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

As data center-driven load growth continues to rise, hyperscalers are turning to natural gas – both in front of and behind the meter — to secure power. But whether the natural gas pipeline system has the bandwidth to support this surging demand remains far from certain.
Of all the concerns surrounding the AI boom, data center water usage tops the list. Opponents claim that massive hyperscaler facilities threaten local drinking supplies and drain aquifers. Proponents say data centers use a negligible amount of water, at least compared to agriculture or conventional power generation sources.
It’s been a wild few years for grid-scale batteries in Texas. At the start of the decade, the Lone Star State was home to roughly 200 megawatts of battery capacity. Today, that number has skyrocketed to seventeen gigawatts…with at least five more gigawatts expected to come online by the end of 2026.
