Major overhaul planned for Queensland’s largest hydropower plant

ueensland’s largest hydropower station, the 570MW Wivenhoe Pumped Storage Hydroelectric Power Station, will undergo a $14 million overhaul to ensure it continues to produce cleaner, cheaper energy for years to come.

Major maintenance works will start at the Wivenhoe station this month, creating 100 jobs under the Palaszczuk Government’s COVID-19 Economic Recovery Plan. The plant is owned by CleanCo Queensland.

Minister for Energy, Renewables and Hydrogen Mick de Brenni said Wivenhoe was incredibly valuable to the reliability of Queensland’s electricity network. “All our publicly-owned energy generators have worked around the clock to respond to constraints in the network in these last few weeks,” de Brenni said. “When Callide C Power Station went offline in May, we were able to ramp Wivenhoe up to the point it was generating 530 megawatts over a four-hour period, helping to meet demand and stabilize the network. Never has it been more important to invest in fast ramping, flexible energy generation and storage solutions.”

De Brenni said the upgrades were critical for preserving the ongoing reliability of the plant. “Here in Queensland, we not only own our energy assets, but we invest in them significantly,” he said. “The Palaszczuk Government’s record energy budget includes $2.38 billion in job-creating capital upgrades and maintenance of our publicly-owned assets. This $14 million overhaul will include the repair and refurbishment of one of the 285MW turbines, corrosion protection painting of machinery and pipes, and repairs to a transformer.

Water Turbine Design for Small Scale Hydro Energy

https://www.boland-hydroturbine.com/ Selecting the Best Type of Water Turbine Design Selecting the best type of water turbine design for your particular situation often depends on the amount of head and flow rate that is available at your particular location and whether it is at the side of a river or stream, or the water is to be channelled or piped directly to your location. Other factors include whether you want an enclosed “reaction turbine design” such as the Francis turbine or an open “impulse turbine design”, such as the Pelton turbine as well as the speed of rotation of your proposed electrical generator. By analysing all of these factors together you can get some indication of what type of Water Turbine Design may work best for your particular situation. Knowing the difference between a Pelton and Francis turbine for example, will help make the choice easier. The following table gives a basic idea of which particul

Types of Hydropower Plants

There are three types of hydropower facilities: impoundment, diversion, and pumped storage. Some hydropower plants use dams and some do not. The images below show both types of hydropower plants. MPOUNDMENT The most common type of hydroelectric power plant is an impoundment facility. An impoundment facility, typically a large hydropower system, uses a dam to store river water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity. The water may be released either to meet changing electricity needs or to maintain a constant reservoir level. www.boland-hydroturbine.com DIVERSION A diversion, sometimes called run-of-river, facility channels a portion of a river through a canal or penstock. It may not require the use of a dam. PUMPED STORAGE Another type of hydropower called pumped

Hydropower, the only solution for cheapest power generation

https://www.boland-hydroturbine.com/ Hydropower has the lowest life-cycle cost of any power generation technology. Hydropower is a potential life-saver for Pakistan. Yet its development has been hampered for decades. Hence, only 15 percent of Pakistan’s over 60,000MW hydropower potential has been developed in 70 years. Hydropower plants power generation can give a country economy a new path of progress. Despite initial costs and long gestation periods, hydropower plants have almost no fuel cost and have operational lives of over a century. New hydropwer plants generate electricity at Rs6-10 per unit compared to thermal power plants’ Rs15-25 per unit. All other power-generating technologies have up to 30 years of project life and need up to four times expensive plant replacements in foreign exchange. Wind and solar technologies are solely dependent on the weather. They can at best supplement but not replace hydropower which, amo
