Energy transition creates market opportunities for battery storage

In Lithuania, FENECON GmbH recently showcased the potential of German storage technology as part of the Renewable-Energy-Solutions Programme. With increasing electrification across all sectors, the decentralisation of power generation, and the growing share of renewables, electricity grids face significant challenges. A successful transition to a sustainable energy system requires technologies that can balance fluctuations between supply and demand.

Battery storage is therefore indispensable. It strengthens supply security and energy independence, optimises self-consumption of renewable energy, and enables profitable energy trading. Combined with smart energy management systems (EMS), storage supports the integration of EV charging infrastructure, the implementation of dynamic tariffs, and intelligent sector coupling. For households, businesses, and industry alike, battery storage is becoming essential.

Energy security in the baltics

The importance of reliable energy supply is particularly evident in Lithuania, where geopolitics play a decisive role. Since joining the EU in 2004, Estonia, Latvia, and Lithuania have sought to disconnect from the Russian-dominated BRELL grid and synchronise with the European network. Russia’s invasion of Ukraine in 2022 significantly accelerated this process.

On 9 February 2025, the Baltic states successfully synchronised with the European power grid. This milestone was accompanied by EU-supported infrastructure projects, including interconnections with Finland, Poland, and Sweden, upgrades to substations, and the development of four large-scale battery storage facilities with a total capacity of 200 MW. Lithuania has also set ambitious targets: by 2028, the country aims to install 1.7 GW / 4 GWh of additional storage capacity to further strengthen flexibility and reliability.

German quality contributes to Lithuanian energy security

Recognising this growing market, FENECON GmbH was selected for the RES Programme of the German Energy Solutions Initiative. The Bavarian company contributes to Lithuania’s energy security with EMS solutions developed and manufactured in Germany, ensuring the highest standards in both energy and data security.

FENECON benefits from its partnership with the Lithuanian high-tech group Elinta, UAB, a specialist in industrial automation, electronics, and smart systems. Acting as FENECON’s installation and service partner, Elinta set up the first reference plant at its Kaunas production site: a 20 kW / 28 kWh storage system.

Commissioned in summer 2025, the installation increases Elinta’s energy independence in combination with its existing PV plant. It serves as a backup power source, supports grid services, and optimises EV charging through Elinta Charge stations – part of Elinta Group’s electromobility business.

Elinta CEO Vytautas Jokužis highlighted the strategic importance of the partnership:

“We were very deliberate when choosing a partner in this technology space. Just like with EV charging, where Elinta started long before the market had taken off, Fenecon invested early in the most crucial component – the FEMS – and established a clear lead. We are very happy to have such a strong partner at our side and look forward to building synergies across the Baltics.”

At the inauguration, he added:

“We really appreciate working with a German company. The quality of their products is significantly better than what competitors offer. Even though this is only the beginning of our cooperation, we see great opportunities to deepen collaboration, including in joint R&D. Fenecon’s technology contributes to grid stability, promotes the integration of renewables, and strengthens energy independence.”

Local benefits and perspectives

The Lithuanian perspective on battery storage was emphasised by Akvilė Eglinskaitė of the Research Council of Lithuania:

“Lithuania’s energy system faces several challenges: the intermittency of solar and wind power, grid balancing, dependence on imports, ageing infrastructure, strong price fluctuations, and the need for fast reserves. Battery storage helps address all of these. We already see the benefits in the first large battery parks near Šiauliai and Alytus, which stabilise the grid and reduce the need for costly backup power.”

She underlined the direct benefits for businesses and citizens:

“Companies with solar panels can now use more of their own green energy and save on bills, while people benefit from more stable prices and fewer disruptions.”

Looking ahead, she added:

“Fenecon brings not only the hardware but also smart control systems and valuable know-how with European regulation. This helps Lithuania avoid ‘trial and error’ and accelerate progress. I hope these technology and knowledge exchanges will also enable us to develop new products in the future and make use of EU Horizon programmes for innovation.”

Outlook

On 25 September 2025, the Kaunas reference plant was officially inaugurated during a high-level ceremony attended by representatives of the German Embassy, the German-Baltic Chamber of Commerce (AHK), dena, and FENECON. Local stakeholders had the opportunity to experience German technology first-hand.

The sale of additional storage facilities is currently under negotiation. FENECON has announced that further reference plants are to be installed and commissioned in the fourth quarter of 2025 and in 2026. Collaboration with Elinta is also being intensified: training for the local partner on the operation and maintenance of the systems took place after the inauguration in order to ensure a sustainable market entry. This means that follow-up orders can be handled directly by Elinta.

About the RES Programme

With the RES programme, the German Energy Solutions Initiative of the Federal Ministry of Economical Affairs and Energy supports German companies in the renewable energy and energy efficiency sectors enter new markets. Within the framework of the programme, reference plants are installed and marketed with the support of the German Energy Agency (dena). Information and training activities help ensure a sustainable market entry and demonstrate the quality of climate-friendly technologies made in Germany.”
