RE-Source Southeast is back for its 6th edition, bringing together the region’s leading actors in corporate renewable energy sourcing. The event convenes industrial and corporate energy consumers, project developers, electricity traders, and renewable power producers to examine how the market is evolving and where new opportunities are emerging.
Southeast Europe is entering a decisive new phase. A rapidly expanding pipeline of renewable generation, alongside more than 12 GWh of new battery energy storage (BESS) capacity expected by 2026, is reshaping how power is produced, traded, and consumed. In this changing landscape, hybrid PPAs are opening new pathways for developers, traders, and offtakers—transforming risk management, flexibility and value creation across the market.
On 27-28 May 2026, 450+ participants from over 20 countries will gather in Sofia to share practical insights and real-world experience in corporate renewable sourcing, with a strong focus on Romania, Greece, and Bulgaria.
Networking remains at the core of the RE-Source Southeast experience. The event is designed to foster meaningful conversations—connecting senior decision-makers, industry leaders, and future partners, while creating space to exchange ideas and learn from those shaping the region’s energy transition.
RE-Source SEE will be accompanied by a RES plus BESS exhibition, dedicated to renewable energy generation and battery storage solutions. The exhibition and conference will bring together leading technology providers, industry experts, and energy stakeholders to showcase cutting-edge solutions shaping the future of sustainable power.
RE-Source Southeast Conference and Exhibition is where the region’s renewable energy community meets to connect, learn, and move the market forward.
Event Agenda
6th Annual Forum for Renewable Energy Corporate Sourcing & Investment in Southeast Europe
27–28 May 2026 · Sofia Tech Park, Sofia, Bulgaria
Opening of the RES + BESS Technology Exhibition
Delegates are invited to register, collect conference materials, and explore the Technology Showcase Area featuring the latest solutions in solar, wind, and battery storage.
The session will centre on the presentation of the report Scaling Up Electricity System Flexibility in Bulgaria Through Digital Solutions, which examines the current state and potential of digital technologies to enhance system flexibility, and identifies the regulatory, technological, and market conditions needed to accelerate the transition. The report serves as the structured basis for practitioner dialogue.
Workshop for Corporate Energy Buyers
Working session for corporate energy buyers and offtakers. Participants will gain a structured overview of the SEE renewable energy procurement landscape, PPA mechanics, and BESS-augmented offtake options. Facilitated by leading legal, financial, and advisory experts.
This session brings together innovative startups and scale-ups alongside corporates and investors exploring sector coupling opportunities.
Welcome Address
Get up to date on the evolving Power Purchase Agreement landscape in Europe. Leading PPA experts will present the latest market data, discuss key regulatory shifts, and unpack the changing dynamics between buyers and sellers. Which regulatory and market factors will shape PPAs in the coming years — and how is battery storage beginning to redefine what a PPA can look like?
What’s next for utility-scale wind, solar and storage in Southeast Europe? This panel presents the latest market developments across Bulgaria, Greece, Romania, and the wider SEE region. Speakers will address the hard realities — zero prices, grid saturation, curtailment risk — while addressing the transformative role of large-scale battery storage for unlocking the next phase of RES growth.
Battery storage is reshaping how renewable energy is developed, traded, and consumed. This panel goes beyond the hype to examine real-world corporate strategies — business models, commercial strategies, technical and regulatory challenges on the road to a more flexible regional power system.
As low and negative prices proliferate and tighten merchant margins, the market is innovating rapidly. This session examines offtake strategies and structures aimed at hedging against capture price erosion — as well as other risk-optimisation strategies available to developers, traders and corporate buyers navigating a volatile electricity market.
Access to capital remains the critical enabler — and constraint — for scaling renewable energy and storage in the region. Panellists from development finance, commercial banking, and the legal and advisory sectors will examine current deal structures, risk appetite, and the evolving role of blended finance, green bonds, and DFI instruments in the SEE market.
Southeast Europe is at a crossroads. Unprecedented renewable capacity additions have collided head-on with grid infrastructure bottlenecks, slow interconnection processes, and limited flexibility resources. This panel separates reality from rhetoric: how can the region overcome its infrastructure constraints — through flexibility markets, demand response, and smart grid investment — to remain a credible destination for green capital?
Wind Case Study Bulgaria – “Navigating the New Frontier: Overcoming Barriers to Deliver Bulgaria’s First Modern Wind Farm
The competitive frontier in SEE is shifting from megawatts built to megawatts optimised. This forward-looking panel explores how digital platforms, algorithmic trading, and AI-driven energy management are redefining value creation for generators, aggregators, and consumers — and what this means for the market architecture of tomorrow.
Decarbonisation commitments are under pressure across Europe due to rising energy costs and geopolitical volatility. For energy-intensive industries in SEE, the question is not simply how to decarbonise, but how to do so while remaining competitive. This panel brings together industrial offtakers, policy experts, and energy strategists to examine how companies in the region are recalibrating their decarbonisation roadmaps and how the EU’s energy security agenda is reshaping investment decisions.
