When your power grid is about as reliable as a dial-up connection in a thunderstorm, you don't wait for the cavalry. You build the cavalry yourself. That’s exactly what Alexandra Rasch Castillo and Brian Pevear did with Caban Systems. Born in the aftermath of Puerto Rico’s post-Maria blackout blues, they didn’t just see a problem, they built a business blueprint around fixing it. Today, that blueprint just locked in a $50 million Series C, led by ClearSky Power & Technology Fund, with new energy coming from Shell Ventures and Inter-American Development Bank. BCP Ventures and Portfolia doubled down like they knew what was coming.
Let’s be clear: Caban isn’t another “green” pitch deck held together with vibes and Venn diagrams. This crew has receipts. We're talking 2.4 GWh of deployment capacity, over 1,200 operational sites, and a client list that includes American Tower, Enel Green Power, and the Puerto Rico Electric Power. In Latin America alone, they own 23% of the telecom energy market, and if you think they’re done, think again. Next stop: Southeast Asia, with Singapore on deck for Q3 2025.
The tech? Aura. Their Continuo 2.0 platform doesn’t just monitor, it predicts. Think AI that calls its own shots with 12-month failure forecasting. And their modular battery systems flex from 5kWh to 100kWh like a pro bodybuilder in a custom suit. This isn’t theoretical energy resilience, it’s 99.98% uptime with a 92% diesel reduction rate. In an industry built on promises, Caban delivers proof.
This round isn’t about capital, it’s about capacity. 45% of the funds are heading straight into scaling manufacturing. 30% is fueling R&D for solid-state battery systems. The rest? Opening up markets like the Philippines and Indonesia, where telecom towers still rely on diesel like it’s 1995. Caban’s playing a global game, but their playbook is local, modular, and brutally efficient.
What Alexandra and Brian built isn’t just a product line. It’s a movement engineered around autonomy, adaptability, and actual impact. CTO Brian Pevear brings 12 years of battery tech brilliance and an MIT brain to the equation, while Alexandra moves through the climate tech space like a storm in flats with honors from Forbes 30 Under 30 and Tesla credentials to boot.
$104.9M raised. A $520M valuation. 14 patents locked and loaded. And now, they're building toward hydrogen-ready systems and autonomous microgrids. The future isn’t just electric, it’s intelligent, interconnected, and infrastructure-obsessed.
