BEF 2025: Technologies for energy transition are here, getting cheaper every day
Technologies for the energy transition already exist, and their use is increasing thanks to falling costs. Investors and bankers claim they are ready to invest and that money isn’t an issue. The missing part are upgraded transmission grids, along with policies and regulations to integrate everything into a suitable environment, according to investors and lenders gathered at Belgrade Energy Forum 2025.
The third Belgrade Energy Forum, BEF 2025, welcomed four hundred participants from more than 30 countries from the region, Europe, and beyond. The two-day conference was organized by Balkan Green Energy News.
Participants in the panel Energy revolution underway – uniting efforts to deliver green, intelligent, and sustainable energy solutions were Maja Turković, Senior Vice President of CWP Europe, Aleš Prešern, Vice President and Head of Southeast Europe of Siemens Energy, and Christian Beynio, Head of Advisory of Kommunalkredit Austria AG.
According to panel moderator Mirza Kušljugić, a member of the Board of the Regional Center for Sustainable Energy Transition (RESET) from Bosnia and Herzegovina, the energy transition is actually a revolution, given the technological changes.
“The region is still burdened by tradition. We know the transition is inevitable, but we aren’t fully aware that it will be disruptive,” Kušljugić stated.
Technology is here, and so is financing
Maja Turković, Senior Vice President of CWP Europe, stressed that technology, currently undergoing a revolution, is the best card the world has in the transition. She even suggested that financing isn’t a problem and that there are more financial resources available than projects qualified to receive funding.
However, she is surprised by the rapid growth in solar power installations. Turković argued that market-based projects cannot achieve double-digit internal rates of return on equity. Part of the explanation may lie in the fact that panel prices have dropped by 60% over two years.
Battery prices have also fallen. The largest drop was last year, 40%, with a further 5% decline this year alone, according to Turković. Prices have slipped below EUR 100,000 per MWh.
Turković: Regarding CAPEX and technology, we’re ready
The latest trend is the integration of batteries with solar power plants. While transmission system operators in the region still don’t allow it, in some countries a grid connection approved for solar can also be used for batteries. “Regarding CAPEX and technology, we’re ready,” Turković underlined.
Aleš Prešern, Vice President and Head of Southeast Europe in Siemens Energy, is particularly impressed with the speed of change.
“We who are working in the energy sector are used to very slow changes. Energy was a conservative industry. In 2004, 1 GW of solar was built, but now data shows that it is how much is installed in one day. Batteries cost EUR 1 million per MWh not that long ago, and now they are ten times cheaper,” he noted.
Prešern: Transmission networks are the bottleneck of the transition
They are indeed dramatic changes, for which the existing power system wasn’t prepared. It is clear why Siemens Energy, as a technology company, considers transmission networks to be the bottleneck in the transition, Prešern said.
To illustrate the slowness of grid investments, he pointed to Austria, as one of the examples, where it took 10 years to build one important segment of the 400 kV network.
Both Turković and Prešern agree that nowadays the keyword is flexibility.
She explained there are operating battery management systems at low voltage levels that incorporate artificial intelligence and use market signals for activation when prices are low.
Prešern added that the required stability through balancing could be provided by gas power plants. Siemens Energy has never seen such high demand for gas turbines like today, he asserted.
Beynio: Don’t forget the non-banking institutions when looking in new financing
“If you ask about availability of financing, yes, it’s there,” Christian Beynio, Head of Advisory at Kommunalkredit Austria AG, confirmed. In his view, prices or, rather, the drop in prices of equipment, is the biggest innovation. Earlier, he said, it was a completely different game, heavily subsidized, while nowadays no subsidies are required per se.
The trend that Kommunalkredit Austria AG identified is the pooling of smaller assets, and a shift from financing projects toward financing developers and companies as corporates. It is yet to come to the region, he added.
Battery projects won’t go so smoothly
Maja Turković expressed the belief that installing batteries won’t go as smoothly as solar. The main reason is the difficulty of securing a stable cash flow for batteries, unlike for production facilities. Cash flow enables financing, so batteries will likely need to be financed with internal funds, she underlined.
Turković noted that batteries are best monetized by providing system services and arbitrage, but pointed out they can also participate in capacity mechanisms, a scheme that could involve power purchase agreements (PPAs).
She said the development of the regulatory framework should be faster, to facilitate investments in batteries. Investors are ready to commit their funds to battery installation, and everyone in the market agrees that batteries are essential, Turković stressed.
Prešern: People and not technology are a guarantee that networks will exist and function properly
Amid the widespread discussions about technology and regulations, Aleš Prešern highlighted another issue. Energy, in his opinion, has always been an exciting sector, but the message hasn’t been getting through to young people in recent years. It was the case not only in the region but also in Europe, and beyond, leading to a shortage of skilled personnel.
However, he expressed the belief that things are changing and enthusiasm is returning. Prešern even suggested it could be a major advantage for the region, well known for its high-quality engineers.
Siemens Energy strives to employ as many good engineers as possible because, ultimately, people and not technology are a guarantee that networks will exist and function properly, he stressed.
The solution is also in using new technologies to better utilize existing grids
The combination of rapid changes in the energy sector and slow investments in the grids threatens to put the transition to a standstill.
Better utilization of existing infrastructure could be the solution. Siemens Energy fits well there, as several years ago it established a division called Digital Grid. According to Prešern, the idea was to be quicker in data utilization, something that other sectors like automotive have long advanced, while energy has lagged.
The company recently acquired a Slovenian-Austrian firm that produces sensors installed directly on power lines, a technology called dynamic line rating. The devices provide real-time data about the conditions in power lines, potentially enabling their use beyond original design limits.
“With this technology, we believe we can increase the capacity of existing networks by an average of 30%,” Prešern revealed.
New technologies have changed bankers’ jobs as well
New technologies have changed bankers’ jobs as well, Christian Beynio admitted. He recalled that it was easy to finance wind farms in Serbia because they had feed-in tariffs from the government. The only risk element was the wind blowing or not blowing, Beynio said.
Nowadays there are merchant power producers that combine their facilities with batteries and use algorithms in electricity trading, he added. It means bankers need to sit with market consultants to identify all outcomes, he stressed.
“You won’t find singular cash flow streams. It’s going to be multi-dimensional and people simply need to adjust. It’s going to be more short term also on the lending side. It’s rather going to be corporate lending to people and companies who know what they are doing and can credibly demonstrate that with a track record. That is the digitalization impact we see”, Beynio said.
