On September 3, 2025, the industry forum "Charge and Earn: How Energy Storage Systems Unlock New Opportunities in the Electricity Market" will take place in Kyiv, organized by the Solar Energy Association of Ukraine in partnership with JSC "Market Operator."

The forum will serve as a platform to discuss the prospects of Energy Storage Systems (ESS) in Ukraine, which are a key trend in the energy sector. The focus will be on the arbitrage model of ESS operations on the Day-Ahead Market (DAM), investment payback, practical cases, and techno-economic assessments.

Forum Program Highlights:

• How ESS enables buying electricity at low prices and selling it during peak hours;
• How businesses integrate storage systems into their models (case studies from Ukrainian companies);
• Challenges and opportunities for investors;
• The role of forecasting and balancing;
• The potential of ESS participation across all market segments: DAM, Intraday Market (IDM), balancing market, and ancillary services market.

A separate Q&A session will allow registered participants to submit their questions prior to the event — the most relevant ones will be addressed during the third panel in an open discussion format.

Why is energy storage not just a temporary trend?

With the growing share of renewable energy sources and an unstable consumption schedule, the flexibility of the energy system becomes critically important. ESS — battery systems or other storage technologies — provide this flexibility by enabling:

• load reduction on the grid,
• price arbitrage operations,
• improved reliability of energy supply,
• operation within "smart" grid formats.

In the coming years, the role of storage systems will only increase, as they will become the foundation for a decentralized, sustainable, and efficient energy system. Therefore, this forum is for businesses that aim to stay ahead, scale in line with global trends, and develop new revenue sources in the energy sector.

Registration for the forum is available at: https://bess.aseu.solar. The venue will be communicated personally to each registered participant for security reasons.

JSC "Market Operator" has prepared an analytical work "The potential of Energy Storage System (ESS) on the Electricity Market: Advantages of Spot Arbitrage", dedicated to a topic of growing relevance - the use of Energy Storage System (ESS) for electricity trading on the spot market.

In a world moving toward decentralized energy and an increasing share of renewable energy sources, the role of ESS becomes critically important — particularly for balancing supply and demand, enhancing the flexibility of the power system.

What’s the essence?

High price volatility in the electricity market, especially in the Day-Ahead Market (DAM), creates favorable conditions for price arbitrage — purchasing electricity during low-demand hours and selling it during peak periods. This strategy enables ESS operators to generate profit and accelerate the return on investment in this innovative field.

In this analytical report, JSC "Market Operator" has:

• Analyzed the arbitrage model of ESS operations on the DAM as one of the key profit-generating approaches
• Described the main features of all segments of Ukraine’s electricity market (bilateral contracts market, day-ahead market, intraday market, balancing market, ancillary services market)
• Performed investment payback calculations considering service costs and ESS capacity
• Presented DAM operation scenarios based on historical price data
• Provided detailed source data and methodology, allowing independent assessment of a project's investment attractiveness
• Outlined input data and specific steps of the calculation algorithm to evaluate potential profit and investment metrics of the project.

This report will be useful for:

• Producers planning to invest in ESS
• Investors in the renewable energy sector
• Electricity traders and market participants
• Aggregators
• Energy analysts and government institutions

Energy storage systems are not just a trend — they represent a real opportunity to establish a new, stable business segment in the Ukrainian energy market. That is why JSC "Market Operator" continues to expand the range of analytical publications, helping the market to develop strategically and reasonably.
