What’s the news about new products/services?
J.S.B: Meins launched in the summer of 2024 what it considers one of its most significant and market shaping products to date, the CSET prefabricated compact substation. This solution fully reflects the company’s philosophy of disruptive, tailor-made turnkey solutions, expected to play a transformative role not only in the energy sector but also across industrial applications.
The CSET concept was developed in response to a clear market need to drastically reduce project execution timelines, on-site construction periods, and the overall physical footprint of substations. Unlike conventional outdoor substations, the CSET is conceived as a compact, plug-and-play solution, delivered as modular units that are assembled on site in a “puzzle-like” configuration, significantly simplifying installation and commissioning.
From a technical perspective, this solution can reach up to 100 MVA per transformer and operate at insulation voltages up to 145 kV, incorporating GIS technology, and enabling complete on-site implementation in less than ten days, including civil works, electromechanical installation, and functional testing compared to the usual six to ten months required for a conventional substation. Additionally, its design reduces the physical footprint by up to ten times compared to traditional solutions which is a major advantage in industrial areas where space is at a premium, both from an economic perspective and for efficient utilization of available land. Even, the financial model is more attractive compared to conventional substation concepts, offering greater flexibility and reduced upfront costs.
In fact, given the disruptive of this solution and its broad market potential, Meins has developed a full-scale showroom installation at its own facilities, allowing customers to experience first-hand the concept, functionality, and advantages of the CSET solution.
At the same time, the company is developing a dedicated line of modular electrical solutions for data centers, and hydrogen applications, designed to meet the reliability, energy efficiency, and rapid installation requirements of these critical infrastructures.
In the field of hydrogen, Meins has developed an innovative system for producing renewable hydrogen through bioethanol reforming. This is a transportable, scalable, and on-demand production solution, designed to facilitate the progressive deployment of hydrogen in mobility applications without relying on large-scale electrolysis plants.
Furthermore, the R&D&I department is driving new developments in energy efficiency and the circular economy, including thermal storage systems and advanced freeze-drying solutions that allow biological samples to be stored without the need for ultra-freezing.

What is the state of the market where you are currently active?
J.S.B: The insights we have, together with those shared by our customers and suppliers, indicate that the European energy market is undergoing a period of significant transformation and change. We are observing a substantial increase in electricity demand, accompanied by the need for reliable infrastructure that can be deployed rapidly. This environment drives the search for innovative solutions that enable more remote, efficient, and flexible system management, adapting to the current demands of the sector.
In the photovoltaic sector, we have recently seen a slowdown in new investments in certain markets, driven by falling PPA prices. This situation has encouraged the development of hybrid projects with energy storage as an alternative to improve profitability and ensure the stability and quality of electricity supply. Such solutions are growing significantly across much of Europe, with the goal of integrating renewable energy without compromising grid reliability. In Spain, in particular, this trend has accelerated following the blackout that occurred in April 2025.
Within this context, the company maintains a strong position in hybrid systems while also exploring opportunities in markets beyond Europe. Examples include projects in Latin America, such as those developed in Guatemala and El Salvador, as well as in European countries like Italy and Romania, where the promotion of renewable energy creates new growth opportunities.
At the same time, sectors such as data centers, energy storage, and high electricity-consuming industries are experiencing strong growth, generating new opportunities for modular and prefabricated electrical solutions. In this space, we position ourselves as a key player, capable of providing solutions that meet the needs of these expanding markets.
In conclusion, MEINS continues to hold a solid position, ready to seize emerging opportunities in a constantly transforming environment, thanks to its international presence, up-to-date market knowledge, and stable collaboration with EPC contractors and energy project developers.
What can you tell us about market trends?
J.S.B: We observe several clear trends in the energy sector. On one hand, as mentioned earlier, the integration of energy storage systems, hybrid solutions, and technologies that enhance grid stability is becoming increasingly important, driven in part by the growth of data centers and other critical infrastructure, which is creating a rising demand for safe, efficient, and rapidly deployable electrical systems. On the other hand, digitalization, asset optimization, and more flexible business models are gaining momentum, particularly in mature markets such as Europe, where we currently focus our activity, while also expanding into other regions.
Aligned with these trends, we are taking initial steps in the development of digital substations, with remote and intelligent solutions that allow to manage issues without the need for on-site intervention.
We also detect a growing trend toward concentrating higher power and voltage levels in increasingly compact spaces, driving the development of more compact solutions, an area in which we are experts. Currently, we are expanding the capabilities of our medium voltage solutions, reaching up to 10 MVA and 40.5 kV of insulation, adapted to numerous sectors and applications. At the same time, we are exploring the possibility of increasing the capabilities of other products, such as the CSET, which currently reaches 100 MVA and 145 kV of insulation, and the FSET, with 10 MVA and 66 kV of insulation.
Following this tendency, the energy sector is also moving toward increasingly modular, industrialized, and fast-to-deploy solutions, driven both by the shortage of qualified technical personnel and the need to reduce construction times and accelerate project implementation. This is accompanied by greater electrification of the industrial and transport sectors, as well as systematic integration of storage into renewable energy systems.
At the same time, hydrogen is emerging as a strategic long-term energy vector. Although it is still in the early stages of technological development and infrastructure deployment, we are optimistic that its adoption will become significant in the medium to long term.
