If that scheme has a round trip efficiency of 75 per cent, the energy recovered is about
Answer: A
Correct answer: 409 MWh
The round trip efficiency applies to what comes back out:
\[ 545 \times 0.75 \approx 409 \ \mathrm{MWh} \]The 136 MWh lost appears as heat in the pumps, turbines, pipework and electrical machines. Note that the efficiency is a round trip figure, covering both the pumping and the generating passes; each individual conversion is nearer 87 per cent.
