At least in Switzerland (Swissgrid loco), this is not true at all (for AS and frequency control) The complete process is documented end to end, free to see, and the enroll process in documented and "cheap" (~150kCHF, 100kCHF being for the warranty). You can start playing in the ancillary services field with 5MW, which is not that much. PS: If a company in CH needs help in that field (process approval or swissgrid-compatible IT systems), let me know !
