SNOWY 2.0 POWERING AHEAD WITH COMMISSIONING OF TUNNEL BORING MACHINE FLORENCE

22/03/2022

Snowy Hydro and members of the local community have today come together to celebrate the commissioning of the third and final tunnel boring machine (TBM) for Snowy 2.0, Australia’s largest renewable energy project.

The 143 metre-long TBM Florence is one of a trio of technologically-advanced machines excavating more than 27 kilometres of waterway tunnels as part of Snowy 2.0, the huge pumped-hydro expansion of the iconic Snowy Mountains Scheme that is ensuring Australia’s secure and reliable transition to renewables.

Snowy Hydro Managing Director and CEO Paul Broad joined Snowy Mountains community members and representatives from Snowy 2.0 principal contractor Future Generation Joint Venture for a celebration event and ribbon-cutting at Tantangara, where TBM Florence is being launched to excavate the headrace tunnel.

Mr Broad said it was a wonderful experience sharing a significant project milestone with the community, former Snowy Scheme workers and local school children and businesses.

“We want to thank the local community for their support. It’s great knowing that this massive project is delivering thousands of jobs, many training and apprenticeship opportunities for workers, and a major economic boost for the Snowy Mountains region and beyond,” Mr Broad said.

“The progress we’re making on Snowy 2.0 is terrific. 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’re delighted to be starting this very long and deep headrace tunnel from Tantangara.

“Watching TBM Florence’s big blue cutterhead spin today alongside people who helped build the original Scheme highlights the pride we at Snowy Hydro have in our pioneering past and how exciting the renewable energy future is with Snowy 2.0.”

There are almost 1,800 people currently working on Snowy 2.0, including hundreds of locals, with the project generating about 4,000 direct jobs and many more in the supply chain.

Snowy 2.0 will deliver 2,000 megawatts of pumping and generating capacity and 175 hours of storage – enough to power 500,000 homes simultaneously – which will underpin thousands of megawatts of intermittent renewables.

Named after Australia’s first female electrical engineer, Florence Violet McKenzie (1890-1982), TBM Florence is set to excavate 14.9 kilometres of the 17km headrace tunnel. The 11-metre diameter Herrenknecht-designed machine has been purposely designed to manage hazardous dust and poor ground conditions while tunnelling up to 450 metres underground.

TBM Florence was named by local Berridale student Riley Douch as part of the Snowy 2.0 Tunnel Boring Machine Naming Competition, which highlighted ground-breaking Australian women in science, technology, engineering and maths (STEM).

SNOWY 2.0 RAMPS UP WITH COMMISSIONING OF SECOND TUNNEL BORING MACHINE

06/12/2021

Snowy Hydro has today achieved another exciting milestone, with the commissioning of the second tunnel boring machine (TBM) for Snowy 2.0, Australia’s largest renewable energy project.

The 11-metre diameter TBM Kirsten, one of the most innovative and technologically-advanced machines in the world, is one of three TBMs that will excavate more than 27km of tunnels for the massive pumped-hydro expansion of the iconic Snowy Scheme.

Snowy 2.0, which is on-budget and due to produce first power in 2025, is fundamental to Australia’s transition to a renewable energy future. Its 2,000 megawatts of pumping and generating capacity and 175 hours of storage – enough to power 500,000 homes simultaneously – will underpin thousands of megawatts of intermittent renewables.

Snowy Hydro CEO Paul Broad said Snowy 2.0 was creating 4,000 jobs and significant training and apprenticeship opportunities for workers, while providing a major economic boost for the Snowy Mountains region and beyond.

“Our first TBM, the Lady Eileen Hudson, is already a kilometre into the mountain excavating the main access tunnel and now we have TBM Kirsten continuing the tunnelling and construction progress for this amazing project,” Mr Broad said.

“Our growing workforce of almost 1,400 includes hundreds of people from the local region and we have invested more than $70 million with local businesses so far.

“Upskilling workers and investing in the future of our youth will be important legacies of this project so it is very pleasing to see Snowy 2.0 apprentices around site learning their trades and local people having the chance to work on the TBMs.”

Mr Broad, Prime Minister Scott Morrison, Industry, Energy and Emissions Reduction Minister Angus Taylor, and representatives from Snowy 2.0 principal contractor Future Generation Joint Venture, today toured TBM Kirsten at Lobs Hole and watched the cutterhead spin.

Named after NSW astrophysicist and popular science communicator Kirsten Banks, TBM Kirsten is set to excavate the 2.9km emergency, cable and ventilation tunnel (ECVT), which provides alternate access to the underground power station. The 205-metre-long TBM will then bore the 1.4km inclined pressure shaft (IPS) and a 2.4km section of the headrace tunnel.

TBM Kirsten is setting a global standard in tunnel boring technology, just as the original Snowy Scheme developed rock bolting techniques that are still used throughout the world today.

It has been specially designed to excavate the IPS on a very steep gradient (to +47% or a 25-degree angle) so all equipment within the TBM can switch to work on the incline, and the stairways and walkways pivot to remain horizontal.

TBM Kirsten was named earlier this year by local student Kobe Burnes as part of the Snowy 2.0 Tunnel Boring Machine Naming Competition, which highlighted leading Australian women in STEM.

SNOWY 2.0 TBM NAMES ANNOUNCED

13/07/2021

Snowy Hydro is excited to announce the winning names for two of our Snowy 2.0 tunnel boring
machines (TBMs) – Kirsten and Florence.

Students in the Snowy Mountains were invited to nominate groundbreaking Australian women in the
fields of science, technology engineering and maths (STEM) for the Snowy 2.0 TBM Naming
Competition. Almost 3,000 people voted on a shortlist of six influential women, with astrophysicist
Kirsten Banks and electrical engineer Florence Violet McKenzie receiving majority votes.

We congratulate the two students who nominated these influential women: Kobe Burnes (Brungle)
choosing Kirsten Banks and Riley Douch (Berridale) selecting Florence Violet McKenzie.

Our student competition winners will receive prizes including a visit to the Snowy 2.0 construction
site to see their named TBM before it goes underground and a VIP experience for their class at the
Snowy Hydro Discovery Centre in Cooma.

The three Snowy 2.0 TBMs now all have names, with the first already titled the Lady Eileen Hudson,
in honour of the original Snowy Scheme ambassador and wife of inaugural Commissioner, Sir
William Hudson.

Tunnel boring machines are always named after women, a tradition stemming from the 1600s when
miners working underground prayed to Saint Barbara for protection.

Snowy Hydro, with its commitment to inspiring students to become the next generation of
innovators, asked local children in school stages 3-6 (years 5-12) to highlight the achievements of
inspiring Australian STEM women as part of the Snowy 2.0 TBM Naming Competition. More than 70
nominations were received from 15 schools throughout the Snowy Mountains region.

Kirsten Banks is an astrophysicist, science communicator and proud Wiradjuri woman. She loves to
share her passion for the stars and is well-known for her short and entertaining TikTok videos about
space and astronomy. Currently she is doing a PhD in the field of galactic archaeology, studying the
stars of the Milky Way to uncover secrets of its formation and evolution.

Florence Violet McKenzie (1890 – 1982), Australia’s first female electrical engineer, is best known for
her contribution to women’s technical education and for creating the Women’s Emergency Signalling
Corps during World War II. She taught women telegraphy so they could replace men in this civilian
occupation, however, she also trained more than 12,000 servicemen in morse code.
