Ukraine added an estimated 1.6–1.9 GWh of energy storage in the first half of 2026, according to preliminary figures from the Solar Energy Association of Ukraine. The association’s indicative full-year outlook is about 3.2 GWh, but it says deployment depends on security, financing and grid connections.
Ukraine added an estimated 1.6–1.9 GWh of energy storage in the first half of 2026, according to a preliminary assessment by the Solar Energy Association of Ukraine (SEAU). The association’s indicative forecast puts additions for the full year at about 3.2 GWh, a pace that could expand backup power options as the country faces wartime damage and electricity supply interruptions.
The H1 estimate is a range rather than a final verified total. SEAU’s preliminary figures, reported by pv magazine, place new storage capacity between 1.6 GWh and 1.9 GWh. The association expects around 3.2 GWh for 2026, but its chairman, Vladyslav Sokolovskyi, said that outlook depends on security conditions, access to financing and grid connections. The report does not provide a breakdown of H1 additions by project size or market segment.
SEAU also estimated that Ukraine added as much as 1.1 GW of solar capacity in the first half of the year, bringing total installed solar capacity to an estimated 9.4–9.7 GW by midyear. It expects solar additions to reach around 2 GW for 2026. The association attributed much of the expected growth to smaller projects: installations of up to 1 MW, mainly intended for self-consumption, could account for about 80% of new installations by number. That figure refers to the number of projects, not their share of added capacity.
SEAU’s market data puts battery storage additions in 2025 at 2.9 GWh, making Ukraine the fourth-largest European market that year, according to the association. Sokolovskyi said the total spans several market segments, including portable battery systems used for backup power. The 2025 figure therefore covers a broad range of systems and should not be read as a count of utility-scale installations alone.
Storage for a Damaged Power System
The reported additions matter because storage can supply electricity when other sources are unavailable and help users make greater use of locally generated solar power. SEAU says batteries can provide backup for households and businesses. For companies, Sokolovskyi said, their economic value also includes losses avoided when essential operations continue during interruptions.
The wider need is substantial, according to Sokolovskyi. He said Ukrainian energy experts estimate the power system needs about 10 GW of new and restored generating capacity across different technologies. He also linked generation shortages and damage to electricity networks with recurring outages and increased reliance on imports from neighbouring EU countries. These are his account and an expert estimate; the source report does not provide an independent assessment of how much storage would reduce outages or imports.
Distributed generation and storage can add capacity closer to consumers and help critical facilities operate when external supply is interrupted. They cannot by themselves replace damaged transmission networks or meet every generation shortfall. The H1 estimate signals deployment activity, while the association’s conditional outlook underlines that further construction depends on practical and security-related constraints.
From 2025 Growth to 2026 Plans
SEAU’s figures describe a market that grew in 2025 and may continue expanding in 2026. The association reported 2.9 GWh of storage additions in 2025 and expects around 3.2 GWh for the current year. The source does not state a common measurement method or provide a detailed breakdown that would allow readers to compare the composition of the two annual totals. Sokolovskyi’s clarification that portable systems are included is relevant to interpreting the market figures.
For solar, the association estimates roughly 800 MW of additions in 2024 and 1.5 GW in 2025, compared with an expected 2 GW in 2026. SEAU says smaller, self-consumption-focused installations will make up much of this year’s project count. Lower equipment costs have made solar-plus-storage systems more accessible, Sokolovskyi said, and batteries can help users store solar output for later use and reduce electricity costs.
Policy and procurement developments provide additional context. Ukraine updated its solar feed-in tariffs earlier in 2026 and later introduced time windows for eligibility, according to the report. The state-owned JSC Guaranteed Buyer was scheduled to hold two solar auctions later in the week, offering a combined 150 MW. The source does not give auction results, so these are upcoming events as described in the report, not completed awards.
““Our 2026 outlook for both solar and storage remains conditional on security, access to financing and grid connections.””

Forecast Hinges on Security and Grid Access
The 1.6–1.9 GWh figure is preliminary, and the report does not specify when a final H1 total will be available or how the estimate was compiled. It also does not separate grid-connected batteries from portable systems or give capacity by household, commercial and utility-scale use. Those omissions limit comparisons across market segments.
The expected 3.2 GWh for 2026 is an indicative outlook, not a confirmed year-end result. SEAU says security, financing and grid connections could affect deployment; Sokolovskyi said forecasting through the end of 2027 is particularly difficult. The source does not quantify the contribution of each constraint, state how much planned capacity is already under construction, or estimate how much of the forecast could be delayed.
The report also does not establish how the new storage will affect outage frequency, electricity imports or the operation of critical infrastructure. Those outcomes depend on where systems are installed, how they connect to the network and when they can discharge. Further project-level and official data would be needed to assess those effects.
Auctions and Project Conditions Ahead
The two solar auctions scheduled by JSC Guaranteed Buyer later in the week were the next near-term market milestone identified in the report. They offer a combined 150 MW, but auction outcomes and any resulting construction were not yet reported. Solar procurement may add generation; the source does not say whether the auctioned projects include storage.
For storage and solar deployment more broadly, SEAU has called for faster restoration and protection of energy infrastructure, continued support for distributed generation, insurance and guarantees against war-related investment risks, and more predictable grid-connection procedures. Its other priorities include closer integration with the EU electricity market, accessible concessional financing and microgrids that combine solar and storage with other energy sources where needed.
The association’s next full-year figures will show whether additions approach its roughly 3.2 GWh storage outlook and 2 GW solar expectation. Until then, the H1 range remains a preliminary estimate, and the pace of further deployment remains tied to security, finance and connection access.
Key Questions
How much energy storage did Ukraine add in the first half of 2026?
The Solar Energy Association of Ukraine’s preliminary estimate is 1.6–1.9 GWh. The report does not give a final verified H1 total.
How much storage does the association expect for all of 2026?
SEAU’s indicative outlook is about 3.2 GWh in additions for the year. The association says the forecast depends on security, financing and grid connections.
Does the 2025 storage figure include portable batteries?
Yes. SEAU chairman Vladyslav Sokolovskyi said the association’s reported 2.9 GWh in 2025 covers multiple market segments, including portable battery systems used for backup power.
What did Ukraine add in solar capacity during H1 2026?
SEAU’s preliminary assessment puts solar additions at as much as 1.1 GW. It estimated total installed solar capacity at 9.4–9.7 GW by midyear.
What could affect further storage deployment?
SEAU identifies security conditions, financing and grid connections as factors affecting its outlook. The report does not quantify how much each could change the final additions.
