Battery Storage Costs Decline Globally, Now Underpricing Gas Turbine Peaking in Most Markets

According to research by Wood Mackenzie, battery storage costs have decreased to the point where they now represent a more economical option than gas turbine peakers for electricity grid balancing in the majority of global markets. The analysis shows particularly strong competitiveness in regions with abundant solar resources.

Key details

In the Middle East and Africa, utility-scale solar photovoltaic power costs approximately $37 per MWh while four-hour battery storage has fallen to $80 per MWh, making the combined solution more cost-effective than gas peakers. Similar trends are observed in Asia Pacific, Latin America, and other regions with favorable renewable energy conditions.

Why it matters

The cost crossover represents a tipping point for renewable energy integration where storage solutions become economically viable without subsidies. This development could accelerate the retirement of fossil fuel peaking plants and accelerate adoption of solar and wind power paired with battery storage systems.

Context

The analysis examines levelized cost of electricity (LCOE) comparisons across different technologies and regions. The findings suggest that continued cost reductions in battery technology, combined with increasingly inexpensive solar power in many regions, are driving fundamental changes in grid economics and energy transition pathways.
