• the best combination of high efficiency and low mass-dimension parameters for segment of 60-180 MW gas turbines

• high quality of output energy and good behavior at the unsteady conditions (thanks to single-shaft design as well)

• high efficiency (efficiency in combined cycle >50%, efficiency in cogeneration cycle >80%), that allows to reduce the cost of power generation

• possibility to use the different fuels: gaseous fuels (natural gas, oil gas) and liquid fuels (kerosene, diesel fuel)

• flexibility of integration of the GTD-110 and power plants on its base into the available infrastructure of power generating facilities

• assembly and commissioning of power generating plants in the shortest terms (supplying of the GTD-110 assembled on frame, using of advanced readiness modules)

• reduction of capital cost for power generating facilities upgrading / construction, reduction of operating cost
