3rd Conference on Advancing Renewable Investments – guarantees of origin could drive Europe’s green energy integration

As CBAM nears implementation, the Ljubljana conference highlighted market tools and partnerships to accelerate clean energy integration with the European Union, the Energy Community Secretariat said. It pointed out that as more renewables capacity is connected to the grid, storage and flexibility solutions would become increasingly vital to enable the sector’s continued growth and integration.

The rollout of national electronic registries for guarantees of origin was recognized as essential to verifying the low-carbon value of regional electricity exports and advancing market-based integration with the EU.

Ministers, regulators, investors, and private sector representatives from across South East and Eastern Europe gathered in Ljubljana for the 3rd Conference on Advancing Renewable Investments, hosted by the Energy Community Secretariat and the Government of Slovenia, to boost renewable investment and advance the region’s shift toward clean, interconnected energy systems.

“Energy Community contracting parties are advancing accelerated integration with the EU’s electricity market – a process that, thanks to the Energy Community framework, with market coupling nearing completion, can be achieved even ahead of full EU membership. Expanding renewables is central to this effort, enabling countries to align with EU policy targets and speed up decarbonisation,” the update reads.

Integration with the EU’s electricity market can be achieved ahead of full membership

The results are tangible, according to the Energy Community Secretariat’s 2025 CBAM Readiness Tracker. Renewable energy excluding large hydropower has increased by more than 50% since 2020 – reaching 5.1 GW, fuelled largely by governmental support schemes.

While it is a notable success, continued progress will depend on the contracting parties’ ability to build on this momentum and mobilize efforts beyond government support to fully meet the ambitious 2030 targets set out in their national energy and climate plans (NECPs) and achieve carbon neutrality by 2050. As more renewables capacity is connected to the grid, storage and flexibility solutions will become increasingly vital to enable the sector’s continued growth and integration, the organizers said.

Uncertanties emerging ahead of CBAM charge introduction

At the same time, as the definitive phase of the EU’s Carbon Border Adjustment Mechanism (CBAM) begins on January 1, uncertainties are emerging for renewable energy investors, the secretariat stressed.

Discussions at the conference highlighted stakeholders’ expectations for the European Commission to clarify CBAM implementation rules, while continuing to rely on the secretariat to raise concerns about potential risks to renewable energy investments arising from unintended CBAM impacts.

As a no-regret pathway, participants discussed measures to accelerate the shift toward market-driven renewable investments, strengthening the sector’s credibility and long-term financial stability. A matchmaking dialogue brought together renewables producers and corporate buyers, reflecting growing private-sector interest in long-term power purchase agreements (PPAs) to boost investment and market confidence.

Lorkowski: GOs turn transparency into trust, trust into investment

Finally, the rollout of national electronic registries for guarantees of origin (GOs) was recognized as essential to verifying the low-carbon value of regional electricity exports and advancing market-based integration with the EU.

“Guarantees of origin are the compass guiding Energy Community markets toward the EU’s clean energy future. They turn transparency into trust, and trust into investment, enabling regional producers to access new markets, attract financing, and build confidence in the energy transition,” said Energy Community Secretariat Director Artur Lorkowski.

Ongoing efforts to establish a mutual recognition framework with the EU are underway, in close coordination with the European Commission and the Association of Issuing Bodies (AIB), to enable cross-border trade in renewable electricity.
