Unlocking up to 30% more power for compute - Tecogen Launches Dual-Power Source Chiller for Data Centers

North Billerica, MA - October 2, 2025 - Data centers today are in a race against time. With the power demands of AI chips surging and existing grid capacity strained to the limit, every megawatt counts.

For years, the significant power consumed by cooling - nearly a third of a data center's available power - has been viewed as a necessary and fixed cost of doing business. According to Tecogen Inc. (NYSE American:TGEN), a leading manufacturer of clean energy products, it doesn't have to be that way.

Operating seamlessly on natural gas, electricity or both, Tecogen's TECOCHILL® Hybrid-Drive Chiller automatically shifts load to natural gas when cooling demand spikes. During off-peak operation, Tecogen's Hybrid-Drive chiller optimizes itself for maximum greenhouse gas savings by operating as a high efficiency electric chiller or using a combination of electricity and natural gas.

By fuel switching during peak cooling needs, facilities instantly gain back electrical capacity for IT, turning cooling into a profit driver instead of a bottleneck.

Two fuel sources also means uninterrupted cooling in a utility outage and twice the resiliency.

"We designed our solution with operators' realities in mind," said Abinand Rangesh, Tecogen CEO. "With the Blackwell chip doubling power needs per chip, the last thing operators need is for their electric chillers to eat 30% of their available power. What if they could cool their facilities with the same efficiency as electric, without sacrificing megawatts of power?"

Tecogen delivers a powerful combination of efficiency, resiliency and sustainability, giving data centers the ability to unlock new capacity and cut costs without compromising sustainability. Key benefits include:

• Increased IT Capacity - Free up to 30% of utility power by shifting cooling to natural gas, dedicating more electricity to servers and AI workloads.
• Lower Operating Costs - Natural gas is significantly cheaper per energy unit, reducing long-term expenses.
• Reduced Infrastructure Burden - Minimize the need for oversized backup generators and chilled water storage, creating a more resilient, uninterruptible cooling source.

The dual-power source chiller is offered in 1MW air-cooled models, eliminating cooling tower needs and water-cooled units up to 1.5MW. Scalable configurations let operators reclaim megawatts of capacity without touching grid infrastructure.
