The role and contribution of P.I. Melnikov, Academician of the USSR Academy of Sciences; N.A. Tsytovich, Corresponding Member of the USSR Academy of Sciences; N.I. Saltykov, Professor, and V.F. Zhukov, Candidate of Technical Sciences, to construction of the Yakutsk Combined Heat and Power Plant are elucidated. These outstanding figures, known for their pioneering researches in different fields of the permafrost science and engineering, were actively and directly involved in the construction project, including the planning and design, foundation analysis, site investigation, foundation construction, and post-construction monitoring. The foundation condition at the plant site, the causes for talik development, and the dynamics of talik distribution since the beginning of the study are discussed. The reasons of the quite stable state of the plant facilities despite the widespread talik occurrence are explained.

Keywords: Yakutsk Combined Heat and Power Plant, permafrost, talik, ground temperature
