For me, I think this is a really cool exploration. This exploration call Electricity in Cambodia. In this exploration we wanted to know more a lot about electricity in Cambodia and document it on our website, and also we need to know where does the electricity comes from. First, I think electricity came from outside countries like Vietnam and Thailand. But After I learn in this exploration I know a lot about it. Let me tell you what we have learned so far in this exploration. We have divided each other into 4 groups and all of them have work to do, they need to research on any energy source like hydropower, solar, windmill, else
So my team are working on how hydropower work? Let me tell you a bit of information that I know from how it work.
Hydropower create the energy of falling water through the dam. The hydro dam can be constructed anywhere that has a flowing stream of water. There are four main part in hydropower:
Dams are built to store and raise the level of water such as rivers to create flowing water. They can control the flow of water and effectively store the water used to provide energy at any time.
Turbine is a rotary mechanical device that is one of the main components to produce energy. They spin from the motion of falling water and turn it into mechanical energy.
Generator is connected to the turbine. When the turbine spin the generator acts the same. It converts mechanical energy from the turbine into electrical energy.
Transmission lines so after generator create electricity the Transmission lines can make the electricity increase or decrease.
I also know a lot about the generator, so the generator has the magnet around the copper wire. It will create electricity when the copper wire spin around the magnet but if you imagine the generator that we use to create an electricity every day is really really big and we can’t use our force to spin it, so how can we spin that generator. We need to use something to call a Turbine, the turbine are connected to generator so when the Turbine spin the generator is also spin like a turbine too.
There are 7 dams that operating in cambodia
- Kirirom I (12MW) in Kampong Speu
- Kamchay (193MW) in Kampot, which started operating in 2011
- Kirirom III (18MW), which started operating in 2013
- Stung Atai (120MW) in Pursat, which started operating in 2013
- Lower Russei Chrum (338MW) in Koh Kong, which started operating in 2014
- Stung Tatai (246MW) in Koh Kong, which began power production in 2014
- Lower Sesan II (400MW) in Stung Treng province, officially opened in 2018.
All of those 7 Dam mostly the owner is china and just only 2 of them are Cambodia, in one year all of that dam can create about 1327 MW every year but that 1327 MW can’t go to all the people in Cambodia so some people who live off-grid some they need to use a solar panel or wind power. EDC goal is to make all the people in Cambodia be on the grid by 2023.
