The accepted Hunter Valley access undertaking requires ARTC to submit documentation for the purposes of an annual compliance assessment conducted by the ACCC. In summary, section 4.10 and Schedule G of the undertaking requires the ACCC to determine whether ARTC has complied with the financial model and pricing principles specified in the undertaking and whether there has been any under or over recovery of revenue from users that needs to be reconciled.
In May 2013, ARTC submitted its annual compliance documentation for the twelve month period from 1 January 2012 to 31 December 2012. In June 2013, the ACCC issued a consultation paper and called for submissions from interested parties on ARTC’s documentation. Submissions closed on 10 July 2013. On 26 February 2014, ARTC submitted revised versions of its annual compliance documentation. In March 2014, the ACCC made a determination that ARTC's revised submission complied with the requirements of the undertaking. The outcome of this determination is that ARTC has capitalised cumulative losses of $10.44 million in Pricing Zone 3 and ARTC is entitled to recover an additional $4.82 million in revenue from Constrained Coal Customers.
