ADVICE

Guarantee Backup By Reserving 20 Percent Capacity

Guarantee backup by reserving capacity; Base keeps a 20% state of charge guaranteed for customers while operating batteries for market services.
They deploy much larger 25–50+ kWh systems so reserved 20% still provides meaningful backup.

INSIGHT

Behind The Meter Sidesteps Utility-Scale Cost Drivers

Base avoids utility-scale line items like land, interconnection, queue delays and EPC margins by using behind-the-meter assets and in-house manufacturing.
They target margins above the cell (power electronics, pack design) and optimized installs to reduce total landed cost.

INSIGHT

Design For Grid Performance Not Just Consumer Appeal

Performance, reliability, safety and useful life matter as much as low CapEx; designing for grid markets requires different engineering than consumer-focused products.
Base emphasizes high-temperature, humidity and lifecycle performance to ensure asset value over 15+ year models.

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
