Romania is at a decisive moment in its energy transition. After the accelerated development of renewable capacity, the next stage is about integrating the energy produced into a smarter, more flexible system, connected to the needs of the economy. A major challenge is the efficient use of renewable energy, often limited by grid congestion, lack of storage, insufficient local consumption and ageing infrastructure. This is where LIMES-X comes in: transforming underused green energy into economic value and reducing pressure on the grids. The LIMES-X platform proposes a Digital Energy Campus that integrates renewable energy, BESS systems, high-performance computing infrastructure, electric mobility and energy communities. Its experience in distribution, grid connection and electrical infrastructure supports the shift from standalone energy projects to integrated platforms capable of creating economic, technological and social value. We spoke with Alin Daniel Crăciunescu, COO of CRC ENERGY and co-founder of LIMES-X, about how Romania can move from simply producing renewable energy to integrated platforms that combine storage, local consumption, digital infrastructure, electric mobility and energy communities, in order to make smarter use of the green energy that is currently lost or remains underutilized.

 

You gained experience within the Enel Group, in the distribution area. How did this professional stage influence you?

My experience within the Enel Group was essential to my professional development. Working in an energy group of that scale gives you rigor, operational discipline and a very concrete understanding of how energy infrastructure works.

In the distribution area, you quickly understand that the grid is not just a technical map or a set of regulations. It is a living system, with real limitations, processes, responsibilities and constraints. You learn what a grid connection process means, how a technical connection approval is managed, where bottlenecks appear, and how important protections, permits, proper execution and coordination between all parties involved really are.

This experience also showed me the difference between operating a system and trying to transform it. Distribution system operators have an essential role, but a strictly regulated one. They cannot act as developers of integrated platforms. Instead, the market needs players who understand the grid, but who can build new models around it.

This is exactly where the decision to move towards the entrepreneurial area came from. I saw that Romania has renewable projects, real flexibility needs, industrial consumers, municipalities interested in energy independence, farmers who can become important players in local energy production and consumption, and growing pressure for digital infrastructure powered by clean energy.

What is missing is an integrator able to bring all these elements together into a coherent model and transform unused or undervalued renewable energy into a real economic resource.

 

What is LIMES-X, explained simply?

LIMES-X is a Digital Energy Campus platform. In practice, we are talking about a hub that integrates several components which are traditionally treated separately: photovoltaic generation, BESS storage, participation in flexibility markets and ancillary services, infrastructure for electric mobility, high-performance computing capacity — such as GPU clusters or an edge data center — and energy communities.

The basic idea is simple: green energy produced locally must be consumed, stored, optimized and monetized as efficiently as possible. Today, at both national and European level, there are more and more situations in which renewable energy cannot be absorbed or used optimally because of grid limitations, lack of storage, or the imbalance between production and consumption.

LIMES-X aims to respond precisely to this problem. The platform seeks to capture as much as possible of the renewable energy that would otherwise be lost or sold at a low value and give it a higher value-added use: storage, local consumption, powering digital infrastructure, electric charging, flexibility services and energy communities.

A standalone photovoltaic park has limited value and is exposed to market volatility. But a photovoltaic park integrated with storage, with an on-site digital consumer, with the possibility of participating in flexibility services, with charging infrastructure for electric fleets and with a local energy community becomes a much more robust platform.

LIMES-X is not just an energy generation project. It is an architecture through which renewable energy becomes local economic infrastructure and, at the same time, a tool for reducing pressure on overloaded grids.

 

Why does Romania need such a model now?

Because several trends are converging at the same time.

The first is the accelerated growth of renewable generation. This is a positive development, but without storage, flexibility and smart consumption, the system quickly runs into technical and economic limits. It is not enough to produce green energy; we must be able to integrate it efficiently.

The second is the growing pressure on grids. Energy grids in Romania and across Europe were built for a different system logic: centralized generation, relatively predictable flows and distributed consumption in a way that differs from what we see today. Now, with the massive emergence of renewable generation, prosumers, new consumption patterns and the electrification of transport, grids are being forced to manage much more complex flows.

The third is the growing need for digital infrastructure. Artificial intelligence, cloud services, data processing and industrial applications require computing capacity. This computing capacity needs energy, and there is increasing pressure for that energy to be clean, predictable and verifiable.

The fourth is the need for local development. Municipalities, industrial areas, farmers, companies and communities need solutions that do not merely produce energy, but create local value: recurring revenues, more predictable energy costs, better energy services and broader access to green energy.

Romania has an important advantage: there are decommissioned or underutilized industrial sites, land with energy potential, agricultural areas with relevant consumption and local generation potential, some with existing energy infrastructure or proximity to important grid connection points. These sites can become clean energy and digital infrastructure nodes, if they are developed in an integrated way.

 

How is CRC ENERGY’s activity connected to the development of LIMES-X?

CRC ENERGY today covers an important part of the EPC value chain for renewable energy and electrical infrastructure: design, execution, grid connection, medium- and low-voltage works, photovoltaic systems and storage solutions.

We work with municipalities, commercial and industrial clients, farmers and beneficiaries who need energy solutions adapted to their real consumption. We manage technical documentation, permitting processes and implementation, and our practical experience comes from direct contact with the reality of projects: deadlines, standards, grid connections, interaction with distribution system operators and the integration of equipment in the field.

Agriculture is a very important area in this equation. Farms, irrigation systems, storage facilities, agricultural processing and seasonal consumption can benefit from photovoltaic solutions, storage and energy optimization. At the same time, many agricultural areas can become part of a smarter energy infrastructure, in which local production, consumption and storage are correlated.

This experience is important for LIMES-X because an integrated energy hub cannot be built only from an investment presentation. You need the capacity to take the project from concept to permits, from design to execution, and from grid connection to operation.

LIMES-X is the platform that takes this experience further, into an integrated architecture. We are not talking only about building an energy asset, but about connecting several assets into a system that can generate long-term value and make better use of the renewable energy that is currently lost, curtailed or undervalued.

 

What is the logic of the Deva pilot project?

Deva is relevant because it illustrates very well the type of site we consider strategic: an area with an industrial history, existing infrastructure, grid connection potential and good positioning for the development of energy and digital services.

In such a location, we do not want to develop just a photovoltaic park. We want to build a hub in which energy generation, storage, local consumption, flexibility, electric mobility and digital infrastructure work together.

The role of the pilot project is to validate the model: technically, commercially, from an investment perspective and operationally. After validation, the strategy is to replicate it in other regional centers, adapted to the local specifics of the grid, land availability, consumption profile and demand for energy services.

Deva is the first step in demonstrating that this model can work not only as an idea, but as real infrastructure. The stake is not only energy production, but the ability to create a local system that consumes, stores and intelligently monetizes renewable energy, while also reducing pressure on the grid.

 

What is the investment case for LIMES-X?

The main rationale is not the yield of a single asset, but the value of a platform that combines multiple revenue streams and solves a systemic problem: renewable energy that is not used to its full potential.

A BESS system can generate revenues from flexibility and ancillary services. A photovoltaic park can support PPA-type contracts. A data center or high-performance computing infrastructure can generate recurring revenues from colocation or processing services. An electric mobility hub can monetize logistics flows and heavy transport. An energy community can bring stability, local acceptance and a collective consumption model.

Taken separately, each of these assets has its own risks. Integrated, they can create a more balanced portfolio, in which locally produced energy is monetized in multiple ways and grid infrastructure is used more efficiently.

For investors, the value comes not only from generation, but from the platform’s ability to transform green energy into value-added services: flexibility, digital consumption, electric mobility, energy for communities and solutions for industrial, agricultural or municipal clients.

The second important element is the scarcity of sites. Sites with available land, clear industrial zoning and existing or accessible electrical connections are not infinite. In the coming years, these locations will become increasingly valuable as competition for grid connection, flexibility and clean energy consumption grows.

An integrated energy hub is not just the sum of its assets. Value emerges from the relationships between them: how energy is produced, how it is stored, where it is consumed, when it is monetized on the market and how the benefit returns to the community.

 

How do you include data centers and GPU infrastructure in energy projects?

Because digital infrastructure is becoming one of the most important energy consumers of the next decade. Artificial intelligence, data processing, industrial applications and cloud services need computing capacity, and this capacity has two major requirements: access to competitive energy and traceability of the source.

If you have on-site renewable generation, on-site storage and digital consumption on the same site, you can build a much more transparent model. The energy is not merely “green” through an accounting mechanism; it is produced, stored and consumed within a verifiable architecture.

In addition, digital infrastructure can become a valuable consumer for renewable energy that would otherwise be difficult to integrate into the grid. Instead of part of the green generation being lost, curtailed or sold at very low prices during periods of overproduction, it can be used locally for high value-added digital services.

BESS has a dual role here. On the one hand, it stabilizes the relationship between variable photovoltaic generation and the more constant consumption of digital infrastructure. On the other hand, it can participate in flexibility markets when technical and commercial conditions allow.

This is one of the directions in which we see the convergence of energy and digital: not as two separate industries, but as two parts of the same critical infrastructure.

 

What role does electric mobility play in this model?

Electric mobility is a natural component of an integrated energy hub, especially when we talk about fleets, heavy transport and logistics corridors. Transport electrification does not mean only installing charging points, but integrating them into an energy system that can manage large loads, consumption peaks and the need for predictability.

A LIMES-X hub can support charging infrastructure for electric fleets, commercial transport or vehicles operating on major traffic corridors. The difference compared with an isolated charging station is that the energy can come from local generation, can be supported by storage and can be optimized according to the consumption of the other components of the platform.

Thus, electric mobility is not treated separately, but as part of the same ecosystem: generation, storage, consumption, flexibility and local services. In such a model, renewable energy is not pushed into the grid regardless of conditions, but directed towards useful loads, reducing pressure on energy infrastructure.

 

Is there, or will there be, room for energy communities in the LIMES-X platform?

Energy communities are the component that connects the hub with the territory. Without this component, an energy project risks remaining an isolated industrial asset. With an energy community, it can become an instrument of local development.

Until now, access to green energy has been easier for those who had a house, a suitable roof and the ability to invest in a photovoltaic system. But many consumers are not in this situation: they live in apartment buildings, have small spaces, are SMEs, schools, public institutions, farmers or consumers who cannot become individual prosumers.

An energy community changes this logic. Members can participate collectively in the generation, storage and consumption of green energy. Within LIMES-X, part of the energy produced by the hub can be allocated to the community, storage can optimize consumption, and the surplus can be monetized intelligently.

For us, the energy community is not a decorative element. It is the mechanism through which the energy transition becomes more accessible, more local and more socially accepted. At the same time, it is a way for renewable energy to be consumed closer to where it is produced, which reduces losses, congestion and pressure on the grid.

 

How realistic is it to see such communities functioning in Romania? How soon?

It is realistic, but it must be said clearly that this is not a simple process. The European framework exists, the legislative direction exists, and Romania has taken steps in this area. At the same time, further clarifications are needed regarding settlement mechanisms, actual operation, the relationship with suppliers and distribution system operators, as well as how benefits are concretely transferred to members.

We see energy communities as a strategic direction, not as a marketing message. We are working to integrate this component into LIMES-X projects and to demonstrate that an energy community can function within a sound technical and economic model.

Romania needs demonstrator projects, not just concepts. And our objective is for LIMES-X to be one of the platforms contributing to this demonstration, using renewable energy in a more efficient, more local and more valuable way for communities.

 

LIMES-X is a product made in Romania. What is the implementation strategy — is it only about Romania, or primarily about Romania?

Romania is the natural starting point for this model. On the one hand, we have real flexibility needs, a grid that must be prepared for more renewable generation and new loads, but also many industrial sites that can be reconverted.

On the other hand, Romania has an important regional position and can become a relevant hub for energy and digital infrastructure. We have areas with solar potential, existing industrial connections, municipalities looking for energy independence solutions, farmers who can integrate energy production and consumption into their activity, and a market that is beginning to understand the value of storage.

Our strategy is to validate the model here, in Romania, and then replicate it in other regional centers. Deva is the pilot project, and in the next stage we are analyzing hubs adapted to the local specifics of other areas, such as Timișoara and Cluj-Napoca.

We do not believe in a model copied mechanically from one city to another. Each hub must be configured according to the grid, land, consumption, local authorities and commercial opportunities. But the basic architecture — generation, storage, smart consumption, digital infrastructure and community — can be replicated.

In the long term, we see LIMES-X as a model that can contribute to a more efficient use of renewable energy in Romania and in Europe, reducing the economic losses associated with unmonetized energy and the pressure on existing grids.

 

What is the biggest obstacle to developing such a project?

The biggest obstacle is not technical. The technology exists: photovoltaic panels, batteries, energy management systems, digital infrastructure, metering solutions and software platforms. The real challenge is integration.

The energy market is still very fragmented. Developers think in terms of generation projects, investors analyze separate assets, municipalities look at things from the perspective of local needs, farmers view their consumption through the logic of their own activity, and the digital sector has its own decision-making criteria. LIMES-X tries to bring all these perspectives into a common model.

At first glance, such a project may seem complex. But complexity should not be avoided if it reflects the reality of the system. The grid, consumption, storage, mobility, digitalization and local communities can no longer be treated separately.

The energy transition is entering a stage in which the advantage will belong to those who can integrate. Not only to those who produce energy, but to those who can store it, consume it, monetize it and transform it into useful services for the economy and communities.

 

What should developers, investors, city hall officials and other potential LIMES-X partners and beneficiaries know?

For developers, my message is simple: stop building isolated assets. A standalone photovoltaic park is increasingly exposed to volatility, grid limitations and price competition. Defensible value emerges when generation is integrated with storage, consumption, flexibility services and local anchoring.

For investors, I believe this is the time to look closely at underutilized industrial and energy sites. Many of them are still assessed today through the logic of the past, not through the potential of the future. A site with grid access, available land and good positioning can become a strategic asset in an electrified and digitalized economy.

For municipalities, the opportunity is even more direct. Industrial land, proximity to the grid and the need for local revenues can be transformed into an energy development model. Through partnership with a serious integrator, an unused asset can become a source of revenue, local infrastructure and an instrument of energy independence.

For farmers, energy becomes a strategic component of competitiveness. Farms, irrigation systems, cold storage facilities, agricultural processing and seasonal consumption can benefit from local generation, storage and energy optimization. Agriculture has the potential to become not only an energy consumer, but an active participant in the new energy infrastructure.

And for citizens, energy communities can open a more accessible path towards green energy. Not everyone can become an individual prosumer, but many more people can become participants in a collective model.

This is the stake of LIMES-X: to move from separate energy projects to integrated platforms capable of producing clean energy, storing it, consuming it intelligently and creating local value. At the same time, LIMES-X aims to monetize as much as possible of the renewable energy that is currently lost or remains underutilized and to reduce pressure on Romania’s and Europe’s overloaded and ageing grids.
