A programme claims 50 MW of reduction, of which surveys suggest 20 per cent would have occurred anyway. The net reduction is

  • A.10 MW
  • B.60 MW
  • C.40 MW
  • D.50 MW

Answer: C

Correct answer: 40 MW

\[ 50 \times (1 - 0.20) = 40\ \mathrm{MW}. \] The gross figure counts everything the participants did; the net counts only what the programme caused. Since the programme is judged on cost per megawatt actually saved, the free rider adjustment can change a favourable evaluation into an unfavourable one.
