Received 05.03.2020 UDC 669.744.072.2/338.3 Ukraine has insufficient energy resources, which requires their annual purchase in a significant amount, both for the needs of industry and the population. Therefore, the development of renewable energy in Ukraine is an urgent task on an industrial scale. The constructions of wind power plants use rather large case cast parts, orders for which were distributed among European enterprises. The production of these castings is slowly being mastered in Russia, Ukraine and Kazakhstan at the modern technical level. Active development of demand actualizes the issue of choosing suitable technologies for such casting, and foundries with such technologies are guaranteed a steady increase in orders for the manufacture of castings for wind farms. The Physics and  Technology Institute of Metals and Alloys of the National Academy of Sciences of Ukraine has developed the casting technology for the Lost Foam Casting process (LFC) of body castings of such a plan. This article is devoted to this, with a list of options and a brief analysis of such an LFC process, which has a number of advantages due to the use of vacuum in sand molds, a bypassed gating system of a shaped configuration by polystyrene foam modeling, varying the location of the pattern in the mold of loose sand, etc. Castings for wind farms and other equipped I have renewable energy convincing perspective for the manufacture of domestic foundries in the most economical manner for such casting LFC. The active development of demand for such castings is caused by the construction of wind farms in the world and Ukraine, which with further growth guarantees foundries an increase in orders for the manufacture of such castings. Already, Ukraine is able to master and develop new foundry technologies for the production of innovative wind farms on the way to achieving the position of a manufacturer of equipment with high added value.
