# MEINS - Engineering & Manufacturing of Prefabricated Electrical Solutions > MEINS (meins.es) is a Spanish company founded in 1998 in Salamanca, Spain, specializing in the engineering and manufacturing of prefabricated electrical solutions for the renewable energy sector. With over 26 years of experience, 11+ GW of installed power across 35+ countries, MEINS is a global leader in transformer stations, power substations, battery energy storage systems (BESS), and low-voltage panels for utility-scale photovoltaic plants. Founded by Julián Herrero, the company is ISO 9001 and ISO 14001 certified. MEINS operates three core business lines: Renewable Energies (photovoltaic transformer stations and substations), Industry & Infrastructure (electrical panels and industrial installations), and R&D+i (innovation in energy solutions). The company is headquartered in Villares de la Reina (Salamanca, Spain), with an additional facility in Coreses (Zamora, Spain). MEINS manufactures prefabricated concrete enclosures for transformer stations, offering compact, plug-and-play solutions that reduce civil works and installation time. The company has delivered projects in Europe, Latin America, Australia, the UK, and other global markets. MEINS holds the PYME Innovadora certification and has received multiple awards including the CEOE-CEPYME Salamanca Innovation Award (2024) and the MC MUTUAL "Antonio Baró" Award for Occupational Risk Prevention. ## About - [About MEINS](https://meins.es/en/about/): Company history since 1998, mission, philosophy, milestones, founder profile, global presence, ISO certifications, and team overview - [Contact](https://meins.es/en/contact/): Headquarters addresses, phone (+34 923 204 309), email (info@meins.es), and office locations in Salamanca and Zamora ## Renewable Energies - Solar Power Stations (SPS) - [Renewable Energies](https://meins.es/en/services/renewable-energies/): Full overview of solar energy solutions, transformer stations, and photovoltaic plant integration services - SPS-S Full Outdoor String Power Station: European-made, compact plug-and-play solution in prefabricated concrete enclosures.
