Wata just included a new post about wind turbines that caught my attention. Here’s the full write up (link from Wata’s blog).
What I find interesting is that Malaysia is moving towards using its natural resources. Wind is not particularly good in Malaysia as compared to the UK or Denmark, but islands like Perhentian can definitely gain a lot from this new installations(especially when it is jointly equipped with solar panels – which our country is rich in). Also, touching about technical issues, I presume these turbines are not connected to the main grid; eliminating the messy-ness that a typical wind turbine can cause the grid. By messy-ness I mean fluctuation and unpredictability which requires a lot of back-up generation. Since it was previously fueled by diesel generators, these provide excellent back-up when needed and when not needed, we save a lot on fuel cost!
It’s good that we started small(at only a combined capacity of 650kW). It might be optimal to spread out these small devices to capture the resources form different angles and points on the island. However, we should also bear in mind that when other countries are moving towards 2MW and 5MW single wind turbines, we should do the same and beneft from economies of scale – in terms of having less number of generators, gearbox, installation space and maintenance cost as well as providing additional capacity. These additional capacity if found to be more than needed, should be stored by the various means available(although it is a bit expensive at the moment).

you know I am now writing about wind turbine. It will be on my next post. haha… what a nice coincident.
sohas // 1 August 2008 at 4:46 pm |
that’s good – looking forward to that post!
Viknesh // 2 August 2008 at 12:08 pm |
actually its such a shame that Malaysia has not been able to exploit our geographical position to utilize solar energy. we practically have sun all year round.
is it still as expensive as before?
Relax // 2 August 2008 at 6:20 pm |
@Viknesh
yes it is, unless we can get some Nanosolar’s goodies.
I blogged about green technology today.
sohas // 3 August 2008 at 10:58 pm |
Solar is still very expensive to produce and compete with gas/diesel/oil source electricity generation. This is because storage systems have not developed that much(not cheap as well). Plus, we need extra management of the network if they were to export excess electricity into the network.
Radzian // 4 August 2008 at 12:19 pm |
For wind turbine project, TNBR (a subsidiary or department) within TNB has researched and implemented it on one of the remote island. The project leader was Hj. Zamani.
Wind turbine is costly comparable with hydro and fossil fuel.
I fancy solar more but you know the cost.
We are back to basic – “hydro” and if Bakun was not cancelled, it would have been great. But at that time nobody knows fuel will be this expensive. Now, even the cost of Bakun has increased.
Another source being looked at is nuclear. All in all, safety issue should come first.
sohas // 4 August 2008 at 1:39 pm |
We have signed some treaty for not using nuclear, from what I recall. However, I think nuclear is a good source of energy, if well managed. Given that we do not have the expertise, this might also be an expensive source of energy; making it not very attractive. Plus it takes along time to build and commission(circa 10 years).
Hydro was a good plan – although costly. The value we get from a fast start-up is really good for reliability. Given that the resource(water) is free, in the long term, only O&M costs exists whereas capital cost can be paid back over the long years that this project will be operational.
I do not see why we cannot harness ocean energy, via tidal and wave sources in the future. Yes, it is expensive now – but, being surrounded by sea, Malaysia has good resource that can be used. I do not see any initiative towards that front. Any info on this?
radzian // 4 August 2008 at 5:07 pm |
Tidal, simply untried.
Wind – tried but not feasible.(Cost too high). Seems the project stopped.
Solar – tried but not feasible. (Cost too high). People are still working on it.
DG@Biomass future good area . Tried. Result quite encouraging.
Nuclear is one of the new initiatives. As it is for me, safety must always come first.
sohas // 4 August 2008 at 5:11 pm |
Tidal and wave are still too expensive,but I believe that the government should subsidise it. Same goes for solar – the government has to subsidise in order for large scale projects to take off. The German government pumped in a lot of money to make solar power a success in Germany. In Malaysia, less would be required for the same output, given the number of hours of sunlight available. We need people to plan for the future – now is the time to do that, not when fossil fuel runs out.
Biomass is certainly good and Malaysia has progressed on that aspect!
radzian // 4 August 2008 at 5:29 pm |
For Malaysia , biomass progress is still quite slow. Brazil is a showcase for biofuel.
Nuclear – at the moment headed by a person whom I know – Dr. Zam Zam. Malaysia in fact has more than 100 nuclear doctorates. But for a first timer, better becarefu, l right.
Solar – how I wish. Government do subsidize . But I did calculation, unless one is in love with green energy, then they wont think much about the cost benifit calculation for cost given by Pusat Tenaga Malaysia. Wonder whether public can get panel cheaper than quoted by PTM ?
BTW sohas – where do you work at b4 doing ur doctorate ?
sohas // 4 August 2008 at 5:41 pm |
Interesting to know about our nuclear expertise – thanks for the info.
In order for all these to progress(renewables), awareness is key – educating the public is a must. Now, the major barrier as we all know is that people are not willing to spend more for renewables as they cannot afford it. Standard of living needs to be improved before we can even think of this.
I did not work before Radzian, just got my Master of Engineering(MEng) last year and jumped into this…how about yourself? You seem to have a lot of experience.
Radzian // 5 August 2008 at 2:03 am |
I did my B.Eng in 1995 , then worked in TNB. Did my MBA in 2002 part time basis , got married and now doing my PhD.
Working experience I have some but I think the best part of knowledge that can be applied to real world do come from MBA because the professors pushed me to read 20 journals per semester, tough but very rewarding.
sohas // 5 August 2008 at 3:14 pm |
How was working with TNB? Which division were you involved in? And are you gonna join TNB after your doctorate?
I thought generally people don’t do a phd after getting an MBA. hehehe. But it must be really good – where did u do your MBA?
Radzian // 6 August 2008 at 4:42 am |
Working with TNB ? Salary is low, increment is slow.
I did my MBA because I was sent to do management role of a district. I guess needing knowledge led me to self-fulfilment. Even I can detect if my superior lied to me. Wink
I do my PhD because I think it is going to be rewarding in the future (in the sense of many new universities and Malaysia infancy state of research and development) and there are not many PhD(Eng) having an MBA around , right ?
MBA – did it in MMU (Multimedia University). I guess the Ex President of MMU – Prof. Gauth Jassmon has placed structures that enabled me to study in the weekend without letting down my family members. That is the reason why I chose MMU.
Nevertheless, the lecturers and knowledge do not let me down. There are some good lecturers from India work there – such as Prof. Seetharaman and Prof. LVLN Sharma and occasionally they do invite lecturers from good Indian university such as Hydrabad Institute of Management.
sohas // 6 August 2008 at 4:04 pm |
Sounds good. I would imagine so in TNB – hopefully they change.
What is your opinion about the electricity market in Malaysia? Would you prefer a liberalised one or the current monopoly?
Radzian // 7 August 2008 at 2:22 am |
Malaysia’s ESI is not a 100% monopoly.
The generation business segment is an oligopoly with long term contracts. However a long term contract means it is not traded like a “free market”.
In my MBA Thesis, I have summarised the different structures of ESI and it’s pro and contra.My personal opinion, I neither prefer a 100% liberalised or 100% monopoly. Both type of structures is prone to abuse.
However current oligopoly structures is not good as well because it has actually increased the cost , instead of reduce it because the IPP need to make profit.
I prefer future IPP to be constructred based on open tender basis (of which TNB is allowed to participate in the tender) with a certain percentage of supply capacity is contracted for long term to ensure stability of the generation market.
And the remaining supply capacity produced by the IPP is preferably offered to sell to TNB on the basis of “free market”, competing with other IPPs and TNB’s power producer.
sohas // 7 August 2008 at 8:51 am |
Well, only the generation bit is sort of ‘open’ to IPPs. I agree with you regarding the tender basis being a better solution than the current arrangement. But, I think they should trade freely; hence the price they get would be based on the market created; rather than fixed contracts making it more transparent.
Also, TNB is the only supplier available and consumers are not given the choice of tariff to adopt. This needs to change in order to influence consumers’ behaviour. For example, Time of Use tariff – so people might choose to use electricity at off-pak times instead – saving them money, and reducing the peak demand;hence saving on capacity and congestion of the network.
Radzian // 7 August 2008 at 3:12 pm |
FYI, offpeak tariff is available in Malaysia for large power consumer. It is not extended to domestic consumer because domestic being domestic does not use electricity at night.
Influence consumer behaviour is a term but sometimes the reality of competitive forces can make consumer become angry lot. Oligopolist can work hand in hand in demonising the consumer by establishing a “cartel”.
It is hard to liberalise distribution segment in Malaysia. TNB and government have done a pilot case project on this matter in Malaysia, the company has failed. Many have talked about it. I know many reasons why a distribution company can fail under a free market, believe me , I was a manager before.
We tend to believe in free market . However, evidences exist that free market is not 100% free. Free market without considering structures and policies can lead to failure. Many potential issues 1) cross-subsidization, 2) reliability, 3) even the policy maker could make policy that victimise certain companies, if not the consumers.
It is actually the free market that was not truly free that kills Distribution companies during the California Energy Crisis. Again this is an issue of structure and policy.
How can we sure that everything has been looked into in a free market ?
If one can not be that sure, then personally I think “a hybrid” is better – Big to medium percentage of supply under long term contract and small percentage in free market. Once confidence has been build , simulation can ibe done based on available data – the percentage can be changed based on optimization of objectives – reliability and cost.
Just a 2 cent thought.
Off-peak time tariff exists for industrial consumer.
sohas // 7 August 2008 at 3:19 pm |
Off course it makes sense to charge different rates for larger consumers than domestic ones. But you see, this flat tariff at domestic level does not give consumers ways in which they can save(by shifting their usage) – although small, large number of houses can contribute a certain percentage in load shift.
I have to agree that a hybrid model is better than a completely free one. But, how about a regulated one – this would ensure that the government allows open competition but monitors revenue/income of this distribution systems/transmissions systems operator. By imposing price-cap or rev-cap, this can be done somehow.
However, I do agree with you that we should take it slowly – go hybrid, evaluate the case and alter as needed.
What about interconnection with Thailand and Singapore? Do we have that?
Radzian // 7 August 2008 at 4:38 pm |
Domestic consumer of Malaysia, all of them if they act together can shift approximately 18% of load.
But I could not imagine people switch off air-cond at noon and switch on air-cond at midnight. or delay watching news at 8.30 pm so that can save by watching midnight news… possible but most people sleep at 10 pm nowadays to get to public transport early because they cant afford to pay for petrol.
Usage of off-peak tariff is made possible by “District Cooling System” or having energy storage system to store energy during night and use it in daytime. But for it to be cost feasible, one need a usage of 6Mw per month. Even at that. the ROI of District Cooling System is only 4% per annum. More practical usage is for factory, by having night shift operation.
I have written about problem of a free market system. Problem can also happen in regulated system such as one which is monopoly. The revenue can be high but the cost can be high. An example, general manager in a monopoly may opt to buy expensive – a RM 1,000,000 price of carpet for his office where the carpet can be bought for RM 50,000.00. They know the revenue is there and there know they can spend.
Regulated with many competing companies may be good. The question, what is the (1) efficiency of the regulator and (2) what sort of regulation is in place. Regulator has to make swift and fast decision, changing with time (price cap and re-cap) which means only looking at account is not sufficient. In the case above, regulator should behave like operation personal not one that can sit back waiting for financial report to decide. I base this opinion on California Energy Crisis
Some journals say that California is a liberalised free market. Actual fact is that it is semi liberalised. Generation segment sell electricity to Distribution at a fluctuating “market” price.
However, distribution price to consumer was capped.
In a cartel-like operation , generation price increased tremendously above consumer price and a few distribution companies were filed for bankruptcy.
The distribution companies which were not bankrupted simply refuse to sell electricity to consumer because they know that they will make abundant of losses. This concludes a “Blackout” for days, if not for a week.
That is the most reason, why I feel and think that to speak only about free market, or monopoly or regulated is quite dangerous if we dont properly design the structure, processes and policies/regulations.
We do have HVDC with Thailand and interconnection with Sg. The last I heard is a line with Indonesia.
sohas // 10 August 2008 at 2:31 am |
Line with Indonesia – kalimantan or nearer to peninsular(sumatra, jawa etc)?
Talking about load-shifting, I wasn’t refering to air-conditioning – more towards usage of washing machine for example. However, I agree that the figure is pretty small. Storage is definitely key and people are trying to improve the storage density whilst reduce cost. But I guess it will takes many years before it becomes realisable.
sohas // 11 August 2008 at 4:23 pm |

Radzian // 13 August 2008 at 1:42 pm |
Been busy lately to comment.
Line with Indonesia i.e. Sumatra and Kalimantan.
I think that you are concern about the environment situation in Sarawak. My opinion. when I look at the location of the hydro dams, the source are strategically and evenly distributed along the region. means that it is well planned in term of reliability. Perhaps it may allow a n-1 system , and can be supplied through a feedback when one line is down. I think Sarawak will have good reliability by 2020. Do you know the planner of the system ?
sohas // 13 August 2008 at 2:09 pm |
Well, I support the building of hydro dams – but hope that the environment would be be very damaged in the process. Hydro is definitely good for reliability with fast reserve/start.
I don’t know about the planner – even if I know the name, I would not know them(previous achievements, company structure etc).
Radzian // 14 August 2008 at 4:26 am |
I am too concerned about the environment and I think engineers should think about the solution of it.
A few things that I can thought off:-
a) Ensure increase of work ethics and professionalism in carrying out the construction of hydro dam.
b) Rebuilding of habitats of animals surrounding the dam.
c) Having a policy of replanting equal number of trees elsewhere for number of trees pillaged due to building of the dam.
It also opens up an area of engineering work :-
a) Reliability and equipment assessment of hydro plant .
b) Risk assessment and simulation, Safety Analysis, and Contigency Planning in scenario of “Dam Break” .
sohas // 14 August 2008 at 2:18 pm |
I think those are brilliant suggestions
1) Increasing ethic is vital – it’s lacking in Malaysia and developing/under-developed nations at the moment. Regulations need to be put in place in order for this to materialise.
2) Replanting trees are theoretically encouraged, but not effectively done in practice. Again, those with approval to build the dams must also have a clause saying they must do this and preserve the area.
3) The area around the dams can also be developed to encouraged tourism – e.g having a walking path, cycling path and even tour guides around that area. With proper tour guides explaining about nature, people are more aware and HOPEFULLY act responsibly.
Regarding the opening of these engineering area, aren’t these already in place? I don’t know about it, but I would think it is necessary for the existence of contingency plans.
Radzian // 18 August 2008 at 5:21 pm |
During my time in TNBR , there are some undergoing research.
In these areas, results tend to have uncertainties and it means there are some work to be solved, sensors to be tried out , analysis to be made and system to be built. A lot of soft computing method that could be tried on these and a lot of different way in analysing them.
It open up a whole lot of area.
sohas // 20 August 2008 at 6:14 pm |
That is very interesting. Hopefully they’ve made some progress. However, because of the limited number of hydro powered stations around, the scope for job is limited. Would it not create sort of a monopoly/oligopoly in skill set/companies doing this?
zairizain // 14 October 2008 at 3:34 am |
i’m going to do some research about prospects of offshore wind energy in East Coast of Malaysia. any opinions or suggestions?thanks
sohas // 14 October 2008 at 9:08 am |
That sounds interesting. Are you gonna do some real time measurement and analysis? That would be awesome. Few things to consider:
1. Potential for wind harnessing(size of turbine and farm), how far offshore and what are the costs
2. Connection cables – using AC or HVDC? HVDC seems to be the way forward here – but check the costs and feasibility.
3. How much support does the government give in their policies?
Are you doing it for work or for studies? Sounds cool….
Fadzli // 25 October 2008 at 3:19 am |
Maybe you forget 1 more parameter..
the height ( H)…and tnbr engineer can start experimental project from the top of male cendiakiawan apartment at 10 th floor…or twin tower..until today,the most evil enemy for hydro generation including Keplan type are “water hammer effect”…maybe its time the tnb engineer n REMACO guys show their ability since tnb running lost for efficency and maintenance..For contingency plans,pls refer to Majlis Keselamatan Negara (MKN) issued and sign by Tun Dr Mahathir ..I believe TNB generation had study already and provide Env Impact Assmtent (EIA) and Detail Env impct Assmt (DEIA) to dptemnt of env (DOE) and execute env audit continuously in term of to protect env..Anyway, I agreeed with nuke as alternative energy for malaysia.
Amir // 29 November 2008 at 2:00 pm |
May I know what kind of solar technology that the government/TNB are planning to implement for alternative electricity generation in Malaysia? Only photovoltaics or solar thermal or maybe both?
TSeong // 6 December 2008 at 10:32 pm |
I think wind power in the east coast is a great idea. Feasibility should be quite good as there are already wind energy projects going on in Vietnam and the Philipines. But of course it’s important to study the real resources that’s available to identify potential sites. The Government should really consider the potential of wind energy.
sohas // 7 December 2008 at 3:58 am |
Amir: I am not aware of the kinds used – will look into it when I have the time over this christmas
TSeong: I agree with you – feasibility and cost benefit analysis muct be undertaken before any rules on policy or investment can be rolled out…
GreenWorks // 16 December 2008 at 9:34 am |
Very interesting thread. Compel to share some thots with regards to wind energy for Malaysia. I had done small research in this area.
Firstly we must understand our wind resource. Being in the equator, our wind is abundant but the wind speed is very low (Class 1 & 2), roughly between 1 m/s to 5 ms/s 70% of the year. Another 15% of the time we will have winds of >5.5 m/s to around 7 to 9 m/s. The other 15% of the time we just dont have wind ( 10 m/s. TNB’s wind turbines (the NorthWind 100 systems) that were installed in Malaysia falls into this class 4 wind speed categories. Sad to say, their wind turbine pilots only generates power during the offshore monsoon winds. Other days, their wind blades idle and their systems depends too much on limited solar system and diesel.
Iam going to test on government funded pilots for small 30kWhr/d wind turbine that works in Class 1 and 2 winds. This turbine starts generation at 1m/s, produce 200watt at 1.5m/s, produce 1500 watt at 4m/s and at 6 to 7 m/s produce 3000 watt. On normal days it could produce 25 to 30 kWhr/d and during monsoon it would bark out more than 45 kWhr/d. One of such turbine could power up one small 10 class rooms schools in the rural and remote site of the country with computers, lights, fans, tv, satellite discs and occasional use of kareoke he he..
Unlike turbine from the rest of the world, this turbine doesnt furl, meaning at the occasional high wind speed (>12 m/s during storms and ribut) it would not ceased generation of power. The tower hub hight for this turbine will be at 40m high in order to be away from surface turbulence that reduced wind speed. If this pilot goes well we may have a cheaper wind energy resources for the country and will definitely help to illuminate the poor rural villages of Sabah and Sarawak. With electricity lifes in the rural will change and economy to this areas will nuture. Unknown to many, this turbine design that I will use for the pilots have already generates wind power for 12 years in the Sarawak (private sites).
Cheers to all and its good to know there are many people like you all are hype for green energy.

Hi all
Regarding Wind Turbine Generator (150kW) project done by TNBR at Layang2 Island , now i’m searching for a company/subsidiaries in Malaysia who able to repair/maintain that ‘project’. Not much i can get from goggle. This source of energy is kind of new technology for Malaysian so i don’t think any Malaysian company has fully knowledge about it.
Some info about that WTG is that it was just used to supply power just to generate fresh water from desalination plant before and never fully utilized becoz of many defects since acceptance .
I had contacted the project manager but sorry to say TNBR is more interested in maintenance contract. I’m not sure if Saudara Radzian also involved on that project.
Pls comment
GreenWorks // 30 December 2008 at 8:20 am |
Thank you for your email Soha, iam replying on your blog as for others to share my updates too. We have made presentations and decision level discussion with the Multimedia Commission of Malaysia and Telekom Malaysia on the potential of using this Low Wind Speed Wind Turbine for their Universal Service Provision projects (broadband, multimedia and communication projects) for the so called ‘0ff-grid’ underserved areas of the rural and remote communities in Sabah and Sarawak.
Pleased to say that the first LWSWT project that we decided will take off the firstquarter of 2009. We have decided to install 5 30kWhr/d WSWT with solar as backup (no diesel power generators), inverters and 2 days of battery storage in Bario, a highland in the rural central Sarawak.
The LWSWT powered renewable energy system will supply 150kWhr/d electricity (24 hrs) to energized 20 personal computers, one VSAT, 3 airconds, 2 cctv camera, and one modem for the Bario Community Broadband Center project (for anybody to use in Bario).
This is a project under USP funds of the Multimedia Commission of Malaysia and they have done hundreds of such projects for the poor and rural community in this country. But this is the first for ‘off-grid’ installation. Following this hundreds more ‘off-grid’ communities will enjoy broadband technology in their remote kampungs. There are about RM 300 million funds that are allocated for this projects in 2009.
Bario is 1 hr flight from Miri, Sarawak and it is a small 30km by 15km plateu on a highland averaging about 3300 feet from the sea level. Thats right, the only way to get to Bario is to board the twin otter propeller once a day flight from Miri together with local Kelabits with their luggage of vegetables, cooking gas and chickens. By roads and rivers it would take two weeks to reach the foot of Bario.
For this project, we planned to conduct site visit to indentify the suitable location for wind turbine sitting some time mid january.
The Kelabits, as I read, is a very nice and friendly indigeneous people of Sarawak. Internationally, they have been made welknown by tourists and ngos that they were once awarded as the Most Intelligent Indigeneous People of the World. In Malaysia, Idris Jala, the MD of MAS is a Kelabit.
Iam very much enthusiast to visit Bario not only because it is my first business with LWSWT, but mostly because of the idea that we could use or harness these abundant winds using these machines and generates zillion hours of electricity for ‘free’. Bario in Kelabits means ‘wind city’. Imagine the Kelabits then could have cheap energy to light their house, watch astro, surf the wwworld, store their cold food and medcine, operates electric sewing machine, runs machine cutters or power drills or solders, squeeze and can their famous sweet Bario pineapples and the most important is to create, make, manufacture anythings as to bring home economic benefits and eventually afford to send more of their young children away to study.
So our plans are so compelling and we should have them on the ground some time march or april.
Time permit, I may give updates and more information about the Kelabits in Bario after my trip….cheers

So great to hear that you are doing wind turbine business in Malaysia, because lot of Malaysian feel that “Malaysia NO Wind for power generation”. I personal think that this is due to they are thinking about the old conventional type HAWT. But look at your statement that your wind turbine can generate power start from 1 m/s. This is much much more better than what i seen on internet. If you don’t mind, please let me know where your wind turbine come from? what is the rated power output and in what wind speed? have you install any unit in Malaysia or elsewhere? really curious about this wind turbine, by bringing this wind turbine into Malaysia, there will be a big step for wind to conquer the market of renewable energy in Malaysia. Hope to hear from you soon.

Dear Greenworks,
We are actually planning a similar task to what you are doing in Sarawak for the Sabahan’s. We are in the midst of acquiring a large piece of land near mengayau to conduct a feasibility study on wind farming as well as agri farming. Your inputs may help us enhance or even disseminate the awareness to the locals. Please advise your thoughts freely.

I was just wondering,
with the landscape that we have even in the semenanjung such as the Sime Darby Plantation for example and every other wind corridor in the cities, wont hurt to have one of couple of those thing there to power up the place.
SUch as having wind turbines in certain city buildings will eventually power up the entire city block using the helical twisted VAWT which not only cause less noise but will also decrease the power expenses for the city blocks and at the same time giving some profits to the buildings that has the wind turbine to supply the power. The UK are doing it in the cityscape, why not us.
Richard Loh // 23 February 2009 at 2:41 am |
Dear En.Nizam,
We are also into Wind Turbine VAWT systems since 31st of July 2008 and we already installed 6 units in varies sites in Malaysia. We are very keen on this Bario site and looking forward to explore further with your goodself. FYI our Wind Turbine can also start up at less than 1m/s.
Looking forward to hear from you soon.
Best Regards

Dear All Wind Energy Enthusiast,
So far i am seeing all those keen to exploit the Malaysia wind energy are only talking about the different specs of wind turbines only but no one seems to understand that the key to identifying or i would dare say forecast the wind movements via professional wind mapping. Most successfully established standalones, hybrids and wind farms are conceptualised & realised only after thorough studies are done and analysed repeatedly i.e. wind mapped areas. Then why isnt’ there any efforts being put forth from our local experts as the task only requires a min of one year’s worth of data. Are we so desperate for accomplishments and monetary fulfillments that we are willing to gamble by setting up machines here and there and hoping to strike a jackpot or two. This is so because without any kind of indications via a professional wind map no one can be so sure that any particular area will be wind friendly 24/7. There are incidences where in one a learned scholar exclaimed that a particular spot at the tip of borneo is so windy that the converted kinetic energy can be supplied for the entire Sabah. However once we reached the said area it was still and calm, not even a breeze was evident. I would not blame the scholar for his knowledge on mechanisms involved in tapping the wind energy is not complete and premature. The victims here will be the community especially in East Malaysia, who will be fed with all sorts of promising developments that will entail but end up with having the contraptions become white elephants. Hence please Sir’s and Madam’s, kindly route your efforts to establish a full fledged professional wind map for our country first before gambling with the various turbines.

Hi,
I would really like to know more about the feasibility of wind energy in Malaysia. My company is currently proposing a feasible green technology for the ministry of energy, green tech and water, in which the investor is interested in wind power. I’m more inclined to ensure that the project proposed is thoroughly researched, and that it benefit the both the country and the government in the long run. Any emails, websites, or contacts regarding the useful information is highly appreciated.
Thanks & Regards
NM
sohas // 26 February 2009 at 7:47 am |
That is a very good point raised by Prakash and Malaysians seem to have this attitude of just jumping in and investing, without sound research and investigation to back it up. Investgation and research do add up to the costs in the short term, but would be beneficial in the long run. Given the current global economic slowdown, every penny spent has a high opportunity cost and we need to ensure that we are positively adding value to the economy and people’s standard of living.
I would like to thank all the visitors and people from the industry for insightful comments and discussion and above all, using my blog as a platform. I look forward to more interesting discussion

I have just read 2 articles regarding to wind energy in Malaysia. The system in National Parks in Sarawak need minimum 4.5 m/s wind to turn. The hybrid (solar, wind and diesel) maximum of 3.5 kW in 24 hours (although the wind rated output itself is 20 kW in Samusan and 5 kW in Tanjung Datu). Unfortunately, due to lightning…..both wind and solar no more working. Now only run on diesel. For Pulau Talang-Talang, the wind part was abandoned due to lack of wind speed…..according to the article. One of this paper…with picture of the wind mill was presented in ICREPQ 2009.

High current inverter – Thermo generator
The range of inverters for various purposes is steadily growing, especially for the photovoltaic industry. The technical development requires new manifold applicable devices.
The patented high-current inverter of unconvetional design, acts as a commutator a reverse the polarity. This is designed for special operations and provides a standard at the exit by the polar reversal of the applied DC voltage periodically a pure rectangular voltage with a given frequency. With filter additives the changed of trapezoidal shape up nearly sinus.
The characteristics of this device are controlled switch components with unusual parameter data used in the professional sector are not really unknown, and is distinguished only by the application of various internal structures of the switch component, then the function result.
The high current inverter, the extremly high values directly into DC current pulses can walk, is very versatile application, it can be DC pulses to be transported long distances and thus reduced the losses to thousands of kilometers, or as an inexpensive control system for battery powered vehicles in the world space and continue to have unprecedented opportunities.
A proven model was robust environmentally friendly, the production is simple and inexpensive.
Taking account of patent law requirements, the functional description and production plans are of significance.

Hi Ken Kiat,
It was Lucas Tan that mentioned the two articles. I did not mention any paper in the original blog article.
