How could the global shift toward cheaper battery storage affect Japan's energy import strategy?
Global energy transition may reshape Japan's import reliance on natural gas The survey reported that battery storage is now cheaper than open-cycle gas turbines in every market surveyed, while solar is the cheapest form of new power globally. This shift is driven by rising prices for gas turbines, which are being pushed up by AI data center developers buying up available models. For Japan, a major energy importer, this global trend of cheaper alternatives and more expensive fossil fuels could force a re-evaluation of its energy mix and long-term import dependencies.

How it reaches Japan
-
Wood Mackenzie surveyed markets across the Middle East, North America, and Africa on October 9, 2026, finding that four-hour duration batteries are less expensive than open-cycle gas turbines in all 43 markets surveyed. The consultancy predicts that the cost of electricity from batteries will continue to decline, while electrons from gas turbines will become more expensive in the coming decades.
The full event1independent outlet -
The rising demand from AI data center developers has driven up prices for gas turbines globally. As these turbines are often used by utilities as peaking power plants, their increased cost raises operational expenses for utilities worldwide, including in major importing economies like Japan.

Why it matters
As a major energy consumer, Japan's economy is highly sensitive to global energy price volatility and the cost of imported fossil fuels. The reported shift toward cheaper renewable and storage solutions challenges the long-term viability and cost-effectiveness of natural gas, which has historically been a crucial component of Japan's energy security and supply chain.
This trend reflects a decisive global economic shift, as noted by Wood Mackenzie's principal analyst, Ahmed Jameel Abdullah. While some markets, like North America, have specific protections for utility-scale solar, the overall global trajectory suggests that energy generation costs are decoupling from traditional fossil fuel reliance, putting pressure on all nations reliant on imported energy.
