Global demand for battery energy storage systems (BESS) is entering a sharp acceleration phase, driven by rapidly falling costs, rising electricity demand from AI infrastructure, and tightening energy security concerns, according to UBS.
In a recent report, the bank said global BESS demand could reach 1.6 TWh by 2030, up about 6% from prior estimates, with the US and other regions seeing the strongest upward revisions.
UBS also expects US demand alone to triple to around 200 GWh by the end of the decade.
“In our view, renewable and storage emerges as the default near-term solution for reliable, dispatchable power,” analysts wrote.
“Data centers, a forecast 30% decline in BESS system cost and double-digit IRRs create a clear inflection point.”
The bank estimates US onshore battery cell costs are more than 30% below consensus expectations, a shift it says materially improves project economics and accelerates deployment timelines.
Analysts also point to growing demand from data centers as a structural new driver of grid flexibility needs.
UBS’s outlook implies a broader reshaping of the energy and materials landscape. Analysts did not name individual upstream companies but said that faster-than-expected growth in battery storage demand could tighten lithium balances over the medium term, potentially widening structural deficits as deployment accelerates globally.
In that broader thematic context, several companies across the Proactive coverage universe in lithium, battery materials, and grid infrastructure stand as potential beneficiaries of the trend.
Century Lithium Corp. (TSX-V:LCE, OTCQX:CYDVF) is developing a Nevada-based lithium project and is positioned within the expected rise in demand for battery-grade lithium as BESS deployment scales globally.
First Phosphate Corp. (CSE:PHOS, OTCQX:FRSPF, FRA:KD0, OTC:FPHOY) is focused on phosphate-based materials used in lithium iron phosphate (LFP) batteries, a chemistry UBS highlights as increasingly important in grid-scale storage due to cost and supply chain considerations.
American Resources Corp (NASDAQ:AREC) is developing exposure to graphite and other critical minerals, also a part of the wider battery materials theme.
Grid infrastructure and power systems
UBS highlighted that falling storage costs are improving project economics for renewables-plus-storage systems and increasing demand for grid flexibility solutions, particularly as electricity demand rises from data centers and AI infrastructure.
That’s good news for Ideal Power Inc (NASDAQ:IPWR, FRA:5ILA), which operates in power electronics for energy storage and renewable systems, an area that benefits from increased deployment of grid-scale storage and the need for more efficient energy conversion technologies.
Companies such as New Era Energy & Digital (NASDAQ:NUAI) and Digi Power X Inc (NASDAQ:DGXX, FRA:1NQ0, NEO:DGX) are exposed to the intersection of digital infrastructure and rising power demand, where data center growth is increasing pressure on grid capacity and supporting investment in storage-linked solutions.
VivoPower PLC (NASDAQ:VIVO, FRA:51J) provides indirect exposure to broader electrification trends through its linkage to large-scale, service-based BESS deployment.
Next-generation and early-stage technologies
UBS noted that while lithium-ion batteries (particularly LFP chemistry) are expected to dominate storage deployment through 2030 due to cost and scale advantages, alternative long-duration storage technologies are emerging over the longer term.
Within this broader innovation landscape, Graphene Manufacturing Group Ltd (TSX-V:GMG, OTCQX:GMGMF) is working on graphene-enhanced energy and materials technologies, which could contribute to incremental efficiency gains in battery systems but remains an indirect exposure to core BESS demand growth.
In the critical minerals development space, companies such as M2i Global Inc (OTC:MTWO) and Highland Critical Minerals Corp (CSE:HLND, FRA:U8X) are part of the early-stage exploration and supply chain development ecosystem, which could benefit from tightening battery material markets but remain highly sensitive to project execution and commodity price cycles.
China remains dominant cost leader
Despite the bullish outlook for Western markets, UBS emphasized that China remains the undisputed leader in battery storage manufacturing, with projected domestic BESS growth of around 40% compound annual growth through 2030, potentially reaching 1 TWh of demand.
However, the report noted that geopolitical restrictions and subsidy frameworks in the US and Europe are effectively reshaping supply chains, limiting Chinese participation in Western markets while supporting domestic and allied-nation producers.
China retains a structural cost advantage in lithium-ion production, but policy fragmentation is increasingly defining where capacity is deployed, UBS said.
Investment implications
Overall, UBS argues that falling battery costs and rising electricity demand are reinforcing a structural shift toward renewable-plus-storage systems, with implications across the entire energy value chain.
The bank sees particular benefit for battery manufacturers in South Korea, US renewable developers, and lithium producers, while also highlighting upside for grid infrastructure and power electronics companies tied to storage deployment.
