Blue Whale Energy Pte. Ltd. is a Singapore-based company focused on transforming unused rooftop spaces into profitable assets through innovative battery storage systems integrated with solar technology. Founded in 2024 in Singapore, Blue Whale Energy specializes in creating distributed battery storage systems that optimize the use of rooftops for energy generation.

Blue Whale Energy specializes in transforming unused rooftop spaces into revenue-generating assets through its core offering of distributed battery storage systems, which integrate seamlessly with solar panel installations. Utilizing sodium-ion technology, these batteries are designed for safety, quick installation, and minimal infrastructure requirements.

The company's products enable industrial building owners and solar developers to maximize the utility of their rooftops by participating in energy markets, particularly during peak electricity demand periods. The end use cases primarily focus on providing clean, stored power to displace polluting peaker plants, thereby contributing to sustainability goals and reducing overall energy costs. Blue Whale Energy targets industrial buildings and solar developers across various geographical markets, including North America and Europe, aiming to broaden its footprint in regions with high energy consumption and a strong commitment to renewable energy solutions. Blue Whale Energy's revenue model is structured around partnerships with industrial building owners and solar developers, focusing on the provision and installation of battery storage solutions.

Typically, the company covers all costs associated with the batteries and their installation, allowing clients to benefit from zero upfront capital expenditure. Revenue for Blue Whale Energy is generated through the participation of their battery systems in ancillary energy markets, where they earn payments for providing grid stability during peak demand. The automated bidding system enables these battery installations to capitalize on fluctuating electricity prices, further enhancing potential revenue streams for clients. By integrating their battery packs into existing solar projects, the company promotes a higher return on investment, ensuring that their partners can access new revenue opportunities while contributing to sustainability efforts.

In September 2025, Blue Whale Energy Pte. Ltd. raised an undisclosed amount in venture funding from new investors UntroD Capital and YAMADA SHOKAI Holding. The company will use this funding to accelerate the development of battery packs, create a basis for large-scale deployment in Singapore, and expand into the ASEAN and Japanese markets.
