The co-generation facilities have maximal thermal efficiency. In the case of the Russian Federation, for the power production industry, the development of the co-generation combined cycle facilities (CCGT-CHP) is especially urgent. The CCGT-CHP daily load schedule requires the demand of both electricity and heat, and the heat demand depends only upon the ambient air temperature. The gas turbine power reduction and the subsequent steam turbine power reduction during the electric load drop down are limited by the necessity to maintain the steam flow to district water heater to supply heat power. Methane steam reforming allows the recovery of the excess steam heat in the form of synthetic gas together with the CCGT-CHP electric power reduction. This paper considers three versions of the CCGT-CHP steam use in the Methane reforming: Bleeding steam supply, throttling of the heat recovery steam generator exit steam and the supply of this steam to the steam production in a steam transformer. Steam Methane reforming allows a reduction in the steam turbine supply power of 25% during the electric system power drop down. In the daytime, during the maximal system load, the produced synthetic gas is used and it is necessary to use the peak load gas turbine, which allows a 23% electric power increase. Energy storage by steam Methane reforming increases the contribution margin by 2.9%.
