OJSC “Institute of applied research in power engineering” started its activity in 1995 when general works concerning research of efficiency of cogeneration technology in the system of municipal heat supply began by the initiative of general director of the plant “Komunarsk heat networks” (Zaporizhzhya) Sabashuk P. P. in the Institute of technical thermal physics of National academy of sciences of Ukraine. The head of the Institute is Corresponding Member of National academy of sciences of Ukraine Doctor of Science, prize-winner of the State prize of Ukraine Klimenko V. M.

The novelty of developing technologies was the principle of “energy superstructures” on base of existing boilers and industrial heat technologies because for usage the type of energy that limits is namely heat energy. For the purpose of effectiveness increase of heat and electric energy combined production it was suggested to take nominal electric power of superstructure according summer heat load, and during heating season to increase heat productivity due to combustion of additional fuel in the boiler-utilizer. First publications and patents of Ukraine and Russia about methods of realization refer to the period 1997-98 years.

Works of the Institute in the field of cogeneration technologies during 1995-2005 years:
