Uncertain future of Greece-Cyprus Great Sea Interconnector project

Greece and Cyprus find themselves at odds when it comes to Great Sea Interconnector (GSI), their big project for a subsea electricity cable. A new investigation by the European Public Prosecutor’s Office (EPPO) further complicates things.

Great Sea Interconnector is an envisaged 1,208-kilometer power line that would connect Crete, Cyprus and Israel. Planned for 1,000 MW in capacity and doubled later, the link would provide energy security and lower energy costs for Cypriot consumers, who currently pay the highest wholesale prices in Europe. Cyprus has also been plagued by very high curtailments and rolling blackouts, meaning that a solution is needed urgently.

The EUR 1.9 billion project benefits from a EUR 657 million funding from the Connecting Europe Facility (CEF), for the Greece-Cyprus section. It is also included in the Projects of Common Interest (PCI) list.

Currently, GSI is at the stage of bathymetric surveys in the offshore region between Greece and Cyprus. Italian ships were hired, but they were stopped last year by Turkish naval forces near the island of Kasos, east of Crete. This year, the Greek government appeared ready to reinitiate the surveys, this time with military escort, but in recent days, the government in Nicosia raised new concerns.

Cyprus raises cost issues

Statements by the two governments revealed diverging views about GSI. Cyprus has raised the issue of economic viability, with Minister of Finance Makis Keravnos maintaining a hard line and saying that it is not evident whether the interconnection would benefit his country.

“No one knows how much it will cost consumers and when the project will be completed,” said Keravnos.

Greece responded by reminding the decision makers in Nicosia that an agreement was signed last year, specifying that Cyprus needs to pay EUR 25 million annually to the project promoter, the Greek Independent Power Transmission Operator (IPTO or ADMIE). The first payment is expected this year, if the project is to continue.

IPTO has said that without the remaining decrees from Cyprus Energy Regulatory Authority (CERA or RAEK), it would stop paying Nexans, the French company in charge of building the cable. At that point, the interconnector project freezes.

Essentially, Greece wants Cyprus to pay before it moves ahead with new surveys around Kasos, which could trigger a military showdown with Turkey. On the other hand, the government in Nicosia wants Greece to complete the surveys before providing the money, thus removing any geopolitical risk.

Mitsotakis: Cyprus must show it wants the project

“Cyprus is the primary beneficiary of this project, therefore it must show its commitment,” said Greek Prime Minister Kyriakos Mitsotakis.

Things have been further complicated by EPPO’s new investigation. According to leaks in the Cypriot press, the administration in Brussels is looking into potential mismanagement when EuroAsia Interconnector was the project promoter, before IPTO took over.

Geopolitics at the epicenter

However, the elephant in the room is the geopolitical issue. Greece and Cyprus have delimited their exclusive economic zones (EEZs) in the waters between them, in line with international law. However, they haven’t signed a bilateral demarcation agreement.

Turkey, on the other hand, laid a claim over the marine region. It is one of the few countries that have not signed the United Nations Convention on the Law of the Sea (UNCLOS). In 2022 it signed an EEZ agreement with Libya to solidify its claims, which Greece, Cyprus and the European Union have called illegal.

Romania preparing to include biomethane in gas grid

Romania has drafted a directive that would regulate the production, transportation and distribution of biomethane and its inclusion into the gas network. The change is aimed at limiting the increase in the prices of gas for household heating, expected from the upcoming introduction of the ETS 2 carbon allowance scheme in the European Union. Delaying the shift would also affect the costs of industrial production and for other non-household consumers of gas.

Biomethane produced from sustainable sources is carbon neutral under the EU Emissions Trading System (EU ETS), making it appropriate for buildings and transportation, the Romanian Ministry of Energy said in a new draft emergency ordinance. With the executive order, it intends to pave the way for utilizing the renewable fuel in the natural gas network, Profit.ro reported.

The document is set to amend several acts and regulate the production, transportation and distribution of biomethane. It would counter, to an extent, the increase in gas prices for households, which is expected from the expansion of the EU’s carbon pricing scheme to buildings and transportation, the ministry explained. Namely, ETS 2 is scheduled to be introduced in 2027.

Biomethane is usually obtained by processing biogas to get methane of the same purity as in fossil gas

Any delay in allowing biomethane in the existing grid draws a risk of increasing the costs of natural gas consumption, both for non-household and household customers, the accompanying note reads.

Biomethane is usually obtained by processing biogas to get methane of the same purity as in fossil gas. The gaseous biofuel can also be produced from clean hydrogen and carbon dioxide. The EU allows incentives for biomethane facilities. Some countries in Southeastern Europe, like Greece, are developing the legal framework for embracing the technology within their energy transition.

Share in gas network planned to reach 10% by 2050

Romania is planning a 5% share of biomethane in its natural gas network in 2030 and to double it by mid-century. The sectors of waste management and agriculture can produce an estimated 501,000 tons of oil equivalent in 2050.

The EU is imposing strict requirements on the removal of biodegradable organic matter from wastewater and the reduction of food waste, the ministry noted. Together with agricultural and organic municipal waste, they are the main raw materials for the production of biogas.

According to the proposal, publicly announced business plans can secure a share of renewable gases in the grid up to 1.5%. However, without an urgent legislative intervention, the investments can’t materialize, the Ministry of Energy warned. The draft directive would update the definitions of guarantees of origin, biogas, biomethane, natural gas, renewable gases and biomethane producers.

BSOG Energy, Engie Romania at forefront of upcoming biomethane investment wave

As for other developments in the segment, BSOG Energy (BSOGE), a subsidiary of Black Sea Oil and Gas, recently hired industrial services provider Bilfinger for a biomethane facility in Alba county in Transylvania.

Earlier, BSOGE said it would invest EUR 30 million in the construction of a biomethane plant. It has signed deals with milk producer DN Agrar Group for up to 15 MW in capacity, with the possibility of exceeding 20 MW in later stages.

In April, the firm partnered with Unigrains Trading in a project for a biomethane and organic fertilizer facility. They estimated the investment at EUR 65 million, for 57 MW of biomethane capacity and over 250,000 tons of organic fertilizers per year. Parent company BSOG is controlled by controlled by investment firm Carlyle.

Engie Romania launched plans a year ago with Heineken to build a biodigester for brewery waste

Last November, French-owned Engie Romania obtained the first license in the country for biogas and biomethane supply. Earlier it established a partnership with Heineken for decarbonization projects in three breweries in Romania, including heat pumps and one biodigestion system.

The firm is the largest supplier and distributor of natural gas in the country, as well as an electricity producer and supplier.

Eco bride Milica Lukić celebrates love with sustainable wedding

Weddings are often associated with celebration, luxury, and significant resource consumption. However, the example of Milica Lukić, a researcher and environmental activist, shows that a celebration of love can be just as festive and emotional while remaining sustainable — without wastefulness or harm to the environment.

For many people, a wedding is one of the most important days of their lives. Choosing a dress, a suit, a venue, food, decorations, and music are just some of the elements that require detailed planning and organization. However, bringing a large number of people together in one place, along with traditional customs, often comes with a darker side: high carbon emissions, food waste, and excessive resource use. Still, there is another way.

Milica Lukić, a researcher at the Faculty of Geography, University of Belgrade, and a member of the WISE Serbia network, has demonstrated that a wedding can be organised with sustainability and care for the planet in mind. In addition to her academic career, Milica is also known as a dedicated environmental activist and an advocate for a healthier environment.

“When we talk about adopting more eco-friendly practices in everyday life, most people start with reusable shopping bags, refillable water bottles, or separating packaging for recycling. The next step is rethinking. Rethinking whether we can do something differently, which might take a little more time and planning but ultimately brings numerous benefits — for us as individuals, for society, and for nature,” Milica emphasizes.

It was precisely this mindset that inspired Milica to make her special day sustainable while also supporting the local community.

“The thought ‘less is more’ guided me throughout the entire process. That’s why I want to inspire others with my story so that, in the future, we have more examples like this,” she says.

The dress can wait for the right moment.

Choosing the right dress, the centerpiece of the celebration and likely the most eye-catching detail, can be a challenging task. It’s common for people to spend several hundred euros on this special garment, but Milica opted for a second-hand dress instead.

“The dress is always the biggest challenge, but luckily, there’s @retro.to.the.rescue, where I’ve been buying second-hand clothes for years. I bought the dress earlier and waited for the right moment,” Milica explains.

Retro to the Rescue is a charity-driven initiative, with all proceeds from sales donated to animal welfare organizations.

Love without a golden wedding ring

A wedding outfit is often paired with carefully selected jewelry made of precious metals and gemstones. However, behind the sparkling pieces lies a darker side. The jewelry industry is linked to numerous ethical and environmental issues: child labor, human rights violations, conflict financing, pollution, and environmental destruction.

That’s why Milica decided to use what she already had. “I’m most proud that I managed to resist the pressure when it came to wedding rings because gold reminds me of exploitation, mining, pollution — everything we are fighting against. Love doesn’t need a golden ring,” says Lukić, sending her support to activists in Eastern Serbia who have long been battling the consequences of mining and the influence of mining companies.

Responsible choices in beauty products protect the environment

The eco-conscious approach to Milica’s wedding was also reflected in her choice of makeup. The cosmetics industry produces around 120 billion units of packaging every year, most of which is non-recyclable plastic. It also relies on animal-derived ingredients and toxic chemicals such as parabens and phthalates.

Sustainable makeup involves products that are not tested on animals, contain no animal-derived ingredients, use natural pigments, and come in recyclable packaging. There are even zero-waste makeup options, such as refillable lipsticks packaged in metal or glass containers.

Milica chose a minimalist, sustainable approach — using vegan mascara and lipstick — and had her hair styled at a small local salon, explaining that she enjoys supporting small businesses, especially those owned by women.

She also bought her bouquet at a local market from an elderly woman selling flowers. “The night before, I tried making my own bouquet from flowers I picked in the neighborhood, but by morning, it had wilted. Even water didn’t help. Still, it won’t go to waste — it’ll continue its life in compost,” Milica says.

Sustainability reflects respect for nature, people, and the community

Instead of hosting a big wedding celebration, Milica chose a small family lunch at a local restaurant, with a vegan and vegetarian menu.

Through her example, Milica has shown that love doesn’t have to be celebrated according to traditional norms. What matters most is making the day authentic and aligned with the values we live by. Her wedding is a reminder that sustainability isn’t about giving things up — it’s about celebrating in a way that reflects respect for nature, people, and the community.

Airport in Cluj-Napoca secures grant for battery-backed solar park

International Airport Avram Iancu Cluj will cover more than half of the costs for a 5 MW solar power plant, with a battery energy storage system of 12 MW, from European funds. It expects the facility to cover more than 60% of its electricity needs.

Civilian airports throughout Southeastern Europe are building dozens of solar parks and rooftop photovoltaic systems to increase their energy autonomy and achieve cost savings. Some of the capacity is backed up by battery energy storage systems (BESS). International Airport Avram Iancu Cluj in Romania is set to join the group with a project worth EUR 10.7 million including value-added tax.

The Ministry of Transport and Infrastructure declared it eligible for EUR 6 million grant from the European Union’s Modernisation Fund. The operator is controlled by the Cluj County Council.

Cluj International Airport to save EUR 1 million per year

International Airport Avram Iancu Cluj in Transylvania serves Cluj-Napoca, Romania’s second-largest city. With the green light for EU funding, it can proceed with the PV project of 5 MW with an energy storage unit of 12 MW in operating power. The airport expects the facility to cover more than 60% of its electricity consumption.

The airport in northwestern Romania serves Cluj-Napoca, the country’s second-largest city

The system would span eight hectares and include more than 7,500 solar panels. It is intended only for self-consumption. Cost savings amount to an estimated EUR 1 million per year. The initially planned capacity of the solar park was 2 MW.

“In the context of rising energy prices and budgetary constraints, energy independence is one of the major objectives we are focusing on. The investment in a photovoltaic park at Cluj Airport, from non-reimbursable funds, is a notable achievement and creates the premises for financial stability and achieving energy independence,” said Cluj County Council President Alin Tișe.

Gearing up for rising emissions costs

The airport’s General Manager David Ciceo stressed that heat pumps are also part of the plan to decarbonize and increase energy autonomy. President of the Board of Directors Viorel Federiga noted it is an important step toward meeting new international requirements.

For instance, the EU plans to extend the EU Emissions Trading System (EU ETS) to all flights from the European Economic Area (EEA). Currently it only covers the flights within the region and toward the United Kingdom and Switzerland. A scheme called EU ETS 2, to be launched in 2027, will include buildings and road transportation.

Within its efforts to reduce carbon emissions, Cluj International Airport added another electric bus to its vehicle fleet, to take passengers to and from aircraft. It can carry 110 people. The bus, which cost EUR 830,000, features a battery that allows for an autonomy of over 300 kilometers.

The airport projected the number of its passengers this year at 3.4 million.

Bajramović: Investments of BAM 1.4 billion needed for distribution grids in BiH

Necessary investments in Bosnia and Herzegovina’s electricity distribution grids by 2030 amount to BAM 1.4 billion (EUR 716 million), according to Zijad Bajramović, chairman of the Bosnia and Herzegovina committee of the International Council on Large Electric Systems (CIGRE).

The growing installation of power plants utilizing renewable energy sources is creating congestion in transmission and distribution networks, so the limited available capacity for their connection is an issue across the entire region, Zijad Bajramović told state news agency Fena. Nezavisne Novine republished the report.

An additional burden on the distribution network is expected from the electrification of transportation and increased electricity use for heating and cooling.

Energy storage is a solution for the problems emerging in the grid

Bajramović explained that new 110 kV substations are necessary, as is the completion of the ongoing transition to the 20 kV voltage level. Attention should also be paid to integrating prosumers, especially the households that both produce electricity, with solar panels on their roofs, and consume it.

He highlighted balancing as well as maintaining voltage conditions and supply quality as the main challenges from the rise in renewable electricity capacity on the grid. Energy storage is a solution for the issues.

Batteries can prevent renewables generation curtailments

Bajramović expects battery energy storage systems to play an increasingly significant role in relieving network congestion.

BESS, in his words, are a flexibility tool for absorbing excess generation locally, and temporarily easing the pressure on the transmission grid. They can prevent curtailments of power generation from variable renewable sources, he added.

Bajramović recalled that calculations have showed batteries of 225 MW / 450 MWh in total would be necessary to connect 1,500 MW of solar power capacity and 1,000 MW of wind power to the transmission network.

An increase in distribution network tariffs would provide funds for investment in strengthening and modernizing the distribution network, in his view.

Batteries are being installed at a rapid rate around the world as well as in the region. Not only private companies, but also state-owned utilities such as Romania’s Hidroelectrica and Montenegro’s Elektroprivreda Crne Gore (EPCG) are investing in such projects.

Abu Dhabi’s Mubadala buys into renewables developer Rezolv Energy

Mubadala Investment Company, a sovereign investment fund from Abu Dhabi, is acquiring a stake in Rezolv Energy, a major renewable energy investor in Romania, which is developing the largest solar park in Europe.

Mubadala is setting up a joint venture with Rezolv Energy’s owner, sustainable infrastructure investment fund Actis, for joint control of the firm, whose ongoing projects in the country exceed 2 GW, according to a report by Profit.ro.

The Mubadala-Actis joint venture, which has received the green light from the European Commission, will be created through the purchase of shares and securities.

Mubadala, with assets under management of USD 300 billion as of the end of 2024, is wholly owned by the government of Abu Dhabi, the United Arab Emirates (UAE).

The transaction has been cleared by the European Commission

Rezolv Energy’s ongoing projects in Romania include the construction of a photovoltaic park with an installed capacity of 1,044 MW in Arad County, called Dama Solar. Once in operation, it is expected to be the largest solar park in Europe. The investment envisages a battery energy storage system (BESS) with 500 MW of operating power.

Rezolv Energy is developing the 1,044 MW Dama Solar project and over 1 GW of wind farms in Romania

Its portfolio in Romania also includes a 600 MW wind project in Constanța county and a 461 MW wind park in Buzău county. The company has already signed a grid connection agreement for the facility in Constanța.

The company won four contracts for difference (CfD), for a total capacity of 951.2 MW, in the first two auctions organized by the Romanian Ministry of Energy, according to Profit.ro.

Rezolv Energy was launched by Actis in 2022, with an initial investment of EUR 500 million. It is now active in Romania, Croatia, the Czech Republic, Luxembourg, Bulgaria, and Slovakia, with a total portfolio of 2.5 GW of solar and wind projects.
