A Cold-Storage Facility in Jurong Is Now Part of Singapore's First VPP

In a city-state where every square meter of rooftop is accounted for, Blue Whale Energy is installing batteries. Not in vast, ground-mounted arrays, but in modular packs under the solar panels of a cold-storage facility in Jurong, a retail site in Tampines, and an office building in Aljunied [Entrepreneur Asia, October 2026]. The startup’s bet is that a distributed network of these small, commercial-scale batteries, when linked by software, can act as a single, dispatchable power plant for Singapore’s grid. It’s a classic virtual power plant (VPP) model, but one that founder Gabriel Lim is building from the ground up, literally, with proprietary hardware.

The full-stack wedge

Most VPP operators are software companies that aggregate existing third-party batteries. Blue Whale’s wedge is to own the full stack. It designs and installs its own modular, rooftop battery packs, connects them through a secure edge gateway, and uses proprietary software to control when they charge and discharge [UntroD, September 2025] [BackScoop, October 2026]. The company targets commercial and industrial customers who have the rooftop space but lack the capital or operational expertise to optimize a battery system. In exchange for hosting the hardware, customers get a share of the revenue Blue Whale generates by playing the energy markets.

The unit economics hinge on two revenue streams: energy arbitrage (buying power when it’s cheap, selling when it’s expensive) and providing grid stability services. The company claims a participating site can earn up to $278,000 per year, though the specific conditions for that maximum aren’t disclosed [LinkedIn]. The hardware itself is a 2 kWh modular pack built with lithium iron phosphate (LFP) chemistry, designed for a 20-year service life and what the company calls a "rack-free" architecture for large installations [UntroD, September 2025] [Lithtech Energy].

A founder with grid-level connections

The ambition here is not small, and neither is the founder’s profile. CEO Gabriel Lim previously co-founded Saleswhale, a Y Combinator-backed AI sales startup acquired by 6sense [bluewhaleenergy.com]. More relevant to building physical infrastructure, his public biography includes a stint as Joint Head of Corporate Strategy at Singapore state investment firm Temasek and a board seat at real estate giant Capitaland [FTLive, 2026] [Bloomberg]. In the tightly regulated, relationship-driven world of energy, that background is a tangible asset. The team also includes a hardware engineer who built high-performance EVs and a software engineer from the 6sense acquisition [bluewhaleenergy.com].

Traction, while early, is concrete. The company has secured the necessary electricity license from Singapore’s Energy Market Authority (License No.: EMA/RE/040) to operate and aggregate assets [RecordOwl, 2026]. Its seed funding has been assembled in stages, totaling a reported $4 million from a consortium of regional investors.

The regulatory and scale puzzle

For all its early momentum, Blue Whale’s path is paved with hard questions endemic to the VPP space. The model only works at scale, requiring hundreds of distributed assets to have meaningful grid impact. Customer acquisition for a capital-intensive, long-term hardware installation is slow. Furthermore, the revenue-sharing promise depends entirely on volatile energy markets and the grid operator’s willingness to pay for services. A year of unusually flat power prices could make the economics look very different.

The company’s most plausible answer to these risks is its full-stack control. By owning the hardware and software, it theoretically can optimize performance more aggressively than an aggregator of heterogeneous systems. Its partnership with UNIGRID to explore sodium-ion battery chemistry also suggests a focus on driving down the core technology cost [Yahoo Finance, June 2025]. The initial deployments are the first test of whether its promise of being "simple, safe, and profitable" resonates with enough building owners to begin building that critical mass.

The next twelve months

The immediate plan is to deploy the capital from its latest $4 million round to roll out more of its modular systems across Singapore [Entrepreneur Asia, October 2026]. The stated goal is an initial 8 megawatt-hours of capacity, though a timeline isn’t specified. The real milestone to watch won’t be a megawatt number, but the signing of a first anchor commercial customer outside of the initial pilot sites. That would signal that the value proposition is crossing from a novel experiment into a repeatable sale.

Doing a back-of-the-envelope check: if one of their 2 kWh modules can be cycled once daily, it might deliver about 730 kWh per year. At Singapore’s average commercial electricity price of roughly S$0.30 per kWh, the arbitrage opportunity per module is in the low hundreds of dollars annually, before grid services. That math forces two conclusions. First, the $278,000 customer revenue claim implies a very large, multi-megawatt-hour installation at a single site. Second, to make the unit economics work for a smaller building, the software must be exceptionally good at capturing high-value grid service premiums, not just daily price swings.

Blue Whale Energy isn’t just competing with other VPP startups. Its real incumbent rival is inertia,the default choice for a building owner to do nothing. To win, it must prove that becoming a tiny part of a virtual power plant is more profitable, and just as simple, as leaving that rooftop space empty.
