BNEF Forecasts Battery Storage Surge as Data Centers Drive Demand

Executive Summary

BloombergNEF's New Energy Outlook 2026 puts battery storage on a steep upward trajectory, with data center energy demand acting as the primary accelerant. Data centers are projected to triple their electricity consumption by 2035, requiring roughly 400GW of new battery storage capacity globally alongside 1,000GW of utility-scale solar. The report is unambiguous: fossil-fuel-dependent energy systems face structural cost disadvantages, while BESS and solar investors stand to benefit from both the data center buildout and energy security pressures created by ongoing geopolitical shocks. For InfraSale users, the signal is clear — battery storage demand growth is no longer a speculative thesis; it is a modeled, capital-weighted reality.

What Happened

BloombergNEF published its New Energy Outlook 2026 report last week, modeling energy system pathways through 2050 across multiple scenarios. The base case Economic Transition Scenario (ETS) projects market-driven outcomes, while the Net Zero Scenario (NZS) aligns with Paris Agreement targets. The report marks a notable update from last year's edition, citing three major shocks to the global energy system this decade: COVID-19, Russia's invasion of Ukraine, and the ongoing war in the Persian Gulf, including Strait of Hormuz disruptions.

Data center electricity use is projected to triple by 2035. BNEF estimates data centers will account for 23% of power demand in PJM, 18% in Malaysia, and 15% in the UK. Meeting that demand will require approximately 1,000GW of utility-scale solar, 400GW of battery storage, 370GW of gas generation, and 110GW of coal capacity by 2050.

Global energy transition investment hit a record US$2.3 trillion in 2025, consistent with BNEF's ETS projections. Investment is forecast to rise 19% between 2031 and 2035, with transport accounting for 58% of increased spending. However, reaching net-zero targets under the NZS would require annual low-carbon investment to average US$4.8 trillion through 2030 and US$7.7 trillion between 2031 and 2035 — figures far above current trajectories.

Solar crossed a major threshold in 2025, with 655GW of new capacity added globally, compared to just 75GW in 2016. Under the ETS, solar becomes the world's leading power generation source by 2032.

Why This Matters

The data center energy story is no longer confined to technology sector analysis — it is now a central variable in power market modeling at the highest level. When BNEF embeds data center load into its base case scenario, asset allocators, grid planners, and site developers need to treat that demand as a structural input, not a cyclical upswing.

The geopolitical dimension compounds urgency. BNEF analyst Isshu Kikuma noted that markets relying on oil-linked gas — particularly in Asia and Europe — are experiencing elevated power prices due to the Strait of Hormuz closure. Higher spot gas prices widen intraday price spreads, directly improving the revenue economics for battery storage co-located with high solar penetration markets.

Even in markets where coal remains domestically available, BNEF projects it will be outcompeted on cost by 2050, falling to half its current utilization under the ETS. The long-term direction of the cost curve is not ambiguous. What varies is the speed of transition — and geopolitical shocks are accelerating it.

The 6% rise in global power sector emissions projected by 2035, driven by data centers, is a politically visible number. It will draw regulatory attention in every major market, which itself becomes a catalyst for accelerated permitting of zero-carbon alternatives, including BESS.

Power & Interconnection Impact

The scale of capacity required to serve data center load is the defining grid challenge of this decade. BNEF's 400GW of new battery storage and 1,000GW of utility-scale solar — even spread across global markets — represent interconnection queue volumes that dwarf anything the industry has processed before.

In PJM specifically, where data centers are projected to represent 23% of power demand by 2035, transmission and substation infrastructure is already under severe strain. Industry context: PJM's interconnection queue reform efforts are ongoing, but queue backlogs measured in years remain the norm, not the exception. Battery storage projects co-located with solar or existing generation assets may have a meaningful queue positioning advantage in this environment.

Higher fossil fuel spot prices, driven by Hormuz disruptions, are repricing PPAs in real time across Asia and Europe. Markets with significant renewable penetration — where solar creates wide intraday spreads — are becoming the most economically favorable locations for new BESS deployment.

Land, Zoning & Permitting Impact

The land footprint implied by 1,000GW of new utility-scale solar and 400GW of battery storage is enormous. Even at a global scale, competitive pressure for permittable, grid-proximate acreage will intensify materially. Industry context: utility-scale solar requires roughly 5–10 acres per MW depending on terrain and panel configuration, placing the land requirement for projected solar additions in the hundreds of millions of acres globally.

Permitting timelines are a known bottleneck. In the US, environmental review and local zoning processes routinely add 2–4 years to project development. As data center operators push for faster power delivery timelines — often targeting 18–36 months from site selection to energization — pressure will mount on regulators and local governments to streamline approvals for co-located solar and BESS projects.

Local opposition to large battery storage facilities remains a real risk. Thermal runaway incidents at a small number of projects have generated community resistance in several US counties. Developers who invest in community engagement and fire safety infrastructure early are likely to see faster permitting outcomes.

Investment Takeaway

BESS is a primary allocation target. BNEF's 400GW global battery storage figure, tied to modeled data center demand, gives investors a demand-anchored underwrite that was previously speculative. The forecast validates BESS as a core infrastructure asset class.
Solar-plus-storage projects gain relative attractiveness. Co-located solar and BESS assets in high-penetration renewable markets benefit doubly — from wide intraday spreads and from data center operators seeking 24/7 clean power supply.
Fossil fuel-linked portfolios face structural repricing. Even under the base ETS (not the aggressive NZS), coal falls to half utilization by 2050. Investors holding unhedged thermal generation in competitive markets are holding a depreciating asset.
Grid-proximate land with interconnection rights is a premium asset. As queues lengthen and land competition intensifies, sites with existing interconnection agreements or substation access will command significant valuation premiums.
The US$4.8 trillion annual NZS investment requirement signals a financing gap. Current deployment at US$2.3 trillion is less than half the net-zero pace. Private capital — project finance, infrastructure funds, green bonds — has a structural role to fill.

InfraSale Market Angle

For investors actively deploying capital into battery storage and renewable energy infrastructure, the BNEF New Energy Outlook 2026 functions as a demand floor, not a ceiling. The data center load projections are based on announced hyperscaler capacity plans and AI infrastructure buildouts that are already underway — this is not a speculative scenario. Investors monitoring energy storage deal flow should treat PJM, the UK, and Southeast Asian markets as highest-priority geographies given their explicitly modeled data center load shares.

Developers and landowners sitting on grid-proximate acreage in these regions have a tangible valuation catalyst. The window to position assets before queue backlogs and land competition fully close remains open — but BNEF's timeline suggests it narrows sharply before 2032 when solar becomes the dominant generation source.

For utility and local government stakeholders, the 6% emissions increase tied to data centers is a planning assumption that should be embedded in integrated resource plans now, not after the capacity shortfall materializes.

FAQ

How is data center energy demand impacting battery storage?

Data centers require reliable, high-volume power delivery around the clock, which creates natural demand for battery storage as both a backup and a grid-balancing resource. BNEF projects data centers to account for 23% of PJM power demand by 2035, a load scale that cannot be served without significant BESS buildout alongside new generation capacity.

What are the investment opportunities in battery storage?

The most direct opportunities lie in utility-scale BESS projects co-located with solar in high-renewable-penetration markets, where intraday price spreads create strong revenue economics. Grid-proximate land with interconnection rights, BESS project finance, and equipment supply chain positions in lithium-ion and emerging chemistries are all areas attracting institutional capital attention.

How will energy policies evolve to support renewable technologies?

Industry context: the 6% projected increase in power sector emissions tied to data centers is likely to accelerate regulatory action favoring zero-carbon procurement mandates and permitting reform for solar and storage. Markets like the EU, UK, and several US states are already moving toward clean energy standards that would structurally favor BESS and solar over new fossil generation.

What does the Strait of Hormuz disruption mean for energy storage economics?

Closure of the Strait of Hormuz has elevated spot gas prices in oil-linked markets across Asia and Europe. Higher gas prices widen the spread between peak and off-peak power prices, improving the revenue case for battery storage systems that charge cheaply during solar hours and discharge at peak. BNEF analyst Isshu Kikuma explicitly identified this mechanism as a near-term tailwind for storage economics.

Is the 2°C climate target still achievable under current investment levels?

BNEF's modeling indicates that limiting peak warming to below 2°C is technically and economically feasible, but requires annual low-carbon investment to average US$4.8 trillion through 2030 — more than double the record US$2.3 trillion invested in 2025. At current trajectories, the world is on a path more consistent with BNEF's Economic Transition Scenario than its Net Zero Scenario.
