Grid Storage: Exceeding 800 GWh by 2028

Battery Energy Storage Systems (**BESS**) are essential for stabilizing grids dominated by solar and wind power. This prediction states that the global cumulative installed capacity of grid-connected BESS will **exceed 800 GWh** before the end of 2028.

The Momentum is Exponential

The high **'Yes'** vote is a reflection of the market's current exponential growth trajectory. Key factors driving this massive scale-up:

  • **Decarbonization Mandates:** Government policies in China, the EU, and the US (e.g., Inflation Reduction Act) heavily incentivize large-scale storage deployment.
  • **Price Decline:** The continued, though slowing, decline in the cost of lithium-ion batteries.
  • **Grid Instability:** The critical need to solve peak-demand and intermittency issues caused by high renewable penetration.

The current pipeline suggests that reaching 800 GWh is a highly achievable target, driven by policy and economic necessity.
