The BESS project, called Cald, will be a standalone system and is expected to come online in the first half of 2024.

Aypa turned its first energy storage project online in 2018, when it was called NStor C&I, before being acquired by Blackstone two years later, renamed Aypa Power and pivoted towards the utility-scale segment. The company recently secured a US$320 million line of credit to advance its projects.

CSI launched Solbank, a proprietary designed and manufactured energy storage battery solution, in September 2022. It is targeting a manufacturing capacity of 10GW by the end of 2023, and has deployed around 2.3GWh of BESS projects to date across the UK, US and Canada. Its pipeline as of end-January 2023 stands at nearly 25GWh.

Recent orders include 550MWh for a project in the UK and 2.6GWh for projects developed by UBS Asset Management.
