Kleinschmidt to work on Hood Canal Bridge fish passage project Long Live the Kings (LLTK), a US-based non-profit salmon recovery organization, has selected Kleinschmidt Associates to provide engineering services as part of the Hood Canal Bridge Fish Passage Project. Kleinschmidt will be involved in Phase 4 of this ongoing project to provide fish guidance structures on a floating bridge located on the Hood Canal in Washington stat. The fish guidance structures will be used as part of a study program to determine if fish passage can be improved at the bridge, which currently sees a mortality rate of approximately 50% for out-migrating juvenile steelhead salmon. During this phase, LLTK has requested that Kleinschmidt finish the design effort, produce a for-bid set of plans and special provisions for the fish guidance structure developed, and provide bidding support. “This is a unique and challenging project
from a biological and engineering standpoint. Although this is still in the assessment and testing phase, the project has the potential to make a huge impact in the region in the future,” said Brad Johnson, P.E., S.E. Kleinschmidt’s project manager. “Up to 50% of juvenile steelhead that makes
it to the bridge will not survive beyond it, and other salmon species are also impacted,” added Jacques White, executive director of Long Live the Kings. “This mortality rate is approximately the same as all eight dams and reservoirs on the Lower Snake and Columbia Rivers combined, making this one of the most significant barriers to recovering threatened Hood Canal salmon and steelhead.” The project began in May 2022, with an estimated completion date of June 2023.

Nenggiri project breaks ground in Malaysia
Construction work has begun on the 300MW Nenggiri hydroelectric project in Malaysia, with the official groundbreaking ceremony having taken place in mid June. The ceremony, on 12 June, was attended by high-ranking delegations from government and industry as well as by the customer and owner, Tenaga Nasional Berhad (TNB), and members from the Andritz-led consortium that are supplying the electromechanical and hydromechanical equipment. With commissioning expected by mid-2026, the Nenggiri Hydroelectric plant will provide peak load coverage to stabilize the national

grid as well as flood mitigation benefits for the downstream areas. At the peak of the construction work, it will provide about 2,000 job opportunities to the local people and the possibility of developing further spin-off jobs in tourism and agriculture. Once completed, the Nenggiri dam will generate approximately 600 GWh of renewable energy annually. This project is part of several government-approved projects to meet the growing energy demand in Malaysia and increase the share of renewable energy in the country’s energy mix to 40% by 2035. It is the largest single renewable energy project currently being implemented in Malaysia by TNB The Andritz scope of supply for the project includes two Francis-type turbine-generating units as well as the complete mechanical and electrical balance of plant, the hydromechanical equipment, and the high-voltage switchyard.
Switzerland Hydro to power Swiss Steel Group plant Swiss Steel Group’s Steeltec plant located in Emmenbrücke is to use hydropower from Axpo Holding to power its steel production, marking another milestone on the company’s road to decarbonization. The steel industry distinguishes between two
production routes, the primary and secondary route, respectively, using the blast furnace and the electric arc furnace route. In a blast furnace route, mined iron ore is melted into pig iron and ultimately into steel. This process produces new steel of the highest quality grades, often with very high CO2
emissions. The secondary route with the electric arc furnace works exclusively
with steel scrap and thus emits much less CO2 than the primary route and thus the main source of energy is electricity. The Swiss Steel Group has decided to pursue the electric arc route exclusively in its steel mills. Owing to the use of scrap, decarbonized energy and a functioning cyclic economy, the Group’s emissions are around 78% below the industry average. The ecological footprint of the Emmenbrücke plant is the lowest within Swiss Steel Group. In
2020, the steel mill only emitted 63 kg of CO2 per ton of crude steel produced in scopes 1 and 2. In switching to electricity provided by Swiss hydropower, Steeltec is using not just local energy, but also lowering its numbers further Under the terms of the new contract, Axpo will supply the steel mill in Emmenbrücke until 2024 with electricity certifiably generated at hydropower stations belonging to Axpo’s fleet of Swiss power plants and at a contractually agreed price. “We are proud today to be able to offer our
customers steel melted exclusively with the use of Swiss hydropower,” said Frank Koch, CEO of Swiss Steel Group AG on the occasion of the switch to green electricity. “We are thus making not only a decisive contribution to the
decarbonization of our industry, but also to a greener, more sustainable society.” Laurent Nanzer, Head of Organization
Switzerland at Axpo, added: “We have seen a strongly growing demand for electricity from hydropower and other renewable energies in Switzerland similar to the trend in the rest of Europe. The awareness of production
processes that have the lowest possible CO2 emissions has increased in many industries. With our long-standing expertise throughout Europe and our innovative customer solutions, also including electricity supply contracts and PPAs, we take a decisive part in facilitating the success of domestic industry’s switching to production that is more environmentally friendly and further reducing CO2
emissions.”
Scotland SAE secures government support for next phase of MeyGen Simec Atlantis Energy (SAE) has secured a Contract for Difference (CfD) for its MeyGen site in Scotland in the latest allocation round from the UK Government, guaranteeing £178.54 (£/ MWh) for 15 years. SAE will work to achieve financial close for
this next phase of the project by 2024 with the operation starting in 2027. “The significance of [the] announcement cannot be downplayed,” commented Graham Reid, CEO of SAE. “We are going to be delivering the world’s first commercial scale tidal array and we now have a clear runaway, with future CfD rounds, to deliver the full c400MW of tidal power generation at MeyGen. I can’t thank enough all those who have championed, supported, and invested in our business to achieve this milestone. Our absolute focus will be on the delivery of this project.” The Contracts for Difference (CfD) scheme is the UK government’s main mechanism for supporting low-carbon electricity generation. CfDs incentivise investment in renewable energy by providing developers of projects with high upfront costs and long lifetimes with direct protection from volatile wholesale prices, and they protect consumers from paying increased support costs when electricity prices are high.
India
GE commissions Bajoli Holi hydropower project GE Renewable Energy’s Hydropower business has officially commissioned the 180MW Bajoli Holi Project on the river Ravi in the Chamba district of Himachal Pradesh in northern India, with the project’s three 60MW turbines already generating electricity and supplying power to Delhi’s Indira Gandhi International Airport – the first in India to run entirely on hydro and solar power. The completion of this project is seen as a
big step towards utilising the power potential of the state to support both Himachal Pradesh and the entire northern region of India. In addition to
