Temasek leads US$80 million funding in power infrastructure provider Amperesand

[SINGAPORE] Amperesand, a next-generation power infrastructure provider for artificial intelligence (AI) data centres and critical power applications, raised US$80 million in an oversubscribed Series A funding round that closed on Tuesday (Nov 18).

Co-led by Walden Catalyst Ventures and Temasek, the round welcomed new investors – Industry Ventures, Acclimate Ventures and SG Growth Capital – as well as the continued participation of Xora Innovation, Material Impact, TDK Ventures and Foothill Ventures.

Amperesand said that its medium-voltage solid-state transformer (MV SST) platform cuts installation labour needs in half and accelerates time to power by 10 times, through an integrated design unifying hardware, software and intelligent controls into a single ultra-compact product.

The resulting reduction of more than 80 per cent in electrical footprint and simplified civil works allow for faster, more flexible expansion of high-power facilities, it said in a statement.

The funding will support Amperesand’s deployment of 30 megawatts of commercial systems next year, with a focus on hyperscale AI customers.

The company will also expand its engineering and manufacturing operations in the US and Singapore to meet growing global demand for critical power solutions.

Amperesand said it is delivering its first commercial units early next year to the Port of Singapore, supporting a mission critical charging pilot with PSA International.

It added that multiple additional commercial pilots in 2026 have been secured to enable hyperscale AI customers to achieve fast deployment of next-generation graphics processing units with Amperesand’s MV SST-based power architecture.

Chief executive and co-founder Brian Dow said that with AI data centres and other critical power systems becoming economic and national security interests for many countries, Amperesand’s MV SST platform “enables in-country cybersecure controls and data, regionally available supply chains, and low capital expenditure intensity local manufacturing”.

Walden Catalyst Ventures’ founding managing partner, Young Sohn, noted that the company is tackling one of the biggest bottlenecks in data centre power delivery.

“AI is redefining the limits of computing,” he said. “But without a revolution in power infrastructure, this growth simply can’t scale.”

Where it all started

Amperesand was incubated by Xora Innovation and spun out of Singapore’s Nanyang Technological University in 2023.

Last year, the company successfully completed full-power, overload and bidirectional testing of its Generation 2 system – scalable, foundational blocks for its commercial MV SST platform.

This year, it expanded in the US with the establishment of engineering and advanced manufacturing hubs in San Francisco and Reno. By the end of 2025, Amperesand expects to exceed 100 employees globally.
