28	Notes:
29	* 6 of Maine's 9 COUs report their delivery rate to the PUC. The other three (all offshore islands) but have high supply and lower delivery costs. For this reason and because together they make up 0.0% of load, they do not substantively impact the average.

32	*** weighted average calculated for group of 6 COUs and group of 3 IOUs by dividing total cents by total kWH
