Correct Answer
2-4%

And here's something for you to take back

2-4% (vs 1%) might not sound like such a big difference, but when you factor in two trends - one, the scales of solar and wind farms are growing like crazy, and two, we are taling about 25 years of operations (almost 10,000 days of such O&M for each plant), a percentage difference in costs could mean a heck of a lot
