Meins, a company specialising in prefabricated medium- and high-voltage electrical solutions, is consolidating its position in strategic areas of the energy sector, including renewable energy, hydrogen and data centres, while advancing an ambitious international expansion plan.
With consolidated operations in countries such as Spain, Germany, the United Kingdom and Ireland, the company has already surpassed 11 GW of installed capacity associated with solutions delivered. Meins is currently involved in projects linked to solar photovoltaic plants, energy storage systems and the reinforcement of electricity distribution infrastructure, while progressing with regulatory and technical preparations to enter the US market.
At the same time, the firm is strengthening its footprint in key European markets, while assessing future positioning in Latin America and North and Central Africa, regions it sees as offering medium-term growth opportunities.
“We are ready to make a step change in scale, technology and markets by optimising construction techniques based on modular and prefabricated solutions,” said Alejandro González García in an interview with Energía Estratégica. “Building on our international know-how in supplying transformer substations, we aim to replicate the same growth trajectory with the supply and installation of our compact substation solutions.”
From his perspective, the coming years will be defined by the industry’s ability to deliver efficient, scalable and reliable solutions in increasingly demanding environments, against the backdrop of a growing shortage of qualified technical personnel, particularly in high-voltage engineering.
The Spanish company designs and manufactures medium- and high-voltage transformer centres and substations, serving applications ranging from renewable generation assets to industrial facilities and critical infrastructure. Meins is currently active in 35 countries and has delivered solutions linked to more than 11 GW of power capacity worldwide.
Recent financial performance underpins this expansion. Meins expects to close 2025 with revenues exceeding €60 million, representing 20% year-on-year growth. During the same period, the company delivered more than 300 transformer centres and substations, adding over 1.5 GW of associated capacity, and advanced the commercialisation of two new developments in hydrogen, energy efficiency and biotechnology, driven by its R&D activities.
Looking ahead to 2026, the company has set ambitious targets: more than €70 million in revenues, the delivery of over 450 solutions, and accelerated growth in industrial sectors requiring critical, secure and fast-to-deploy power infrastructure.
One of these priority segments is data centres, where Meins is preparing a dedicated portfolio of electrical solutions for deployment across Europe, with plans to later replicate the model in Latin America and Africa.
“The growth in global demand for data centres is enormous,” González García said. “These are large-scale projects that prioritise efficiency, reliability and speed of execution, and that is precisely where our solutions deliver strong added value.”
In the hydrogen segment, Meins is taking a more strategic, medium-term approach. Beyond supplying the associated electrical infrastructure, the company is also developing its own hydrogen generation system, based on technologies that go beyond conventional electrolysis. Although investment momentum in hydrogen has slowed, Meins expects a second growth wave focused on more concrete and scalable applications.
Innovation, industrial expansion and a strategic view of the energy market
The core of Meins’ business model lies in the design and manufacture of modular, prefabricated transformer centres and high-voltage step-up substations, an approach that shortens project timelines, reduces execution risks and improves overall solution quality. This positioning allows the company to serve both renewable power plants and complex industrial installations and critical infrastructure.
After consolidating the CSET solution in the Spanish market during 2025, Meins is now focused on scaling the technology internationally, preparing both operationally and in regulatory and commercial terms to support deployment in multiple regions.
One of its most disruptive innovations is the CSET compact substation, designed to address the growing shortage of specialised high-voltage technical resources. The solution can reach up to 100 MVA per transformer at 138 kV, with on-site implementation completed in less than 10 days, including civil works, electromechanical installation and functional testing. By comparison, a conventional substation typically requires six to ten months, while the physical footprint of the CSET solution can be up to ten times smaller.
Another strategic milestone is the planned relocation of the company’s headquarters to new facilities covering 85,000 m² in Salamanca by 2030. Together with its existing industrial plant in Coreses (Zamora), this will allow Meins to exceed 100,000 m² of total industrial space. The new site will integrate corporate offices, the R&D centre, a low-voltage switchgear factory, and dedicated areas for the integration and storage of medium- and high-voltage solutions.
Meins’ market analysis also reflects current dynamics in Spain, where a slowdown in solar PV investment, linked to falling power purchase agreement (PPA) prices, has increased interest in battery energy storage systems and hybrid solutions as alternatives to improve project economics.
In this context, González García warns that regulatory uncertainty continues to hinder the deployment of energy storage in markets such as Spain, and calls for greater regulatory clarity to unlock sustained investment.
In terms of its client base, Meins has shifted towards medium- and long-term partnerships, supported by framework agreements with international engineering, procurement and construction (EPC) contractors and developers. More than 50% of its current portfolio corresponds to German companies, 31% to Spanish firms, with the remainder distributed across other markets.
This strategy reflects a deliberate focus on partners that value design flexibility, product quality and risk reduction.
Finally, Meins’ solutions stand out for their high European content, in some cases exceeding 95%, reinforcing local supply chains and reducing external dependency. Its prefabricated concrete buildings provide an additional competitive advantage over metal-based alternatives, offering greater durability, improved fire resistance, superior thermal and acoustic insulation, and lower lifecycle maintenance costs over the asset’s operational life.
