# Peak Energy Raises $108M Series B Led by GM Ventures

> The sodium-ion battery company is preparing a U.S. factory and expanding toward data centers. The next test is turning customer orders into deliveries.

Peak Energy has closed a **$108 million Series B led by GM Ventures**, giving the sodium-ion battery company more capital to expand U.S. manufacturing and pursue customers building data centers.

The financing, announced on October 21, connects two investment themes: demand for AI computing and the power equipment needed to support it. Peak’s next challenge is to turn commercial demand into batteries delivered at scale.

The [company announcement](https://www.prnewswire.com/news-releases/peak-energy-raises-108-million-in-new-capital-announces-oversubscribed-series-b-to-scale-next-generation-energy-infrastructure-302914879.html) names Maverick Silicon, Infinite Capital, [Eclipse](/fund/eclipse), Xora Innovation and LG Technology Ventures as participants. A valuation was not disclosed.

## From customer orders to factory output

Peak says it has more than $1 billion in customer orders and plans to start production at its Sacramento factory in the first quarter of 2027. The facility is designed for 4 gigawatt-hours of annual manufacturing capacity.

That capacity describes the amount of battery storage the factory could produce in a year. It does not describe electricity generated by the factory or prove that production has already reached that level.

Orders and delivered revenue are also different. Building a manufacturing business requires equipment, materials, staff and customer approvals before much of the cash from finished products arrives.

[Dow Jones Newswires, published by MarketWatch](https://www.marketwatch.com/story/peak-energy-raises-108m-in-funding-round-led-by-gm-ventures-e0beed91), reports that the financing will support domestic production, customer orders and Peak’s entry into the data-center market. It also notes the company’s existing battery-development partnership with GM.

## Why simpler cooling matters

Peak builds large battery systems using sodium-ion technology. Its approach avoids conventional active cooling equipment, which the company argues can reduce maintenance and operating costs.

The commercial logic is straightforward: a battery’s purchase price is only one part of its cost. Owners also pay to operate, maintain and eventually replace equipment.

Peak claims its system can reduce energy costs by up to 20% compared with conventional storage systems. That is a company claim, not an independently verified saving for every installation. The comparison depends on the project, operating conditions and equipment being replaced.

A useful customer comparison would put purchase cost, usable capacity, maintenance, operating life and warranty terms side by side. A lower-cost design must still work reliably over years of service.

## Batteries help manage power; they do not create it

Storage can hold electricity and release it when it is needed. That can help an operator manage peaks in demand, but it does not remove the need for electricity supply and a grid connection.

This distinction matters in the AI buildout. Funding a battery manufacturer is a bet on one part of the power system, rather than a complete answer to every data-center constraint.

Other companies address different parts of that system. [VECKTA](/veckta-11m-series-a-onsite-energy-procurement) helps businesses procure onsite energy projects, while [Rabot Energy](/rabot-energy-50m-series-b-household-virtual-power-plant) coordinates household energy assets. These are related opportunities with different customers and business models.

## What the funding needs to achieve

For Peak, the clearest milestones are production starting on schedule, customer orders becoming deliveries, and field performance supporting repeat purchases.

Investors will also need to see the economics of manufacturing: how much it costs to produce each system, how quickly the factory reaches efficient output, and how much cash is tied up before customers pay.

The $108 million gives Peak resources for that transition. GM’s involvement adds an industrial relationship to the investor list. The result will be judged by factory output and reliable installations, rather than the size of the funding announcement.
