What is driving it

How United Illuminating buys default service supply, and at what price

United Illuminating buys the power behind the price to compare in auctions held ahead of each service period; the latest reaches up to 15 months ahead. The price to compare is the average of what those auctions locked in.

Share of each month’s supply already bought, by auction, and the average price locked in
