Powerline Raises $7M Seed to Scale AI-Driven Battery Portfolio Intelligence

We’re excited to share that Powerline has raised a $7M Seed round, led by MaC Venture Capital, with participation from LG Technology Ventures, J-Impact Fund, and other incredible industry partners.

Building for the reality of modern energy storage

Over the past several years, we’ve witnessed firsthand the unprecedented growth of energy storage — and the new challenges that come with scaling this quickly. Operating battery portfolios today requires far more than a strong forecast or a reliable optimizer.

Operators are navigating:

• Increasing portfolio-wide complexity

• Fragmented strategies across assets

• Growing market saturation and tighter margins

• Shifting volatility patterns

• Constantly evolving incentive structures

Together, these dynamics are reshaping what it means to run storage fleets effectively in modern power markets.

Powerline’s mission

At Powerline, we’re building the AI intelligence layer and digital testbeds for battery portfolios — software that helps project developers and utilities:

• Maximize revenue

• Accurately benchmark and monitor performance

• Scale operations with confidence and efficiency

Our goal is to help storage operators make better decisions under real-world constraints, not idealized assumptions.

Expanding globally

We’re proud to be expanding globally, with early traction in Australia and the UK — two of the most advanced and demanding storage markets in the world. We’re excited to continue growing across the U.S. and Europe in the year ahead.

We’re just getting started.
