On 31 March 2010, the NSW Department of Environment, Climate Change and Water (DECCW) held the fourth auction of 200 credits under the Hunter River Salinity Trading Scheme (HRSTS). The credits have a 10-year life that begins on 1 July 2010 and ends on 30 June 2020. These credits will replace the 200 credits that expired on 30 June 2010. The next auction will be held in 2012.
Where and who
The auction was held at the Quality Inn Charbonnier, New England Highway, Singleton. Slattery Auctions Australia conducted the auction in accordance with the auction rules as detailed in the Hunter River Salinity Trading Scheme Credit Auction - Process and Rules. These rules were developed in consultation with the HRSTS Operations Committee, scheme participants and other stakeholders.
Eleven bidders, representing mining and power generation facilities, competed for credits. The majority of bidders represented organisations that were already participating in the HRSTS. Two companies present were not previous members of the HRSTS; however, they were companies associated with existing coal mine facilities. There were no registrations from non-industry bidders. Two community representatives, as well as representatives from the NSW Officer of Water and the mining industry, attended the auction as observers.
Results
The auction continued for the full 90-minute timeframe and six rounds of bidding were completed in that time. All 200 credits were allocated at the auction and the credits were distributed between 10 companies.
The auction raised $320,539. The average price paid per credit was $1603, an increase of approximately 69% on the 2008 auction results. The maximum and minimum credit prices were $2018 and $1402, respectively. The credit allocation and the cost to each organisation are shown in the following table.

Figure 1 below shows the highest, average and lowest successful credit prices offered for each of the six rounds. By the last round, the difference between the maximum and minimum successful bids was $616, which was 30.5% of the maximum bid per credit.
The rate of increase in the highest and average bids remained relatively constant throughout the auction until the final round. There was a marked increase in bid price in the final round of bidding (see Figure 1). This was consistent with the 2008 auction where bidding increased at a fairly constant rate until the bid price increased more steeply in the final rounds.
The decreased number of bid rounds (six in 2010 compared with 10 in 2008) does not appear to have changed this pattern of bidding. The rate of increase of bid price in the final round was greater than in previous auctions. Bidders continued to wait until the final round to place a large bid to secure credits, regardless of the number of rounds in the auction.
Revenue and costs
Revenue from the auction will be used to offset the HRSTS costs for the 2010/2011 scheme year.
Objectives achieved
The HRSTS auction process is designed to:
-
distribute credits to stakeholders who place the highest 'value' on the credits
-
provide equitable access to credits for all bidders, including new entrants to the market
-
ensure that all available credits are taken up (NSW Government not left holding credits).
To ensure these objective are met, the auction process:
-
allows bidders to be advised of the market value of credits as the auction proceeds
-
ensures bids are genuine and reduces the possibility of bidders defaulting on a winning bid
-
includes safeguards against anti-competitive behaviour (Department of Environment and Conservation 2003).
Against these objectives DECCW can report that:
-
all 200 credits were taken up and invoices have been forwarded to the successful bidders
-
there was no apparent anti-competitive behaviour
-
the auction distributed 130 credits between companies that are already HRSTS members and 100 credits to two new companies, who are associated with existing coal mines
-
one company only received a partial allocation of the credits it was seeking to purchase; this company strongly indicated its dissatisfaction with the outcome of the auction and indicated that it would have paid more for credits if the auction had continued
-
one company was not allocated any credits at auction; this company also expressed disappointment with the auction outcome.
Feedback received
Feedback on the auction arrangements and outcomes was sought from all auction participants and four submissions were received.

DECCW's response to feedback
The 2010 auction was reduced to 90 minutes duration with no minimum number of rounds, following feedback from the 2008 auction that the auction process was too long (at 10 rounds and 2 hours 48 minutes). Two auction participants at the 2010 auction were strongly of the view that six rounds of bidding were insufficient, in terms of understanding the auction process and price discovery.
Feedback indicated that the auction process is complex and should be reviewed. DECCW intends to coordinate a review of the auction process prior to the 2012 auction. The review will focus on simplifying the auction process with a view to moving to an online auction format for future auctions.
It should be emphasised that the auction is only one way in which credits can be acquired. The HRSTS online credit register allows members to trade credits as they are needed for the discharge of saline water.
