On October 9th in Vienna, the Energy Club forum “Balancing Europe’s Energy System: Challenges, Solutions, and Prospects” was held, gathering leading experts, regulators, investors, and technological innovators.
The forum became a brainstorming session on the main issue of modern energy—how to ensure the stability and security of power grids in a new reality where the growing share of RES (renewable energy sources) creates unprecedented challenges. The European energy system is undergoing its greatest transformation in a century: the rapid expansion of “green” generation is reducing grid inertia, increasing the risks of generation fluctuations, and making large-scale blackouts a real possibility. That is why the issue of balancing has become key in market development strategies.
ETG: From Electricity Supplier to Innovative Energy Storage Manufacturer
Volodymyr Shvedkyi, Member of the Board of Directors of Energy Trade Group (ETG), spoke at the panel discussion “The Future of Balancing: Digitalization, Flexibility Markets, and Consumer Integration”. He shared the experience of ETG—a Ukrainian energy company with over a 10-year history, supplying electricity and gas to more than 5,000 small and medium-sized enterprises throughout Ukraine.
In recent years, the company has significantly expanded its business portfolio—investing in renewable generation, entering the top 20 largest players in Ukraine’s alternative energy sector (Forbes 2024 ranking), and launching its own production of energy storage systems (ESS). Despite the full-scale war, ETG opened the first engineering center in Ukraine dedicated to developing unique solutions for energy storage. In 2024, the company introduced its own ESS brand, “Revention,” launching a full production cycle—from design development to commercial manufacturing.
“Revention”: A Ukrainian Brand Already Operating in Critical Infrastructure
To date, ETG has installed over 1,000 small energy storage systems (total capacity of about 25 MWh) and over 150 medium-sized systems. These solutions are already functioning at public sector facilities, in banks, hospitals, educational institutions, and small businesses—from coffee shops to social institutions in frontline territories. The “Revention Power Cube” systems have a capacity of 7 to 72 kW and can provide energy autonomy in crisis conditions.
All devices operate under centralized dispatch control via a proprietary SCADA system, which meets cybersecurity requirements and allows for real-time monitoring of each storage unit’s operation. An R&D (Research & Development) department was specifically created within ETG to develop the ESS direction, focusing on engineering innovations and proprietary software development to optimize the use of energy storage.
Ukraine as an Example of Resilience: “We lost 50% of our energy system—and we are still operating”
Volodymyr Shvedkyi emphasized that despite colossal losses from Russian aggression, the Ukrainian energy system remains reliable. “Since synchronization with ENTSO-E in 2022, Ukraine has proven it can be a stable partner in the European energy community, even in times of war,” he stressed.
According to ETG estimates, the potential of the Ukrainian market for installing storage systems is:
These figures demonstrate the huge development potential for local and medium-sized energy storage, which can support system balancing while also becoming a source of income.”Balancing Assets are Not Reserves, but Sources of Income”.
Concluding his speech, Volodymyr Shvedkyi emphasized: “Flexibility is the true currency of the modern energy market. Those who can control energy flows determine its value. Balancing assets are not reserves; they are a new source of income. Ukraine has all the prerequisites to become part of a stable European energy system”.
The company is actively preparing to expand its presence in the household market once this segment is open to competition. ETG’s strategic goal is a 100% “green” supply portfolio, decarbonization, and support for the sustainable development of the Ukrainian economy.
