New solar and wind power project unveiled

December 26, 2017

Officials from the Ministry of Mines and Energy have announced a new project that will provide a boost to the local renewable energy sector by electrifying three key provinces with the use of small-scale solar and wind power devices.

The provinces of Pursat, Kandal and Mondulkiri will benefit from a new project that will further the government’s goal to provide access to electricity to every village in the country by the year 2020.

Victor Jona, the director-general of the Ministry of Mines and Energy, said the project is now in the preliminary stages. The first feasibility study was recently finished with positive results.

“We want to help people in remote areas gain access to electricity,” Mr Jona said, who also explained that, under the new project, households in the selected provinces will be equipped with small-sized solar panels and wind turbines.

Each solar panel and wind turbine will cost about $200 and can generate up to 60 watts per household, said Mr Jona, who added that the government will help farmers purchase the devices by subsidising half their cost.

“During the first study, it was shown that the project is feasible,” Mr Jona said. “Now we are moving on to phase two, which involves seeking funding from government and other developing partners to implement the project.”

Mr Jona said that 28 megawatts were generated nationwide from home solar electric systems and commercial solar plants in 2017, while only 300 watts were produced through wind turbines.

While more studies need to be conducted on using wind energy for commercial purposes, small wind turbines used in residential applications show as much potential as solar power, Mr Jona said.

In August, a $12.5-million, 10-megawatt solar farm in Svey Rieng province’s Bavet city – the country’s first solar power plant – came into service, selling energy to the national grid under a 20-year power purchase agreement.

$400m solar project launched 

Global Purify Power (GPP), a joint venture behind $400 million worth of solar powered  projects, started groundbreaking work on Friday with more than $10 million worth of investment in Kampong Speu province.

It will be the first step for producing about 15 megawatts to supply the industrial zone.

The GPP is a joint venture involving Cambodian, Thai and Laos investors, and has had a licence from the government to produce solar power since December 2015.

The company plans to invest $400 million in solar projects to produce 225 megawatts or more for businesses, factories and other industrial zones in Kampong Speu, Kampong Chhnang and Takeo provinces.

Director-general of the Energy Ministry’s general department of energy Victor Jona, who presided over the groundbreaking ceremony, said on Friday that the company had just started its first investment, in Kampong Speu, since getting the licence.

“We support the project, especially as it complies with the government policy of using renewable energy such as solar power to supply in our country,” he said.

“Today [Friday] is the start of the company’s pilot project to construct a 15 megawatt solar power plant to supply clients at an industrial zone in Kampong Speu province.”

GPP is the second project of a solar power farm in Cambodia after the first one was launched recently in Svay Rieng province with 10 megawatts invested by Sunseap Asset (Cambodia), the local subsidiary of Singapore-based Sunseap International.

Sunseap invested $12.5 million into the project and plans to sell the power to Electricite du Cambodge (EDC) to supply to the national grid.

“In 2016, the Ministry of Mines and Energy, together with Electricite du Cambodge, had bid for a 10 megawatt project, which is being launched in Svay Rieng,” he said.

According to the Economic Research Institute for Asean and East Asia, in 2013 only 34 percent of Cambodian households had access to electricity, which is one of the lowest electrification rates in Asean.

The current cost of electricity is high, ranging from $0.15 per kilowatt hour in Phnom Penh to $1 per kilowatt hour in rural areas. Due to the high cost of electricity in rural areas, there is an opportunity for solar home-based systems.

However, Mr Jona, said that GPP would have difficulties with their investment because they would have to find customers themselves to supply other businesses, factories and industrial zones while the state-owned EDC already covered 70 percent of the power supply nationwide.

“GPP cannot sell to EDC because it already has contracts to buy electricity from hydro power and coal-powered plants,” he said.

The government has set a target for power coverage across the country. By 2020 the aim is to have power to all 14,168 villages in Cambodia.

As of the end of June, the government provided power to 79 percent of the villages, according to Mr Jona.

Small project in the city. What is holding the people who seem to afford the smaller projects seems to be the lack of selling back to the grid. Also the country's commitment and policy to hydro.

 

Solar power takes the spotlight

 

In a bid to further electrify the country and reach households in remote areas, Cambodia is encouraging local and international companies to undertake projects in the country’s fledgling sustainable energy sector, but a lack of options to sell excess energy to the national grid is keeping many projects from taking off.

A host of companies is showing interest in starting green energy projects in Cambodia and have been granted permission to do feasibility studies for solar power plants, said Ith Praing, secretary of state of the Ministry of Mines and Energy (MME).

However, Mr Praing continued, those preliminary studies have so far failed to materialise in any sizeable investment.

Cambodia has immense potential when it comes to solar energy given the long hours of sunlight the country enjoys every day, Mr Praing explained during a regional conference on Energy Security in CLMV Countries that took place yesterday in Phnom Penh.

“Many companies have asked to conduct feasibility studies on solar energy development, and we have allowed some of those studies while we study how to connect projects to the national grid,” Mr Praing said.

“However, none of those studies have turned up positive results,” Mr Praing said, explaining that the country still lacks a feed-in tariff or not metering system that credit companies who add electricity to the grid from their solar panels.

A 10-megawatt solar power plant came online last August in Svay Rieng province’s Bavet city, the country’s first significantly-sized solar power project in the country.

A feasibility study for a new 100-megawatt project is now being carried out and will be finished by the end of 2017, Mr Praing said, adding that the project is run by the Asian Development Bank, Electricité Du Cambodge (EDC), and the Ministry of Mines and Energy, although he failed to disclose where the project will be located.

If preliminary studies yield satisfactory results, private companies will be invited to bid for the project, he added.

Han Phoumin, energy economist at the Economic Research Institute for Asean and East Asia (ERIA), urged the government to put in place a system that allows companies to sell the energy they produce to EDC, the only electric utility in Cambodia.

“It is important that the ministry allows companies to develop mini-grids like in Bavet for their own consumption,” Mr Phoumin said.

“Mini-grids can be connected to the national grid because solar energy is intermittent. When they generate power at a surplus, they need to be able to sell that electricity back to the grid.”

According to the Rural Electrification Development Program, the government’s goal is to have all villages in Cambodia electrified by the year 2020, and at least 70 percent of households nationwide connected to the grid by the year 2030.

According to MME, already 80 and 70 percent of each goal has been achieved respectively.

Total energy consumption in the kingdom now amounts to 2,000 megawatts per year, 60 percent of which is generated from the country’s six hydropower dams, while 20 percent is imported – 15 percent from Vietnam, 4.5 percent from Thailand, and 0.5 percent from Laos. The rest of the energy comes from biomass and coal-fired plants.

Does the rainy season put the damper on viable solar power? 5 or 6 months with much rain and clouds must have an impact. No sun = no power, right?

True, no sun, no power. But, when you design a solar array for a home, business, etc., you calculate for days of autonomy, or days without sun. Typically, most systems are designed for 3 days of autonomy. When I designed our first solar array, I designed it for up to 7 days of autonomy. Cost is considerably more, though, in doing so. 

 

Now, although batteries are still around $1.35 per AH, solar panels have dropped to as low as $.64¢ USD / watt. So, slowly but surely, systems are getting cheaper.

@dicey eye, nowadays, for less than several hundred dollars, you can set up a grid-tied system that will pump power back into the grid for you. It will not provide power for you when the grid is down. BUT, it will considerably reduce your power costs, which will save you money over time. If you design the system to generate just under your typical power consumption, you would end up with a very low power bill each month, indefinitely.

While batteries are still a bit costly, panels use to cost quite a bit more than they do today. I recall my first solar panel costing around $10 USD per watt. I could only afford one, back then.

Leading solar firm to increase investment in Cambodia

 

September 14, 2018 Khmer Times

 

With one of the world’s highest average peak sun hours, Cambodia is an attractive market for any company operating in the thriving global solar industry. Indeed, one of the world’s largest manufacturers of photovoltaic (PV) panels, is now seeking to increase its presence in the country.

Government happy for Chinese dominance of Cambodia energy sector to continue

 January 15, 2017

 

When Vietnamese forces liberated Cambodia from the genocidal reign of Pol Pot in 1979 they found the country devoid of necessary infrastructure. Roads, bridges, water and sanitation services, and power generation and distribution networks had all but been totally destroyed. While some progress was made on restoring these services in the wake of the Khmer Rouge, it wasn’t until 1999 that real progress began, at least according to Cambodia Minister of Mines and Energy, Suy Sem.

In an interview with Xinhuanet, Mr Suy said 1999 and the declaration of the ‘win-win strategy’ by Prime Minister Hun Sen and the end to internal conflict marked a new era in the Cambodia energy sector. “Chinese investment in developing the sources of electrical energy is like the building of a new history for Cambodia”, Mr Suy said.

China is the largest investor in the Cambodia energy sector, ‘assisting’ Cambodia in the construction of six hydro-power dams since 2000 at a cost of some US$2.4 billion. It is also the dominant partner in the 70 per cent complete 400 megawatt (MW) Lower Sesan 2 hydro-power plant being constructed at a cost of $816 million due to come online in 2019.

Noting that over the past 14 years China’s contribution the Cambodia energy sector has increased 11 times – from 180 gigawatts (GW) in 2002 to 1,986GW in 2015 – Mr Suy said this has enabled electrification to 72 per cent of the kingdom’s villages. By 2020, he said, it is planned that every Cambodia village will have access to electricity.

China completely finances nearly all of Cambodia’s hydropower projects

 

According to Suy Sem, minister of Cambodia’s Ministry of Mines and Energy (MME), with the exception of the US$781 million 400-MW Lower Sesan 2 project on the Se San River in northeastern Cambodia, Chinese companies have provided 100% of the financing for all hydropower projects in Cambodia.

According to Xinhua, Sem made the comments Oct. 10 at the World Energy Congress in Istanbul, Turkey.

The estimated cost for the plants is about $2.4 billion dollars and is also part of Sino-Cambodian cooperation in the energy sector under the One Belt, One Road (OBOR) initiative, he said.

Sem said six hydropower projects have been built in Cambodia and construction of the seventh, the Lower Sesan 2, is 70% complete.

The Lower Sesan 2, expected to be commissioned in 2017, is a joint venture between Chinese, Cambodian and Vietnamese companies. Chinese firm Lancang Hydropower International Energy holds 51% ownership, Cambodia’s Royal Group owns 39% and Vietnam’s EVN International owns 10%.

      This is between an off-grid project and a mains electrical project. So, I wasn't really sure where I should post it. The Mains, Solar, Wind & Hydroelectric Power forum won.
       
      So, it just so happens that I have 3 - 100 watts panels sitting around collecting dust, and not producing a single watt of power. I also have 135 watts panels doing the same. So, I need to come up with a little project for them. Anyway, the 100 watts panels project, for now.
       
      I am going to buy a (cheap Chinese made) 6oo watts grid-tied inverter. I will then connect the 3 - 100 watts panels in parallel, directly to the inverter. Then, I will plug the inverter directly into a mains power point (wall receptacle). That will sync with the mains and start pumping up to 300 watts directly into the electric veins of the farm, depending on the amount of sun they receive, of course. This will help alleviate some of the power needed from the mains to run the farm. 
       
      Anyway, these inverters run between about $82 USD to $120 USD, each. That would buy you a 500 watts, up to a 1000 watts grid-tied inverter. 
       

       

       

       

       
      The reason behind powering a 600 watts grid-tied inverter with only 300 watts of panels, is so as not to overdrive it and possibly cause it to fail, catch fire, etc. The last thing you want to do, is to overdrive a cheaply made inverter, or any inverter for that matter. Besides, you can always buy another inverter, and three more panels to connect to it, then plug it into the mains. The second inverter will sync with the first, as well as the mains voltage. 
       
      Also, when you experience a mains power failure, these inverters will automatically shut down in order to protect anyone who may be working on the cables. You certainly don't want to be responsible for someone getting electrocuted. I know I don't. Once power is restored, they will come on line again.
       
      Anyway, as soon as I get around to ordering one of these, and receive it, I will give you good folks an update on this little project. If this works out okay, I will definitely expand the system so as to reduce our power bill even more, each month. 
       
      SUMMARY: A grid tied system can help you kill your power bill, by back feeding power into the mains. It is as simple as installing an array of solar panels, connecting them to a grid-tied inverter, and connecting the grid-tied inverter to your mains power in your home.

      I am continuing with a project I have been researching and wanting to complete for some time.

      After calculating everything I would need to power, including lighting, I have determined a 300 watts solar array is what I would need to start with.

      To begin with, the array will be made up of 3 - 100 watts solar panels. I will add additional panels to expand the total array output.

      I was going to order a single 285 watts Yingli, but recently decided against it due to a couple of reasons.

      One reason was time constraints. I want to finish this system this up coming week. It would take me about two months to get the panel here.

      Another reason was no guarantee of the panel being received in good condition. After all that waiting, I could end up with an issue with the panel. Knowing my luck, I figured I would go with the safer option - let the company I buy from replace a non-working panel at his cost, not mine. Not to mention, the local supplier has all the panels I need in stock, and then some. If I want to expand the system, it will be as simple as dropping by his office, picking one up and taking it to the site and installing it in the current array.

      I will start with four (4) deep cycle batteries, 120 amperes each, on a 12vdc system. I am leaving room for expansion panels as well. I will probably add three to five more panels, over the next several months, as power requirements increase.

      The batteries are connected as below, to help guarantee equal charging among each battery in the bank:


      I am going with a MorningStar Solar Controller for the array. The model controller is a Morningstar ProStar-30 (meter version). They have a great reputation among solar power enthusiasts, and from reviews I have read online.


      Take a look at their 2012-2013 catalog: Morningstar-catalog-2013.pdf
      UPDATE: Here is their 2013-2014 catalog: 2013-2014-MS-Catalog-Oct-EN-small.pdf

      I haven't decided on a voltage inverter yet, primarily because I have one already that I can use, until I have decided what to do there. All lighting will be 12vdc. The bulbs will screw into standard lighting sockets.

      Total cost, a modest $835 USD. I will have a complete 300 watts solar array installed and running, for this cost.

      I won an auction today, one I didn't expect to win. Honestly, I had second thoughts about even attempting it. Money is a tight with what we are putting into the farm. But, I figured if I could keep it under $160 USD, I would give it shot. I just remained apprehensive about getting it, because most on auction sites are more costly than the figure I set as my maximum bid. But, sometimes, you get surprised - you win. I did today. 
       
      It's a 1,500 watts continuous, 3,000 watts intermittent, 12vdc to 220vac, 50hz, soft start pure sine wave voltage inverter. Chinese made, but most are nowadays. Will see how well this one holds up. Besides, I won't be maxing it out anyway - far from it. I figure 500 watts will be the maximum draw this ol' boy will see for some time to come. Anyway, I won the auction at $156 USD, including shipping, to Cambodia. 
       
      If you have the option, you will be much better off running a pure sine wave inverter, rather than a modified sine wave inverter. Electric motors, especially aren't crazy about Modified Sine Wave power. They run much more efficiently, and are better for running your appliances.
       

       

       

       
      For the record, the most recent prices I got, from a Chinese company nonetheless, are as follows: 
       
      1,500 watts - MSW - plus shipping : USD118.30 + USD  53.70 (DHL) = USD172.00 2,000 watts - MSW - plus shipping:  USD127.20 + USD  58.80 (DHL) = USD186.00 1,500 watts - PSW - plus shipping :  USD193.00 + USD110.00 (DHL) = USD303.00 2,000 watts - PSW - plus shipping:   USD221.00 + USD115.00 (DHL) = USD336.00

      During my first trip to Battambang, the first week of this month, we sat down with a representative from Khmer Solar. We spoke for a while, and let her know what we wanted installed, concerning our solar array at the farm house. At that time, she seemed fairly knowledgeable about solar power in general. I felt comfortable enough. So, we laid sthe deposit down on the table, and asked her for an official quote on company letterhead, as well as a receipt for the deposit.
       
      Stupid me - I would later learn.
       
      I should have asked her a few more questions prior to paying the deposit. For example, she should have been queried concerning the difference between PWM (Pulse Width Modulation) and MPPT (Maximum Power Point Tracking) controllers. We ended up going with a PWM controller, well - because it was the ONLY type they had available. Got to love limited choices when trying to set up a tailored solar solar array at your home.  Do a lot of research on any solar installation company in Cambodia, prior to doing business with them.
       
      By the way, if you are interested, the differences between PWM and MPPT is explained in the following PDF document:
       
      Trad-PWM-vs-TrakStar-MPPT-April-2013.pdf
       
      The first part of October is well into the rainy season, here in Cambodia. Little did I know, we had arrived in Battambang just before one of the worst monsoons in the past few decades. Knowing my luck, I should have guessed that one the minute the rains started to come down.
       
      So, we ended up heading home later that week (after 8 days in the hotel), due to the major flooding caused by the heavy rains that Cambodia was experiencing at the time. Nothing was completed during that trip, with the exception of purchasing the rain water harvesting project parts. That was a shame, really. Lots of water we could have stored, was simply lost. That's okay. Next rainy season we will be cookin' with gas!
       
      Fast forward to the third week of October. 
       
      On Monday, the 14th, we headed back up to Battambang. This time, we decided to do it with a one night layover in Phnom Penh. The next morning, Tuesday the 15th, we headed on to our destination city - in a no-so-comfortable, seven (7) grueling hours ride. Fortunately, the hotel in Battambang was comfortable, as usual. After getting refreshed, we dropped by Khmer Solar's office, and scheduled the installers to show up Wednesday morning, 9am sharp. Yes, Paul, hold your breath for that one.
       
      We woke before day light on Wednesday, had breakfast, and off to the farm we went. At 7am, the representative rang us, letting us know the installers would not arrive until 9am. I informed her that we were there waiting, and they needed to get on the ball and get their asses up there. 
       
      Time to throw a wrench in your plan for the day.
       
      Sure enough, about 9:30am, Khmer Solar rang up again, letting us know the installers would not arrive until about 11am. I was not a happy camper, as they didn't have an excuse for being more than two hours later than previously agreed upon. This company was not looking good, in my eyes. Hindsight, people. Hindsight.
       
      About 11:00am, they had not arrived. So, we decided to head out to Highway 57, a good 5 kilometers away, to meet them and show them how to get to the farm. (I didn't want any further delays.) We waited along the highway about fifteen minutes before they rang us, letting us know they were 10 kilometers away. They finally arrived to meet us at 11:35am. 
       
      We led the way back to the house, with them following along.
       
      Arriving at the property, we, that was me and most of the male family members, as well as Chan, filled our hands with "solar stuff" and headed toward the house with it all. (Bear in mind, there is a dyke, a not-so-small dyke (about 20 meters across), between the road and the farm property. We had to cross it, and part of the perimeter of a rice field, to get to the farm house. Talk about rural living. Green Acres ain't got anything on us!
       
      FINALLY! Everything was there and ready to be installed - except the damned installers. They were out by their car, hood (bonnet) popped up, and using a voltage inverter and power tools to cut up some angle iron, which appeared to be 1" x 1", or perhaps 1.5" by 1.5". (They apparently, had been constructing the bracket to which the panels would be mounted.) 
       
      A while later, they finally crossed the dyke, and with the balance of the parts in hand - the frame, a ladder, and one solar panel. By now, we were bumping on 2pm. Needless to say, I was definitely NOT happy with these people. I mean, Khmer Time is fine for most things. However, when it comes to work engagement, especially after you have agreed to a specific time, that is just rude and disrespectful as hell to your customer. Not to mention the money we were paying these guys to get this done - $110 USD, just in labor and deliver fees! They were not worth 10% of that! 
       
      It gets worse.
       
      Once inside, one installer, the one in charge, began taking out his little handy dandy combination wrench, and started tightening down the already tightened (snug, as they should be, by me!) battery terminal bolts on one of my batteries! The fecker thought he was Arnold Schwarzenegger. Bear in mind, these are battery terminals that were ALREADY torqued to appropriate specifications. It doesn't take a rocket scientist to determine what a half turn past snug means.
       
      I immediately stopped him from continuing on, and hollered for Chan to come into the house to translate for me. She was some distance away from the house. So, I had to get my big boy voice out to get her to go there - fast - before I ended up killin' this guy and burying him in the rice field! Basically, and I am sure, by using much nicer words than I had, she convinced him to leave my batteries alone, get out of the house, and climb his happy arse on the roof to start the panel install.
       
      I later found out that the installer had told Chan that the batteries would not charge properly, unless the terminals were "tight". Well, apparently, his idea of "tight" was measured in inch-tons of pressure, not foot-pounds. The idiot.
       
      After I saved the batteries from being tightened into oblivion and ruined, I grabbed the charge controller, a MorningStar ProStar 30m (with meter) and began installing it. Khmer Solar was very limited in their stocks, having only one other controller on hand. It was also a PWM. So, I chose, what I felt to be, the best option - the ProStar 30.
       
      The meter on the ProStar 30 rotates reading Battery Bank Voltage (the voltage at the batteries), PV Amperes (charging amperes from the panels), and Load Amperes (what your circuits are drawing from the batteries), continuously.
       
      Below, you can see the controller is showing the panels are charging the batteries at 13.8vdc, and in the second image, charging at a rate of 10.1 amperes.
       

       

       

       
      If you are interested in a rural project similar to ours, and want a decent controller that is fairly reasonably priced and packed with features, I can recommend the MorningStar ProStar 30M Charge Controller. I would recommend buying one from the states, though, as you can import one cheaper than you can buy one locally. Here is information you may find beneficial about this particular unit:

      Now, to keep this story from getting much longer - yeah, I know, too late for that, Paul.
       
      Well, the bottom line here is, everything these guys worked on ended up shotty. I wish I could have taken a photo of the bracket they mounted the panels to. (EDIT: I have since purchased a camera and taken images. A photo of the controller and one of the controller and current combiner box is above. A photo of the (installed) bracket is below this paragraph.) Oh, yeah, the panels. They cut the FACTORY INSTALLED MC4 plugs off brand new PV panels so the installer could junction the wires on the panels. This was done rather than buying the proper MC extension cables to add length for the wires to the combiner box. There goes the 20 year warranty on three PV panels.
       

       
      Oh, when they mounted the bracket and panels, they didn't bother to see what angle the roof was at, which would determine the proper elevation (just under 13.00 degrees) for the panels. (I have an azimuth / elevation gauge I will take back with me, to make sure the elevation is correct.) 
       
      I am glad I changed the setting on the controller to lead acid (flooded) batteries. (There are three settings, depending upon which type of battery you will be using for the array.) The installer didn't even bother to check it to make sure it was on the appropriate setting, when he connected it! 
       
      To top it all off, they didn't finish the install until that evening - long AFTER sun down. Soooo, we couldn't even check to see how well the panels were performing until the next morning. 
       
      So, folks, if you are looking for a solar array to be built on your property, definitely, do NOT EVER use Khmer Solar. I cannot believe a professional business could be so shotty. But, they are. 
       
      As far as I am concerned, the next install / upgrade we do concerning the solar array, will be done entirely by me and Chan's family. An extra $110 USD would buy us a lot of beer for the after install party.
