The Tasmanian region saw negative energy prices on the afternoon of 21 March 2007. Nearly 90% of the Tasmanian generation capacity was offered in the negative price bands. This resulted in negative energy prices and non-physical loss (NPL) correction re-runs for six dispatch intervals (DI) between DI 13:00 and DI 13:30, except for DI 13:10.
This report has been prepared to review the NEM pricing when negative prices and non-physical losses (NPL) occurred on 21 March 2007. This event had raised some interest from participants. The pricing outcomes were in accordance with NEM design but it is recommended that further analysis be undertaken in setting the trigger which invokes a NPL run.For enquiries regarding this document, please contact: Shantha Ranatunga, Market Review and Process Implementation
