## About Peak Energy

## Company Overview
- **One-liner**: Peak Energy designs and deploys next-generation sodium-ion energy storage systems for grid-scale and AI data center applications, offering the world’s first fully passive, drop-in compatible battery storage solution.
- **Entity Type**: Private (Series A – $55M raised in June 2024)
- **Headquarters**: Burlingame, California, USA
- **Founded**: 2023
- **Founders**: Landon Mossburg (CEO), Paul Durkee (CTO), Brandon Kelly (Chief Scientist)

## Core Business
- **Primary industry**: Energy storage / Battery technology / Grid infrastructure
- **Target customers**: Utilities, Independent Power Producers (IPPs), AI data center operators, grid operators (B2B, enterprise)
- **Mission or purpose**: Deliver the lowest cost electron to the grid, enabling the next era of AI, electrification, and renewable power through abundant, reliable, and domestically manufactured energy storage.

## Products & Services
- **Peak Passive Grid‑Scale Storage System**: A sodium‑ion battery energy storage system (BESS) designed for 20+ year life with zero scheduled maintenance, no augmentation, and passive thermal management. Drop‑in compatible with existing BESS installations, requiring no new installation crews or EMS integration playbooks. Achieves higher round‑trip efficiency (more power to GPUs) and lower total cost of ownership (claimed $75/kWh savings through minimal opex). Fully 48E ITC compliant. Deployed in partnership with nine of the largest U.S. IPPs and utilities.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total funding of **$65M** ($10M seed in October 2023, $55M Series A in June 2024)
- **Notable Investors/Partners**: Investors not publicly named; key partners include **GM** (partnership to scale next-gen energy storage), **Jupiter Power** (4.75 GWh contract signed November 2025), and nine of the largest IPPs/utilities in the U.S.
- **Growth Signals**:
  - First grid‑scale sodium‑ion system deployed in Colorado (August 2025) – world’s first passively cooled system.
  - Over 10 months of operating deployments; 9‑customer pilot completed.
  - **6+ GWh contracted through 2030** (including 4.75 GWh with Jupiter Power).
  - Scaling plan: 5 deployments in 2026, 1 GWh in 2027; U.S. factory (4 GWh capacity) planned for Q1 2027 SOP.
  - Signed agreement to deploy MISO’s first sodium‑ion grid storage battery (March 2026).

## Competitive Advantages
- **Lowest total cost of ownership** – passive cooling eliminates fan/chiller failures, no scheduled maintenance, no augmentation, reducing opex significantly.
