Example 11.10 (The utility’s put)
On the last thirty winters at O’Hare, detrended to the winter of 2026/27, the burn estimate of the season’s HDD is 4 677. A put struck 10% lower, at 4 209, paying $20 000 per HDD with a $20 million cap, would have paid in 20% of the adjusted winters: $0.61 million on average, $1.60 million in the 90th-percentile winter and $9.30 million in the warmest. Without the detrending the estimate is 4 871 and the average payout $0.56 million.
