Cardinia Hydroelectricity Plant 2011 Proposal To: The minister of Sustainability, Environment, Water, Population & Communities Tony Burke

Ashleigh Tsui-Po Water Stream Founder & CEO

Summary: Water Stream was established in 2011. The company provides hydroelectricity to government bodies who then supply it to the community. Water Stream provides an alternative form of renewable electricity. Hydroelectricity is produced by the force of flowing water released from a dam or reservoir. Water Stream want’s to create a new hydroelectric plant at Cardinia Reservoir. This form of electricity will minimize the amount to Co2 produce by the current electricity providers.

Statement of Issue: The issue affecting Cardinia is the amount of Co2 their current electricity providers are producing. In Cardinia the main source of energy is produced by coal. This type of energy is releasing large amounts of Co2. In one hour approximately 1.02 tonnes of Co2 is let into the atmosphere from one power plant. This Carbon Dioxide is impacting majorly on Global Warming and needs to be minimized. As you can see from the graph below Australia is the 10th highest country in the world that produces Co2. Australian’s emits a massive 17.74% of the world’s Carbon Dioxide.

Carbon Emissions

Statement of Goals and Objectives: If Cardinia Reservoir was to be used as a Hydroelectricity plant we would be able to:    

Decrease the amount of Co2 we use by approximately 117,333 tonnes per year Power approximately 124,000 homes annually Manager the amount of energy produced by the plant Increase the amount recycling of finite recourses

Description of the project: The plant will consist of 3 generators and turbines where the electricity will be generated. The plant needs a Pipeline sloped on an approximate angle of 20 degrees. Along the Pipeline we need a Control Valve. The Control Valve controls the flow of the water. This is where the water can be stopped or flowing. The pipeline then continues circularly forming a circle. This is where the Water Turbine is positioned in the centre. The Pipeline then continues circularly down to the Tailrace. This is where the water goes out and is recycled back into the reservoir. Above the Turbine is the generator. This is where the electricity is generated from rotations of the turbine, from the force of the flowing water. The electricity is then transferred to the transmission lines. The transmission lines are connected to power lines which distribute the energy. The Generator and Transmission lines need to be enclosed. This is so the water cannot fry the generator and stop the energy from being distributed. The Tailrace will need a sloped pipe connected to it so the water can continue back around into the reservoir. This extra pipe is essential to saving money so we don’t need to build and extra dam and it is crucial that it is sloped.

List of required Resources: These resources will be needed to create the Cardinia Hydroelectricity Plant:          

3 70MW Turbines 1 Pipeline 1 Control Valve 3 Generators 1 Tail race 1 Connection Pipe 3 Transmission lines 1 enclosed box 3 power lines Workers/Builders

Budget: The Cardinia Hydroelectricity plant will cost approximately $320 million dollars. This is a one off free, of this amount. There may be costs in the future for replacements.

Justification and Supporting Evidence:

Bogong Hydroelectric Plant The Bogong Hydroelectricity Project is a $240 million dollar project situated 300km north-east of Melbourne. The 140 MW power plant produces 94,000MW of power per year. This is enough power to power 120,000 homes a year. The plant will reduce the amount of Co2 by 88,000 tonnes annually. The power plant will make a large contribution to meeting the Renewable Energy Target of 20% of renewable energy by 2020.

Warragamba Hydroelectric Plant The Warragamba Hydroelectricity plant is located about 65 km west of Sydney in a narrow gorge on the Warragamba River. The 50MW power plant has 1 turbine. The plant was completed in 1959. It is currently owned and operated by Eraring Energy. When the plant is operational it releases 5,000 mega liters of water a day, which flows into the Nepean River. The water released from the plant cannot be used as drinking water.

Burrinjuck Hydroelectric Plant The Burrinjuck Hydroelectric Plant is located at the bottom of Burrinjuck Dam on the Murrumbidgee River near Yass. The Burrinjuck Hydroelectric Plant started operation in 1927. The plant started with two stations. The first station had two 5MW turbines as well as the second one. In 2001 the second station was upgraded to two 6MW turbines. During this time a 3rd power station was built. This station was built will a single 16MW turbine. The plant is now a 28MW power plant.
