replaced, with the first new turbine scheduled to come online in 2024. The replacement turbines will be designed using modern engineering and manufacturing techniques resulting in more efficient use of the existing water flows, delivering an additional 44GWh of energy in an average hydrology year. “While a turbine replacement project isn’t as grand as a new build, we are constantly looking for ways to demonstrate operational excellence and improve our generation efficiency. We want to make the best use of the precious taonga we are responsible for,” explained Contact CEO Mike Fuge. “We expect Voith will supplement its international experts with local construction workers and NZ based contractors, which is positive news for the local Alexandra and Roxburgh communities. Projects like these will have real, tangible benefits for our local communities.”
Fuge said the original turbines have performed “extremely well” for 70-year- old technology, and have provided clean, renewable electricity for New Zealand since the 1950s. Stephen Lewis, President and CEO
of Voith Hydro APAC, said that Voith Hydro is honoured to be associated with the efficiency and performance improvement of the turbines at the historic Roxburgh Power Station. The project will be executed in collaboration between Voith Hydro Engineering centres in US, Germany and India and the new turbines shall be manufactured at Voith Hydro’s manufacturing facility in Vadodara (India). The site works will be supplemented by local construction workers from a New Zealand based subcontractor.
Once the design, scale model testing, and fabrication are completed by Voith Hydro, the turbines will be shipped to New Zealand. Contact expects the first unit to arrive in 2023. Each turbine requires approximately six months of installation and commissioning work before it begins operation.

AFDB approves funds for Kinguélé Aval hydro project, Gabon The first independent hydropower project in Gabon is set to benefit from a €39 million loan package from the African Development Bank Group. The funds, which are comprised of €20 million from the African Development Bank, €10 million from the Africa Growing Together Fund and €9 million in concessional financing from the Sustainable Energy Fund for Africa, will be used to help build the 34.1MW Kinguélé Aval hydroelectric project. Additional financing to meet the project’s €133.8 million budget will come from the International Finance Corporation of

the World Bank Group, the Canada-IFC Program for Renewable Energy in Africa, the Development Bank of Southern Africa and the Emerging Africa Infrastructure Development Fund. The loan funds will be disbursed to Asonha Énergie S.A., a company created to manage the project. The project entails the design, construction, and operation of the plant with a net annual generation of 203GWh. The Kinguélé Aval dam will be built on the Mbei River, 90km east of Gabon’s capital, Libreville, downstream from the Tchimbélé (69MW) and Kinguélé upstream (58MW) hydroelectric plants. “We are delighted to support the first IPP
project in Gabon”, said Mr. Wale Shonibare, Director of the Energy Financial Solutions, Policy and Regulation Department at the African Development Bank. “Kinguélé Aval is a showcase project, and the success of the model provides a useful template for future projects that will help move the country closer towards achieving the government’s 100% clean energy target.” “Kinguélé Aval epitomizes the catalytic effect of SEFA and co-financing from the likes of the Africa Growing Together Fund that the Africa Development Bank brings forth to support developers deliver sustainable renewable projects that aid Africa’s energy transition,”added Dr Kevin Kariuki, Vice-President of Power, Energy, Climate and Green Growth at the African Development Bank.

New concept developed for power generation and fluid transfer – named New Hope New Hope – an abbreviation for New Heights Of Physics & Energy – has been developed as an innovative concept for power generation and fluid transfer. The system is a mechanical device designed to harness gravitational and centripetal or centrifugal forces with minimal input from an external source, for example, input can be an electric motor, hydro, wind, biofuels, solar panels and so on. The external source of input initiates the primary mover (rotating mass) and the reaction of the rotating mass activates the gravitational, centripetal and or centrifugal forces. As the velocity of the rotating mass is increased the centrifugal force is amplified exponentially. Initiation of New Hope can be with many
alternative inputs as the developer says the energy extrapolated from New Hope is applicable for almost any application(s). The extrapolated energy can be determined as desired, I, e electrical or mechanical output from New Hope. In order to operate New Hope in a perfect harmony is to loop the system. This will be possible with one of the following examples.
A prop shaft with an impeller is connected to New Hope; the impeller is driven by the water flowing down stream. New Hope can pump the water back upstream with greater efficiency than required to drive it in the first instance. Computer simulations were conducted by a German company to clarify and validate kinematic locks are not prevalent in the mechanism of New Hope. This was followed by the construction of a proof of concept prototype to fathom out any further discrepancies and doubts. It took fourteen years to construct five prototypes to establish the optimum positions and locations of the components and their performances. The first prototype was made partially
from wood and metal parts and a rubber pipe, as the track for the rotating steel ball, approximately 11/12 years ago. The second and third followed within eighteen months of the first one, all construction from here on was from different grades of steel, according to the loads and stresses the developer speculated. The fourth was the most robust and efficient of the four prototypes constructed, with immense variability to change/on-demand the speeds and load of the rotating mass, this equates to output forces dictated by the speed and load of New Hope.
New Hope will generate electrical and mechanical power for many sectors and diverse applications. Also transfer fluids with exceptional efficiency, especially pumping water from source, I, e from the ground, river or sea then desalinate and distribute whilst generating electricity, all at the same time. The rotating mass in New Hope is initiated with an electrical input, causing changes in and around the conditions of the oscillating disc, resulting in a downward slope, permitting the mass to accelerate under the influence of gravity and momentum. Once the inertia within New Hope is overcome, the momentum of the rotating mass continues to generate drag greater than the input; compelling evidence of the above mentioned is highlighted in the measurements taken with calibrated Zes Zimmer precision power analyser. Scalability of New Hope is tremendously
vast, from a few Kilowatts to a few Megawatts output at this stage. Theoretical assumptions and calculations for the very large system has not been compiled or considered because some components need to be designed especially for New Hope that are suitable for the load bearing capacity. The UK and USA patents are granted,
European is pending. The developer is seeking a commercial partner(s) to manufacture and market the New Hope product.
