An update from Tecogen ( (TGEN) ) is now available.
On January 6, 2026, Tecogen Inc. highlighted via a LinkedIn post and an investor FAQ that its natural gas and hybrid chillers remain highly relevant to data center cooling, even as designs evolve toward higher-temperature liquid cooling and potential chiller-free configurations. The company argues that data centers will continue to require significant chiller capacity for data hall cooling and turbine inlet cooling, and that its patented hybrid drive technology can also support chiller-free sites by powering large fan systems and enabling seamless fuel switching to reduce peak electrical demand. Tecogen positions these capabilities as a way for data centers facing tightening power constraints and more acute peak pricing to maintain or expand AI computing capacity without overburdening grid-supplied electricity, underlining a strategic opportunity for its technologies in large-scale facilities such as 250 MW data centers.
The most recent analyst rating on (TGEN) stock is a Hold with a $5.00 price target. To see the full list of analyst forecasts on Tecogen stock, see the TGEN Stock Forecast page.
