The Solar Energy Association of Ukraine estimates the country added 1.6–1.9 GWh of energy storage in the first half of 2026 and projects about 3.2 GWh for the full year. The preliminary figures come as Ukraine seeks to restore damaged power capacity and expand distributed energy resources, but the association says security, financing and grid access will affect deployment.
Ukraine added an estimated 1.6–1.9 GWh of energy storage in the first half of 2026, according to preliminary assessments by the Solar Energy Association of Ukraine (SEAU). The association’s indicative forecast is about 3.2 GWh for the full year, though it says security, financing and grid connections could affect deployment.
SEAU’s assessment puts first-half storage additions within a range rather than at a single confirmed total. The figures are estimates, and the source report does not provide a breakdown of installed storage by project size, technology or market segment. SEAU Chairman of the Board Vladyslav Sokolovskyi told pv magazine that the 2025 storage figure included several segments, among them portable battery systems commonly used for backup power.
The association also estimated that Ukraine added as much as 1.1 GW of solar capacity in the first half, bringing installed solar capacity to between 9.4 GW and 9.7 GW by midyear. SEAU expects solar additions to reach around 2 GW in 2026, compared with approximately 800 MW in 2024 and 1.5 GW in 2025. It expects installations up to 1 MW, mainly intended for self-consumption, to make up around 80% of new solar installations by number in 2026—not by capacity.
SEAU’s storage outlook follows an estimated 2.9 GWh added in 2025. The association’s market data placed Ukraine fourth among European battery storage markets that year. The first-half 2026 estimate and the full-year projection cover a market with different types of systems, so the headline capacity figure should not be read as a count of utility-scale installations alone.
Storage and Ukraine’s Power Resilience
Storage can supply electricity during interruptions and help users make more use of locally generated solar power. Sokolovskyi said batteries provide backup for households and businesses, and that the financial value to businesses can include losses avoided when essential operations continue. He also pointed to lower equipment costs as a factor making solar-plus-storage systems more accessible.
The development matters against a power-system backdrop that SEAU describes as shaped by damage to energy infrastructure, generation shortages and recurring outages. Sokolovskyi said Ukrainian energy experts estimate the system needs around 10 GW of new and restored generation capacity across technologies. He also said network damage and shortages have contributed to increased reliance on electricity imports from neighbouring EU countries. Those statements describe the association’s assessment; the source report does not provide an independently verified capacity tally or import data.
Distributed systems and batteries can support supply closer to consumers and help critical facilities operate when external power is interrupted. They do not, by themselves, replace the need to restore large-scale generation and electricity networks. SEAU’s outlook is a measure of expected deployment, while the practical effect on reliability will depend on where systems are installed, how they connect and whether they can operate during outages.
From 2025 Growth to 2026 Plans
Ukraine’s storage market recorded an estimated 2.9 GWh of additions in 2025, according to market data supplied by SEAU. Sokolovskyi cautioned that the figure covered multiple market segments, including portable batteries. This matters when comparing annual capacity estimates: the reported total is not limited to grid-scale projects.
SEAU says this year’s solar growth is expected to include many small installations designed primarily for self-consumption. Its estimate that projects up to 1 MW could represent about 80% of new installations is based on the number of installations, not their combined capacity. The association links the wider growth of distributed generation and storage to both longer-term energy development and the immediate challenge of supplying businesses, households and critical infrastructure during wartime.
The policy and market calendar also includes changes to solar feed-in tariffs earlier in 2026 and the introduction of time windows for eligibility, according to the source report. Later in the week after the report’s publication, state-owned JSC Guaranteed Buyer was scheduled to run two solar auctions offering a combined 150 MW. These measures and auctions concern solar market development; the source does not say they directly account for the storage additions reported for H1.
““Our 2026 outlook for both solar and storage remains conditional on security, access to financing and grid connections.””

Forecasts Depend on Security and Access
The 1.6–1.9 GWh figure is a preliminary estimate, and SEAU’s roughly 3.2 GWh full-year outlook is indicative rather than a confirmed outcome. The source report does not detail how the estimate was compiled or give a segment-by-segment accounting of the first-half additions.
SEAU says security conditions, access to financing and grid connections will shape both solar and storage deployment. It also says forecasting through the end of 2027 is particularly difficult. The report does not specify how much capacity has been installed and commissioned versus announced or under construction, nor how much of the reported storage is portable, behind the meter or connected to the grid.
Auctions and Further Deployment
SEAU’s next reported marker is the full-year 2026 deployment: whether storage additions approach its indicative 3.2 GWh forecast, and solar additions reach around 2 GW. The association says its outlook remains subject to security, financing and grid connection conditions, so later figures may differ from the preliminary estimate.
In the near term, JSC Guaranteed Buyer was scheduled to hold two solar auctions later in the week after the September 28 report, offering a combined 150 MW. The source does not give auction results. SEAU has also called for faster infrastructure restoration and protection, continued distributed generation support, insurance and guarantees for war-related investment risks, simpler grid connections, closer EU market integration, concessional financing and microgrids combining solar and storage with other sources where needed.
Key Questions
How much energy storage did Ukraine add in the first half of 2026?
SEAU’s preliminary estimate is 1.6–1.9 GWh. The report does not give a final audited total.
How much storage does SEAU expect Ukraine to add in 2026?
SEAU’s indicative full-year outlook is around 3.2 GWh. The association says security, financing and grid connections could affect deployment.
Does the storage figure cover only large battery projects?
No such limitation is stated. Sokolovskyi said the 2025 market figure covered multiple segments, including portable battery systems used for backup. The report does not break down H1 2026 additions by segment.
What else did Ukraine add in the first half of 2026?
SEAU estimated up to 1.1 GW of new solar capacity during H1, bringing total installed solar capacity to an estimated 9.4–9.7 GW by midyear.
What could affect further storage and solar growth?
SEAU identifies security, financing and grid connections as conditions affecting its outlook. It also says forecasting deployment through the end of 2027 is particularly difficult.
