The video jumbles things up a bit. From what I understand there were joint ventures in Russia to produce F-class turbines of the Siemens and General Electric product families. Siemens had a joint venture with Power Machines, and General Electric's joint venture with Inter RAO is called Russian Gas Turbines.
If you go to news websites they will claim that the turbines are import substituted by 60% and 55% respectively. And that the turbine blades and combustion chambers are still imported.
But if you go to the website of Russian Gas Turbines, it states that they did joint work with other Russian companies to import substitute the turbine blades and combustion chambers as well. Basically General Electric provided design schematics for the complete gas turbine via a full license. Russian research institutes developed the materials for the hot part of the turbines, and tooling was bought for coating the turbine blades, their website states that they produced turbine blades and a combustion chamber in Russia in like late 2021. So at this point import substitution of the General Electric F-class gas turbine should be complete. There was an additional license deal agreement with General Electric to buy a full license for their much larger H-class turbines, signed in late 2021, which however fell apart with the sanctions.
Power Machines got fed up with Siemens telling them who they could and could not sell gas turbines to, after that incident when the Russian government tried to use Siemens gas turbines in Crimea and that sale got sanctioned by the Germans. So Power Machines decided to develop their own gas turbine family with their own resources and produce it. Government funds were provided. This way Power Machines neither need to pay royalties for licensing to Siemens nor do they need to be subject to sanctions. So they are developing the GTE-65 (F-class), and GTE-170 (E-class) gas turbines. Power Machines already produced large steam turbines, and Electrosila is in the same group and produces small gas turbines for APUs, so it is not like they did not have the expertise in house to design and make their own if they wanted to. Their gas turbines are in bench testing and expected to be in production in two years.
Unfortunately many of the large gas turbines in Russia, especially of H-class type, which were already installed will now be without spare parts or maintenance. The saga of the Nord Stream gas turbine repairs is just one instance of this and will repeat itself a little all over Russia. General Electric F-class gas turbines are fully import substituted, and the same could be done for Siemens F-class gas turbines if they wanted to. But maintenance and production of larger gas turbines is still a problem.
There is also the updated Soviet designed GTD-110M gas turbine by UEC Saturn but time will tell if they solved the reliability issues in it, like UEC Saturn claims, or not.
As for Fortum (Finland) and Uniper (Germany), they built gas turbine power plants in Russia to generate electric power with private capital. These power plants use large Western imported gas turbines which are now sanctioned from getting spare parts or maintenance. So I hope the Russian government gets this future to be scrap for nothing. Both Fortum and Uniper are state owned and this will cause them huge losses. And Russia gets scrap.
It is a good thing that after that experience in Crimea the Russian state finally decided that before massive serial installation into the Russian power grid any gas turbines need to be fully produced in Russia. Right now the dependence on foreign gas turbine imports for power generation is annoying but not critical. Much of the infrastructure in power generation from natural gas in Russia still uses less efficient much older Soviet era steam turbines.
Power of Siberia gas pipeline uses a mix of Aviadvigatel PS-90 derived gas turbines and the General Electric F-class gas turbine I discussed before so should have no issues.
