JUST TO CLARIFY THINGS ON THE SUBJECT OF ELECTRICITY. TO CORRECT MISINFORMATION, PERHAPS MISUNDERTANDING AND IGNORANCE (DELIBERATLY?) BY THE WRITER OF THESE COMMENTS.
"Tendo isto em conta, o Fiji produziu no ano de 2003 - 550 Gigawatts de energia elétrica".
You are wrong! FIRST OF ALL GWh IS NOT THE SAME AS OR EQUAL TO GW!! AS WELL AS MWh IS DIFERENT FROM MW.
Fiji produced 550 GWh which equivalent to ENERGY coming from 62.78388 or 62.8 MW of their electricical power plants. If the assumption of their power plants, sourced from FOSSIL FUEL 20% and HYDRO 80 %, running at 100% during a whole year.
But if their power plants run 80% of the time, that means the capacity to generate power is 78.571429 or 78.6 MW. So in fact the generating capacity of Fiji power plants to produce electricity is between 62 to 79 MW. NOT 550 GW!
Now it's different matter if you say they have power plants that produced 62 - 79 MW of electricity with an energy output of 550 GWh in a whole year.
"Ou seja Fiji já produzia há 8 anos atrás o equivalente a 550 mil Megawatts de energia elétrica comparado com as 800 mil Megawatts proposta para Timor até ao ano 2020".
Fiji actually just has the capability to produce electricity from 62-79 MW of power plants. While Xanana wants Timor Leste to have 8 GW (not GWh) of electricity producing capability by 2020. Two different matters here.
So your example on Fiji in comparison Timor Leste is misleading and irrelevant.
NEXT TIME DO MORE RESEARCH BEFORE COMING HERE TO LECTURE OTHERS ABOUT SOMETHING THAT YOU DON'T FULLY MASTERED AND TO PREVENT SHOWING THE READERS OF THIS BLOG ABOUT YOUR LACK OF UNDERSTANDING ON THE SUBJECT!
"Fiji consumiu 512 dos 550 mil Megawatts produzidos e não importou ou exportou qualquer parte da mesma".
NOPE.... Fiji consumed 512 GWh of 550 GWh from their power plants electricity producing capability of 62 - 79 MW not 55o GW at stated in the first comments.
BELOW ARE SOME LESSONS AND BASIC MATHEMATICAL FORMULA ON THE UNITS FOR YOU AND YOUR BOSS AND EXPERTS IN AMP TO LEARN. MAKE SURE TO DIVIDE OR MULTIPLY THINGS PROPERLY BEFORE YOU COME UP WITH MORE BULLSHITS NEXT TIME..OK? ^_^
Follow my lecture now dear AMP donkeys :
MWh is a unit of energy whereas, MW is a unit of power. Energy and power are two words often confusingly interchanged. Energy is the amount of work done, whereas power is the rate of doing work.
One MWh (Mega Watt Hour) is a million watts of power applied over the period of an hour. One MW (Mega Watt) is a million watts. 1 Watt is 1 Joule per second.
To convert MWh to MW, you should divide MWh by the time applied in hours. MWh = MW * Hours, and respectively MW = MWh / Hours
E.g.
Some electrical equipment used 84 MWh is the total energy measured by a electricity meter over 12 hours operation.
What is the power rating of the equipment in MW?
84 MWh / 12 hours = 7 MW
1 MW of electricical Power means different GWh in a year according to how long the power can be used through the year. 1 year = 8760 hours.
So at 100%, a power plant of 1 MW will produce 8760 MWh, ie 8,76 GWh
For instance, with a nuclear power plant that usually runs 80% of the time you have:
1 MW -> 7 GWh in a year
You have approximately the same ratio (a bit more) with a thermal power plant (fossil fuel)
With wind power plant, they usually run 23% of the time in windy areas (due to meterological conditions).
You then have in such a case :
1 MW -> 2 GWh in a year
For solar power it is less and up to areas.
In California, 1 MW -> 1,4 GWh in a year
In Germany, 1 MW -> 0,6 GWh in a year
Electrical power of plants are up to types of plants:
Nuclear & Fuel : around 1000 MW (up to power plant size...)
1 Wind turbine : up to 5 MW
Solar plant (photovoltaic) : up to 20 MW.
Solar plant (other, experimental) : up to 500 MW so far.

What a shame for those who has no idea about the units of the electricity power...... Hhhhh.

...who have...
Lendo bem todos os comentarios parece-me que quem comecou a confusao toda foi o proprio DONKEY Alkatiri porque diz ele nas suas proprias palavras que:
"O plano é extremamente ambicioso e quer a produção, para 2020, de 800 mil megawatts de eletricidade, para um país que tem um milhão de população."
Ora o PED fala de um consumo de 800GWh como ja citei no meu comentario anterior (16 de Julho de 2011 16:55)
Obviamente que o DONKEY Mari Alkatiri confundiu (deliberadamente?) 800GWh de consumo com "producao de 800 mil megawatts de electricidade"
Esta tudo esclarecido.
Tenho muita pena que os timorenses andem as escuras. E que ha aqui muitos iluminados. Voces ja imaginaram se desse luz as costas do kuda burro? Estariamos na presenca de um excedentario de burrolectricos ou melhor ainda asnoluzidios.
Se eu fosse capaz de produzir energia electrica pondo em fila indiana tanta burro, seria o mesmo que descobrir a polvora seca.

Aileba,
First of all start quoting your sources. Copying and pasting other people's work and passing it as your own is called plagiarism.
Second, use your explanation to give a lesson to your boss Alkatiri so that he does not confuse MW with MWh.
Now in regards to the great surprise and dismay shown by your boss about Timor expected to consume a yearly total of 8GWh as stated by the PEDN by 2020 (not 8GW power generation facilities as stated by your boss) consider the following:
1- According to the 4th Article Consultation from IMF, in 2010 only 36% of the Timorese population had access to electricity.
2- According to World Bank 90% of the population uses firewood for cooking.
3- Currently the Timorese consume a total of 160GWh of generated electricity yearly.
Now if by 2020 access to electricity extends to 100% of the population (as it should) and consume at the same rate as the current 36% with access to electricity, then the yearly consumption will jump to approx to 480GWh (give or take).
Since most households with access to electricity in Timor use it for little more than a couple of light bulbs for illumination, then a mere doubling of that will raise the total consumption to 960GWh.
If enough of those households aim for better living conditions, say, by adding a few more appliances to their power outlets such as a TV, radio to listen to 'radio maubere', maybe a fridge and an electric stove to save the trees, then we are Timor will be moving into the TWh consumption territory.
The total capacity of Hera-Betano power stations will be 240MW.
According to the formula you plagiarized from you know what source, these 240MW combined facilities can produce approx 2.1TWh a year.
Of course in estimating the total electricity consumption in Timor by 2020 as done previously, the development of new big and power hungry industries were not factored into the equation. For instance, the hospitality industry (hotels, motels, restaurants, etc), refrigeration industry, oil/gas processing industry, etc would easily increase the total amount of electricity consumed to quite a few TWh.
Another point you people seem to be missing about planning, something the ADB failed to consider also when they did the study in 2004.
When you plan for the future it is never clever to plan based on current consumption rates, specially in Timor where much as to be improved(not good enough to just have 2 light bulbs). i.e just because currently (or in 2004) most households used only 1 or 2 light bulbs, its not smart to plan just enough for the same usage, for the rest of the population, without considering that people actually tend to consume more as their living conditions improve.
If Timor should strive to achieve better living conditions overall for its people, then its only smart to plan ahead for more consumption rather than less or just enough.
Another thing to keep in mind (maybe you should explain that to your boss) is that a power plant doesn't necessarily need to operate at full capacity at all times. Power generation can be scaled down or up according to demand thus avoiding waist or shortages.
It is not like your boss says "what are we going to do with the rest we don't use?"
There is no need to be a lot of 'rest' and if there is it can actually be sold elsewhere.
Now run and explain this to your mob.
"According to the formula you plagiarized from you know what source, these 240MW combined facilities can produce approx 2.1TWh a year".
If this is the case, what is the point of 800 GWh by 2020?
If this is the case, what is the point of 800 GWh by 2020?
That's the expected consumption rate since much greater percentage of the population would have access to electricity by as opposed to the current 36% only. More restaurants? More hotels? More appliances used by households? It all adds to the increase.
