experienced power industry project management team and have already set up strong process controls. Mohsen Moeini is a specialist hydropower engineer with extensive international experience designing pump-hydro projects. Kari McDonald’s environmental and permitting experience in Alberta includes working on another major Alberta pump-hydro project. David Lawrence has extensive Indigenous Peoples engagement and consultation experience from his involvement in multiple energy projects in western Canada. Consultancy GHD has widespread international experience in the design and construction of energy production facilities and is a leader in strategy development for the green hydrogen transition.” Montem’s decision to transition Tent Mountain
to become a renewable energy complex followed separate independent expert studies in 2019 and 2021 which demonstrated the project’s strong viability to host a renewable energy complex which would include: 320 MW Pumped Hydro Energy Storage; 100 MW Green Hydrogen Electrolyser; 100 MW Wind Farm (offsite). Montem said its focus now is to complete the FEED over the next 18 months, culminating in EPC tender evaluation in H1 2023. In parallel, the team will commence the Alberta Electric System Operator (AESO) process to establish a connection to the Alberta electricity transmission system (the grid) which involves a stage gate process. Montem is now working to complete the final configuration design for the pumped storage project, building studies undertaken in 2019 and 2021. This step includes a gap analysis on the design configuration which will provide more detail on the major components of the energy complex and the interconnection to the grid. FEED work will focus on a detailed
geotechnical evaluation, leveraging the existing geotechnical data collected during the Tent Mountain Mine Redevelopment Project Feasibility Study. It will also focus on the detailed site-specific design required for the reservoirs, penstocks and the powerhouse, as well as the routing for the powerlines. Connection to Alberta’s electricity grid is
a project requirement to enable distribution of the power produced by the TM-REX. The interconnection process is managed by AESO and regulated by the Alberta Utilities Commission (AUC). Montem will work with AESO over the next six months to complete Stage 1 of the interconnection process which establishes the project’s scope and plan to connect to the grid. Stage 2 of the interconnection process is the assessment stage which includes completing an engineering study on the interconnection and a facilities design and is expected to be completed by end 2022. Montem will then initiate Stage 3 of the interconnection process which involves preparation of the application to the AUC. GHD is being commissioned to undertake detailed analysis of the Green Hydrogen electrolyser element of the TM-REX. This work will include final site selection and investigate the likely technology Montem will employ at the H2 production facility. GHD have already
identified three potential offtake markets for the Green Hydrogen, and Montem will undertake initial commercial discussions with these potential partners.
Loas PDR Voith to equip Nam Sam 3 project Voith has signed an agreement with SCI E&C JSC Company (a part of the SCI JSC Group in Vietnam) to supply three 52 MW Francis turbine units for the Nam Sam 3 hydropower plant in Xam Tai District, Houaphan Province, Laos PDR. The deal covers complete sets of electromechanical equipment, and technical services for supervision, installation and commissioning. The project has a total capacity is 156MW, and
will provide up to 626GWh of electricity every year. The entire project has a total investment volume of more than US$300 million and is being developed by Nam Sam 3 Power Co., Ltd. a member of Phongsupthavy Group in Laos PDR. A Power Purchase Agreement (PPA) for the output of the Nam Sam 3 hydropower station was signed with EVN (Electricity Vietnam) back in June 2019, with power produced to be transmitted from Laos to Vietnam to support power shortages. The plant is planned to be put into operation in June 2023 and will be connected to the power grid of Vietnam at the 220 kV Nong Cong Station. The Engineering, Procurement and Construction (EPC) scope was assigned to SCI E&C who use Voith Hydro’s technological expertise for the turbines following a long and successful cooperation history. Voith has successfully commissioned the Ca Nan 1 and Ca Nan 2 hydropower projects and will also supply the electromechanical system equipment and technical services to the newly developed Nam Lum 1 (9.2MW), Nam Lum 2 (1 MW) and Nam Xe (24MW) plants.

Simec Atlantis sells hydropower firm
Simec Atlantis Energy Limited has sold it hydropower subsidiary Green Highland Renewables (GHR) for £3 million, with VH Auslandsbeteiligungen GmbH (VHA) acquiring a 90% interest in the company and Mr Alex Reading (General Manager of GHR until 9th December 2021) acquiring the remaining 10% interest. In a statement SAE said the sale of GHR will simplify the structure of SAE, enable management to focus on developing the tidal and power station conversion businesses, and bring in necessary additional funding to support continuing Group operations and the development of key projects. GHR provides a complete range of management, operation and maintenance solutions and services to hydro generation asset owners throughout the UK. It has consented more than 65 hydro schemes, built more than
45 hydro schemes and provides operation and maintenance services for more than 45 hydro schemes in the UK. In 2020, GHR’s pre-tax profit was £796,000 and its net assets as at 30 June 2021 were £2,394,272.
Australia SMEC to deliver concept design for Mount Bold dam upgrade Australian utility SA Water has tasked SMEC to deliver the concept design for important upgrades to Mount Bold Dam – the largest dam in South Australia – enabling the structure to meet the current Australian National Committee on Large Dams (ANCOLD) guidelines. Mount Bold Dam is considered critical infrastructure as it is the largest storage in the region with a total capacity of around 46 billion litres, providing 40% of metropolitan Adelaide’s water supply. The new upgrade will bring Mount Bold Dam in line with current guidelines through strengthening the central arch section of the dam wall by buttressing with mass concrete, and strengthening the existing gravity dam abutment sections with post tensioned anchors through to bedrock. It will also remove the existing spillway gates and need for manual operation, provide a free-flow staged spillway to safely pass the full range of floods, including flood attenuation for frequent floods, and incorporate an embankment saddle dam to prevent flow over a low-lying section on the reservoir rim. Ultimately the upgrade will strengthen the
dam to safely pass flood and seismic events, while also providing limited flood protection to the downstream community. “We are proud to be chosen as the project’s concept designer,” commented SMEC project Design Manager Francisco Lopez. “This is a crucial role helping to safeguard one of the Adelaide community’s most important infrastructure assets. A lot has changed since the dam was first constructed in 1938 and upgraded in the 1960s, which means there is a need to reassess and upgrade Mount Bold Dam to meet current ANCOLD guidelines and industry standards. For instance, the capacity to withstand the probable maximum flood and seismic loadings are the two key areas which will be addressed during the concept design phase.” Constructed between 1932 and 1938, Mount Bold Dam was designed and built as a water supply dam with the purpose of maximising storage levels. The dam is a critical and cost- effective water supply asset while also providing some flood mitigation benefits to downstream communities through controlled releases of water. Water is also pumped into Mt Bold Dam from the River Murray. SA Water anticipates that detailed design of the upgrade will be started and completed in 2022. Construction is planned to commence in 2023 and take approximately three and a half years to four years to construct, delivering a more secure and safe asset for the future.
