While only a few years ago the industry was primarily discussing the prospects of storage technologies, today it is already possible to talk about concrete projects and accumulated practical experience.<\/span><\/p>\n<blockquote><p><span style=\"font-weight: 400;\">\u201cA few years ago, we spoke about energy storage systems as the future of the power system. Today, we are already discussing the path that has been completed. The year <\/span><b>2025 can confidently be called the year of energy storage development in Ukraine<\/b><span style=\"font-weight: 400;\">, when the first significant volumes of such projects were integrated into the power system\u201d, noted Vitalii Nykolaienko.<\/span><\/p><\/blockquote>\n<p><span style=\"font-weight: 400;\">According to him, the market\u2019s activation has been driven by several key factors: the declining cost of battery technologies, the emergence of economically viable financial models, and the gradual formation of the regulatory framework.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Among the key applications of energy storage systems currently developing in Ukraine, the expert highlighted:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">participation in <\/span><b>ancillary services markets<\/b><b><br \/>\n<\/b><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>energy arbitrage<\/b><span style=\"font-weight: 400;\"> on the electricity market<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>industrial storage systems for self-consumption<\/b><span style=\"font-weight: 400;\"> by enterprises<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>integration of BESS with solar power plants<\/b><b><br \/>\n<\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">According to <\/span><b>VOLTAGE Group<\/b><span style=\"font-weight: 400;\">, the company\u2019s project portfolio already includes <\/span><b>dozens of megawatts of energy storage capacity<\/b><span style=\"font-weight: 400;\">, including both standalone storage projects and hybrid solutions combined with solar generation.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">During the presentation, several implemented projects were showcased, including facilities providing ancillary services and industrial storage systems designed to meet the internal energy needs of enterprises.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">One example is a project implemented for the <\/span><b>agro-industrial holding MHP<\/b><span style=\"font-weight: 400;\">: an energy storage system with a capacity of <\/span><b>2 MW and an energy capacity of 4 MWh<\/b><span style=\"font-weight: 400;\">, integrated with solar power plants at the company\u2019s production facilities.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Within this model, excess solar generation is stored in the energy storage system and used during evening hours when electricity prices on the market increase. This approach helps improve the economic efficiency of investments in renewable generation.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Special attention during the meeting was also given to <\/span><b>typical mistakes that can significantly affect project implementation<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">According to the speaker, investors often underestimate the importance of <\/span><b>grid connection<\/b><span style=\"font-weight: 400;\">, focusing mainly on the cost of the core equipment.<\/span><\/p>\n<blockquote><p><span style=\"font-weight: 400;\">\u201cVery often we see situations where an ESS or solar power plant is already installed, but the facility cannot operate because the external grid infrastructure is not ready. We call it a <\/span><b>\u2018Ferrari without a road\u2019<\/b><span style=\"font-weight: 400;\">: the equipment exists, but it cannot deliver any value\u201d, emphasized Vitalii Nykolaienko.<\/span><\/p><\/blockquote>\n<p><span style=\"font-weight: 400;\">According to him, engineering mistakes or underestimation of grid infrastructure can lead to significant delays in commissioning projects and the loss of expected revenues.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The expert also warned against the common practice of purchasing equipment <\/span><b>before the completion of technical project design<\/b><span style=\"font-weight: 400;\">, which can result in incompatibility between components or the need to change the project concept after investments have already been made.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">During the discussion, participants also addressed the growing trend of <\/span><b>integrating energy storage systems with new solar power plants<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">According to Vitalii Nykolaienko, today <\/span><b>almost all new solar projects are being considered by investors together with energy storage systems<\/b><span style=\"font-weight: 400;\">, as this allows optimization of generation economics and more efficient participation in the electricity market.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Participants also discussed technical requirements for equipment, the importance of using solutions from reliable manufacturers, and issues related to integrating energy storage systems into Ukraine\u2019s power system.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The event concluded with an active <\/span><b>Q&amp;A session<\/b><span style=\"font-weight: 400;\">, during which participants discussed technical, economic, and regulatory aspects of implementing energy storage systems in Ukraine.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Summarizing the meeting, participants emphasized that <\/span><b>sharing practical experience in the implementation of BESS projects is critically important for the development of this segment of the energy sector in Ukraine<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The <\/span><b>Solar Energy Association of Ukraine<\/b><span style=\"font-weight: 400;\"> continues to facilitate expert discussions and experience exchange among market participants, contributing to the development of <\/span><b>solar generation and energy storage systems in Ukraine<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Please note that <\/span><b>recordings of all SEAU meetings and webinars are available to SEAU members upon request<\/b><span style=\"font-weight: 400;\">.
