Peak is an integrated energy company delivering the world's first fully passive grid-scale energy storage for AI data centers, utilities and IPPs. Grid operating deployments since August 2025; 6+ GWhs contracted through 2030; US manufactured.
What we do

The cheapest electron on the grid.

Since the beginning of civilization, availability of energy has defined what humans can build. The next era - AI factories, compute, autonomous industry - will be built on electricity that is cheaper and more abundant than any in history. Peak is building the company that delivers it: an integrated energy company anchored on the lowest cost electron delivered to the grid.

Our first product is the world's first fully passive grid-scale energy storage system: engineered to outlast its 20-year warranty without scheduled maintenance and drop-in compatible with any battery energy storage systems currently in operation. We deliver the lowest cost electron to generate tokens, power homes, and run factories. Today.

AI Data Centers

More tokens for the same power.
Compute scales only as quickly as power is available. Peak purpose-builds the most efficient energy storage solution for data centers, collapsing 4-7 year interconnect queues into compute that is online now. Our system covers every critical use case, from millisecond-long training spikes to multi-hour curtailment orders, while running silently, safely, and at 99.999% reliability. Higher round-trip efficiency means more power reaches the GPUs: 441 trillion additional tokens a year and over $4.7 billion in economic value across a 20-year project life. No chillers, no fans, no scheduled maintenance, just energy without limits.

Utilities & IPPs

Lowest total cost of ownership.
Built for the grid, proven at scale. Peak is a true drop-in for incumbent BESS: same install crews, same EMS integration, no new playbook to learn. A 20+ year design life with zero scheduled maintenance and no augmentation means a bankable asset you can underwrite with confidence, not a maintenance liability. Passive thermal management removes the components behind most BESS failures, unlocking higher uptime, lower opex, and a safer site near load centers. Peak has already deployed in partnership with nine of the largest IPPs and utilities in the United States, with grid operation for over 10 months. Systems are fully 48E ITC compliant and offer the lowest total cost of ownership, saving $75/kWh through minimal operating costs.
