You can build a controller for much less than $800 per ECAT. I would expect that function to cost more like $50, which is on the high side. He uses the word computer if I recall correctly and that suggests something more complicated than a completed PLC. Since a microprocessor is sometimes referred to as a computer, I think that is what he is describing.
Perhaps I read you wrong about how he should be concerned about SCATA systems. I got the impression that you thought that he was planning to control numerous 100 Megawatt systems from a central location. But he is only dealing with one at the moment. One can easily be controlled without having to worry about the Russians.

Why would you not think that each small ECAT unit has its own microcontroller? This is what a PLC is. It is a few analog to digital converters, a microprocessor, a PROM, a bus comm controller, and a power supply. It cost about $800. There are approximately 100 individual ECATs and he has chosen to control each one independently while a main control system coordinates them. This is what a SCADA system is.
