RGGI Auction 1 was held on September 25, 2008 and monitored by Potomac Economics, an independent monitor of electricity markets retained to evaluate the RGGI CO2 allowance market. Potomac observed the auction and confirmed that there was no material evidence of collusion or manipulation by bidders, and that the vast majority of bids were consistent with competitive expectations.
*Note: Only six states (CT, ME, MD, MA, RI, VT) offered allowances for sale in Auction 1.
2. Auction Participation:
Electric generators and their corporate affiliates ("compliance entities") purchased 82 percent of the allowances sold in the auction.
The figure below shows the quantity of allowances purchased in the auction by each of three types of entities:
Compliance Entities: Includes all electric generators and their corporate affiliates

Quantity of Allowances Awarded By Type of Entity
3. Dispersion of Bids
Bids were widely dispersed across compliance entities and non-compliance entities.
Most of the bidders that submitted a large number of bids (e.g., at least 2 million tons which is 6 percent of the available supply) were compliance entities. Overall, compliance entities accounted for 80 percent of the quantity of bids submitted in the auction.
The following figure summarizes the quantities of bids submitted by all bidders.
