Battery Pack Prices Drop 45% Amid African Solar Push
Despite record-low costs for storage, infrastructure and regulatory investment are failing to keep pace with new solar capacity.

Is current government regulation doing enough to encourage investment in local renewable energy storage projects?
Stationary battery pack prices dropped to US$70/kWh in 2025, marking a 45% annual decline, according to the ESI Africa Energy and Storage Volume 5 report. Despite this increased affordability, current regulatory and infrastructure investment remains misaligned with the continent’s rapid solar growth.
Why it matters
The cost decline presents a major opportunity for grid stabilization, yet the lack of proportional infrastructure investment risks bottling up energy capacity. Bridging this capital gap is essential for integrating the 26GW of solar installed across Africa over the last two years.
Stationary battery pack prices reached US$70/kWh in 2025, down 45% from 2024 levels. While battery costs have plummeted, planners are still struggling to account for localized variables like battery degradation in extreme heat and varying regional freight costs.

The details
Battery viability depends on a complex interplay of deployment scale, thermal management, and financial logistics. In hot climates, stationary battery packs face accelerated degradation, which can compromise the economic utility of energy storage. Effective deployment also requires navigating regional import tariffs and freight expenditures, which act as overhead costs that must be managed alongside the falling base price of cell technology.
Timeline
2023-2025: Approximately 26GW of solar was installed across Africa.
2025: Battery pack prices fell to US$70/kWh, a 45% annual decline.
October 22, 2026: ESI Africa published the Energy and Storage Volume 5 report.
October 28-29, 2026: The C&I Energy and Storage Summit occurs in Johannesburg.
The Tech Race
The 26GW of solar installed across Africa between 2023 and 2025 has vastly outpaced current storage deployment. This report highlights a widening infrastructure gap that must be closed to maintain grid stability.
Investors and grid operators can leverage lower battery costs to improve procurement and cost certainty. Stakeholders will address these financial hurdles during upcoming industry discussions in Johannesburg.
The takeaway
While battery costs have hit a new low of US$70/kWh, the immediate next step is securing the necessary infrastructure funding to prevent grid congestion. Watch the outcomes of the C&I Energy and Storage Summit in Johannesburg for new guidance on overcoming regional financing and tariff barriers.
