Sarajevo rolls out fully digital system to track air-polluting emissions

Sarajevo, the capital of Bosnia and Herzegovina, has developed a register of air-polluting emissions and an information system to track pollutants. The register aims to reduce air pollution in Sarajevo, which very often tops the list of the world’s most polluted cities.

The project to develop the emissions register and the air-pollutant information system for the Sarajevo Canton took two years, according to the government of the Sarajevo Canton. During that period, comprehensive data were collected on various air pollution sources, including home fireplaces, boiler rooms, industry, traffic, and agriculture.

In creating the register, nearly 100,000 individual emission sources were analyzed. The emissions of all pollutants from those sources were calculated in line with the European Environmental Protection Agency (EPA) standards.

The project has created emissions distribution maps for key pollutants

Compared with previous versions, the new register offers significant improvements. It uses the latest methodologies for the spatial distribution of emissions and data verification, complemented by the establishment of a central GIS database and an interactive web portal.

For the first time, the public can compare emissions data for different pollutants on a high-resolution spatial grid (100×100 meters). In addition to the detailed register of emissions, distribution maps for key pollutants, including particulate matter (PM10), sulfur dioxide (SO2), and nitrogen oxides (NOx), are also available.

The information system is set to be publicly available within a month

According to the government, the system allows for the identification of areas with excessive air pollution. A robust emissions register serves as a foundation for strategic financing of projects aimed at improving air quality, including implementing the Strategy for Limiting the Use of Coal and Other Solid Fuels in the Sarajevo Canton (2023-2033), the government added. The strategy was adopted in February 2024.

The new emissions register and air quality categorization map will provide essential data inputs for future planning and strategies across various sectors, including spatial planning, energy, transportation, and healthcare.

Jansson: Air pollution remains one of the most urgent public health challenges in Sarajevo

Birgitta Jansson, deputy head of development cooperation at the Swedish Embassy in BiH, highlighted air pollution as one of the most urgent public health and environmental challenges in the Sarajevo Canton.

“By taking a pioneering step to make environmental data publicly accessible, the canton is enabling transparent, informed, and long-term action toward cleaner air and climate neutrality – and Sweden is proud to support this important initiative,” she noted.

The Prime Minister of the Sarajevo Canton, Nihad Uk, stressed that the new register allows the government to plan measures more accurately, apply for international funding, and make sustainable decisions based on relevant data.

Softić Kadenić: A unique project in BiH

The Minister of Justice and Administration of the Sarajevo Canton, Darja Softić Kadenić, described the project as unique in BiH, since for the first time it introduces a fully digital, accurate, and comprehensive system for monitoring annual emissions into the air.

It is placing Sarajevo Canton among the more advanced European cities, she added.

According to Raduška Cupać, head of the Energy and Environment Sector at UNDP in BiH, the system is more than a technical tool – it is a strategic asset that empowers institutions, companies, and citizens to take concrete steps toward environmental protection.

The register was developed by a consortium of companies Ceteor, E3, and GDI.

Europe has record battery storage capacity growth in 2024 but expansion slows

New battery storage installations last year in Europe came in at an all-time high 21.9 GWh in capacity, though the leap wasn’t as impressive as in the previous years. The total reached 61.1 GWh. “If Europe has already entered the solar age, the battery storage age is just beginning,” said Walburga Hemetsberger, CEO of SolarPower Europe, which issued the annual report.

Europe marked the eleventh consecutive year of record-breaking battery storage installations – in capacity terms, the addition was 21.9 GWh. According to SolarPower Europe’s update, the new capacity was 15% bigger than in 2023, after effectively doubling for several years in a row.

The battery fleet ended December at 61.1 GWh. The growth rate in 2024 was 56%, compared to the 94% registered one year before.

The region that was tracked consists of the European Union, United Kingdom and Switzerland. The EU alone closed 2024 with 18.5 GWh in newly installed battery storage capacity.

“If Europe has already entered the solar age, the battery storage age is just beginning. With solar energy mainstreaming across the continent, now is the time for European decision makers to put batteries at the centre of a flexible, electrified energy system,” the organization’s Chief Executive Officer Walburga Hemetsberger stated.

She urged the European Commission to double down on its efforts and adopt an action plan as part of a broader energy system flexibility package. “The recent electricity outage in the Iberian Peninsula is a stark reminder of why this is important,” Hemetsberger pointed out.

BESS projection puts EU likely below 2030 target

In the most likely scenario, 29.7 GWh of battery storage will be installed this year, translating to a 36% annual growth in new capacity and 49% in total. The report anticipates a sixfold increase to 118 GWh added in 2029. It would bring the entirety of battery energy storage systems (BESS) to 399 GWh, of which 334 GWh in the EU.

However, it is far below the levels required to meet flexibility needs in a renewables-driven energy system, the annual report’s authors warned. A study showed that the EU needs 780 GWh by 2030 to fully support the transition.

This year the share of the new front-of-meter BESS, in the utility scale segment, is seen at 55%, against last year’s 40%. The absolute level would nearly double. As for behind the meter, commercial and industrial (C&I) systems grow to 12% from 10% of the new fleet while residential installations decline from 50% to 33% in 2025.

Drop in power prices from crisis levels faded appeal of battery storage capacity

Residential battery deployment declined by 11% in 2024 after years of rapid growth. The report attributes it to the drop in electricity prices when the energy crisis subsided, the removal or reduction of subsidies in key markets and a parallel decline in the deployment of residential solar power units.

Home batteries account for 57% of the whole cumulative level.

New large-scale grid batteries surged 79% against 2023, marking a turning point for utility-scale storage.

Last year new C&I installations were 17% bigger, remain below their potential and holding at one tenth of the whole capacity for several years now, the document shows. Companies in the segment generally invest in battery storage to maximize self-consumption from on-site photovoltaics, avoid peak demand charges and reduce reliance on backup diesel generators.

Additionally, solar and storage allow businesses to meet corporate sustainability targets by reducing carbon footprint of operations. Lastly, the electrification of production processes, heating, and transport fleets is driving unique use cases and a need for storage.

Spain lags but seen rebounding, reaching top five in 2025

The top growers and their positions in the chart were the same as in 2023: Germany (6.2 GWh), Italy (6 GWh), the United Kingdom (2.9 GWh), Austria (1.1 GWh) and Sweden (1 GWh). Together they had a 78% share in both new and cumulative installations.

Germany added slightly less on an annual scale than in 2023 amid a drop in newly installed residential units. Italy’s home battery segment also decreased, but the large-scale segment’s capacity surge brought the market to new heights. The UK experienced a temporary slump due to project delays at the large-scale level.

Last year Spain added less than 250 MWh in battery storage capacity, making it the 14th-biggest market in Europe. Overall it reached 1.7 GWh, of which 90% were small-scale systems.

The country’s new battery installations were 41% lower than in 2023. The Spanish market has been declining since 2022, but it is expected to enter the top five this year, with 1.3 GWh, amid a utility-scale segment’s revival.

BESS market requires level playing field

SolarPower Europe said the authorities need to encourage the participation of hybrid projects of solar and BESS in renewable energy auctions.

“Contracts for difference must be settled based on energy production rather than energy injection. This will allow the asset operator to receive the CfD for the PV asset while generating additional market-based revenues from the BESS. These extra revenues will eventually lead to lower bids from developers and reduce the support costs for society,” the document reads.

The EU must ensure transmission system operators (TSOs) procure balancing services in market-based procedures in which batteries can compete on a level playing field, the organization added. Some EU markets still rely on bilateral contracts that limit fair competition and exclude smaller storage assets, it underscored.

Croatia’s HEP to install first floating PV plant on reservoir of HPP Dubrava

Hrvatska Elektroprivreda is preparing to build its first floating solar power plant, with a capacity of 12 MW. It will be installed on the reservoir of its Dubrava hydropower plant.

State-owned company Hrvatska Elektroprivreda (HEP) has already installed one photovoltaic facility near HPP Dubrava, but it was ground-mounted. The Donja Dubrava PV plant has a capacity of 9.9 MW.

Combining hydro with solar into hybrid power plants is an increasingly popular solution for power companies. HEP is already building a hybrid energy park, the first in the country. It is located near the town of Benkovac.

The floating photovoltaic plant would have a barrier against waves and waste

Back in 2023, the company presented plans to build a floating PV plant as part of HPP Dubrava, on the Drava river. It has a capacity of 79.78 MW, while the average production, which started in 1989, is 350 GWh.

It is located near the town of Prelog, in northern Croatia.

HPP Dubrava is the last on in a cascade three multi-purpose HPPs on the Drava river. In addition to producing electricity, they contribute to water supply, flood and soil erosion protection, irrigation and drainage, and host roads. Now they are set to add solar panels.

HEP has submitted an application to the Ministry of Environmental Protection and Green Transition for the evaluation of the need for an environmental impact assessment (EIA) for its floating solar project.

The facility will be attached to the lake bottom with 62 anchors

It would be installed on a floating platform consisting of a prefab structure, buoys filled with expanding polystyrene foam, and an anchoring structure, the request reads.

The power plant would also have a barrier against waves and floating waste. The floating platform and the barrier are planned to be attached by steel ropes to the bottom of the lake at 62 spots.

The project comprises 19,812 solar panels with a capacity of 615 W, spanning 8.9 hectares. More details on the project can be found in an environmental protection report issued in October 2024 and updated in March by the Hrvoje Požar Energy Institute.

Electricity prices for Slovenian firms among highest in EU in 2024

Last year, Slovenian households had cheaper electricity than the European Union average while the tariffs for other categories of consumers, including businesses, were among the highest in the EU, according to an analysis by Slovenia’s transmission system operator ELES.

The analysis, conducted by ELES CEO Aleksander Mervar, also showed network fees are significantly lower than the EU’s average.

Slovenia is in the bottom third of the list of the 27 member countries. As for its neighbors, domestic prices were higher than in Hungary and Croatia, and lower than in Austria and Italy, Naš Stik reported.

Last year, Bulgaria had the lowest prices in the EU, followed by Malta, Luxembourg, Hungary, and Croatia. When measured against purchasing power, prices in Slovenia are in the lower half of the list.

The Government of Slovenia has capped electricity prices for households

The analysis attributes the lower tariffs for households mainly to measures that the Government of Slovenia introduced. The two main interventions were setting a maximum price for 90% of consumption, and freezing the payment of a fee for subsidizing electricity production from renewables and high-efficiency cogeneration.

From January 1 to October 31, the maximum price was 8.2 eurocents per kWh in the lower tariff and 11.8 eurocents per kWh in the higher one. They were the maximum prices for 90% of consumption, while the remainder was set by suppliers in line with the market conditions.

Without government measures, the annual bill of the average Slovenian household, with an annual consumption of 4,000 kWh, would be higher by EUR 345.89 or 45.77%, according to the calculation.

ELES denies network fees impacted competitiveness of firms

The conditions for businesses were different. Prices for commercial and industrial consumers were among the highest in the EU. However, the domestic average was lower than in neighboring countries.

Businesses in Serbia experienced a similar issue last year.

ELES denied the claim by the Chamber of Commerce and Industry of Slovenia that high network fees lowered corporate competitiveness. The company argued they were significantly lower for commercial consumers, by 36.5% to 49%, than the EU average.

In addition, network fees are as much as 53% below the level in the countries surrounding Slovenia, according to the ELES analysis.

Network fees for households in Slovenia are among the lowest in the EU.

EU outlines measures to end Russian gas, oil imports by end-2027

The European Commission set out a plan to phase out by the end of 2027 the purchases of Russian natural gas, including in the form of LNG, and oil. The package includes proposals aiming to replace Russian nuclear fuel and materials as well.

The European Union will end its dependency on Russian energy by stopping the import of Russian gas and oil and phasing out Russian nuclear energy, while ensuring stable energy supplies and prices, the European Commission said. Its new REPowerEU Roadmap targets full energy independence from Russia.

Since Russia’s invasion of Ukraine in 2022, the EU was lowering the share of Russian fossil fuels under the REPowerEU plan and via sanctions. However, Russian gas imports rebounded last year by 18%, led by Italy, Czechia and France. The commissioners argued that the “overdependency on Russian energy imports is a security threat” and called for new coordinated actions.

Von der Leyen: It is now time for Europe to completely cut off its energy ties with an unreliable supplier

“The war in Ukraine has brutally exposed the risks of blackmail, economic coercion and price shocks. With REPowerEU, we have diversified our energy supply and drastically reduced Europe’s former dependency on Russian fossil fuels. It is now time for Europe to completely cut off its energy ties with an unreliable supplier. And energy that comes to our continent should not pay for a war of aggression against Ukraine. We owe this to our citizens, to our companies and to our brave Ukrainian friends,” European Commission President Ursula von der Leyen stated.

The volumes of imported Russian gas fell to last year’s 52 billion cubic meters from 150 billion in 2021. The share of Russian gas imports dropped from 45% to 19%. All imports of the country’s coal have been banned by sanctions. Russian oil imports have shrunk from 27% at the beginning of 2022 to the current 3%.

Member states need to roll out national plans by end-2025

The new measures have been designed to preserve the security of energy supply while limiting any impact on prices and markets. They would be applied in parallel to advancing the energy transition.

“Last year we in the EU paid EUR 23 billion to Russia for our energy imports. That is EUR 1.8 billion per month. This needs to stop,” European Commissioner for Energy Dan Jørgensen stressed.

The administration in Brussels expects to replace up to 100 billion cubic meters of natural gas by 2030, which means a decrease in demand by 40-50 billion by 2027. It sees an increase in liquefied natural gas (LNG) capacities by 200 billion cubic meters by 2028, which is five times more than current EU imports of Russian gas. The EU still hasn’t imposed sanctions on Russian LNG.

Member states will be asked to prepare national plans by the end of this year, the announcement reveals. All the measures will be accompanied by continuous efforts to accelerate the energy transition and diversify energy supplies, including via the aggregation of gas demand and a better use of infrastructure, according to the document.

Administration in Brussels intends to tackle Russian shadow tanker fleet carrying oil

The European Commission said the proposed measures would improve the transparency, monitoring and traceability of Russian gas.

“Crucially, new contracts with suppliers of Russian gas (pipeline and LNG) will be prevented, and existing spot contracts will be stopped by the end of 2025. This measure will ensure that already by the end of this year, the EU will have slashed by one third remaining supplies of Russian gas. The commission will further propose to stop all remaining imports of Russian gas by the end of 2027,” the plan reads.

Under the roadmap, the commission will put forward new actions to address Russia’s shadow fleet transporting oil. It said the vessels are circumventing sanctions and the international oil price cap.

EU depends on Russia for quarter of its uranium conversion, enrichment needs

As regards nuclear, the proposals coming next month cover enriched uranium and supply contracts co-signed by the Euratom Supply Agency (ESA) for uranium, enriched uranium and other nuclear materials. The EU intends to increase its production of medical radioisotopes.

“While diversification efforts might create uranium and fuel price volatility over access to uranium supply on global markets, major impacts on electricity prices are unlikely as the price of nuclear fuel and related services represent only a small portion of the final cost of electricity from nuclear power plants,” the plan adds.

The EU intends to increase its production of medical radioisotopes

More than 14% of uranium was sourced in the EU from Russia in 2024. The commissioners highlighted the concentration of uranium conversion and enrichment services – needed to transform processed uranium into the material for nuclear fuel manufacturing – in a limited number of companies.

In 2024, around 23% of the whole EU demand for uranium conversion services and almost 24% of enrichment was covered by Russia.

While more than 85% of uranium is produced in Kazakhstan, Canada, Australia, Namibia, Niger and Russia, uranium mines currently operate in many countries and unmined deposits exist in some EU member states.

It will take years to make use of domestic, other Western resources

European enrichment companies have expansion plans but the first new enrichment installation is not expected earlier than 2027.

“Moreover, the global uranium conversion industry is facing obstacles in ramping up production due to technological complexity and market uncertainties, and new conversion capacities are currently announced only for early 2030s. The EU’s nuclear sector also continues to rely on Russia for some spare parts and maintenance services,” the European Commission said.

EEB: Replacing Russian gas with US gas is senselless

The European Environmental Bureau (EEB) noted that imports of Russian gas including LNG rose 18% in 2024 despite no growth in demand.

Numbers of shadow LNG tankers from Russia have also increased, as have indirect imports of Russian energy via third countries, it added. Plans to tackle the shadow fleet are vague, the organization claimed. It went on to label the United States a clearly unreliable trade partner.

“Phasing out Russian coal and gas only to replace it with a dependence on US fracking gas is not in the EU’s security or financial interests. EU countries should instead focus on accelerating their deployment of wind and solar energies. The technologies to move to 100% renewable energy are available,” EEB’s Policy Manager for Climate and Energy Luke Haywood underscored.
