[Press Release] Recently, the International Energy Agency (IEA) released a new electricity report showing that wholesale electricity prices in major global economies have continued to rise since 2025. Significant year-on-year increases have been seen in Europe, the United States, Japan, and other regions, making high electricity costs a core pain point for households and businesses. Solar energy storage solutions have become a mainstream choice worldwide to address this issue, offering a practical way for users to reduce their electricity bills.[Press Release] Recently, the International Energy Agency (IEA) released a new electricity report showing that wholesale electricity prices in major global economies have continued to rise since 2025. Significant year-on-year increases have been seen in Europe, the United States, Japan, and other regions, making high electricity costs a core pain point for households and businesses. Solar energy storage solutions have become a mainstream choice worldwide to address this issue, offering a practical way for users to reduce their electricity bills.
IEA data shows that in the first half of 2025, EU wholesale electricity prices rose 30% year-on-year to $90 per megawatt-hour, with Germany, France, and the UK seeing increases of 37%, 45%, and 40% respectively. U.S. prices rose by approximately 40%, and Japan’s by 15%. Even in regions like Australia and India, where prices fell slightly, they remain higher than pre-2022 levels. Rising natural gas prices, extreme weather, and growing demand have pushed up costs, which are directly passed on to end users.
“My monthly electricity bill keeps going up, especially during winter heating and summer cooling peaks, accounting for nearly 30% of my family’s monthly expenses,” said Hans Müller, a resident of Berlin, reflecting the frustration of millions around the globe. Energy-intensive businesses are hit even harder, with EU industrial electricity prices twice those in the U.S. and 1.5 times those in China—squeezing profits and threatening small and medium-sized enterprises with production cuts.
Against this backdrop, solar energy storage systems— which combine power generation and storage—offer an effective solution. Unlike traditional solar panels, which only generate electricity during the day and feed excess power to the grid at low prices, these systems store surplus energy in batteries. Users can use stored power during peak hours (when prices are high) and recharge the batteries during off-peak hours (when prices are low), significantly reducing their overall costs.
Australia is a prime example: more than 250,000 households have installed energy storage batteries, with a total capacity exceeding 6.3GWh. Supported by government subsidies and proven cost savings, more families are adopting the technology. As solar and battery costs drop and policies improve, solar energy storage is becoming a necessity—one that promises to ease electricity burdens and drive the global energy transition.
