This generator is one of the fastest generators passing BigCrush. Electricity is generated by fuel oil driven generators. ICEs drive large electric generators that power electrical grids. Similarly, XOR can be used in generating entropy pools for hardware random number generators. Xcel Energy has contracts for about 110 megawatts of electricity from biomass generators. Onboard electricity requirements are met by four MTU diesel generators. They were powered by four General Electric turbo generators rated at . Little fuel remained to power emergency generators. This is essential for keeping large generators and motors running smoothly. Major problems with the main turbine generators were found in June 2016. Electrical capacity is increased by three 60 kVA generators. Alternator regulators are also simpler than those for generators. Alternators have several advantages over direct-current generators (dynamos). Each plant consisted of four diesel generators and eight turbo-generators. Electrical power is supplied by three MHW-RTG radioisotope thermoelectric generators (RTGs).
