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.

Regional webinar on gender-responsive energy transition and workforce empowerment

A regional webinar titled Gender-responsive Energy Transition and Workforce Empowerment in the Western Balkans will be held on May 22. The aim of the webinar, organized by GIZ, is to initiate a dialogue on the social and gender aspects of the transition from fossil fuels to renewable energy sources.

The energy transition in the Western Balkans is bringing significant changes. The shift to renewable energy leads to a restructuring of the labor market. More than 138,000 jobs are currently linked to coal-based industries, raising questions about the social impacts and the need for workforce reskilling.

Investing in skill development and workforce adaptation is essential to mitigating social challenges, particularly gender inequalities, during the energy transition process.

GIZ recently conducted the first comprehensive analysis of the impact of the energy transition on the labor market in the Western Balkans. The study outlines the expected job losses and gains, identifies the skills needed for future employment in the renewable energy sector, and highlights the crucial role of technical and vocational education in this process.

Everyone interested can register via a link

The the findings of the study will be presented at the webinar Gender-responsive Energy Transition and Workforce Empowerment in the Western Balkans, scheduled for May 22 from 14:00 to 15:30. The event will be held online via Microsoft Teams, and all interested participants can register via this link.

The discussion will feature Valentina Vučković, a socio-economic expert from the Institute for Development and International Relations (IRMO), who will present the research findings. Fiona Imami from the organization Co-Plan will speak about policy solutions for coal mine regions within the concept of a just transition, and Marta Schulte-Fischedick from the Energy Community Secretariat will address gender inequality issues and potential systemic solutions.

Special emphasis will be placed on the need for greater synergy between the education and energy sectors to ensure that the workforce can effectively adapt to new conditions. The discussion will also cover issues of gender equality, the inclusion of women in the green energy sector, and ways to reduce existing gender disparities in employment and career advancement in the field.

Wind farm project in Cyprus rejected to protect birds, habitats

The Department of Environment of Cyprus scrapped a proposal for a wind power plant partly within or near protected areas due to the expected impact, including on vulnerable bird species such as the Bonelli eagle and long-legged buzzard. The project was launched in 2008 and amended several times.

Stivo Trading and its wind farm project in Cyprus failed to renew a temporary planning approval. The developer initially proposed 33 turbines of 49.5 MW in total, the domestic press reported.

Since 2008, when the project was launched, it was amended several times. The final version, from 2023, is for just four wind turbines instead of the previous ten, and a capacity of 18 MW, down from 22.5 MW.

Irreversible impact on Natura 2000 zones

The sites are within and near the Panagia Stazousa River special protection area and as close as one kilometer from the Stavrovouni forest, designated a special area of conservation.

The locations belong to the local communities of Pyrga, Klavdia and Alethriko. The Department of Environment said it expects that the investment would directly, negatively and irreversibly impact the Natura 2000 zones. It includes vulnerable species, habitats and conservation objectives.

Environmental authority highlights risk to birds from collisions, electrocution

Sensitive species would be displaced and their populations reduced, the update reads. The environmental authority also highlighted the risk to birds from collisions and electrocution.

It pointed to a cumulative impact from supporting infrastructure and the existing projects. In the wider area there are four wind power plants, of which the one in the northeast is in the Panagia Stazousa River special protection area. West of Stivo Trading’s zone, the fifth one, is a nesting area.

The department highlighted the Bonelli eagle, long-legged buzzard, the European roller and thrush, among other birds. At least three Bonelli’s eagles died in collisions with energy infrastructure and another five by electrocution.

Hidroelectrica picks contractor for PV systems on 20 hydropower plants

Romanian state-owned hydropower plant operator Hidroelectrica signed a deal with Servelect and subcontractor Electroplus, which need to install solar panels on the roofs of 20 hydroelectric plants. They are on the middle and downstream parts of the Olt river.

Combining hydropower with photovoltaics including floating solar power plants is becoming popular. The two sources are compatible, especially if there is a dam, as it can save water in reservoirs. The grid infrastructure for PV panels is already there and there are usually no land ownership issues. Hidroelectrica, which mostly operates hydropower plants, is about to solarize its existing facilities.

The Romanian state-owned company pursuing diversification signed an agreement with Servelect and its subcontractor Electroplus. There were four bids in the tender.

First solar power project for Hidroelectrica

Solar power systems will be on the roofs of 20 hydropower units on the middle and downstream sections of the Olt river. Hidroelectrica, listed at the Bucharest Stock Exchange since 2023, turnkey deal, said it aims to optimize production costs. However, it didn’t reveal whether it would operate the colocated assets jointly, as hybrid power plants.

Hidroelectrica is the largest electricity producer in the country, but it will be its first solar power units. The deal, for an overall 2.96 MW, is worth EUR 1.77 million excluding value-added tax. The deadline is 24 months, of which four months for the design.

Servelect, Electroplus responsible for all phases from procurement to commissioning

The utility also tasked the two firms, based in Cluj-Napoca, with manufacturing and procurement, transportation, testing and commissioning. The PV systems would consist of 620 W panels and 100 kW inverters. Hidroelectrica estimated the combined annual output at 3.71 GWh.

The company operates 188 hydropower plants, 6.4 GW overall, and the Crucea Nord wind park of 108 MW. Earlier, Hidroelectrica and Masdar were considering a pilot project, under an upcoming joint venture, for floating solar power plants on seven reservoirs, also on the Olt.

Servelect is active in engineering and energy services. It was founded in 2005. Electroplus, which handles electrical installations, operates since 2001.

Works beginning on North Macedonian side of gas interconnector with Greece

The North Macedonian section of the gas interconnector with Greece is expected to be completed by early 2027. The construction contract was signed by the Ministry of Energy, Mining and Mineral Resources, domestic contractor Rapid Build and the country’s gas transmission system operator Nomagas.

The construction of the gas pipeline connecting North Macedonia with Greece is set to begin in a month, according to officials. Land expropriation is 90% complete. The initial capacity of the interconnector would be 1.5 billion cubic meters per year, with a potential to double it. The works are expected to be completed within 22 months.

„With the signing of the contract for the construction of the Macedonian section of the gas interconnector with Greece, we are marking the beginning of the largest energy investment in North Macedonia in the last ten years. The interconnector is proof that when there is political will, regional trust, and professional dedication – the results are real and tangible,” said Minister of Energy, Mining and Mineral Resources Sanja Božinovska.

The contract was signed by the ministry, contractor Rapid bild, based in Kumanovo in North Macedonia, and the country’s gas transmission system operator Nomagas. The future pipeline would be able to carry both natural gas and hydrogen.

Repeated tender slashes price by EUR 12 million

The winning bid was EUR 59.9 million or EUR 12 million less than in the initial tender, which was annulled.

The project is worth over MKD 5.1 billion (EUR 82.9 million). It is financed by the European Investment Bank (EIB) and the European Bank for Reconstruction and Development (EBRD). It includes grants of EUR 2.5 million for technical assistance and another EUR 9.9 million via the Western Balkans Investment Framework (WBIF).

The project is financed by the EIB and EBRD

„This contract ensures diversification and access to a greater number of natural gas sources, enables economic development, progress and environmental protection, and contributes to the security of energy supply,” said Executive Director of Nomagas Muhamet Elmazi.

Gasification would significantly improve air quality, especially in areas where wood and fuel oil are currently used for heating.

Greek section of interconnector under construction since February

On the North Macedonian side, the interconnector route is 68 kilometers long, out of a total of 123 kilometers. It will run from Nea Mesimvria in Greece through Evzoni (Mačukovo) and Gevgelija at the border, to Negotino. The next phase involves building gas links from Gostivar to Kičevo (34 kilometers) and from Sveti Nikole to Veles (28 kilometers).

Greek company Terna began constructing its country’s section of the pipeline in February.

Nomagas and Greece’s National Natural Gas System Operator (DESFA) made their final investment decision a year and a half ago.

The companies leaned the investment on the project for the Alexandroupolis LNG Terminal. The liquefied natural gas facility in northeastern Greece was opened on October 1. However, due to a malfunction, it has been out of operation for more than three months. According to the latest update, gradual reactivation is expected to begin by the end of May.

Weakness in Serbian energy system is no option

Serbia’s state-owned power utility Elektroprivreda Srbije (EPS) is committed to its own and the country’s goals for green energy and emission cuts, but it is sustainable only if it doesn’t jeopardize energy security, Chief Executive Officer Dušan Živković said. Weakness in the energy system is not an option, he underscored.

The recent blackout in entire Spain and Portugal and the one last year in the Balkans have imposed the topic of large energy storage facilities which would support the integration of renewables, CEO of EPS Dušan Živković said at Belgrade Energy Forum (BEF 2025). The company is committed to its own and the country’s goals for green energy and emission cuts, he asserted.

“We will work on that, of course, believing in these objectives, but without compromising energy security and the energy sovereignty of the state of Serbia. It was proven to be the only sustainable path and that if we don’t follow it, it can result in situations that are not a good message toward consumers, and they are not a good message toward investors either. Weakness in the energy system is certainly not an option”, Živković stated.

In its Integrated National Energy and Climate Plan (INECP or NECP), Serbia is targeting for 2030 a 45.2% share of renewable energy sources in electricity production and a decrease of greenhouse gases by 40.3% from the 1990 level.

Decarbonization is not easy without serious storage

Among its other activities, EPS is working on its small green energy projects on open cast coal mines, while the strategic partner, a consortium of UGT Renewables (UGTR) and Hyundai Engineering, is tasked with building a group of solar power plants of 1 GW in combined connection capacity alongside 200 MW of battery energy storage, and transfer them to Serbia’s government-controlled power utility, Živković noted. But the process of decarbonization with necessary renewable energy capacity won’t be easy “without serious storage,” he stressed.

Serbia hosts fossil fuel power plants of 4 GW in total

Big energy storage projects are financially challenging, only marginally cost effective, and they are not easy to build, EPS’s head claims. They are necessary to be able to draw enough baseload energy, and in Serbia they need to contribute replacing a large fossil fuel capacity – currently it amounts to 4 GW, Živković said.

Pumped storage hydropower project Bistrica, existing facility Bajina Bašta enable comfort for signing PPAs

EPS primarily focuses on the Bistrica pumped storage hydropower project and the possibility to develop the one for Đerdap 3, he added. That way conditions would be created for the facilities to provide new services in the market, so “the region feels safer, too,” Živković underscored.

Counting on Bistrica and the existing pumped storage hydropower plant, Bajina Bašta, EPS is in “a comfortable zone” for signing power purchase agreements (PPA) with companies for their green power plants, Živković explained. Bajina Bašta is undergoing the second half of reconstruction works.

Turning back to the April 28 collapse of the Iberian electricity system, Živković pointed to the adverse interest of private investors – get profit in the short term – and companies responsible for energy security. In his view, it is necessary to act “more intergenerationally responsibly” and very important to find balance in relation to profits.

BiH laying groundwork for battery energy storage systems

Bosnia and Herzegovina is set to have its first battery energy storage systems installed in the transmission network, which will provide auxiliary services.

The State Electricity Regulatory Commission is drafting a decision to allow battery energy storage systems (BESS) to offer secondary frequency regulation, Mirza Kušljugić, a member of the Board of the Regional Center for Sustainable Energy Transition (RESET) from BiH, said at Belgrade Energy Forum 2025 (BEF 2025).

Since such a decision does not require a lengthy regulatory procedure, and the balancing market is already regulated, batteries could be installed very soon, he noted.

“I anticipate that private investors will take the lead in this initiative,” Kušljugić added.

He stressed the importance of experimenting with new technologies, noting that batteries represent a technology that can fundamentally transform the energy paradigm.

To be economically viable, batteries must serve multiple functions

The cost of batteries has significantly decreased in recent years. For instance, prices fell by 40% last year and have decreased by an additional 5% so far this year.

According to Kušljugić, batteries should not be limited to providing arbitrage but should also perform additional roles.

“Batteries come in various sizes – small, medium, and large – each with specific functions. They can regulate voltage or enable a black start, especially when equipped with new grid-forming inverters. This is a disruptive technology. It doesn’t matter whether it is installed on the transmission grid, the distribution grid, or behind the meter,” noted Kušljugić, who moderated the BEF panel titled Energy revolution underway – uniting efforts to deliver green, intelligent and sustainable energy solutions.

He added that batteries in the transmission system need to perform two or more functions, including frequency regulation.

Behind-the-meter batteries are also on the way

Historically, secondary regulation in BiH has been provided by any entity capable of offering flexibility, typically through tenders. So far, the service has mostly been provided by hydropower plants. However, due to lower nighttime prices, their operators were not interested in continuing to supply the service, leading to a shortage of secondary regulation. Batteries now have the potential to fill this gap.

Kušljugić believes that batteries installed behind electricity meters will soon become a reality in BiH as well. Currently, there are 300 to 350 MW of solar power capacities installed on the roofs of business premises, but their owners cannot feed excess electricity into the grid. It is only a matter of time before battery prices decrease enough to facilitate their installation, he underlined.

RESET, which advocates for citizen energy and prosumers, suggests that all solar installations should now be equipped with hybrid inverters, making them ready for future battery integration.

This approach is essential for the distribution grid to be ready to integrate excess electricity, Kušljugić concluded.

North Macedonia adopts Law on Energy

With a majority of votes, 62 out of 120, the Assembly of North Macedonia adopted the Law on Energy. The government’s representatives say it is systemic, comprehensive, and reform-oriented legislation laying the foundation for the country’s new energy policy. The act aligns the country’s legal framework with the European Union.

The new Law on Energy will bring numerous benefits to the country and its energy future, according to the Government of North Macedonia. They include a liberalized, transparent and competitive electricity market ensuring fairer prices and more choice for consumers, the introduction of smart meters for more accurate consumption measurement, and daily insight for consumers into their electricity usage.

The law is compatible with the reform agenda for the Western Balkans and with EU directives. Its pillars are:

  • A significant increase in the share of renewable energy sources in final consumption;
  • Greater energy efficiency and reduction of losses;
  • An open energy market in which citizens become active participants – producers, sellers, and members of energy communities.

The law supports new concepts such as citizen energy communities and demand-side management models, increased market liquidity, and broader access to energy sources for the economy, along with equal investment opportunities.

It addresses infrastructure stability through investments in storage systems and their digitalization, as well as providing a stable, transparent, and predictable framework for domestic and foreign investors. The law strengthens the capacities of regulators and operators, creates conditions for greater integration with regional and European energy networks, and enables new investments in solar, wind and other renewable sources, district heating, gasification, storage and digitalized grid infrastructure.

Božinovska: New law paving way for energy sovereignty for Macedonia

Minister of Energy, Mining and Mineral Resources Sanja Božinovska said in parliament ahead of the vote that the Law on Energy is the foundation of the national transformation toward a clean, sustainable and fair energy future.

„This is a law that creates opportunities but also demands responsibility. Energy is not just the engine of the economy; it is the basis for a quality life. With this law, we are opening the door to an energy sovereign, green and European Macedonia. This law is more than a normative act – it is a signpost for the future. A chance we must not miss,” she said.

Transparent, predictable investment framework

The law includes provisions for protecting vulnerable groups, supporting the fight against energy poverty and ensuring fair access to energy for all.

According to the ministry, the law provides a stable, transparent and predictable framework for domestic and foreign investors.

All EU energy directives have been implemented, said President of the Energy, Water Services and Municipal Waste Management Services Regulatory Commission (ERC or RKE) Marko Bislimoski. Of note, yesterday he spoke at the Belgrade Energy Forum – BEF 2025, organized by Balkan Green Energy News.

The drafting process involved institutions, experts, the business community, operators and the national regulator. A total of 61 amendments were adopted.

Unlike the ruling majority, the Left (Levica), an opposition party, claimed the Law on Energy does not protect consumers or national interests. Out of 11 amendments that it submitted, only four were adopted. They include provisions aimed at protecting consumers from unrealistically high electricity bills.
