Coordinated expansion planning of power plants has always attracted the attention of power industry planners to arrive at the optimal mix that assures adequacy of energy supply. Here, we model the coordinates for expansion of electricity and gas networks while considering technical constraints, in order to minimize the total cost of investment and operation of electricity and gas networks for a single investor. Our study results indicate that we need to increase pipeline capacity in some areas in order to optimize our investment in the gas network foe Khorasan Razavi province. This additional investment only amounts to $ 19 million, which is insignificant compared to the total investment and operation cost of the gas network of $ 37.19 billion. The study also indicates need for power generation capacity in specified areas. These results also indicate that the capacity of some transmission line should be increased. When we take into account security needs at the N-1 benchmark level to deal with potential disruptions in gas pipelines, the electricity network would need to install around 3200 MW new generation units in different parts of the network to be robust against pipelines outages. While without considering the N-1 criterion for pipelines, the additional power generation capacity needed is only 2400 MW.
