Why solar? why thin film?

Monster of the Mekong
Sat, 21 June 2014, Tom Fawthrop
It will be a giant, stretching across the mighty Mekong River.
Standing 32.6 metres tall and 820m wide, the $3.8 billion Xayaburi dam
in Laos could supply electricity to more than three quarters of a
million homes in Thailand. And when it’s completed in 2019, it will be
the most controversial power project in the region.
Since the plan was released in 2010 to construct the hydroelectric
plant, geologists and environmentalists have voiced concerns about
safety and the effects the mega-dam will have on neighbours Cambodia,
Vietnam and Thailand. They have highlighted the risks of seismic
activity in the area and the threat to the fishing industry on the
3,100-mile long (4,900 kilometres) Mekong River, which flows from the
Tibetan steppes into southern China on its way to Myanmar, Laos,
Thailand, Cambodia and Vietnam.
“Previous earthquakes near the Xayaburi dam site should have served as a warning for Laos and the Thai dam company,” said Ame Trandem, the Southeast Asia programme director for the conservation group International Rivers. “It is completely irresponsible to push forward with a project located in a seismically unpredictable zone.”
During the past seven years, the area around the Xayaburi dam project has been shaken by earthquakes. A 6.9 magnitude quake hit Shan state in Myanmar. A 4.6 tremor only 48 kilometres away from the proposed project was recorded in 2007, while a 6.3 convulsion was reported in the Xayaburi area in the same year.
Naturally, this has alarmed Dr Punya Charusiri, who heads earthquake studies at Chulalongkorn University’s Department of Geology. The Thai scientist has identified an active fault close to Xayaburi town about 30km from the site. “I am worried that many people from the town would be affected. But I am not able to predict how much damage would be done to the dam itself, which is built on an ‘inactive fault’,” he said.
The risk factor is certainly there. During the 7.9 magnitude earthquake in Sichaun, China in 2008, the walls of the Zipingu dam were badly damaged and came close to unleashing a second disaster of epic proportions.
“In a worse case scenario, if a [major] earthquake happened right under the [Xayaburi] dam, then nobody knows,” said Dr Sampan Singharajwaranpan, a seismologist and the dean of sciences at Chiang Mai University.
Safety, of course, is not the only concern. Fears are growing about the impact on the environment and ecology of the region when the Xayaburi dam, one of nine hydropower plants planned by the Laos government, is up and running. More than 30 million people in Cambodia and Vietnam rely on the Mekong River for their livelihoods. Rice and fish exports could be threatened in the inland waterways, which generate up to $3.9bn in revenue a year, equivalent to a quarter of the world’s annual catch.
Up to 40 species, such as the giant catfish, are under further threats from the dam, according to a report commissioned by the World Wildlife Fund (WWF). “Mortality is likely if fish pass through dam turbines [and] . . . the cumulative impacts of the dam are a serious threat,” said Zeb Hogan, an associate research professor at the University of Nevada in the US, and author of the report. “A fish the size of a Mekong giant catfish will simply not be able to swim across a large barrier like a dam to reach the spawning grounds.”
The Cambodian government is also anxious to avoid fish stocks being damaged. This in turn could lead to dietary problems if the industry is badly hit. “[Fish provide] 76 per cent of animal intake, 37 per cent of protein intake, 37 per cent of iron intake and 28 per cent of fats intake of the Cambodian population,” a study by the Cambodian Fisheries Administration (CFA), a government body, revealed.
Nao Thuok, the director of the CFA, underlined Cambodia’s concerns when he said the “protection of fisheries in the Mekong should be regarded as an issue of national security”. The stakes are so high, a joint declaration, released in March, from 39 non-governmental organisations (NGOs) in Cambodia, Vietnam, Thailand and Australia set a one year deadline for the Laos and Thailand governments to scrap the project. “There is still essentially one year left to stop the dam as construction on the Xayaburi [power project’s] final dam across the Mekong River will begin in 2015,” said Trandem of International Rivers.
As the clock ticks down, the pressure is building on CH. Karnchang, the Thai group that will construct the dam, and partner Poyry Energy, part of the Finnish-based international engineering company and consultants Poyry. The Thai government has also been dragged into the dispute after agreeing to buy 95 per cent of the electricity generated at the hydropower plant.
One major concern aired by independent geologists has been the lack of transparency from CH. Karnchang and Poyry Energy about crucial seismic studies. Te Navuth, the secretary general of Cambodia’s National Mekong Committee, had called for “an independent research team [to] assess the risk of earthquakes and dam safety” back in 2011.
Two years after construction began, the Mekong River Commission (MRC) received “[a] seismic hazard assessment” which was drafted by Poyry Energy and AF Consult, the Swiss company based in Zurich. The MRC referred the “assessment” to an independent expert, but so far the Cambodian government has yet to see the report.
“The seismic hazard at the Xayaburi dam site has been studied thoroughly and the dam, the powerhouse, and the spillway will be designed against earthquakes, according to the latest seismic design guidelines prepared by the International Commission on Large Dams [ICOLD],” said Dr Martin Wieland, the managing Director of Poyry Energy.
Critics of the project have expressed disquiet about ICOLD and claimed that it is not an independent research body, but a forum for the dam engineering lobby largely funded by hydropower companies. Dr Wieland, of Poyry, is also chairman of the committee on Seismic Aspects of Dam Design for ICOLD in charge of seismic guidelines.
“The CH. Karnchang people assumed that the faults closest to the dam-site are inactive, and so they believe it is quite safe,” said Dr Punya, who has also worked for the CH. Karnchang group. “But there is an active fault and it is located within a 30km radius. Construction should never have been started before the research into the danger has been completed.”
As the row continues, regional government heavyweights have warned of the dangers ahead if the Xayaburi project is completed. “We have to protect our interests,” said Lim Kean Hor, the Minister of Water Resources and Meteorology in the Cambodian government. “We will not allow [construction] if there will be a serious impact.”
Just like the huge scale of the Xayaburi hydropower plant, the arguments against the project have grown from a trickle to a tidal wave. What happens next could change the course of the Mekong River for generations to come.

Residents left in dark again
Fri, 13 June 2014, Sen David and Stuart White
Residents in the vicinity of Kab Ko market in Phnom Penh’s
Chamkarmon district found themselves fumbling in the dark yet again
yesterday on the second consecutive day of hours-long power outages.
According to locals, electricity to the street failed around noon on Wednesday and was restored at about 10pm that night, only to fail again around noon yesterday, driving down trade and serving as a general headache for residents and business owners alike.
“The electricity is very important to make a living,” jewellery vendor Chan Vanta said. “I need light for my business as a gold seller to attract the customers, but for two days there have been few customers coming to look … and buy some jewellery.”
Sitting in a still, dark, empty dining room, the owner of the usually popular Phsar Kabko restaurant agreed.
“After the electricity was cut … there were fewer customers,” he said. “Right now the days are very hot, and customers need a fan.”
The restaurateur, who asked to be identified only as Mean, said he had been forced to resort to iceboxes to keep his produce and drinks cold after the power outage killed his refrigerators, but the run on ice that ensued after the outage made it hard to find.
The blackout was also causing problems on the home front, resident Sam That said.
“We need a fan, air conditioning and light to live, because it is too hot, and we need electricity for my daughter to study, use the internet and watch TV,” she said. “We heard about an EdC [Electricité du Cambodge] release, but we can’t do anything.”
An official at EdC who declined to be named would not comment in detail, but offered a statement pertaining to construction in Por Sen Chey and Meanchey districts, among others. Due to interconnected power grids, work being done there could have an effect elsewhere in the city, the official said.
“The EdC would like to inform the public that EdC will … remove some lines for road expansion construction, so [power in] some areas in Phnom Penh will be off until 14 June,” the statement reads. “We hope that the public will be aware and forgive us.”

Phnom Penh City Hall Hoping to Turn Garbage Into Electricity
By Ben Sokhean and Simon Henderson | June 9, 2014
The Phnom Penh Municipal Government on Thursday signed a memorandum of understanding (MOU) with Inter Far East Engineering Public Company Limited of Thailand to study the feasibility of turning the city’s waste into energy, according to a notice posted on the municipality’s website.
Mean Chanyada, the city’s deputy director of administration, said in the statement that the amount of garbage collected each day across Phnom Penh was expected to jump from 1,300 tons now to 2,000 tons by 2018.
“The quantity of garbage that has increased in Phnom Penh at the present has made problems and will affect the city environment if we don’t pay attention,” he said.
City Hall spokesman Long Dimanche said the MOU was a preliminary agreement for study and research and that the city hoped to find another five companies—or more—whose proposals would all be compared.
At Thursday’s MOU signing, Far East Engineering director Wichai Thavormwa Thanayon said the company’s plan would be groundbreaking.
“This MOU is a pioneer for recycling the garbage to electricity so that 200 tons of waste could be used to create five megawatts of electricity each day,” he said, according to the statement.
Inter Far East Engineering Public Company Limited has only recently moved into the alternative energy business. In April, it acquired True Energy Power Lopburi Company Limited, which operates a biomass power plant in Thailand’s Lopburi province with a capacity of 6.8 MW.
Thailand, however, offers considerable tax breaks to companies investing in renewable energy projects, something Phnom Penh City Hall has so far failed to do, said Yang Saing Koma, president of local agricultural NGO Cedac.
“Phnom Penh’s garbage problem is a serious one, so it is a positive to find ways to solve it. But so far, [City Hall] has struggled to encourage enterprises into recycling projects such as composting and biomass,” he said.
“If they wish to replicate what is happening in Thailand, they need to offer similar concessions such as tax incentives.”

Japan firm buys share of new power plant
Wed, 4 June 2014, Hor Kimsay
In what looks to be a concerted push into the Southeast Asian
energy sector, Japanese import and export conglomerate Marubeni
Corporation has acquired a large stake of Cambodia’s power generation
infrastructure.
In a Tokyo Stock Exchange filing dated June 2, Marubeni announced it had purchased a 20 per cent share of Malaysian firm, Leader Infrastructure Limited.
Leader Infrastructure operates Cambodia’s only 100-megawatt, coal-fired power plant in Preah Sihanouk province as well as a transmission network under subsidiaries Cambodia Energy Limited (CEL) and Cambodia Transmission Limited (CTL).
The power plant, which cost more than $195 million to build, began operations in February.
“Marubeni will contribute positively towards the operation of CEL/CTL and indirectly contribute towards the reliable power supply in Cambodia,” the Marubeni statement states.
“Marubeni envisages expanding its power business in Cambodia utilising its extensive knowledge and experience from its worldwide participation in the power industry.”
It’s the first time a Japanese company has entered Cambodia’s energy market, according to the statement.
It comes less than a week after Marubeni also announced it had entered a $977 million joint venture agreement with Tokyo Electric Power Co to expand an existing coal-fired power plant located in Pagbilao, the Philippines.
Hiroshi Suzuki, chief economist at Business Research Institute for Cambodia (BRIC), said he hoped Marubeni’s investment will bring know-how to Cambodia’s power sector.
“I hope the Marubeni’s participation encourages future large scale investments into Cambodia’s power sector,” he told the Post yesterday.
“[But] the size of Cambodia’s power sector market is not big enough to attract many [more] investment projects,” Suzuki added.
Suzuki also said Marubeni’s investment alone would not solve Cambodia’s power-related issues, such as the unstable supply and the high cost of electricity.
Leader Infrastructure received a 33-year build-operate-transfer land concession from the Cambodian government in 2010 for the Preah Sihanouk power plant project – three years for construction and 30 years for operation before handing the plant back over to the state.

Rolling blackouts ‘not in the works’: official
Tue, 25 March 2014, Khouth Sophak Chakrya and Sean Teehan

Phnom Penh
residents should experience blackouts less frequently this dry season,
as state-run Electricite du Cambodge (EdC) now has enough power to avoid
a repeat of last year’s rolling blackouts, a senior company official
said yesterday.
The amount of electricity Cambodia will receive from several hydropower plants, along with power purchased from Thailand and Vietnam and repairs made to electrical infrastructure in the capital, should ensure enough electricity to make intentional power outages unnecessary, said the official, who spoke on the condition of anonymity.
Reported blackouts so far this year can be chalked up to technical problems caused by the way Phnom Penh’s electric grid is set up, he added.
The grid “looks like blood vessels in our body”, he said. “If any one of our vessels is cut off, another part is affected; if a wire is disconnected from one household, it will affect others.”
My Sovann, media project manager for Urban Voice Cambodia, which tracks and maps blackouts on its website based on reports from individuals who notify the group, said it received reports of about 700 separate blackouts last year.
Although the EdC employee said scheduled blackouts will not happen this year, Sovann pointed to comments made last year by Ty Thany, executive director of the Electricity Authority of Cambodia, that the public should not be notified of EdC’s intentional blackouts.
“Cambodian citizens should have certain rights to information about blackouts, when and why,” Sovann said, adding that EdC operates with limited transparency and accountability.
“EdC is very powerful in making decisions and charging electric fees,” Sovann said.
“The government should check the agreement and license of EdC, and see how they have been … trying to improve the electric situation in Cambodia.”
Furthermore, planned blackouts in the past have occurred frequently in Phnom Penh’s poorer areas, but rarely happen in more wealthy parts, such as Phnom Penh’s Boeung Keng Kang I commune, said Ou Virak, chairman of the Cambodian Center for Human Rights.
Virak said he was unaware of any EdC efforts to eliminate intentional blackouts, he said, but if made public the time and place they occurred, people would see the disparity.
“If it was actually informed publicly, you would know how blackouts were being allocated,” Virak

“EdC is very powerful in making decisions and charging electric fees,” Sovann said.
“The government should check the agreement and license of EdC, and see how they have been … trying to improve the electric situation in Cambodia.”
Furthermore, planned blackouts in the past have occurred frequently in Phnom Penh’s poorer areas, but rarely happen in more wealthy parts, such as Phnom Penh’s Boeung Keng Kang I commune, said Ou Virak, chairman of the Cambodian Center for Human Rights.
Virak said he was unaware of any EdC efforts to eliminate intentional blackouts, he said, but if made public the time and place they occurred, people would see the disparity.
“If it was actually informed publicly, you would know how blackouts were being allocated,” Virak

Thin Film Vs Crystalline Solar Panel
Crystalline silicon photovoltaics is the most widely used photovoltaic technology. Crystalline silicon photovoltaics are modules built using crystalline silicon solar cells (c-Si), developed from the microelectronics technology industry. Crystalline silicon solar cells have high efficiency, making crystalline silicon photovoltaics an interesting technology where space is at a premium.
Silicon based thin-film photovoltaic technology makes use of the photo-electric effect of amorphous silicon (a-Si) and micro-crystalline silicon (µc-Si) semiconductor material to generate electricity in an environmentally sustainable manner. It compares favorably over conventional crystalline silicon PV technologies by generating more electricity (kWh) with the same installed power capacity in watts. However, both have different advantages and disadvantages by the following comparison of power and feature:
