Genex Power Ltd (GNX.AX) Commencement of Underground Works at Kidston Hydro

Sydney, Australia, Jan 21, 2022 - (ABN Newswire) - Genex Power Limited (ASX:GNX) is pleased to provide the following construction update for the 250MW Kidston Pumped Storage Hydro Project (K2-Hydro or the Project).

COMMENCEMENT OF UNDERGROUND WORKS - MAIN ACCESS TUNNEL

During December 2021 and January 2022 (the Period) extensive works relating to the Main Access Tunnel (MAT) for the Project have been undertaken. The commencement of the MAT is ahead of the contract schedule and progressing well.

The MAT makes up a 1.5km long horseshoe profile having dimensions of approximately 6m wide and 6m high. It is graded at 14% (1:7) in a spiral to access the powerhouse cavern which is approximately 250m below ground level. The powerhouse cavern will house the two 125MW Andritz Hydro reversible pumpturbines. The MAT is constructed using conventional full-face drill and blast excavation methodology, with a single heading taking approximately 6 months to reach the first adit which will provide first access to the powerhouse cavern. Once the first adit is reached, multiple tunnel headings will progress to expedite the powerhouse cavern excavation.

With preparation works for the MAT completed in early 2022 including portal face stabilisation and preparation works, the EPC Contractor joint venture for the Project have formally commenced the underground excavation works with the first major blast for the MAT. Following this milestone, tunnelling operations are now progressing on a 24/7 basis with two shifts per day, which is scheduled to progress the tunnelling works at an average rate of 8m per day over the next 6 months.

CONSTRUCTION UPDATE - ONGOING KEY ACTIVITES

In addition to commencement of the underground works, site activity continues to ramp-up, with works commenced on the following near term construction milestones:

- Commencement of procurement and manufacture of key turbine components;

- Completion of the blast magazine storage area and access road;

- Near completion of the 22kV distribution line with transformer installed with final connection works still ongoing;

- Ongoing aggregate crushing plant and concrete batch plant operations; and

- Continuation of services reticulation around the site for construction purposes.

UPCOMING KEY CONSTRUCTION MILESTONES

- Commencement of full-scale prototype testing of electrical towers for the 186km 275kV transmission line being constructed by Powerlink Queensland; and

- 22kV electrical connection to Ergon Energy's Kidston substation allowing the removal of temporary electrical connections at the Project site.

The construction program remains on schedule for first generation in Q4 2024.

Commenting on today's announcement, James Harding, CEO of Genex said:

"Following an intense period of site establishment and preparation works, I am delighted that the EPC Contractor JV of McConnell Dowell and John Holland has formally commenced the underground excavation works for the Kidston Pumped Storage Hydro Project. This represents a significant milestone in the project construction timeline which was achieved ahead of schedule.

We look forward to working alongside the EPC JV and keeping the market updated as the program continues to push ahead over the course of this year."

Commenting on this construction milestone, McConnell Dowell CEO, Scott Cummins, who attended site this week, said:

"It is pleasing to see this iconic project launch successfully and reach this very important early milestone. McConnell Dowell, together with our EPC partner, John Holland are proud to be working with the Genex team to deliver Australia's first privately developed pumped storage hydro project."
