Canadian Solar Inc. (NASDAQ: CSIQ) saw its stock price plummet by 5.00% during Wednesday's intraday trading session, despite announcing new battery energy storage contracts in Germany and Canada. The sharp decline comes as investors appear to be concerned about the extended timeline for project deliveries and potential execution risks.

The company's subsidiary, e-STORAGE, secured a significant contract to provide a fully integrated energy storage solution for the Skyview 2 Energy Storage Project in Ontario, Canada. The project, with a capacity of 411 MW/1,858 MWh, is scheduled to begin shipments in February 2026, with commercial operations starting in the second quarter of 2027. Additionally, e-STORAGE signed a battery energy storage system supply agreement for a 20.7 MW project in Germany, with shipments set to commence in March 2026.

While these contracts demonstrate Canadian Solar's growing presence in the energy storage market, the extended timeline for project delivery – starting in 2026 – may have disappointed investors looking for more immediate revenue impact. The market's negative reaction could also reflect concerns about the company's ability to execute these large-scale projects effectively or expectations of even larger contracts. As Canadian Solar continues to expand its energy storage business, investors will likely keep a close eye on the company's ability to meet project milestones and translate these long-term agreements into tangible financial results.
