Yesterday, Base Power announced a $1 billion series C, giving the residential battery company an eye-popping $4 billion post-money valuation. Base manufactures, installs, owns, and operates residential batteries — a vertical integration strategy that CEO Zach Dell says is the “magic” to beating utility-scale batteries on CapEx. The company also acts as an electricity retailer and sells generation capacity. So how does Base’s business model work? And what will it do with its new fundraise? In this episode, Shayle talks to Zach about Base’s business model, the vertical integration strategy, and the challenges ahead. They cover topics like: The customer value proposition: how customers pay for backup power and Base uses the batteries for grid services Bases’s “gentailer” business model in ERCOT, earning revenue from monthly customer fees, retail electricity sales, and battery arbitrage The regulated market approach, where Base sells capacity directly to utilities Base’s vertical integration strategy: from ground-mounted designs to decoupled installation processes Challenges like managing a fixed workforce amid fluctuating demand and the declining price volatility in ERCOT Resources: New York Times: Base Power, a Battery-Focused Power Company, Raises $1 Billion Open Circuit: Is this moment for distributed energy different?
