During the second “Bankable” panel titled “How to Finance, Legalize, and Technologically Implement BESS” at the Forum “Energy of Freedom: Resilience and New Opportunities for the Energy Storage Systems Market in Ukraine,” Yevhen Miachyn, Director of the Corporate Business Development & Support Department of Oschadbank, presented the real contribution of the banking sector to the development of the country’s new energy sector.

His speech was one of the most data-rich, filled with market conclusions and practical recommendations for investors.

50% of Energy Projects Realized Thanks to Bank Financing

Yevhen Miachyn began his speech with key statistical data on the role of banks in the development of distributed generation. According to government officials, 1.8 GW of distributed generation has been commissioned in Ukraine recently, and according to the National Bank, a significant part of these capacities—1.2 GW—was financed by banks under the energy memorandum.

“This means that at least 50% of all implemented energy projects were launched specifically thanks to bank financing,” he emphasized.

434 MW of BESS Financed by Banks, with Over 200 MW by Oschadbank

According to a survey of banks conducted by the National Bank of Ukraine, 434 MW of energy storage systems (BESS) have been implemented and financed by financial institutions over the last year and a half.

Oschadbank is the leader in this direction: over 50% of this capacity—more than 200 MW—was financed specifically by the bank, and these projects have already been put into operation.

In the structure of energy projects implemented by corporate business clients of Oschadbank, the energy storage sector occupies a dominant share:

  • 60% — BESS projects,
  • 40% — Solar Power Plants (SPP) combined with BESS, wind power plants, and gas piston generation.

A 330 MW Pipeline and Consistently High Client Demand

Demand for BESS from corporate clients continues to grow. Yevhen Miachyn reported that Oschadbank’s portfolio of potential projects stands at 330 MW, and of these, similar to realized cases, approximately 60% account for energy storage systems.

“We are learning together with our clients because some of the projects we implement are new to the market. We accept risks together, using various instruments and financial products,” noted the Director of the Corporate Business Development & Support Department of Oschadbank.

First BESS Projects in Ukraine on the Ancillary Services Market: 220 MW

2025 became a turning point for the energy storage market—it was this year that large-scale BESS projects were first implemented:

  • KNESS — 40 MW,
  • DTEK — 180 MW.

Together, this is 220 MW already operating on the ancillary services market. Oschadbank was the main financial partner in these projects.

Energy Arbitrage: The Next Stage of BESS Development

Yevhen Miachyn emphasized that alongside projects for the ancillary services market, the bank is already processing projects that will operate on energy arbitrage. Although there are no signed agreements yet, Oschadbank, together with clients, is analyzing financial models and key market assumptions, assessing risks, and preparing for financing.

What Defines the Success of a BESS Project

The Director of the Corporate Business Development & Support Department of Oschadbank outlined two primary factors that shape the viability and attractiveness of a project:

1. A High-Quality Financial Model

Oschadbank, having extensive experience with realized BESS projects, helps the client pay attention to key factors when preparing the financial model, taking market specifics into account.

2. A Strong Team

The client’s management and project team, their activity, professionalism, and effective interaction with the bank directly determine the result.

Payback Period of BESS Projects: Real Timeframes

Yevhen Miachyn voiced specific figures:

  • BESS on the ancillary services market — 5–7 years payback.
  • BESS for arbitrage — 6–8 years.

These terms remain realistic even considering war, technological, and regulatory risks.

Investors Are Actively Entering BESS Despite Risks

Despite martial law and the unpredictability of the regulatory field, investor interest—including foreign investors—is not waning. And they are turning specifically to bank financing, which confirms trust in the banking system and the prospects of the technology.

Instruments That Make Financing More Accessible

Yevhen Miachyn separately highlighted the opportunities investors have today:

  • state preferential lending programs,
  • portfolio guarantees,
  • grant assistance from international partners,
  • risk-sharing instruments.

All this allows banks to reduce risks and make financing more accessible.

“Today, if there are ideas and projects, investors have every opportunity to realize them and receive support. And we, for our part, are ready to enter projects that do not yet have established experience in the market,” summarized Yevhen Miachyn.

His speech confirmed: the banking system is one of the main driving forces in the development of the BESS market and the strengthening of Ukraine’s energy independence.
