sungrow) for larger fields, - **SCADA for solar fields** — typically Ingeteam INGECON SUN Manager or SMA Cluster Controller, integration into the national grid code via REE procedimientos de operación, - **BESS** — battery storage for frequency response and peak shaving, notably BYD, CATL or Tesla Megapack, - **DC arc fault detection** — UL 1699B compliance for Class III fire risk.
For us the Extremadura solar cluster is a segment where we have direct transferable competencies. Without a delivered solar project we don't yet have a local name, but the technology stack for SCADA, inverter integration and BESS deployment is ready.
ENRESA Almonacid de Zorita — nuclear decommissioning
ENRESA (Empresa Nacional de Residuos Radiactivos) operates in Almonacid de Zorita (Castilla-La Mancha, but within reach of Extremadura) decommissioning of the first ES nuclear power plant José Cabrera (closed 2006). For an integrator decommissioning of a nuclear facility is a segment with extremely strict regulatory geography (CSN nuclear safety framework, IAEA safeguards, special radiation protection protocols).
For us ENRESA is a segment where for nuclear safety related zones we aren't directly deliverable. For administrative, IT and maintenance zones outside NSR classification we're realistically deliverable via subcontractor model.
Catalana Occidente, BAS-2 Extremadura
Catalana Occidente Mérida (insurance) is a smaller financial player with a strong administrative presence. For an integrator relevant via IT infrastructure — fibre backbone, structured cabling in office space.
BAS-2 Extremadura (Badajoz, adjacent area) is a biotech operation for agricultural applications. For us a pure process segment via Industry + Automation.
Cementos Cosmos Niebla
Cementos Cosmos Niebla (Huelva, adjacent Andalusia) is a cement industry within reach of Extremadura logistics. For an integrator relevant via process production and ATEX dust zones.
Regulatory framework — Extremadura
Extremadura operates under the national REBT (RD 842/2002), UNE-HD 60364, UNE-EN 60204-1 and ATEX transposition via RD 144/2016. **Junta de Extremadura** adds a regional authorisation layer via Consejería para la Transición Ecológica y Sostenibilidad.
For the solar segment **REE (Red Eléctrica de España)** is key with national procedimientos de operación for connection of generating units to the national grid. For large solar fields (over 50 MW) ENTSO-E grid code compliance is added.
For ENRESA nuclear decommissioning **CSN (Consejo de Seguridad Nuclear)** with its own strict vendor framework. For building permits CTE plus Extremadura implementing decree.
Posted Workers — REC for Extremadura
REC registration 5 days in advance remains national. For Extremadura a regional copy isn't required. For Iberdrola Renovables an internal supplier framework with strict Health & Safety audit is added. SMI €1,184/month plus Convenio Colectivo Estatal de Industria.
Our commuting relationship
For Mérida we work exclusively by air. The most practical access is via MAD Madrid Barajas (340 km by car, 3h 30min) or BJZ Badajoz (60 km by car, 1 hour). BJZ has limited connections from BCN and some seasonal international destinations.
Accommodation typically in Mérida centre. For solar fields in the surrounding Extremadura (Cáceres, Plasencia, Don Benito, Almendralejo) transport by car 50-100 km from Mérida.
Rolling-team regime for repeat cooperation, **three-week minimum scope of work** due to smaller market and two-step logistics (flight + car from Madrid).
Which pillars fit best
For **Iberdrola Renovables Extremadura solar cluster — the strongest segment in ES for us**. Electro + Automation with focus on PV inverter integration, SCADA for solar fields, BESS deployment, SiC power semi. Here we're in a pre-engagement phase with directly transferable competencies.
For ENRESA nuclear decommissioning — for nuclear safety related zones not deliverable, for administrative/IT and maintenance zones outside NSR deliverable.
For Catalana Occidente and BAS-2 — **Software/AI + Data Centres** in the plane of IT infrastructure and process production.
Conclusion
**Extremadura is for us in Spain, together with Pamplona, a priority renewable energy target.** The Iberdrola Renovables solar cluster is a segment where we have directly transferable competencies from SCADA and inverter integration work. For the first Extremadura client we're ready with a rolling-team regime with three-week rotation.
