System inertia as a barrier that holds back the acceleration of the energy sector development
This study is focused on the qualitative assessment of the barriers that hinder the acceleration of energy systems development. System inertia is one of the above barriers and as such, it is of tantamount importance. It is brought about by high capital intensity and material intensity of the electric power industry and the fuel industry as well as by the close direct and indirect production links they maintain with the machine industry, the iron and steel industry, and other industries that serve as their suppliers. We propose a system of performance indicators to characterize the property of inertia and the techniques for their estimation. The study reveals a nonlinear dependence of inertia on the acceleration rates of energy development. Furthermore, we elucidate the impact of imports from the industries related to the energy sector on its system inertia.
