Tesla’s energy storage business gets sucked into the company’s downward spiral

Tesla's energy storage segment, once a beacon of promise for the company, is now feeling the effects of a broader downturn that has gripped the automaker. For the second quarter running, there has been a noticeable drop in the deployment of its Powerwall and Megapack products. According to recently released figures, Tesla managed to install 9.6 gigawatt-hours of storage in the second quarter, which marks a decline of 0.8 gigawatt-hours compared to the first quarter. The energy storage division experienced its high point in the last quarter of 2024, achieving deployments of 11 gigawatt-hours during that period. Over the course of the entire year, Tesla deployed a total of 31.4 GWh of energy storage products. Prior to this year, the sector had been a significant growth area for Tesla, with revenues from energy storage and solar solutions soaring from $2 billion in 2020 to an impressive $10.1 billion last year. However, the company’s sluggish start to 2024 indicates that this upward trend may soon come to a halt. In stark contrast, the overall energy storage market has been experiencing robust growth. Analysts from Wood Mackenzie reported that new installations reached an all-time high in the first quarter of 2024, demonstrating a remarkable year-over-year increase of 57%. Unfortunately, the momentum may not be sustainable, as new tariffs on imports from China and contentious legislative changes in Congress could hinder future growth. Republicans are currently working to amend significant elements of the Inflation Reduction Act, and while battery storage installations may still qualify for tax credits, new restrictions on materials sourced from foreign entities could complicate claims for these credits. It's important to note that a large portion of the minerals essential for battery production is processed in China, making these developments particularly concerning for Tesla's energy storage future.
