The problem of urban electric transport recuperation when using rolling stock from the secondary market is shown, which leads to the breakdown of wagons. Due to the existing legislation, electric trans is faced with the impossibility of returning the recuperation energy to the medium voltage network. To overcome the problem of increasing the voltage in the contact network, Pluton IC LLC proposed the use of transistor voltage limiters for dissipating energy on resistor blocks. The operation of the ONTr limiter for utilizing the recuperation energy is described. The potential is analyzed and a solution is presented that increases the overall energy efficiency in the system by using the recuperation energy in the form of heat for hot plumbing system or heating of a domestic room. To implement the method, the dissipative dissipation of braking energy into the air is replaced by the transfer of heat in a water-cooled resistor to flowing water, which can be used for hot water supply or heating. As a buffer, a water energy accumulator is required, with the help of which it is possible to level out the pulse nature of the dissipation. The results of the measurement of the recuperation energy that can be used for heating are presented. The area of the room that can be heated with this energy and the volume of water that can be heated for use are calculated. A carbon footprint of 9.9 kg was calculated, which allows for reduced use of a voltage limiter, and a comparison was made between emissions from vehicle operation and natural gas combustion. A proposal for the alternative use of recovery heat for hot plumbing system of domestic premises is put forward for discussion.
