ПРИМЕНЕНИЕ МЕТОДОЛОГИИ ПРОЕКТНОГО БЕНЧМАРКИНГА К ГЕОТЕРМАЛЬНЫМ ПРОЕКТАМ

Abstract:
The purpose of the article is to test the methodology of system benchmarking, previously developed and used for oil and gas projects, on a new class of objects for it – geothermal field development projects and the construction of power plants – for subsequent evaluation of promising projects in Kamchatka, including the second stage of the Mutnovskaya GEOP. The geothermal project in the study is understood as a complex of works covering the study of the resource base, drilling of production and injection wells, creation of field infrastructure and commissioning of generating capacities. The scientific novelty consists in adapting the unified form of data collection to the industry specifics of geothermal projects: 62 parameters characterizing the resource base, coolant properties, well parameters and the technological scheme of the power plant have been added to the basic 240 parameters, which corresponds to an increase of about 26%. The possibility of applying the UCCI cost index to this class of facilities is substantiated due to the similarity in the structure of capital expenditures of geothermal and oil and gas projects. Research methods include selecting analog projects based on installed capacity and availability of reliable data, collecting information from reports from international credit institutions and open sources, structuring project parameters, and bringing costs to a single date. Using the example of projects for the development of geothermal fields and the creation of generating capacities Lahendong 5-6 in Indonesia and Menengai in Kenya, it was found that with comparable unit capital expenditures of about 2.25 million dollars. USD per 1 MW – the full implementation period differs by more than one and a half times: 92 and 151 months, respectively. At the same time, the construction of the power plants themselves took 22 and 20 months, and the main duration of the projects was spent on preparing the resource base, drilling, financing and administrative procedures. The differences are due to the predominance of different types of risk: technical, related to the intake capacity of injection wells, in the Lahendong 5-6 project, and institutional, land and financial, in the Menengai project. The practical significance of the results is to substantiate the expediency of considering binary modules using spent steam when choosing a technological scheme for future geothermal power plants in Kamchatka, as well as the need to take into account administrative and organizational risks when determining the timing of projects.
