Tecogen: Huge Demand, Tiny Company

Tecogen Inc. is gaining traction in the data center market with its cost-efficient chillers, cogeneration products, also due to high gas turbine costs and limited supply. TGEN's management expects chiller data validation within 1 to 1.5 months, which could accelerate orders from data center operators. Valuation metrics show that TGEN trades above most peers on a price/sales and EV/sales basis, but growth expectations help justify the premium.
