Econergy to assume 100% ownership of Romania’s biggest solar park, add batteries

Econergy agreed to buy out Nofar’s 50% stake in the 155 MW Rătești photovoltaic plant, the largest in Romania. The next step is to add a 120 MW battery energy storage system.

Econergy Renewable Energy said its subsidiary Econergy International, in which it holds 75.2%, has signed an agreement with Nofar Energy to acquire the partner company’s entire 50% stake in the Rătești solar power plant. The facility northwest of Bucharest, in Argeș county, is the largest in Romania. It has 155 MW in peak capacity.

Following the transaction, Econergy will hold 100% ownership and assume control of the shareholder loan previously provided by Nofar, of EUR 14.9 million, according to the update. The total consideration for the transaction is €45.6 million, payable in three instalments through June 2026.

Both companies are based in Israel. Econergy expects a capital gain of EUR 13 million from the deal. Like with some of its other investments in Romania, it plans to add a 120 MW battery energy storage system (BESS). The operator values the investment at EUR 32 million.

The battery storage facility is expected to enter commercial operation in the second quarter of next year, Econergy revealed. It would generate an additional EUR 15 million in annual revenue and EUR 12 million in earnings before interest, taxes, depreciation and amortization – EBITDA, the announcement reads.

Econergy said its portfolio of solar, wind and storage projects in Romania amounts to 3.5 GW. It includes 473 MW in operation or facilities that are ready to connect, 763 MW under construction and 395 MW scheduled to begin construction by the end of the year. Total project pipeline exceeds 14 GW.

City of Pirot in Serbia plans solar power plant on remediated unsanitary landfill

The City of Pirot plans to build a solar power plant on the site of a former unsanitary landfill when it is remediated. The move would strengthen its leadership position in Serbia regarding the use of renewable energy and environmental protection.

In 2013, Pirot opened a regional sanitary landfill, which cost EUR 11 million. It enabled the local authority to shut down an unsanitary landfill on the right bank of the Nišava river. However, the land still hasn’t been remediated and reclaimed.

Now the Ministry of Environmental Protection of Serbia has approved EUR 2 million for the works, Serbia’s public broadcaster RTS reported. With the completion of remediation, the possibility opens up for the six hectares of land in the country’s southeast to be repurposed.

Solar panels would be installed on three hectares

Mayor of Pirot Vladan Vasić said that the documentation for the remediation of the landfill is complete. The city intends to add EUR 500,000 to the EUR 2 million received from the government and complete the first phase. He plans for the second phase to be approved next year, to solve the decades-long issue in an environmentally acceptable way.

Vasić revealed one and a half to two hectares would be allocated for businesses, adding that the purpose of the remaining land is still under consideration.

A photovoltaic plant would be the most cost-effective solution

One idea is to install a 3 MW solar power plant that would supply electricity to the city authority, he pointed out.

Other ideas are a football stadium, a golf course, afforestation, and a park. The photovoltaic plant would be the most cost-effective solution, Vasić added.

Of note, there is a solar power plant on the roof of the building of public waste utility Regional Landfill Pirot. The 150 kW facility began operating in August last year. The city officials claim it is the largest PV plant in Pirot county.

The first cooperative solar power plants in Serbia are located on the Stara Planina mountain

Pirot is also developing a regional waste management center. In 2022, the city signed a contract for the construction of the second landfill body, a composting plant, and a biogas facility.

The additional segment would extend the operation of the sanitary landfill by 20 years, while the biogas collection system would enable the collection of methane from the landfill.

A system for treating construction waste to enable material recycling is planned as well.

As for solar energy, not far from the city, the Stara Planina mountain is the home of the first cooperative solar power plants in Serbia. The local authority participated in the project. They were put into operation last year.

In mid-2023, PV projects were under development for over 125 MW in total capacity on the city’s territory. Of note, this year Pirot became the 13th local authority to join the Clean Air Regions Initiative, initiated by the Energy Community Secretariat.

Romanian town signs partnership for 200 MW solar park with BESS

A firm recently established by Turkish and Romanian investors has launched a public-private partnership with the local authority in Târgu Lăpuș in northern Transylvania. They are planning a hybrid power plant worth EUR 100 million.

A public-private partnership in the making in northern Romania is aimed at building a 200 MW photovoltaic plant, the largest in Transylvania, with a battery energy storage system, 2Mnews reported. Global Energy Asset, a firm founded by Turkish and Romanian investors less than half a year ago, has signed a deal with the municipal authority in Târgu Lăpuș.

The investors value the project at EUR 100 million. They intend to install the facility on 200 hectares on the territory of the town, also known as Magyarlápos. Târgu Lăpuș is in Maramureș County.

The seat of Global Energy Asset, formerly known as Global Finance Asset, is Tunari in Ilfov county near Bucharest. In addition to financial benefits and covering the costs of electricity for street lighting, its representatives offered the local authority scholarships for children and sponsorship of events and institutions, the article reveals.

The project firm’s largest shareholder reportedly has ties with Feridun Geçgel of Astor Enerji

Muhammed Ishak Çiftçi, who has Romanian citizenship, controls 48% of the project firm. According to the news outlet, he is associated with Turkish billionaire Feridun Geçgel, Chairman of the Board of Astor Enerji.

It is the largest manufacturer of transformers in Turkey. Astor Enerji entered the Romanian photovoltaic market this year by acquiring four projects for 279 MW in total.

In August, Swiss energy storage provider Energy Vault agreed to supply up to 2 GWh of battery capacity for the Turkish company’s future solar power plants in Romania. Astor Enerji is listed on the Istanbul Stock Exchange (Borsa Istanbul).

Head of Global Energy Asset, lawyer Cătălin Iulian Marin, holds 25%, and there are four more co-owners.

Approving the proposal for the public-private partnership, Târgu Lăpuș town hall cited the need for business ventures amid economic difficulties. Namely, furniture manufacturer Taparo, which supplied IKEA and was the biggest business in the area, has become insolvent.

Sunterra RE equips its PV plants in Bulgaria with batteries totaling 156 MW

Bulgarian solar power plant operator Sunterra RE added co-located energy storage to its operational portfolio. The company’s three photovoltaic systems, with 524 MW in combined peak capacity, now also have batteries of 156 MW and 312 MWh in total.

With the ongoing solar boom in Bulgaria, investors have lately also been rushing to set up co-located and standalone battery energy storage systems (BESS). Bridging the gap between the peaks of daily photovoltaic production and power consumption is one of the key factors for the energy transition – stabilizing prices and the electricity system’s stability. Sunterra RE – Santera RE in Bulgarian – stands out with a large new operational solar and battery portfolio.

In its latest updates, the company revealed that it has put three BESS facilities into operation. They are co-located with its photovoltaic plants of 524 MW in total peak capacity.

There are 77 lithium-iron-phosphate (LFP) battery units now online. They have an overall capability of 156 MW and a duration of two hours. It translates to 312 MWh in storage capacity.

The investments received support through the National Recovery and Resilience Plan (NRRP), funded from the European Union’s Recovery and Resilience Facility – RRF. Sunterra RE said it completed them in less than a year.

Galabovo BESS accounts for half of battery operating power

The Kaloyan solar power plant of 208 MW, also known as Dalgo Pole, was the biggest in Bulgaria for a short while. It is backed with a 47 MW / 94 MWh facility, comprising 23 battery units.

The BESS investment at the site just north of Plovdiv was worth BGN 31.7 million (EUR 16.2 million).

The three subsidized battery projects were completed in less than a year

Accompanying the Galabovo solar power plant (201 MW) is a BESS with 75 MW in operating power. Sunterra RE said it consists of 37 battery containers. The Galabovo municipality is east of Plovdiv, Bulgaria’s second-largest city.

The remaining seventeen units, of 34 MW, make up the battery energy storage system at the Karlovo solar power plant. The PV facility in the eponymous municipality north of Kaloyanovo, has 115 MW.

The company’s fourth photovoltaic plant, in Pleven in the north, has only 9.6 MW.

Sunterra RE to expand its three new energy storage facilities by over 1 GWh altogether

Sunterra RE recently entered into a strategic partnership with Sungrow to expand the three BESS by more than 1 GWh in total. The deal is for the China-based partner’s MV-Power Titan 2.0 LFP units and accompanying equipment and software.

The city of Lovech, northeast of Sofia, hosts the strongest BESS in the Balkans – of 124.1 MW and 496.4 MWh. It is a standalone battery facility, part of a closed power distribution system.

Renalfa IPP and Eurowind Energy are installing a 315 MW / 760 MWh BESS at their Tenevo PV plant. They plan to turn it into the largest and most complex hybrid power plant in Bulgaria.

Kyiv, the heart of Ukraine, is a city renowned for its golden domes, cultural depth, and enduring spirit. In recent years, especially since the full-scale invasion of Ukraine in 2022, the people of Kyiv have faced extraordinary challenges. But amid the destruction and uncertainty, a new kind of rebuilding has taken root – one that is greener, smarter, and focused on long-term sustainability.

When the war disrupted supply chains, energy infrastructure, and food systems, communities across Kyiv were forced to adapt quickly. What began as survival soon evolved into innovation. As energy security became a national priority, citizens and officials in Ukraine’s capital started reimagining what a more self-reliant and sustainable city could look like.

One of the most visible changes has been the rise of solar energy. While Ukraine had been developing renewables before the war as well, the conflict accelerated the adoption of decentralized energy sources.

In many neighborhoods, especially those affected by blackouts and grid instability, residents pooled resources to install rooftop solar panels, solar-powered water heaters, and even small-scale battery storage systems. Tenants’ associations in apartment buildings began using crowdfunding platforms to raise money for green energy upgrades. My neighbor, for example, spearheaded a project in our building to install solar panels that now help power our elevator and joint lighting systems.

Solar energy became lifeline for schools, hospitals, critical infrastructure

Schools and hospitals also embraced solar as a lifeline. Through international aid and local initiatives, dozens of Kyiv’s critical infrastructure facilities have been outfitted with renewable energy systems.

This isn’t just about environmentalism – it’s about resilience. When the power goes out during missile attacks or rolling blackouts, these systems keep vital services running. The city’s shift to green energy has become a form of defense as much as it is a commitment to sustainability.

Waste management has also undergone a transformation. Before 2022, recycling in Kyiv was limited and often inconsistent. But since the war began, grassroots recycling programs have surged. Volunteer-led sorting centers appeared in districts like Obolon, Podil, and Solomianskyi, where residents bring plastics, paper, electronics, and batteries.

These centers often operate out of garages, schoolyards, or community centers – and they’re staffed by locals determined to reduce waste and pollution. The Zero Waste Alliance Ukraine, a nonprofit that started as a small awareness campaign, has grown into a national network promoting sustainable consumption and waste reduction in cities like Kyiv.

Modernizing Kyiv’s subway system is priority

Public transportation is another area where the city has made strides. Although metro stations are damaged and they doubled as bomb shelters during attacks, Kyiv’s subway system remains one of the greenest forms of transport in the region. The city government, recognizing its importance, has prioritized its modernization.

The number of cyclists is rising, and so is the length of bike lines

Electric buses are being introduced, and there are pilot projects for low-emission zones in the city center.

The number of bicycle commuters has also increased significantly since fuel prices soared and road conditions became more unpredictable. I started biking to work last year, and I’ve noticed more bike lanes being marked, as well as more people making the same choice – not only for convenience but for the environment.

Local communities farming strawberries between buildings

Food systems are shifting, too. With imports disrupted and many large-scale farms in occupied or war-damaged areas, Kyiv residents began to grow food in unexpected places. Urban gardening took off in parks, on balconies, and even in underground shelters.

In our district, we turned a neglected courtyard into a communal garden with tomatoes, herbs, and strawberries. It’s not a large-scale solution, but it brings people together, reduces dependence on long supply chains, and fosters a deeper connection to the land.

Green startups popping up throughout Ukraine’s capital city

Crucially, these changes are being supported by a growing culture of green entrepreneurship.

Startups focused on eco-construction, sustainable packaging, and electric mobility are popping up throughout the city. One standout example is a Kyiv-based company that makes biodegradable packaging from hemp – a plant widely grown in Ukraine.

Another startup, EcoFactor, retrofits older buildings to improve their energy efficiency, employing many internally displaced people in the process. These green businesses don’t just support the environment; they offer livelihoods and hope amid uncertainty.

Youth and students are looking toward a sustainable post-war future

Perhaps most inspiring is the role of young people in this transition. Ukrainian youth have always been politically and socially active, but the war has heightened their sense of responsibility.

Environmental clubs in Kyiv universities are organizing climate literacy workshops, cleanup events, and public advocacy campaigns – even during air raid alerts. I recently attended a student-led event called Green Rebuild, where architecture and engineering students presented ideas for post-war reconstruction using sustainable materials and passive design principles.

It struck me that the generation growing up during war is also the one leading us toward a cleaner, more conscious future.

Even amid destruction, there can be creation

Our shift toward a green local economy isn’t linear or perfect. There are still challenges with funding, access to technology, and bureaucratic delays. And yet, what’s happening here is remarkable: a city under siege is laying the foundations for a sustainable future. We are proving that even amid destruction, there can be creation – that rebuilding a nation can also mean rethinking how we live, produce, and share.

In Kyiv today, sustainability is not just a political goal or a global trend – it’s a grassroots reality. It’s neighbors coming together to plant gardens, fix solar panels, sort recyclables, and imagine better ways of living. It’s resilience not only in the face of war, but in the face of climate change, inequality, and old ways of doing things.

The capital city’s story is still unfolding. But as we rebuild, we are building green – not because it’s fashionable, but because it’s essential. And in doing so, we’re showing the world that even in the darkest moments, there is light – and sometimes, that light comes from solar panels on a Kyiv rooftop.

City of Osijek has highest waste separation rate in Croatia

Osijek has reached a 57.92% waste separation rate in 2024, the highest score among the four largest cities in the country.

Osijek, with a share of 57.92% of separately collected waste, is again the best among large cities in Croatia, according to Mayor Ivan Radić. Because of the achievement, he visited the employees of the city’s waste utility Unikom in the early morning hours.

He stressed that the success is the result of responsible citizens who separate waste, the dedicated work of Unikom employees, and ongoing investments in infrastructure.

Osijek has four recycling yards, including a mobile one. They are able to separate 52 types of waste. There is also a composting facility. As the mayor pointed out, the local authority invests in consumer education, from kindergartens to its Eco City Waste Fest, because it aims to maintain and improve the achieved results.

Osijek is the only major Croatian city that doesn’t pay penalties for not achieving waste separation targets

Radić underlined that Osijek is the only large Croatian city that, thanks to waste separation above 50%, doesn’t pay penalties.

Municipal authorities in Croatia pay fines per ton of landfilled waste that was supposed to be separated and properly processed in line with waste management rules. The fine for 2025 was set at EUR 30 per ton. The obligatory separation rate for 2025 is 50%.

Unikom CEO Igor Pandžić highlighted that in 2024, a total of 36,000 tons of municipal waste were collected, of which nearly 21,000 tons were recyclable waste. The largest portion was biodegradable waste, thanks to the composting unit, into which the city continues to invest.

Osijek has maintained a waste separation rate above 57% for two consecutive years

Paper, plastic, glass, and metal accounted for over 9,000 tons, Pandžić said, and recalled that Osijek achieved a waste separation rate above 57% for two consecutive years.

He said more projects are underway, including the expansion of the composting facility and the establishment of a center for recycling bulky waste, which would further reduce the quantities ending up at the Lončarica Velika landfill.

In Pandžić’s words, they are important steps in terms of the circular economy. “What our fellow citizens separate, we process into a new product like compost, which then goes back into gardens and yards,” he explained.

At the meeting with the workers, the mayor and the CEO announced a 10% salary bonus as a reward for their work.
