Croatia earmarks EUR 1.6 billion for Social Plan for Climate Policy

Croatia plans to achieve an efficient and just green transition by implementing its EUR 1.6 billion Social Plan for Climate Policy.

The Ministry of Environmental Protection and Green Transition has presented the Social Plan for Climate Policy and the European Union’s upcoming Emissions Trading System 2 (EU ETS 2) in Croatia’s capital Zagreb.

The event was organized as part of the process of developing the country’s Social Plan for Climate Policy. According to the ministry, the document outlines the green transition and includes measures and investments that would benefit vulnerable households, micro businesses, and users of transportation services.

The plan is being prepared within the framework of the Social Fund for Climate Policy, which is part of the EU’s Fit-for-55 legislative package. The aim is to reduce greenhouse gas emissions by 55% by 2030 from the 1990 level.

The social plan will be funded with proceeds from EU ETS 2

The new EU ETS 2 will cover CO2 emissions from buildings, road traffic, and small firms. Funding for the social plan will be secured from proceeds from the supplementary carbon pricing mechanism.

Minister Marija Vučković noted that after the public debate is over, the Social Plan for Climate Policy needs to be sent to the European Commission for adoption.

“With more than EUR 1.6 billion, our goal is to secure an efficient and just green transition that won’t leave behind the most vulnerable members of our society – households at risk of energy poverty, micro enterprises with limited adaptation capacities, but also the citizens that have difficulties accessing public transportation,” she pointed out.

The ministry is aware of the challenges that the transition carries, so it places special focus on mitigating socio-economic consequences and preventing risks affecting the most vulnerable people, as well as on education.

The plan defines various measures

The plan includes various measures. Some examples are renovating family houses with the worst energy performances, improving the availability of public transport in suburban, rural, and remote areas, subsidizing the purchase of vehicles with zero emissions, and providing direct financial incentives.

Representatives of the ministry Ana Juras and Predrag Božac described the operation and the establishment of the new part of the Emissions Trading System and presented the sectors that it would cover. They also spoke about the first round of measures and investments from the plan.

In another presentation, the audience learned the effect of EU ETS 2 on the prices of fossil fuels, the ministry said.

Croatia’s Pag island to produce green hydrogen using wave energy

The island town of Novalja could become one of the first in Croatia to begin the production of green hydrogen, and a rare example in the region. Moreover, the local authority would utilize innovative technology.

Croatia adopted its national strategy for hydrogen until 2050 in March 2022. The first hydrogen production facility could be installed in Križevci, according to a report from last year.

The local authority in Novalja on the island of Pag said it started its ambitious and innovative Zero Emission Corridor (ZEC) H2 project with the goal of establishing the production and distribution of green hydrogen – using only renewable energy.

The project represents a key step in the small town’s transition towards sustainable development and energy independence.

The construction of a pilot facility in the Žigljen port has already started

The preparations for the project included an analysis of suitable locations, including the ports of Novalja, Žigljen, and Tovarnele. As the first concrete step, the local authorities initiated the construction of a pilot plant in the port of Žigljen.

The facility would use innovative domestic technology for the generation of electricity from sea waves, the announcement reads. It would be used to power water electrolysis for the production of green hydrogen.

The facility is expected to become fully operational by 2027.

The ZEC H2 project would make Novalja an energy independent, emission-free town by 2030. The project’s main goals are to significantly reduce greenhouse gas emissions, increase energy efficiency, and encourage the use of renewables.

The construction of the pilot plant is financed through an EU program

The green hydrogen and excess energy would be used to power electric chargers, public transport and utility vehicles, public lighting, and city buildings.

The construction of the pilot plant is financed through the European Union’s Interregional Innovation Investments (I3) Instrument while substantial grants were secured from EU funds.

The ZEC H2 project confirms Novalja’s commitment to sustainable development, environmental protection, and the development of innovations in the green energy sector, the town’s leadership said.

According to data from August last year, there were 32 green hydrogen projects in Croatia. One of them was for the production of hydrogen using sewage sludge.

Croatia discusses installation of small modular reactors with US

Croatian and United States officials have discussed the possibilities for energy cooperation to diversify the energy supply in Central and Southeastern Europe. Croatia has expressed particular interest in joint work in the nuclear energy sector.

On the sidelines of the 10th summit meeting of the Three Seas Initiative, held in Warsaw, Croatian Prime Minister Andrej Plenković met with United States Secretary of Energy Chris Wright. Minister of Economy Ante Šušnjar attended the discussion as well and separately sat with a delegation from the Nuclear Energy Institute, based in Washington.

Of note, at the same event, Wright invited Central European countries to abandon the European Union’s energy and climate policy and join his country on “team energy freedom.”

Talks between the two delegations covered various topics, including the expansion of the liquefied natural gas (LNG) terminal on the island of Krk, development of gas infrastructure toward Hungary and Slovenia, and strengthening the security of energy supply in Central and Southeastern Europe.

The two sides have discussed the enhancement of energy independence for Croatia and Southeastern Europe

According to Croatia’s Ministry of Economy, representatives of the two countries exchanged views on further opportunities for US involvement in projects focused on diversifying energy sources and strengthening the region’s energy resilience.

Croatian officials highlighted the importance of ongoing cooperation with the US, particularly regarding the diversification of energy supply and the enhancement of energy independence for Croatia and Southeastern Europe, the ministry underlined.

Minister Šušnjar and Maria Korsnick, CEO of the Nuclear Energy Institute, discussed potential cooperation in the development of nuclear energy, particularly the application of small modular reactor (SMR) technology.

Šušnjar: SMRs is an alternative to existing fossil fuel sources

Šušnjar noted that nuclear energy is increasingly vital for achieving decarbonization and ensuring a stable electricity supply. Croatia has established a workgroup to analyze the potential use of nuclear energy including SMRs as an alternative to existing fossil fuel sources, he added.

“We are interested in partnering with companies that offer advanced, safe, and cost-effective solutions. The Nuclear Energy Institute is a key partner in that process,” Šušnjar said.

Croatia has been expressing interest for the past several years in the Krško 2 nuclear power project in neighbouring Slovenia.

However, Minister Šušnjar recently said his country would focus on developing its own nuclear power capabilities including SMRs.

Republic of Srpska awards concession for Trebinje 3 solar project

The Ministry of Energy and Mining of the Republic of Srpska, one of the two entities constituting Bosnia and Herzegovina, has awarded a concession to power utility Elektroprivreda Republike Srpske for the proposed Trebinje 3 solar power plant.

The Trebinje 3 photovoltaic plant would have an installed capacity of 53.63 MW and an estimated annual production of 85.5 GWh.

According to the ministry, construction is expected to be completed within the next four years. The concession has been granted for 50 years and the total investment value is BAM 84.2 million (EUR 43.1 million), the ministry said.

Before finalizing the concession contract, the concessionaire, state-owned Elektroprivreda Republike Srpske (ERS), delivered a one-off payment to the budget of the Republic of Srpska of BAM 842,049 (EUR 430,992).

Almost the entire amount of the concession fee will be allocated to the budget of the City of Trebinje

After the facility becomes operational, the concessionaire will be obligated to pay a fee of BAM 0.0055 (EUR 0.0028) per kWh of generated electricity to the budget of the Republic of Srpska. A 95% share is allocated for the budget of the city.

The concession agreement for the construction and operation of the Trebinje 3 solar power plant was signed by the Minister of Energy and Mining of the Republic of Srpska Petar Đokić, who will be among the speakers at Belgrade Energy Forum 2025 (BEF 2025), and ERS CEO Luka Petrović.

ERS already has two concessions for solar power projects

It is the third concession that the company received for solar power plants from the government. The first, for Trebinje 1, with a capacity of 73 MW, was awarded in 2020..It was followed by Trebinje 2, for 53 MW, awarded in 2022. Neither of the two PV plants has been constructed yet.

In March 2022, ERS announced Lugos Renewables was acquiring 70% ownership of the Trebinje 1 project, with ERS retaining control of the remaining 30%.

In February of this year, the Government of the Republic of Srpska approved concessions for two solar power projects. Their total capacity would be 110 MW.

Electricity system in Spain, Portugal collapses

Power was out today throughout Spain and Portugal as well as in Andorra and parts of southern France, in one of the most serious such incidents so far, on a European scale. The European Commission’s Executive Vice President Teresa Ribera and other officials from the EU and the affected countries said there are no indications of sabotage or cyberattack.

Grid operators and electricity producers are gradually restoring the power supply after a massive outage struck the Iberian peninsula today. Prime Minister of Spain Pedro Sánchez convened the National Security Council. It is one of the most serious blackouts in Europe in many years. The outage spread throughout Spain and Portugal.

Power was out in Andorra and, briefly, in parts of southern France. Transportation and telecommunications were heavily affected.

Spanish TSO Red Eléctrica de España called it a “collapse of the Iberian electricity network.” The company said it would take six to ten hours to restore it. Notably, the production system is relying almost completely on photovoltaics and wind farms at the moment, so just a few hours of solar power production remain.

The outage paralyzed major cities including Madrid, Barcelona and Lisbon and caused disturbances in the European grid. The European Commission’s Executive Vice President for Clean, Just and Competitive Transition and Commissioner for Competitiveness Teresa Ribera said there were no indications that “any kind of sabotage or cyberattack” was behind the grid collapse.

According to the Government of Portugal, the incident started from outside the country

According to the Government of Portugal, the incident started from outside the country and, apparently, in Spain.

Shares of solar, wind power production in Spain breaking records

In the spring and autumn, when there is little to no demand for heating or cooling, electricity grids in most of Europe are sometimes strained from surges in high solar and wind power production, amid a lack of energy storage and flexibility capabilities that would balance the surplus.

On April 16, the Spanish electricity system achieved total coverage for the first time with renewable energy sources. At one point during the day, wind and solar met 100.6% of demand. Then on April 21, solar power generation was equivalent to a record 78.6% of domestic demand for a moment.

Reid: The massive outage occurred while prices are negative in electricity markets across Europe

“Spanish grid operator Red Eléctrica has so far blamed a power ‘oscillation’ on the power outage. We still don’t know the cause but it looks like problems at the Spanish-French power interconnector led to the Spanish grid operator islanding their power system and I would say at this point they lost control,” said Gerard Reid, investor and strategic advisor in energy, finance and geopolitics.

It has also proven difficult to restore power with multiple black start (restart) procedures taking place, but the issue is that at the time of the blackout there were no conventional power units in operation, he pointed out. Reid added it makes the restart complicated and stressed that Europe requires enhanced grid-scale battery storage solutions, including for black start capabilities.

He also highlighted the fact that the massive outage occurred while prices are negative in electricity markets across Europe.

Of note, a grid incident last summer left much of the Western Balkans and parts of Croatia out of power for several hours.
