A new report from global law firm DLA Piper has charted how investors are reshaping their approach to battery energy storage systems (BESS), the technology used to store electricity from the grid or from renewable generation for use when demand requires it.

The Capital Unlocks Capacity report draws on a survey of 550 respondents across 11 markets, with respondents including private equity investors, institutional investors, commercial banks, developers and independent power producers.

The headline finding is straightforward enough. The US remains the most attractive market for storage investment, cited by 25% of respondents.

The UK follows in second place on 19%, ahead of China on 14%, while Germany, Canada and Australia each scored 11%.

The more revealing story, however, is found beneath those numbers.
