Upgrade for prosumers to avoid grid curtailments costs up to EUR 1,000

To use electricity from their photovoltaic systems in periods when grid operators disconnect them to stabilize the system, citizens can install equipment that costs EUR 300 to EUR 1,000. Cyprus passed a bill enabling prosumers to switch to a zero-export mode.

Cyprus, the only non-interconnected European Union member state, is struggling to maintain the stability of its electricity system. Rapid growth of solar power capacity is increasing the episodes of overloads, when grid operators have to curtail their production. At the same time, sometimes sudden weather changes push production to a critically low level, which can also cause outages before oil-fired power plants step in to cover the deficit.

Still, the island country passed amendments last week to protect the right of prosumers to an interrupted power supply for their own needs. On the other hand, implementation isn’t cheap, and for some of them it would not be cost-effective.

Upgrading a PV system with a zero-export mode is not cost-effective if no one is usually home during work hours

Minister of Energy, Commerce and Industry George Papanastasiou said prosumers need to upgrade their photovoltaic systems to be able to keep consuming their electricity during curtailments. A switch for cutting off the solar panels from the grid, and leaving them directly connected to the home, costs some EUR 300, he added. But a prosumer will need to pay EUR 1,000 if the inverter doesn’t support the conversion, the minister explained.

Owners of PV systems need to calculate the curtailment costs and compare them to the investment that enables operating them in a so-called zero-export mode.

If no one is home on weekdays during work hours, when solar panels generate electricity, there are no substantial benefits, unless there is also a battery. And it makes the intervention much more expensive. Conversely, the new option is much more useful for most businesses.

Cyprus is rushing to introduce energy storage capacities and expand the curtailment systems throughout the power system.

Eurowind Energy completes its 60.2 MW solar park in Romania

Eurowind Energy’s 60.2 MW photovoltaic park in Transylvania will be put into operation in late April, Minister of Energy Sebastian Burduja said. The facility is joining the almost 600 MW in new capacity funded from the National Recovery and Resilience Plan. In addition, the ministry prepared a EUR 450 million package of grants for companies for energy efficiency and self-consumption.

After 14 years of doing business in Romania, Denmark-based European Energy is materializing its first major endeavors in the country. Minister of Energy Sebastian Burduja revealed that the company’s solar power plant in Teiuş would be commissioned by the end of the month.

The location is in the Transylvania region. Eurowind Energy received EUR 15 million from the government for the project. It costs EUR 47.2 million in total, or EUR 55 million with value-added tax. Construction began a year ago. The system in Alba county will generate an estimated 104 GWh per year.

Burduja said almost 600 MW of capacity has been commissioned within the projects that Romania funds through the National Recovery and Resilience (NRRP or, in Romanian, PNRR).

Eurowind Energy has major renewables projects lined up in Romania, Bulgaria

Eurowind Energy, based in Hobro, Denmark, is one of the biggest wind and solar power developers in Romania.

The Danish company recently signed a 12-year virtual power purchase agreement (PPA) with Autoliv in Romania, for the supply of electricity from the Pecineaga wind park. Eurowind Energy is preparing to put the facility into operation.

It is also building a 238 MW solar power plant in Yambol in neighboring Bulgaria, with Renalfa IPP. They plan to add wind turbines and batteries.

EUR 450 million available for firms for energy efficiency, self-consumption

At the same event, Burduja said the ministry is launching two calls worth EUR 450 million combined. They are intended for support to the energy-intensive industry.

The package for is for companies. It consists of EUR 150 million for energy efficiency – the replacement of outdated equipment – and more than EUR 300 million for the production of electricity for self-consumption.

The Ministry of Energy has set an extremely ambitious target of 2.5 GW of new capacity to be put into operation this year, Burduja stressed. It is two times more than in 2023. Active energy storage capacity is nearing 400 MWh, he added.

In the energy efficiency call, fims can receive as much as EUR 30 million each from the Modernisation Fund. The self-consumption segment is for the ones with available land and projects for photovoltaic parks or even wind farms and micro hydropower plants.

According to the International Renewable Energy Agency (IRENA), Romania increased its solar power capacity at the end of last year by 57% to 4.7 GW. Most of it is from prosumers. The wind power segment is picking up, but slowly, after a stagnation that began a decade ago.

Croatia changing law on renewables – new rules for prosumers, decentralized power production

The Government of Croatia has adopted the amendments to the law on renewable energy sources and high-efficiency cogeneration. They change rules for consumers producing electricity for self-consumption, facilitate the establishment of citizen energy communities and regulate decentralized energy production.

The amendments align the Croatian legislation with the European Union’s Renewable Energy Directive and bring benefits to citizens, entrepreneurs, and investors, the Ministry of Economy said.

One of important innovations is a new scheme for the production of energy for self-consumption. Instead of the current net metering mechanism, the new law introduces net billing. It values more fairly the surplus electricity that prosumers deliver to the grid, according to the ministry.

The grid costs charged to prosumers will be aligned with the actual amount of electricity that they take from the grid

Consumers – citizens and entrepreneurs that produce energy for their own needs, will pay grid costs matching the amount of electricity they actually take from it, enabling a sustainable and fair system for all users, the ministry added.

Existing prosumers will have ten years for the transition to the new scheme.

The bill enables the production of electricity for self-consumption in remote locations, provided that all metering points are registered with the same consumer. The ministry expects the measure to pave the way for greater investments, flexibility, and decentralized energy production.

Waste separation is a condition for granting incentives for waste incineration

The rules for establishing citizen energy communities have been simplified, to further strengthen their role in the energy transition. The amendments stricten the criteria for the sustainability of biofuels and they prohibit incentivizing the incineration of waste not from a system of separate collection.

The upcoming law sets the basis for a plan for the development of electricity infrastructure and storage capacities. It will create the conditions for greater integration of renewable energy sources into the grid, the ministry stressed.

“With this law we are taking an important step forward in the energy transition, ensuring a balance between the interests of citizens, the economy, and the energy system, and creating the foundations for a sustainable development of the Croatian energy sector in the long term,” Minister Ante Šušnjar stated.

Activists in northeastern BiH to obstruct Majevica lithium mining project

Switzerland-based Arcore and Canadian company Rock Tech Lithium are planning to excavate lithium, boron and magnesium ore and process it near Lopare in northeastern Bosnia and Herzegovina. Citizens and activists from the area surrounding the Majevica mountain are opposing the project, together with people from the border area in neighboring Serbia.

Supported by the local authority, citizens from both entities in BiH and environmental activists have gathered in the city of Bijeljina at another protest against the plans to mine lithium as well as rare metals. Among the participants were the inhabitants of border areas in neighboring Serbia, where Rio Tinto is developing a controversial project for mining and processing jadarite, a unique lithium mineral. Based on the results of its exploration, Swiss firm Arcore submitted a request to the Government of the Republic of Srpska in February for a concession for a mine on the Majevica mountain.

Around the same time, it also agreed with Canadian company Rock Tech Lithium to establish a joint venture that would include the location in northeastern BiH.

Investors want to produce lithium sulfate on site

According to the partners, they plan to start delivering in 2030 the lithium sulfate produced on site to Rock Tech Lithium’s future converter in Guben, Germany. The facility would process the raw material to get battery-grade lithium hydroxide.

The lithium, boron and magnesium deposit is in Lopare municipality, they added. The investment in Brandenburg was in the final financing phase when the agreement was signed, the two companies have revealed. They estimated that 600,000 tons of lithium carbonate equivalent can be obtained from the proposed mine.

The next step is to complete the prefeasibility study. Rock Tech Lithium holds 75% of the JV. Arcore claims that the location contains at least two million tons of lithium carbonate and that it can be exploited for 65 years.

In addition, President of the Republic of Srpska Milorad Dodik said in early March that the entity and Hungary are preparing an agreement on mining rare metals.

Bijeljina, Lopare and Majevica are all in the Republic of Srpska. The country’s other entity is called the Federation of Bosnia and Herzegovina, where activists in the nearby city of Tuzla and municipalities like Čelić are warning of the potential environmental impact of lithium mining and other shady projects.

Environmentalists demand Majevica to be protected as nature park

Environmentalist groups earlier requested from the Republic of Srpska to impose a moratorium on geological exploration and mining on the mountain.

Environmentalist associations submitted a petition with over 6,000 signatures for a moratorium on geological exploration and mining in Majevica

“This gathering was envisaged to have a regional character as today the citizens of several cities and municipalities have come together. Entire northeastern BiH is in the scope, as Majevica is our joint mountain. We all share the same water, same air and we live on the same land. We organized a civic initiative and we collected more than six thousand signatures and demanded for Majevica to become a nature park,” said Snežana Jagodić Vujić from the Eko put association based in Bijeljina.

In her opinion, the rich part of the world is building for its clean energy while destroying the environment and people in the poorer part of the world.

Semberija plain and Sava basin area are under threat as well

Head of the Municipality of Lopare Rado Savić said opening a mine in Majevica would jeopardize Lopare as well as Semberija, Posavina – areas around the river Sava, all wildlife downstream from its tributary Gnjica, and the Janja, which flows into the Drina river. “Unless there are other development projects, we don’t need mining either,” he added.

Machines shall not pass through any village, Adi Selman from Tuzla-based activist group Karton revolucija told the crowd. “We promise tonight that, if it is necessary, we will be chasing them away with our pickaxes and hoes and that, even if we are left all alone in this world, we will never give up on the fight to save our Majevica, Semberija and Posavina”, he stressed.

There is no rich mining town in the world and no lithium mine near a populated place or in a nature park, Bijeljina Mayor Ljubiša Petrović claims. “We won’t allow a handful of strongmen to destroy, for other people’s interests and profits, what was created for generations – our water, land and life,” he stated.

Bulgaria suspends ill-designed solar energy support program

The Ministry of Energy of Bulgaria doesn’t intend to publish the second call for subsidies for households for solar panels with batteries and solar collectors. The program is partly covered by the European Union’s Recovery and Resilience Facility, so now the country risks losing the funds.

The Ministry of Energy of Bulgaria told Kapital that it does not plan to launch a second procedure to support households in purchasing and installing rooftop photovoltaic panels and solar water heaters. The measure was one of the few for citizens in the National Recovery and Resilience Plan (NRRP) rather than businesses or municipalities.

Through the first call, 1,500 households were selected for grants, worth some EUR 20.5 million in total. There is EUR 123 million for the entire scheme, called Support for Renewable Energy for Households. The solar power panel segment includes an option to install batteries as well.

Procedure too complicated

Initially there were fears that there would be more applications than the sum can cover, the article adds. But the procedure turned out to be so complicated that few people actually submitted documentation, the news outlet wrote. So now Bulgaria is about to lose the funds, after the European Commission already blocked the second NRRP tranche late last year.

The Ministry of Energy said it expects all the remaining contracts from the first round to be signed by the end of the month.

The program covers up to 70% of the costs for PV panels and 100% for solar collectors

According to Balin Balinov from Greenpeace, the government is once again demonstrating lack of commitment when it comes to energy poor households.

The program covers up to 70% of the costs for PV panels and 100% for solar collectors. But beneficiaries must buy them on their own and get reimbursed afterward. Notably, people who can afford such devices don’t want to deal with the bureaucracy, the report adds.

Installers struggling with backlogs amid tight deadlines

Moreover, Balinov said, there are hardly any firms available at the moment for installing solar panels, and the deadlines are short. Another issue is the lack of a net metering mechanism for rooftop and balcony photovoltaics. In such a setting, the electricity that beneficiaries generate would be subtracted from their bills.

The draft Law on Energy from Renewable Sources, currently in procedure in the National Assembly of Bulgaria includes the introduction of virtual net metering for prosumers and renewable energy communities. The deadline for approving an application for the installation of a solar power system of up to 20 kW would be just one month, the ministry pointed out.

Moreover, to get a grid connection, prosumers with up to 10.8 kW would only be required to notify the operator.

Romania’s Hidroelectrica picks contractors for 36 MW battery system at its only wind farm

Prime Batteries Technology and Enevo Group won Hidroelectrica’s tender for the installation of a battery energy storage system of 36 MW with a two-hour duration at the power utility’s Crucea Nord wind park.

A renewable energy hub is in the making in the small communes of Crucea and Pantelimon in the Dobruja (Dobrogea) province in Romania’s east. The area is home to state-owned hydropower producer Hidroelectrica’s only wind farm, Crucea Nord, but it includes several sites for projects of other companies, too.

The facility has been operating at a significant loss due to unfavorable balancing requirements. Hidroelectrica launched a small battery first, only to publish a tender four months ago for contractors for a system of 36 MW in operating power and 72 MWh in capacity.

Contract is worth EUR 16 million excluding VAT

The news is that the utility signed a EUR 16 million deal with Prime Batteries Technology and Enevo Group, the consortium with the best bid. The deadline is 12 months. Hidroelectrica initially estimated the investment at EUR 20.3 million plus excluding value-added tax.

Prime Batteries manufactures lithium ion batteries and provides energy storage solutions for the automotive, smart grids, and industrial sectors. The startup is headquartered in Cernica near Bucharest. The other company is Romanian as well.

Primary idea is to reduce imbalances

Crucea Nord, commissioned in 2014, has 108 MW in capacity. The battery energy storage system needs to be built at the substation.

“The primary objective of this investment is to reduce internal imbalances at the wind farm within Hidroelectrica’s portfolio, provide system balancing services for the national energy grid, improve the performance of the wind turbines, and decrease the wear on the electromechanical systems of the turbines,” Hidroelectrica said. It would be its first lithium ion battery.

The company operates 188 hydropower plants with a combined capacity of 6.4 GW.

Romania and neighboring Bulgaria are racing to boost battery capacity within deadlines for subsidies from the European Union. Both achieved robust growth rates in the solar power sector, so balancing needs are also surging.
