Radovan Grbović, partner and attorney with over 20 years of experience, addressed the participants, emphasizing the importance of mutual support and a stronger role for women in sustainable energy and the green transition.

Mentorship is about sharing life experience

The program’s outcomes were presented by Nataša Vukmirović, professional mentorship coach from the International Institute for Coaching and Mentoring, who highlighted that the program’s goals had been fully achieved. She noted that strong relationships of trust had been built and that most participants had expressed a desire to continue engaging in similar initiatives.

“Through evaluation and facilitation of joint sessions, I had the opportunity to witness meaningful knowledge exchange and feel the power of support, trust, and shared learning. The program demonstrated that developmental mentoring is a valuable approach in the sustainable energy and green economy sectors and can significantly impact participants’ career development,” said Vukmirović.

According to her, the program goes beyond education—it is based on values that empower individuals and protect the common good. This is echoed in the positive experiences of participants.

Marija Rošulj emphasized that her positive experience with Ivona Milić inspired her to become a mentor herself. “Mentorship is not just about work, but about a person’s character and sharing life experience, not just professional experience.”

The pair plans to continue working together and develop a joint project beyond the formal program.

Turning abandoned coal mines into PV plants could boost global solar capacity by 15%

Building photovoltaic plants on abandoned open-pit coal mines could add nearly 300 GW of new solar worldwide, equivalent to 15% of the current global capacity, according to a survey by Global Energy Monitor (GEM). Greece and three Western Balkan countries are among the global leaders in projects to build solar at abandoned coal mines.

It shows that over 300 open-pit coal mines recently out of commission could house around 103 GW of photovoltaic capacity, while upcoming closures of 127 large operations could host an additional 185 GW of solar. Nearly all abandoned coal mines and upcoming closures covered by the survey are in close proximity to existing grid infrastructure, including substations and transmission lines.

The 15% increase in solar capacity could cover the electricity needs of Germany

GEM estimates that this 15% increase in the global solar capacity would be roughly enough to meet the annual electricity consumption of a country like Germany. The report also notes that coal mine to solar conversion is a practice that aligns land reclamation with clean energy goals and local job creation.

GEM recalls that in 2024, total solar capacity additions in the world reached a record 599 GW, with more than 2 TW of utility-scale projects currently under development.

GEM: China is the global leader in coal-to-solar transition

China is the global leader in coal-to-solar conversion, with 90 projects already operational, totaling 14 GW, and 46 more in the pipeline, with a combined capacity of 9 GW, according to GEM’s survey. Australia has 2.7 GW of announced projects, followed by the United States, with about 1.3 GW of announced projects and as much in the pre-construction phase.

In Europe, Greece leads the way, with 1.44 GW of announced projects and 550 MW in the pre-construction phase, while Germany has a total of 868 MW, of which 20% are already operating and 75% are in the pre-construction phase, according to GEM’s data.

In the Western Balkans, North Macedonia has 100 MW of projects under construction and another 100 MW announced, followed by Bosnia and Herzegovina, with 115 MW in the pre-construction phase, and Serbia, with 97 MW of announced projects.

GEM’s survey covered only open-pit coal mines decommissioned in the last five years and those whose closure is expected by the end of 2030.

However, according to announcements from developers and grid operators, several large-scale PV projects on coal land have already been completed in the region tracked by Balkan Green Energy News.

In Greece, the capacity in operation is nearing 1 GW. In North Macedonia, a part of the REK Oslomej coal power complex is now home to three solar power plants, with a total capacity of 140 MW, while in Serbia, the 9.75 MW Petka PV plant is about to go online.

Ireland ends coal use – Spain, Italy, Greece set to follow

The Moneypoint power plant stopped burning coal, marking the end of Ireland’s coal era. The last such facilities in several other countries in the European Union are operating only barely or occasionally.

Ireland has ended coal power generation. It is the eleventh coal-free country in the European Union and the 15th in Europe overall. Notably, nine countries in total never hosted coal power plants, according to the Beyond Fossil Fuels database.

Slovakia and Spain officially intend to exit coal this year, followed by Greece (2026), France and Hungary (2027) and Denmark (2028). However, the dates could be pushed forward and there is a possibility that more countries will join the group in the meantime. Several of their remaining facilities are active just sporadically – in islands or to cover winter peaks or only until the district heating systems that they supply switch to cleaner sources.

For instance, the share of coal power in Finland is minuscule.

Coal power is already uncompetitive most of the time. Moreover, when such facilities are idle, their costs rise further because of salaries and the complex logistics.

Moneypoint plant switches to backup with heavy fuel oil

The Moneypoint plant in Ireland ceased burning coal last week earlier than planned. Its operator ESB is turning the site into a renewable energy hub.

At the turn of the millennium, wind supplied just 1% of the country’s electricity. Today, it generates more than a third.

“The government’s priority now must be building a power system fit for a renewable future; one with the storage, flexibility, and grid infrastructure needed to run fully on clean, domestic renewable electricity,” said Alexandru Mustață, campaigner on coal and gas at Beyond Fossil Fuels.

Moneypoint will serve a limited backup role until 2029, burning heavy fuel oil under emergency instruction from transmission system operator EirGrid.

Subsea interconnections to enable coal phaseout completion in Spain, Italy

Spain and Italy are set to follow suit, excluding the Balearic Islands and Sardinia, respectively.

Brindisi Sud (2 GW) and Torrevaldaliga Nord (2 GW) are expected to cease regular operations in mid-2025 and are set to be placed into a strategic reserve, pending full decommissioning. Italy’s remaining coal plants, Sulcis (590 MW) and Fiume Santo (640 MW) in Sardinia, are expected to remain online until a second undersea grid cable to the mainland is completed.

Aboño (916 MW) in Spain is being converted from coal to fossil gas. Soto de Ribera (350 MW) and Los Barrios (589 MW), are barely operating. The Alcúdia plant in the island of Mallorca has two coal units of 130 MW each. Its closure depends on the construction of the archipelago’s second interconnection with the mainland.

Slovakia’s coal phaseout was extended for a short while as a smaller unit kept using what it had left in stock

Slovakian energy company Slovenské elektrárne ended production at its combined heat and power (CHP) plant Vojany (220 MW) in March of last year, which was supposed to mark the country’s coal exit. However, the Teko facility of 121 MW continued to operate with its remaining stockpiles to cover the winter season.

The Cordemais coal plant (1.2 GW) in France is designated for closure in 2027. Émile-Huchet (600 MW), the other remaining facility in the country, should be converted to gas by then.

Turkey, Germany, Poland, Slovenia, the Czech Republic, Serbia, Montenegro, Bosnia and Herzegovina and Kosovo* have the largest shares of coal in power production in the European Union and Southeastern Europe.

* This designation is without prejudice to positions onstatus and is in line with UNSCR 1244/99 and the ICJ Opinion on the Kosovo declaration of independence.

OMV Petrom enters Bulgarian solar power market as partner in one of biggest projects

As part of its decarbonization efforts, Romanian hydrocarbons producer OMV Petrom is strengthening its presence in neighboring Bulgaria. It agreed to buy 50% of the Gabare solar power project, of 400 MW, from its developer Enery Element.

The solar power investment frenzy in most of Southeastern Europe is continuing despite rising curtailments and the frequent occurrence of negative power prices. Major developers and operators are counting on battery storage to gradually close the still widening gap between intraday peak production and consumption in spring and autumn.

Romanian oil and gas company OMV Petrom – a subsidiary of OMV – is acquiring a 50% stake in Bulgarian firm Dunav Solar Plant. It is developing the 400 MW Gabare photovoltaic project in Byala Slatina near Sofia.

Until now, the sole owner was Enery Element, a joint venture between Austrian renewable energy company Enery Development and its Bulgarian partner Element Power Group. The two sides didn’t disclose the amount. They expect to close the transaction later this year, after fulfilling certain conditions.

Partners to invest EUR 200 million in total by production launch in 2027

The solar park is expected to enter commercial operation in 2027. By then, OMV Petrom and Enery plan to invest EUR 200 million, including from external financing. They are targeting their final investment decision before the end of 2025.

Solar trackers will maximize output, which will be equivalent to the consumption of 150,000 domestic households, the Romanian company pointed out. A battery energy storage system (BESS) of up to 600 MWh in capacity is an option for future consideration, OMV Petrom added.

Neel: Natural gas and renewables complement each other

“By investing in one of the largest photovoltaic projects in Bulgaria, we are strengthening our presence on this neighbouring market and are supporting the region’s energy transition. We believe that natural gas and renewables complement each other and play a key role in reducing emissions while ensuring energy stability,” said member of the Executive Board of OMV Petrom Franck Neel, responsible for the Gas and Power division.

He added that the company would also offtake 50% of the generated electricity, through a power purchase agreement (PPA), without revealing further details.

Enery currently generates almost 700 GWh of clean electricity per year from 490 MW in installed capacity. It has 8 GW in the project pipeline in 11 countries.

Permits for PV park secured

The construction permits and the grid connection have already been secured, according to the update. At 400 MW in peak capacity, Apriltsi is the largest solar power plant in the Balkans and Eastern Europe, excluding Turkey.

However, a PV system of 550 MW in Greece is about to be completed.

OMV Petrom is the largest integrated energy producer in Southeastern Europe, with an annual group hydrocarbon production of 40 million barrels of oil equivalent in 2024. In addition, it is expanding in the segments of wind power and photovoltaics, energy storage, alternative fuels including green hydrogen, and chargers for electric vehicles.

OMV earlier expressed interest in renewables in Serbia and Hungary as well

The group has a refining capacity of 4.5 million tons. It operates an 860 MW high-efficiency gas-fired power plant. The group is present in Romania and neighbouring countries through 780 filling stations under the brands OMV and Petrom, of which 93 in Bulgaria.

At the end of last year, Austrian energy giant OMV had a 51.2% stake in OMV Petrom. The Romanian Ministry of Energy controlled 20.7% and pension funds in the country participated with 23.7% in total.

In Bulgaria, OMV Petrom started supplying natural gas to business customers last year. Following the discovery of gas resources in Romania’s Neptun Deep block in the Black Sea, it is now exploring the gas potential in Bulgaria’s Han Asparuh block. In April, the company said it approved an investment budget of EUR 1.6 billion for 2025, or over 20% more than in 2024.

Pparent company OMV, headquartered in Vienna, expressed interest last summer in the wind and solar power potential of Romania, Serbia, Bulgaria and Hungary.

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.

Coal power plant Maritsa East 3 plans to build solar plant, 200 MW battery system

Coal-fired power plant ContourGlobal Maritsa East 3, which operates only sporadically to ensure the stability of supply for Bulgaria’s power system, plans to repurpose the grid infrastructure of its units 1 and 2 for solar and battery storage capacities. Units 3 and 4 will remain on standby to generate electricity during peak demand periods in the summer and winter months, but the plant will need state support to cover maintenance and workforce costs.

Maritsa East 3 (Maritsa iztok 3), majority owned by the US-based ContourGlobal, plans to use the existing grid infrastructure, including transformers and switchgear, to speed up the green energy project within the complex, according to Vassil Shtonov, Executive Director of ContourGlobal Bulgaria.

The central element is a 200 MW standalone battery energy storage system (BESS), the largest of its kind in Bulgaria, which would improve the flexibility and stability of the national power system, Shtonov explained in an interview with Capital.bg.

The project involves a 200 MW standalone battery system and a solar power plant

The planned battery system at Maritsa East 3 was among 82 projects selected to receive a total of EUR 587 million in subsidies from Bulgaria’s Ministry of Energy in April this year.

“In parallel, we are considering the development of an additional hybrid solar park with a battery at the same site,” he said. This will allow for faster deployment of new clean energy capacity, while preserving all options for future use of the coal-fired plant and its original infrastructure, Shtonov added.

ContourGlobal plans to build 400MW to 500 MW of renewable energy capacity combined with batteries

ContourGlobal plans to invest hundreds of millions of euros to develop 400 MW to 500 MW of renewable energy capacity combined with storage systems, he said, adding that nearly half of this target is under construction or final approval. The company’s goal is to phase out coal by 2027 and achieve carbon neutrality by 2040, he stressed, recalling that Bulgaria’s targeted coal phaseout date is 2038.

Keeping coal plants on standby requires state support

Bulgaria’s state-owned National Electricity Co. (NEK) holds a minority stake in Maritsa East 3. After the plant’s 15-year power purchase contract with NEK expired in February 2024, it has only been able to operate on the free market for a few months a year. This year, units 3 and 4 were online from January to the end of March to maintain energy security.

Shtonov: Key coal-fired power plants should get a fixed amount from the state

However, to be on standby for system security, the plant needs to keep workers on the payroll even when it is not operating. For this reason, strategically important coal-fired power plants should receive a fixed amount from the state to cover ongoing personnel and maintenance costs, and then be switched on when necessary to protect consumers from sharp increases in electricity prices, as happened last year in July and November, according to Shtonov.
