Court annuls environmental permits for EPBiH’s hydro projects Janjići, Vranduk

The Cantonal Court in Sarajevo overturned two decisions of the Federal Ministry of Environment and Tourism regarding the proposed Vranduk and Janjići hydropower plants.

The Janjići and Vranduk hydropower projects, with a total capacity of 36 MW, are being developed by state-owned power company Elektroprivreda BiH. The sites are on the Bosna river near the city of Zenica.

The two decisions were challenged by the Aarhus Centre in Bosnia and Herzegovina.

The Cantonal Court in Sarajevo has ruled that the 16 MW Janjići project requires a new environmental permit to move forward, news website Zenit.ba reported. Namely, the Aarhus Centre in BiH disputed the ministry’s decision in December 2021 that the existing one was valid. According to the court, the explanation was legally unsubstantiated.

The ministry didn’t take into account the ecological sensitivity of the Janjići area

The ministry also failed to acknowledge the complexity of the planned hydropower facility and that, in line with the regulations, a new permit is necessary if the deadline expires, the ruling reads.

According to the court, the ministry didn’t take into account the ecological sensitivity of the Janjići area. The location is a habitat of protected plant and animal species, among which is the otter.

Of note, in January 2022, Germany’s KfW Development Bank said it canceled the plan to finance the Janjići hydropower project with EUR 30 million. Total investment was valued at EUR 55 million.

The loan agreement between KfW and EPBiH was signed in 2014. Environmental organizations opposed the project, arguing it would flood one of the most beautiful areas around the Bosna river.

The Aarhus Convention was violated in the case of HPP Vranduk

The court also annulled the ministry’s 2023 environmental permit for the HPP Vranduk project of 20 MW.

The ministry violated several provisions of an environmental protection law of the Federation of BiH, the court stressed. By issuing the permit, it violated the right of the public to access information and participate in the decision-making process, thereby also violating the Aarhus Convention.

The environmental impact assessment (EIA) was inadequate while the environmental risks determined earlier and comments from experts weren’t taken into account, the ruling reads.

In early 2022, Austria-based Strabag won at the International Court of Arbitration in Brussels in a case against EPBiH. The panel ordered the power utility to pay EUR 16.4 million to the company.

RWE-PPC partnership starting to build 567 MW of PV capacity

Meton Energy has taken the final investment decision for two photovoltaic projects north of Thessaloniki. Through their joint venture, Germany-based RWE and Greek government-controlled utility PPC are about to start construction of 567 MW in total peak capacity.

Most of the 2 GW solar power portfolio that the top tier German-Greek partnership is developing is now materializing. RWE, holding 51% in the Meton Energy joint venture, and Public Power Corp. (PPC), the other co-owner, agreed to move to the construction phase in an investment worth EUR 418 million.

The endeavor consists of two photovoltaic projects in the Central Macedonia region in north Greece. Solar farms Kotyli and Neo Syrakio would have a total peak capacity of 567 MW, translating to 518 MW in grid connection terms.

Commissioning expected in 2027

Construction is planned to start this spring, with commissioning expected in 2027. The two sites are in the Kilkis regional unit north of Thessaloniki. Estimated annual output is equivalent to the electricity demand of more than 140,000 households.

PPC, or DEI in Greek, formally entered its largest joint venture in 2021 with German energy giant RWE. It took the domestic company less than five years to swing from deep losses to a nearly completed coal phaseout and a regional expansion at full speed. It is building some of the largest renewables and gas facilities in Europe. Moreover, PPC is transforming the two areas in Greece that rely on the solid fossil fuel and lignite-fired power plants.

RWE, PPC won EUR 175 million in EU grants for Kotyli, Neo Syrakio

The partners manage their stakes through PPC Renewables and the RWE Renewables Europe and Australia branch.

As they reached their latest final investment decision, the companies pointed out that they secured EUR 175 million in grants for the twin projects from the European Union’s Recovery and Resilience Facility (RRF) and the National Recovery and Resilience Plan (NRRP) Greece 2.0.

They are financing the rest from own funds and with EUR 169 million from commercial banks, the announcement reads. Meton Energy has signed 10-year bilateral power purchase agreements (PPAs) with PPC and RWE Supply and Trading.

“With our latest investment decision, we underpin once again our strong commitment to the Greek market with now roughly 1.5 GW of solar capacity in deployment. This great achievement is the result of the excellent cooperation between the teams involved at RWE and PPC. Together we are accelerating the energy transition in Greece,” said Chief Executive Officer of RWE Renewables Europe and Australia Katja Wünschel.

Amynteo PV clusters coming online by year end

The two partners have so far energized five solar farms with 210 in total peak capacity. The construction of another PV plant with a peak of 105 MW is complete. Three more, of 625 MW in combined peak capacity, are planned to become operational by the end of 2025.

The nine units in three clusters have 940 MW altogether or 870 MW on the transmission grid, as alternating current. They are in the former Amynteo open cast lignite mine in Western Macedonia in the country’s north.

“We are delivering our solar projects at an impressive pace. The first cluster of the Amynteo portfolio is already energised, construction works for Amynteo clusters 2 and 3 are at an advanced stage and we are looking forward to connecting all projects to the grid this year,” said Costas Papamantellos, CEO of RWE Renewables Hellas and Meton Energy.

Turkey pushing against rivals for transmission of green electricity to EU

Turkey’s agreement with Azerbaijan, Georgia and Bulgaria on the transmission of renewable electricity could set back the project for an interconnector under the Black Sea between Georgia and Romania. In addition, President Recep Tayyip Erdoğan’s government fiercely opposes the Great Sea Interconnector project, part of the proposed Greece-Cyprus-Israel submarine link. Turkey is also pushing against rival hydrocarbon projects around Cyprus.

On the margins of the Southern Gas Corridor (SGC) annual meeting, a regional green energy project has come to the fore. Ministers of energy of Turkey, Bulgaria, Georgia and Azerbaijan, the host country, signed a memorandum of understanding on green electricity transmission and trade. The initiative envisages the establishment of a green energy corridor toward Europe.

The proposal for a power interconnections upgrade is an apparent competitor against a project by Romania, Georgia, Azerbaijan and Hungary. They plan to lay a high-voltage direct current (HVDC) cable under the Black Sea. Bulgaria does have a seat at the table, but even after several meetings it still hasn’t become a partner in the GECO submarine link project. The alternative onshore line through Turkey would give it a central role.

Bulgaria, which has been waiting to become a partner in the Black Sea submarine interconnection project, would get a central role in an onshore power transmission corridor that would go through Turkey

President Recep Tayyip Erdoğan’s government is determined to establish the key transmission and production hub for electricity and fossil fuels for the European Union. The new memorandum is another indicator, together with Turkey’s fierce opposition to the Great Sea Interconnector project, which is part of a proposed Greece-Cyprus-Israel submarine power link, and to hydrocarbon drilling around Cyprus.

Turkey also benefits from the TurkStream pipeline, which carries gas from Russia. It was built instead of the abandoned South Stream project, which was supposed to directly connect Russia and Bulgaria.

Studies to be commissioned by June

Turkish Minister of Energy and Natural Resources Alparslan Bayraktar said electricity from Azerbaijan and the region would reach his country via Georgia as well as Azerbaijan’s exclave of Nakhchivan. It means a line would go through Armenia.

The four energy ministers said a working group would complete the technical details and commission feasibility studies already by June.

Azerbaijani President Ilham Aliyev said his country would add 6.5 GW of renewable energy capacity by 2030, compared to the current 8 GW, from all sources. One of the biggest private investors is Abu Dhabi Future Energy Co. (Masdar).

TANAP’s capacity to be doubled

Turkey is diversifying its energy supply, Bayraktar noted. “Our natural gas imports from Turkmenistan, which started on March 1, are an important step towards the goal of securing our own supply while also carrying Central Asian energy to European markets,” he stated.

The minister highlighted the goal to increase the capacity of the Trans Anatolian Natural Gas Pipeline (TANAP), part of the Southern Gas Corridor, to 31 billion cubic meters per year from 16 billion.

Tensions rising as seabed survey for Great Sea Interconnector to resume

The NG Worker vessel is returning to carry out seabed surveys east of Greece’s Kasos-Karpathos island area, Energypress reported. The activity, part of the Great Sea Interconnector, was interrupted again in February after a Turkish corvette approached the ships NG Worker and Ievoli Relume.

After research was completed in the territorial waters of Greece and Cyprus, the last section is in international waters. Türkiye Gazetesi learned from security sources that Turkey wouldn’t allow “such a fait accompli.” The unnamed sources said the seabed survey is a breach of international law.

The power link project has also faced delays due to disputes around financing and it still risks losing a massive EU funding package. Turkey is promoting the idea of a cable connecting Cyprus to its own electricity transmission network instead.

Energy efficiency: the jack of all trades of EU electrification

By Arianna Vitali, Secretary General at the Coalition for Energy Savings, EUSEW’s partner organisation, highlighting the importance of energy efficiency in EU electrification, including cost savings, better grid flexibility, and protecting consumers.

It is no secret that for the EU to reach climate neutrality, the progressive electrification of our energy system will be essential – and with it, a sound strategy to achieve it in a cost-effective manner. With an Electrification Action Plan on the books for the new European Commission, it is crucial to ensure that the potential of energy efficiency to enable, accelerate, and lower the costs of EU electrification is not overlooked, but rather fully leveraged.

Energy efficiency and electrification: a match made in heaven

Shifting away from fossil fuels and towards renewable energy sources will require accelerating the electrification of both energy production and end-uses. While we all agree that electrification boosts energy efficiency, it is important to remember that this relationship is a two-way street where energy efficiency also has something to offer to the EU electrification process.

Indeed, by reducing overall energy demand, energy efficiency can ease grid congestion, reduce the costs of electrifying the EU energy system, and stabilise the prices paid by consumers. In that vein, the European Commission recently stressed that combined action on electrification and energy efficiency can reduce the EU’s fossil fuel import bill by €32.5 billion every year by 2030 (representing 25% of the total savings that would result from implementing the Action Plan). With the top priorities for this mandate focusing on improving competitiveness and affordability, leveraging the joint potential of energy efficiency and electrification is more relevant than ever.

Flexibility is key

A resilient energy system starts with a flexible energy system. Beyond supporting the EU’s climate neutrality goal, reducing energy demand through demand-side measures eases stress on the grid, allows for more flexible consumption patterns, and ultimately ensures a more adaptable and resilient energy system. The evidence is there: by adopting ambitious demand-side measures (both efficiency and flexibility), peak demand can be reduced by up to 39% in 2030 compared to a scenario without such improvements. This, by extension, lowers the need for additional infrastructure, making the overall electrification process faster and more manageable.

Lowering costs, boosting affordability, and protecting citizens

Energy efficiency’s potential to reduce infrastructure costs, and therefore overall system costs, is significant. For instance, ambitious demand-side measures respectively lower total energy system costs and reduce annual investments in distribution grids by around €40 billion.

These saved costs, which will ultimately not be paid by businesses and citizens, contribute to energy affordability by keeping electricity prices in check, helping European industries decarbonise while improving their competitiveness.

Finally, energy efficiency measures would also cut energy costs for households, helping to protect the most vulnerable. With ambitious demand-side measures, households could save significantly on their annual energy bills. Annual average household energy spending could go down to €900 by 2030, a considerable drop from today’s average of €1,190. This proves particularly useful for heating and road transport, which are expected to increase fossil fuel prices.

Time to put energy efficiency first

The EU transition towards decarbonisation and electrification of the energy system will require careful planning and substantial investment. Luckily, the EU has a jack of all trades on hand. With its wide range of benefits, from reducing infrastructure needs and costs, increasing energy security, cutting energy bills, and supporting both businesses and vulnerable citizens, energy efficiency offers readily available solutions to many of the challenges ahead and must be prioritised.

As stressed in the Action Plan for Affordable Energy, the EU needs a ‘decarbonised energy system, driven by a substantial scale-up of clean energy and electrification, with energy efficiency at its centre’. Prioritising the implementation of energy efficiency solutions on the ground will be key to building an affordable, secure, and competitive energy system for the future.

Romanian town Beiuș to boost geothermal distring heating to 100%

The local authority in Beiuș, a trailblazer in geothermal district heating in Romania, should apply for European funding to cover the entire area, according to a new study. The town already has the cheapest energy in the country.

Beiuș is the only town in Romania where geothermal energy accounts for more than 70% of the district heating of homes, institutions and firms. A new technical study is opening the way to a system upgrade by using European grants, state news agency Agerpres reported.

The project was funded by Innovation Norway, a state-owned development bank based in Oslo. Mayor of Beiuș Gabriel Popa said at a presentation marking its completion that his municipality aims to achieve 100% coverage. Iceland managed the endeavor and a company from the island country conducted the study on the geology of the local geothermal water reservoir.

The research covered possibilities to prevent losses in the geothermal district heating system. Beiuș, in Bihor county in northwestern Romania, has just under 10,000 inhabitants.

According to the authors, European development programs are accessible. A new guide is under public consultation.

Dozens of local authorities including capital Bucharest are developing geothermal heating projects.

EEA funding available to get full coverage

The speakers at the conference presented prospects for development using subsidies from the European Economic Area (EEA). The region consists of European Union member states and Iceland, Liechtenstein and Norway.

Engineer Horia Ban said heat pumps could save 30% to 50% of the energy of the water returned from the geothermal district heating system. He is the head of the Oradea-based SRG association, which promotes heat pump solutions for geothermal heating, ventilation and air conditioning (HVAC), and of local renewable energy company Termoline.

The European Commission and European Geothermal Energy Council (EGEC) funded complementary research into air conditioning from geothermal wastewater.

Agriculture can tap water from geothermal district heating system in Beiuș

To lower the losses, the study’s authors recommend insulated PE-Xa pipes and directing the exit flow from the geothermal district heating system to greenhouses, wood dryers and fish farms.

Transgex, based in the county’s capital Oradea, supplies the geothermal water in Beiuș. The reservoir was discovered in 1996 at a depth of 2.6 kilometers. The temperature is 85 degrees Celsius.

The prefeasibility study was funded in 2017 in partnership with Iceland, through EEA Grants. Beiuș is now a town with the cheapest energy in Romania, the article adds.

An EU project worth EUR 33.6 million began a year ago for the construction of an aquapark. It envisages a facility with eight outdoor pools of 6,691 square meters overall in Beiuș. The grant amounts to EUR 12.5 million.

Looking at entire Southeastern Europe, Turkey sticks out as one of the main global players in geothermal energy including power plants, a more complex technology. The potential in Romania and Greece is among the highest in the EU. Bulgaria is also working with EEA funds. Serbia only has small projects for now.

Croatia hosts one geothermal power plant, though is currently offline due to an ownership dispute. Numerous municipal and private projects are underway.
