Vitalii Nykolaienko, CEO of VOLTAGE Group, on energy independence, adaptation during wartime, operating on the EU market, and the future of Ukraine’s power sector.


Energy as national security


— What does energy independence mean to you personally?

— For me, as a company leader and a power engineer by profession, energy independence is not a political slogan. It is a concrete, technically measurable ability of a state to secure its own energy supply through domestic generation, without critical dependence on imports, without blackmail and vulnerability.

It means that we always have generation capacity, grid infrastructure, system balancing, and demand-side management at our disposal. It means Ukrainian power plants are fueling the Ukrainian economy, not weak points undermining our stability.

Personally, it is also an emotional matter. After more than 20 years of building energy infrastructure from scratch — power transmission lines, substations, generation facilities — you realize this is the true foundation of the economy and statehood. Without electricity there is no healthcare, communications, water, or defense. It is the nervous system of the nation. And it must be Ukrainian: strong, smart, and resilient.

Given our proximity to an aggressor, we need a significant reserve of distributed generation capacity with the ability to export into the EU.


Energy as a front line


— How has the role of energy changed during the war? Can we say it has become a factor of survival for business?

— In wartime, the energy sector has ceased to be a “normal” industry. It has become a separate frontline. Invisible, but critically important.

When a missile hits a transformer substation, it is not only an attack on a facility — it is a blow to the entire economy, to hospitals, education, businesses, tax revenues, and to homes where people sit in freezing temperatures. The war has made it clear: the power system is not about comfort, it is about survival.

For business, this became a shock and a turning point. Those who had never thought about backup power are now building their own micro power plants, installing PV modules, battery energy storage systems (BESS), diesel generators, and cogeneration units. Because a power outage means a complete halt of operations.

At the same time, respect for energy professionals has grown. We have seen that they are not “just workers in helmets” but true heroes, restoring power lines under fire, risking their lives. Some are developing strategies to protect infrastructure from attacks, others are implementing these strategies on the ground. And I am proud that our entire team at VOLTAGE Group is part of this strength.

Awakening to autonomous energy


— In your opinion, how much have Ukrainian companies realized the value of autonomous energy solutions?

— The years 2022–2023 became a moment of great awakening for Ukrainian business. What used to be optional — autonomous solutions for remote facilities or green projects — has now become a matter of strategic security.

Many companies have realized that they can and must invest in their own energy independence. We see rapid growth in demand for backup power systems, BESS solutions, rooftop PV, and CHP units. Not only from an economic perspective, but also in terms of stability and reliability.

But there is still much work ahead. At VOLTAGE Group, we emphasize that energy independence today means not only autonomy, but also responsibility — for your team, your business, your community. It is a contribution to the resilience of the entire power system. And it is from such solutions that we build a modern Ukrainian energy sector.


Who we are: VOLTAGE Group


— What is VOLTAGE Group?

— VOLTAGE Group is an engineering company operating in Ukraine and the EU. We design and construct energy infrastructure: electrical grids from 0.4 kV to 150 kV, solar and wind power plants, battery storage systems, and cogeneration plants. Since 2009, we have delivered hundreds of megawatts of capacity and are among the leading players in the renewable energy sector.

VOLTAGE Group is like a non-stop express train. You board at the station “Idea” and get off at the station “Completed Project” — fast, organized, without unnecessary delays.

— What does it mean to be a full-cycle EPC company in your case?

— EPC (Engineering, Procurement, Construction) means we take on all stages of an energy project:

  • Engineering — design and optimization of technical solutions.

  • Procurement — supply of equipment and materials.

  • Construction — civil works, installation, and commissioning.

The advantage is a turnkey project, without gaps between stages or contractors.

— How do you integrate design, construction, commissioning, and service?

— All our processes are united in one vertically integrated system. Designers, power engineers, and service engineers work as one team. Decisions and changes are instantly transmitted between departments. Operability and maintainability are embedded already at the design stage, reducing the client’s long-term costs.

— Why is it more beneficial for businesses to work with a single partner rather than with multiple contractors?

— Single-point responsibility eliminates “grey zones” where contractors shift blame to each other. Speed ensures no loss of time. Quality is guaranteed by standards controlled at every stage. Predictability allows the client to have a clear view of budget and timelines from day one.


Keeping the lights on in the darkest times


— How did VOLTAGE Group adapt to full-scale war?

Adaptability means the ability to withstand and continue working during wartime. At first, there was shock, like for everyone. Then our team began making crisis decisions, first of all about people’s safety. From the first days, together with business communities, we supported the Armed Forces of Ukraine and territorial defense. That gave enormous faith that we would endure as a state.

I promised to be the last to leave the office. That strengthened confidence within the company. We continued operations at running power plants, and soon after, resumed construction of projects that had been halted. Later, after missile attacks on the power system, everyone understood that voltage in a socket is of immense value. We delivered dozens of projects to provide industrial enterprises with autonomous power supply.

— What risks do you face today?

The concept of “risk” has changed. It feels now that every investment project we once debated before February 24, 2022, should have been executed without hesitation.

In business, risk is guaranteed; profit is not.

Current risk factors include:

  • Logistic delays due to restricted transport routes and customs procedures.

  • Instability of the power system and possible emergency outages.

  • Safety risks at construction sites, particularly in regions near combat zones.

  • Currency fluctuations and changing import conditions for equipment.

But compared to the main risks — threats to human life and physical destruction of facilities from drone or missile strikes — these are not critical.

Projects of rapid adaptation


— Which VOLTAGE Group projects best illustrate fast adaptation and effective response under crisis?

— During heavy missile attacks and emergency outages, we had to integrate high-capacity diesel generators into an industrial enterprise’s power system. Deadlines were extremely tight: the factory was shut down for only 24 hours to reconstruct internal networks. Every hour of downtime meant major losses. The team worked around the clock in switchgear rooms and managed to complete and launch the system on time.

— Another project involved rearranging 10 kV internal grids — about 30 km of cabling. Deadlines were tight, but we managed. The task was fully completed.

— While building solar plants on poultry farms, we had to work only during specific sanitary “windows.” Missing them meant a three-week generation delay. For multi-megawatt facilities in summer, this would have been serious losses. We adapted to that schedule and commissioned generation on time.

— VOLTAGE Group commissioned a 20 MW/40 MWh battery storage system as part of the largest BESS complex in Ukraine in just 4 months. This completed project is unique for Ukraine and widely discussed in the industry. At the same time, we are EPC contractor for 9 MW and 11 MW cogeneration projects. Deadlines are again accelerated, but we will deliver: we have learned to structure processes and we have a team that can plan and act on site.

— This year we also started operations in Europe. We are delivering a solar park in France. The client insisted that the same team which successfully completed projects in Italy should work here. For us, this is a sign of trust. And trust is the core value of VOLTAGE Group. We will not let our partners down.


Transparency and development


— How does the company ensure transparency for clients, and where is it heading today?

Transparency and control: VOLTAGE Group clients always have access to the real status of their projects — photos, videos, regular updates, and online dashboards showing live progress. Contracts specify clear deadlines and technical parameters, and schedules are shared as a joint monitoring tool. We work on facts and transparency, not promises. After commissioning, we remain close — providing service and support to keep systems running reliably.

Our clients are companies for whom electricity is mission-critical: factories, processing plants, agribusiness, logistics. Our energy security solutions help maintain stability even during emergency outages caused by attacks on the power system. Properly implemented engineering measures at each site reinforce the country’s resilience.

For security reasons, we do not disclose specific sites and clients. But we believe that in time we will be able to present a full reference list of completed works.

Meanwhile, we are expanding actively in Europe. We have opened an office in Warsaw, completed projects in Italy, Latvia, and France, and are negotiating several more. The EU market offers huge opportunities, but experience in Ukraine does not automatically guarantee compliance with European qualification standards. Here, everything must start from scratch: studying regulations, adapting to new frameworks, building trust. Step by step, we are doing it — expanding our presence and strengthening our expertise.


Values: trust, partnership, people


— What does trust mean to you, and how do you view partnership?

— For me, trust is the foundation of relationships and the core value of VOLTAGE Group. It means sharing knowledge, taking responsibility, and delivering on promises even in the hardest times. That is how true partnership is built.

I see partnership as a path to new opportunities. Alone you may move quickly, but together with partners you cross entire continents. It is like an architectural structure where each block is solid, and trust is the cement that holds it all together. Or like an orchestra, where only collective sound creates harmony. For VOLTAGE Group, this is the way to scale and to build a common future where the success of one becomes the success of all.


Personal


— What motivates you in such a demanding industry?

— To create value that works both for the client and for the country. Each project is a brick in the foundation of a strong and independent economy. Energy is the circulatory system of the state, and every day we inject new energy of development into it. The greatest capital of VOLTAGE Group is our people. Their work strengthens the country — and that is what motivates me.

— How has your vision of leadership changed?

— The war has taught me that a leader must stay close to the team, support them in difficult moments, and inspire belief even when times are hard. For me today, leadership is about humanity, resilience, and responsibility.

— Where do you see VOLTAGE Group in five years?

— As an international company with a Ukrainian heart. We want our employees to be proud of their work — both at home and abroad. Their projects will change the world while strengthening Ukraine. Under peaceful skies, we will channel energy into investment projects, showing the world that Ukraine can not only fight but also develop, innovate, and succeed.
