The most distant and most developed southern market
Spain is the most geographically distant market we actively track — from Prešov to Madrid is realistically a 4-hour flight via VIE or FRA, since driving (3 days with stops) isn't on the table. Even with the distance, the ES locale on our website is strategic — Spain is the EU's fifth-strongest industrial economy and we're actively working on opening the first client.
Regulatory framework
The Spanish electrical installation standard is **REBT — Reglamento Electrotécnico para Baja Tensión** (Real Decreto 842/2002) — the baseline low-voltage installation regulation, currently revised via Real Decreto 542/2020. Thanks to a unified REBT, the same applies across the whole of Spain, unlike the country-differentiated BauO in DE/AT.
For special environments **UNE-HD 60364** (the European harmonised series) adds in, **UNE-EN 60204-1** for machinery, and **ITC-BT (Instrucción Técnica Complementaria — Baja Tensión)** a set of 51 instructions detailing REBT for specific zones (medical, explosive, wet, ground-contact, etc.).
For building permits **CTE — Código Técnico de la Edificación** applies as the technical code for construction. For occupational safety **Ley 31/1995 PRL (Ley de Prevención de Riesgos Laborales)** plus **RD 614/2001** specifically for electrical risk.
For ATEX zones, the Spanish transposition of Directive 2014/34/EU via Real Decreto 144/2016.
Posted Workers — the process
A Slovak supplier in Spain needs: A1 from Slovak Social Insurance, **comunicación de desplazamiento** via REC (Registro de Empresas y Trabajadores) — electronic form, registration at least 5 days before work begins. In some autonomous communities (notably Catalonia, Euskadi) a regional copy of the registration is added.
Pay must comply with the Spanish minimum wage **SMI (Salario Mínimo Interprofesional)** — currently €1,184/month from 1 January 2025 — plus the **convenio colectivo** (collective agreement) for the sector. For electrical installation, Convenio Colectivo Estatal de Industria, Tecnología y Servicios del Sector del Metal.
Cross-border VAT under Art. 84 LIVA (Ley del Impuesto sobre el Valor Añadido) — reverse-charge mechanism, we issue invoices without VAT marked "Operación con inversión del sujeto pasivo" or "VAT reverse-charged".

Our commuting relationship
From Prešov to Madrid is 4 hours' flight via Vienna or Frankfurt. For ES projects we work exclusively by air with accommodation for 1 to 6 weeks within reach of the client. For repeat cooperation we'd set up a rolling-team regime (team rotates every two weeks, project runs continuously).
ES is realistically the most demanding market in terms of personnel logistics and cost calculation. For a competitive bid a minimum two-week scope of work is necessary; shorter contracts don't cover the travel.
Where we're opening up in Spain
Renewable energy cluster Pamplona / Seville (Iberdrola, Acciona, Gamesa Siemens) — for an integrator with SiC power semi experience and high-voltage battery installation expertise, an open segment is here. Wind-farm controller integration, solar PV inverter integration, battery storage systems.
Automotive supplier orbit Volkswagen Pamplona + SEAT Martorell + Stellantis Zaragoza — Sondermaschinenbau and robotic-cell integration in the EV transformation phase.
IT/AI cluster Málaga — Google Cybersecurity Engineering Hub and Vodafone Innovation Hub create demand for data centre capacity and DCIM services.
Madrid data centre hub — strategic target, technologically directly transferable from our Romanian reference.
Language
For ES clients we work in the Spanish locale with a formal register (usted/ustedes for B2B context). For business meetings we combine Spanish for business contact and English for technical engineering, where it's terminologically demanding to hold a fully ES dialogue. For project documentation we use professional ES translation with technical review.
