If they used that energy at 45 MJ/Kg that would be 45 trillion joules per year there is 3.6 million joules in a KWH. If 2 thirds of that was lost generating electricity that would be 15 million KWH a year.
My calcs are a little different, showing 1 MTPA to be roughly 659 megawatts of electric generator capacity running 24/7. Key conversion factors being 49,200 cubic feet per metric ton, .2931 watt-hours per BTU, 1,000 BTU/cf, 40% generating plant thermal efficiency.
So my bottom line would be that 1 MTPA would be plenty adequate for around 1,000 megawatts of electric power generation capacity. Somebody with a "rule of thumb" handbook should confirm.
Actually I got 4.5 billion KWH. This agrees with your numbers except that I used 33% effeincy,
