The other two TBMs, Lady Eileen Hudson and Kirsten, are already powering ahead excavating the main access tunnel and emergency, cable, and ventilation tunnel at Lobs Hole, so we\u2019re delighted to be starting this very long and deep headrace tunnel from Tantangara.&#8221;<\/p>\n<p style=\"text-align: justify;\">The plan for the Snowy 2.0 project is to deliver 2,000MW of pumping and producing capacity and 175 hours of storage following its completion.<\/p>\n<p style=\"text-align: justify;\">Launched for boring 15.4km of the 17km headrace tunnel, TBM Florence was named after Australia\u2019s first female electrical engineer, Florence Violet McKenzie (1890-1982). While the design of this 11m diameter Herrenknecht machine is suitable for managing hazardous dust and poor ground conditions while tunneling up to 450m underground, the determined date for the first power generation from the scheme is 2025, followed by progressive commissioning of its six generating units.<\/p>\n<p style=\"text-align: justify;\">Although the latest estimated budget for the project has been stated as A$5.1bn (\u00a32.9bn), Australian energy industry figure Ted Woodley recently wrote in the Sydney Morning Herald that: &#8220;The all-up cost had increased to A$10bn-plus (\u00a35.7bn-plus) as the underground power station and tunnels alone would cost more than $6bn (\u00a33.4bn), without taking into account the cost of the transmission connections.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>On 22 March 2022, with the attendance of representatives from project promoter Snowy Hydro, principal contractor Future generation joint venture \u2013 comprising Webuild, Clough, and Lane Construction \u2013 and the local community, the third and ultimate tunnel boring machine for Australian hydropower project Snowy 2.0 has been launched in New South Wales.
