The commercial battery comeback

Commercial and industrial (C&I) battery storage has long been the missing middle of the energy storage market.  It’s been too complex and expensive to scale like residential systems, but too small to compete with utility-scale projects. 

That may finally be changing. 

In this episode, Shayle sits down with Tim Hade, senior vice president at Voltus and founder of Brightfield Infrastructure, to discuss why C&I storage has historically struggled, why the economics are shifting dramatically, and why the next wave of distributed energy could be driven by commercial customers rather than utilities.

They explore the four revenue streams that are making batteries more valuable, from demand charge management to emerging capacity markets, and examine how declining hardware costs, stable federal tax incentives, and AI-powered automation are reshaping project economics. Tim also explains how aggregating thousands of commercial batteries into virtual power plants could help hyperscalers bring new data centers online faster while easing pressure on an increasingly constrained electric grid.

Shayle and Tim discuss:
- Why commercial battery storage lagged behind residential and utility-scale markets

- The four revenue streams driving today's C&I storage economics

- How rising electricity prices and capacity shortages are changing customer demand

- Why battery hardware costs have fallen by roughly one-third in 18 months

- How AI could reduce project transaction costs by as much as 90%

- The opportunity — and challenge — of aggregating thousands of distributed batteries into virtual power plants

- Why data center growth and "bring your own capacity" programs could accelerate C&I storage adoption

- Tim's outlook for the fastest-growing segment of the battery storage market
