Tasmania achieved 100% renewable electricity generation on 15 March 2026, with the system being supplied entirely by hydro (approximately 617MW average) and wind generation (approximately 35MW average). Regional reference prices remained relatively stable around $96-107/MWh during this period, with brief fluctuations between 00:35-00:40.
This renewable milestone reflects Tasmania's abundant hydro resources operating at high capacity during what appears to be favourable water availability conditions, supplemented by modest wind generation. The binding transmission constraint T_BLINK_TV_NGZ with an extremely high marginal value of $7.3 million suggests significant network limitations affecting power flows, likely contributing to the price stability by constraining export capacity and keeping renewable generation captive within Tasmania.
