Alteo building solar park with battery storage for MOL Group

MOL’s 37.4 MW solar power plant with a battery energy storage system (BESS) of 40 MWh will contribute to the energy independence of its oil and gas complex in southern Hungary. Alteo is the contractor building the facility. The battery segment has received grants totaling EUR 20.5 million.

MOL Group marked the start of construction of a solar park and BESS at its Algyő site in Csongrád-Csanád county. The Hungarian company pointed out that smart green transition, reducing external energy consumption, is a key element of its Shape Tomorrow strategy.

The investment will significantly contribute to the energy independence of the oil and gas complex in southern Hungary, improve the flexibility of electricity supply and lower the site’s CO2 emissions by 13,000 tons per year, according to the announcement.

MOL Group hired Alteo, in which it holds minority stake

The photovoltaic plant project is for 37.4 MW and the battery energy storage system would have 40 MWh in capacity. Alteo, listed at the Budapest Stock Exchange, is the contractor for the construction of the facility. MOL Group, which holds a minority stake, controls a total of 73.8% of its shares together with two private equity funds.

The company’s full name is Alteo Energy Services. As an aggregator, it owns or operates gas power plants and renewables, combined with energy storage, while also providing software as a service (SaaS).

Storage is essential for smart energy transition

MOL has won support of EUR 20.5 million in total for the energy storage project in Algyő. A EUR 6.7 million grant came via the European Union’s Recovery and Resilience Facility (RRF) and Hungary’s National Recovery and Resilience Plan (NRRP), while the government secured the remainder.

“Our strategic goal is a smart energy transition, for which energy storage is essential, as it ensures the integration and flexible use of sustainable energy systems. Algyő is a symbolic location for us – it is here that six decades of industrial experience meet the technology of the future,” said Managing Director of MOL Exploration and Production Hungary Péter Archibald Schubert.

Solar power capacity in Hungary has topped 8 GW

The solar power plant’s output is equivalent to the annual consumption of 22,500 households in the county, while the BESS can flexibly cover 7,300 households, he added.

MOL Group operates seven solar parks in Hungary and two in Croatia, of 111 MW altogether. Its goal is to reach 200 MW in renewable energy capacity by the end of next year.

Alteo will operate MOL’s other battery energy storage system, in Tiszaújváros

Of note, the company broke ground in March for a 40 MWh battery system at the MOL Petrochemicals site in Tiszaújváros, in northeastern Hungary. It selected Alteo as its operator. The investment is worth EUR 16.3 million, of which EUR 6.7 million is a grant from NRRP.

As for the PV and battery investment in Algyő, the local authority made the 47-hectare site available to the integrated hydrocarbons producer, Hungarian media reported.

At the ceremony, Deputy State Secretary for Energy Transition at the Ministry of Energy Viktor Horváth said that the country’s solar power capacity has surpassed 8 GW. It is ninth in the world in PV capacity per capita.

In other storage news, MET Group inaugurated the largest BESS in Hungary last week at its gas power plant near Budapest.

Alteo’s Chikán: Aggregators have AI solutions for grid stability, production optimization (video)

Factors like power price volatility, the global shift in policy making and the need for flexible solutions for the integration of renewables are creating an important momentum for developers and aggregators, Chief Executive Officer of Alteo, Attila Chikán, said at Belgrade Energy Forum 2025. The company is expanding in Central and Southeastern Europe with investments in power plants and its AI-backed platform for operating third-party assets.

The electricity system needs to become more and more flexible to accommodate weather-dependent, intermittent sources – solar, wind and hydropower, Alteo’s CEO and Chairman of the Board Attila Chikán said and pointed out that the outage in Spain and Portugal on April 28 highlighted the need for investing in grid stability and upgrades.

In his keynote speech at Belgrade Energy Forum (BEF 2025), he stressed that a global shift in policy making in the sector, particularly in the United States and Europe, is bringing both challenges and opportunities. In Chikán’s view, the situation creates an important momentum for developers and aggregators.

[wpcc-iframe title=”Belgrade Energy Forum 2025 – Attila Chikan Jr., CEO and President of the Board, ALTEO Plc” width=”500″ height=”281″ src=”https://www.youtube.com/embed/FZCrhx8yh6E?feature=oembed” frameborder=”0″ allow=”accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share” referrerpolicy=”strict-origin-when-cross-origin” allowfullscreen=””]

“In the past five years we have seen a great deal of price volatility on the markets in the region. If you look into the future, taking into account the impact of the ambitious plans of regional countries to expand renewable power, one might expect even more pressure on balancing price volatility,” he asserted.

Role of international initiatives

Alteo’s CEO said tailored incentive mechanisms are essential for developing a balanced energy mix. There are also major endeavors on an international scale, Chikán added: connecting markets with diverse geographical characteristics, power plant portfolios and different supply-demand balances.

He explained that cross-border initiatives such as PICASSO and the Blue Sky project bring electricity exchanges in the region closer together. Interconnectors like the Pannonian Corridor and the proposed Black Sea green cable contribute to balancing and the management of energy price volatility, Chikán noted.

Future-proof tech solutions required for risk mitigation

In risk mitigation, the energy system’s stability benefits from future-proof technological solutions as well, namely smart metering, advanced weather forecasting and artificial intelligence–based production optimization, he said. This is where aggregator companies like Alteo come into the picture, its chief underscored.

As for its hardware, the company based in Budapest operates a diverse and balanced production portfolio of gas power plants and renewables, combined with storage, Chikán added.

Alteo runs a portfolio of gas power plants, renewables and storage facilities

“Sounds good, but without a well-designed and functional software, any hardware is purely a collection of materials. And even if they do operate, for sure they operate in a suboptimal way, without synchronization,” he stated.

That’s why Alteo developed its own production management platform, which it offers as a software-as-a-service (SaaS) solution as well. The company also supports the operation of 2 GW in third-party capacity, mostly photovoltaics.

“We optimize production in an automated way, using artificial intelligence, integrating real-time weather forecast data, capacity data and market data,” Chikán stressed.

The platform includes executing trading activities. The partners don’t have to deal with scheduling and the balancing energy costs, he said. The company makes a renewable electricity product closer to baseload, Alteo’s head asserted.

Slovakia, Croatia, Serbia are primary investment destinations in Alteo’s regional expansion

Early this year, the company unveiled a strategy for expansion in Hungary as well as into Slovakia, Croatia and Serbia as primary investment destinations. Alteo revealed it is interested in Poland, Czechia, Slovenia, Bosnia and Herzegovina, Montenegro and North Macedonia, too.

Chikán said it also aims to position itself in operations and maintenance (O&M), among other segments. Alteo is particularly seeking stable and reliable AI-based aggregator partnerships, he noted. The company has an investment target of up to EUR 3.5 billion by the end of the decade.

Belgrade Energy Forum 2025 – 50 speakers at eight panels to track pace of SEE energy transition

The agenda of the third Belgrade Energy Forum, taking place on May 14-15, has been finalized with the addition of further prominent energy experts and companies. The conference, organized by Southeast Europe’s leading energy news portal, Balkan Green Energy News, will feature eight panels covering key topics in the energy sector, with an impressive lineup of speakers. Make sure you register on time via this link.

The Belgrade Energy Forum will once again be a meeting place for representatives of regional and international institutions and organizations, as well as the business community from across the region, Europe, and the world.

Eight panels featuring more than 50 speakers will offer an overview of the current challenges in the energy sector. Conference participants will hear in-depth analyses of the current situation, but also projections for the future. The thread that connects everything at this year’s BEF is digitalization – it permeates energy production, consumption, and storage and allows enough flexibility for the stable functioning of the energy systems of the future, where renewable energy will dominate.

Chikán: Electricity knows no borders

One of the key speakers at the conference, Alteo Group CEO Chikán Attila, will lead the company’s high-level delegation. Alteo has recently launched a regional expansion drive, aiming to establish a green platform of up to 2 GW in energy production, including operation, software, maintenance, storage, and waste management.

The Hungarian company primarily targets its home market, Slovakia, Croatia, and Serbia.

“Electricity knows no borders, therefore partnerships and collaborations among energy market players are essential, even at the regional level. Such cooperation is vital to ensuring the security and reliability of electricity supply, facilitating the integration of renewable energy sources, and providing essential digital solutions, supported by expertise and professional know-how,” Chikán stressed.

Decarbonization strategies for power generation in Southeast Europe 2040/2050

  • Dejan Paravan, CEO, GEN Energija
  • Dušan Živković, CEO, EPS
  • Eric Scotto, CEO, AKUO
  • Milutin Đukanović, Chairman, EPCG Board of Directors
  • Neda Lazendić, Country Manager, WV-International

Although at the heart of national energy systems, state-owned power utilities are faced with an environment that has changed and continues to change rapidly. The key shift is the entry of private capital into electricity production through the construction of solar power plants and wind farms.

The energy transition, at this stage, requires cooperation between state power utilities and private companies. With decarbonization as the main objective, the key challenge lies in choosing appropriate strategies and electricity generation technologies.

Moderating the panel will be Dražen Jakšić, Director of the Energy Institute Hrvoje Požar (EIHP).

“The transition to a low-carbon energy system is a key challenge for our region, demanding innovation, investment, and cooperation. As a sponsor of the Belgrade Energy Forum, EIHP is committed to fostering dialogue and driving sustainable energy solutions. I look forward to an insightful discussion,” he stressed.

Jakšić: The transition to a low-carbon energy system is a key challenge for our region, demanding innovation, investment, and cooperation

In recent years, nuclear energy has emerged as a possible alternative. There is hardly a better interlocutor on this topic in the region than Dejan Paravan, the top man of GEN Energija, the Slovenian company developing the Krško 2 nuclear power plant project.

Dušan Živković, CEO of Elektroprivreda Srbije (EPS), will tell us about the Serbian power utility’s plans when it comes to nuclear energy.

Živković: Without decarbonization, the region’s energy sector has no future

“Without decarbonization, there is no future for the region’s energy sector, and that is the biggest challenge ahead of us. It is essential to accelerate decisions and ensure sustainable project financing mechanisms that will provide energy security for every country and power utility in the decades to come. By investing in existing capacities and new renewable energy projects, EPS, as the biggest utility in the region, will make its own contribution to energy security. That’s why we have initiated a transformation process – because we need to be more profitable, more efficient, and fully prepared to tackle any challenge,” Živković pointed out.

The energy transition, in his words, is the path EPS has chosen, and all its plans will align with that goal, based on the belief that the diversification of energy sources and new technologies are essential for achieving it. “These are just some of the key messages I will share with the participants of this year’s BEF,” said Živković.

Eric Scotto, co-founder and CEO of French company Akuo, will share the latest information on the energy transition from across the globe.

The company’s portfolio consists of 1.9 GW of power plants in operation and under construction, with a further 12 GW in the pipeline in more than 20 countries around the world, including a number of countries in the Southeast Europe region.

Integration of Western Balkans electricity markets into internal European market through market coupling

  • Anže Predovnik, Director, ADEX Group
  • Ivan Asanović, Executive Director, CGES
  • Marko Bislimoski, President, Energy, Water Services and Municipal Waste Management Services Regulatory Commission of the Republic of North Macedonia
  • Zoran Vujasinović, Policy Officer, ACER

The integration of the Western Balkans’ electricity markets with the European Union (EU) markets is a process that deserves much greater public attention than it currently receives. It is safe to say that its true importance will become evident only once it is completed.

Full integration will unlock significant synergies, maximizing the benefits of a unified market by enhancing supply security, accelerating the integration of renewable energy sources, and fostering greater competition and transparency.

Moderator Dejan Stojčevski, CTO of the SEEPEX power exchange, says the panel seeks to encourage dialogue on the importance of cross-border collaboration and market efficiency in bolstering energy security and sustainability in the region.

Bislimoski: The time for inspiring speeches is over. Geopolitical developments demand action – now!

Since market integration is largely the job of regulators, the challenges they face will be analyzed by Marko Bislimoski, president of North Macedonia’s Energy and Water Services Regulatory Commission (RKE).

He says that three things are essential for the regional integration of electricity markets into a single European market: investment, investment, and nothing but investment. In his words, the energy crisis demonstrated that limitations become a reality when governments fail to prioritize the implementation of key energy infrastructure capacities in their budgets.

“This past winter, the region faced the highest electricity prices compared to the rest of Europe. Why? Because the implementation of energy investments is not just a ribbon-cutting ceremony. Today, more than ever before, the countries of the former Yugoslavia must demonstrate maturity. These are the years when energy independence will be built through action. The time for inspiring speeches is over. Geopolitical developments demand action – now!” he stressed.

Energy revolution underway – uniting efforts to deliver green, intelligent and sustainable energy solutions

  • Aleš Prešern, VP, Head of Southeast Europe, Siemens Energy
  • Maja Turković, SVP, CWP Europe
  • Ann-Catherine de Tourtier, Managing Director Mediterranean, Nordex Group

As much as contesting the energy transition may be futile, there are still those who find such a view meaningful, especially in light of certain global political developments. That’s why it is important to give the floor to some of the transition leaders and let them testify that an energy revolution is indeed underway in the region.

The panel’s moderator Mirza Kušljugić – professor, energy expert, and one of the founders of Bosnia and Herzegovina’s Centre for Sustainable Energy Transition Centre (RESET) – goes one step further to show that change is not only happening but also accelerating.

“The key words are a new energy paradigm driven by the four Ds – decarbonization, digitalization, decentralization, and democratization. But now we also have another D: disruption, or radical change in the industry and market caused by technological innovation. Of course, we must focus the discussion – from global processes (China, the US, the EU, the Global South) to where the region stands in all of this,” Kušljugić points out, providing a perfect introduction to the panel.

Turković: It’s more important than ever to have open discussions about real solutions

Aleš Prešern, Vice President and Head of Southeast Europe at Siemens Energy, has worked in the energy sector for more than 20 years. He recalls that digitalization is key, along with grid resilience and electricity transmission.

With nearly 100,000 employees in more than 90 countries, Siemens Energy develops the energy systems of the future, ensuring that the growing energy demand of the global community is met reliably and sustainably. The technologies created in the company’s research departments and factories drive the energy transition and provide the base for one sixth of the world’s electricity generation.

As a leader in renewable energy development, CWP is actively working on several large-scale projects across the SEE region with a total capacity exceeding 7 GW, positioning the company at the forefront of the region’s energy transition. Given its global expertise and insights into the regional energy market, CWP’s contribution to this year’s conference will be invaluable.

Maja Turković, Executive Vice President of CWP Europe, says that BEF 2025 is a key gathering of leading experts driving the energy transition in Southeast Europe.

“As this shift gains momentum, it’s more important than ever to have open, action-driven discussions about real solutions to the challenges and opportunities ahead,” says Turković.

PPAs as a key to renewable energy growth in SEE

  • Nikola Gazdov, Chairman, Association for production, storage and trading of electricity – APSTE
  • Natalija Ljubić, Manager PPA & BESS Transactions, Pexapark
  • Ivana Đurović, Category Manager Renewable Energy, Knauf Group

Power Purchase Agreements (PPAs) are, like flexibility, a tool for fixing the imperfections of renewable energy sources, and they are recognized as a key mechanism within the new electricity market design. They ensure price stability, attract new investment, and accelerate the decarbonization of industry.

Is the region ready for PPAs? What are the dominant models? What is the current market practice? How are PPAs viewed by financial institutions? What do they offer to end consumers and what to investors in new power plants? Answers to these questions will be sought at the panel moderated by Mislav Slade-Šilović, Energy, Utilities & Resources Consulting Leader for Southeast Europe and member of the core PPA team at consultancy PwC.

Experience with PPAs for more than 500 GWh of electricity

Slade-Šilović’s experience in concluding PPAs for the production and consumption of over 500 GWh of electricity per year in the SEE region will certainly be of help.

Nikola Gazdov, Chairman of Bulgaria’s association for electricity production, storage, and trading (APSTE) and member of the Board of Directors of the European solar industry association SolarPower Europe, has no shortage of experience either. As CEO of three companies – Enery Element GmbH, Element Power Group, and Renergy – he is involved in the development of a large number of projects.

Pexapark, a company that provides logistics to businesses in the renewable energy market, is synonymous with PPAs in Europe. Natalija Ljubić is the Manager for PPA and BESS Transactions at Pexapark, which has helped conclude contracts for facilities with a combined capacity exceeding 35 GW.

The views of electricity buyers – without whom there would be no PPAs – will be conveyed by Ivana Đurović, Category Manager for Renewable Energy at Knauf Group.
