Grid Shopper

A daily record of retail electricity supply offers in six deregulated states.

Every fixed-price offer on six official rate boards, tracked daily against its own market’s reference.

Every current offer against its local reference

Each offer is shown relative to its utility’s supply rate, or in Texas to the average 12-month offer in its delivery area. Below zero means cheaper than that local reference.

What the record holds

Grid Shopper snapshots every fixed-price offer on the official rate boards of Pennsylvania, Ohio, Illinois, Texas, Connecticut, and Massachusetts, alongside each utility’s supply rate, the procurement auctions that set it, and the share of customers who have left default service. Everything on the site is also available through a public API.

How this works
Grid Shopper snapshots each state’s official rateboard every day, reads the utilities’ default service filings and auction results, and forecasts household usage from weather. The pages describe the market; the blog carries our forecasts and their receipts. Nothing here is sponsored, and no supplier pays to appear.
