Electricity


Malaysia is promoting coal as a fuel of choice for power generation, to free up more natural gas for export.

Malaysia has approximately 16 gigawatts (GW) of electric generation capacity, of which 87% is thermal and 13% is hydroelectric. In 2003, Malaysia generated around 79 billion kilowatt hours of electricity. The Malaysian government expects that investment of $9.7 billion will be required in the electric utility sector through 2010. Much of that amount will be for coal-fired plants, as the Malaysian government has adopted a policy of attempting to reduce the country's heavy reliance on natural gas for electric power generation.


The largest thermal project under development in Malaysia is the 2,100-MW coal-fired Tanjung Bin project in Johor province. Sumitomo was awarded a $1.5 billion contract in early 2003 by SKS Power, a Malaysian IPP, for the construction of three 700-MW generating units at the site, with the first unit scheduled to begin commercial operation in August 2006.

In 1994, the Malaysian government granted approval for the massive 2.4-GW Bakun hydroelectric project in Sarawak. Scheduled for completion in 2002, the Bakun Dam had been slated to send 70% of its generated power from Sarawak to Kuala Lumpur through the construction of 415 miles of overhead lines in eastern Malaysia, 400 miles of submarine cables, and 285 miles of distribution infrastructure in Peninsular Malaysia. In addition, expansion plans included a high voltage line south to Johor Baharu and north to Perlis, near the western Thai border. A local company, Ekran, was awarded a turnkey contract to manage the project in January 1995. In 1996, the construction contract went to Sweden's Asea Brown Boveri (ABB). However, in early September 1997, the Malaysian government announced that it was delaying the project indefinitely, citing an unexpected rise in the dam's cost due to the country's economic difficulties at the time.

In mid-1999, work resumed on the river diversion tunnels, a major component of the project, which has since been completed. The Malaysian government has taken control of the project and negotiated financial settlements with the firms involved. The subsea transmission line concept has been abandoned, and the Malaysian government is exploring the possibility of sales of electricity to Brunei and Indonesia. While it had appeared likely that the project would be scaled back from its 2,400-MW capacity, the Malaysian government announced in February 2001 that it had decided to complete the project on its original scale. Bids were received in July 2002 for the main construction work for the dam, and a construction contract was awarded to a consortium of six Malaysian and Chinese companies in March 2003. Current plans call for the 300-MW generating units to be brought online in stages, with the first capacity to come online in 2007. While electricity demand in Sarawak is modest (currently under 1 GW), the potential to use the electricity to develop a metal smelting industry in Sarawak is largely behind the renewed interest in the project.

Malaysia is considering reforms to its power sector to make it more competitive and lower costs. Currently, three state-owned utilities dominate power generation and distribution in Malaysia. The market was opened to independent power producers (IPPs) in 1994, and 15 IPPs were licensed, though not all of the projects have been built.

Tenaga Nasional Bhd, the main state-owned utility, began in 1999 to divest some of its power generation units. Eventually, Malaysia expects to achieve a fully competitive power market, with generation, transmission, and distribution decoupled, but reform is still at an early stage and the exact process of the transition to a competitive market has not been decided. The issue is still under study, and many observers have voiced caution in light of the experiences of other deregulated utility systems.

Focus: Solar power shining in homes of Malaysian natives

( 2003-11-19 10:11) (China Daily)

Rompin, Malaysia: For generations, residents of the tropical jungles of the eastern coastal area have tried to make their homes as cool as possible by shunning the scorching sun.

Now, they have shifted their efforts towards harnessing a tiny fraction of the abundant solar energy to light up their rooms and kids' schools. Those efforts are aided by the country's electricity research fund.

A big smile on the face of 62-year-old Abio, leader of the Kampung Denai Village, says plenty about the benefits of the country's first centralized solar power station.

"It's great. We can watch TV and DVD now after our rooms have been connected by the electricity cables with the solar energy station," said Abio.

The village is inside a forest paradise, about 40-minutes away from the town of Rompin in the state of Pahang.

Together with more than 100 villagers, Abio's family lived inside the forest in Pahang state, an immense stretch of rainforest older than those of the Congo or the Amazon.

The remote location of some villages makes it difficult to access the electric grid and, through it, the conveniences of modern life.

Abio, a father of 10, said his family used candles at night. Unfortunately, they only lasted about three hours and, by 10:30 pm, the family was in the dark.

"Now, kids can read longer because the solar energy power station can provide an around-the-clock supply," said Abio, who lives about 1 kilometre away from the station.

The station, which is linked by a bumpy village road to the outside world, consists of solar photovoltaic cell, batteries, a generator, an inverter and other equipment.

Also inside the walled 200-square-metre station, are the attractive photovoltaic panels.

These panels are primarily made out of silicon, phosphorus and boron. When they are struck by the sun's rays, the combination of these materials produces electricity.

This electricity is sent to a battery where it is stored for future use. The stored energy can operate computers, lights, televisions, heaters, air conditioners, cars and even video games.

Including Abio's family, 27 households in the village have benefited from Malaysia's first centralized solar power station built by the Tenaga Nasional Berhad, Malaysia's premier electricity utility.

The research and development oriented organization is committed to enhancing power quality in the region.

The project head, Hamdan Hassan, said their responsibility will go beyond that, although global warming and environment protection may still be a novel concept for Abio and his villagers.

"The incentives to exploit solar energy are at least two-fold," said the Hassan.

First, we cannot depend on non-renewable fuels forever.

"The supply is bound to finish, if not during our lifetime, perhaps in the next or two generations."

Second, despite the many preventive and corrective measures undertaken by those involved in the production of energy from fossil fuels, environmental degradation due to the emission of pollutants still persists.


He said the country has designed a step by step approach to light up 15 villages with centralized solar power stations.

"Now, the village is lit up without any charge. We will make them learn to make money and make the project pay off," said Hamdan.

The villagers used to earn their living by fishing in the river inside the jungle. But their basic living necessities have changed due to a growing population.

The local government allowed every family 6-8 acres of land to plant oil palm, a major cash crop and export of Malaysia.

"They can get a harvest in two or three years and then we can be paid off," said Hamdan, adding that the equipment for the solar stations was imported from Australia-based Advanced Energy System.

Since Malaysia does not experience seasonal climate, the electricity generated by the sun remains relatively constant throughout the year. Electricity production can start at 9 am, peak at noon and stop at around 6:30 pm.

As to the station in the village, the solar energy stored in the batteries lasts for at least five days.

"So far, we have not experienced blackouts here because the sun is always in the sky during the day time," said Hamdan.

Malaysia's effort to promote sustainable ways of energy production goes beyond the pilot project. As the third largest per capita greenhouse gas emitter among the 10 ASEAN nations, Malaysia is committed to using sustainable energy - including solar power - and reducing its greenhouse gas emissions from all sectors.

Installations of decentralized solar PV cells are done mainly in rural areas, where setting up electric cables is difficult.

The country has planned to produce 5 per cent of its total energy needs with renewable sources by 2005. With gas, coal and oil being lion's share of the world's energy sources, sustainable alternatives including hydro, solar, wind and biomass power currently produce 14 per cent the world's total energy use.

Solar energy comes with a price

Maria J. Dass

SUBANG JAYA: Solar energy, whether in the form of light or heat, may be free but getting electricity out of it will come at a price.

In several remote parts of the world where infrastructure is scarce, including villages in the country, electricity is obtained from solar energy, which has long been promoted as a clean, efficient and renewable source of power for all Malaysians.

However, middle and lower income households in Malaysia may only be able to afford such photovoltaic (PV) technology in their homes in about 10 years.

This is because the government plans to promote this technology among the high income group in urban areas first.

Ahmad Hadri Haris, who heads the Malaysian Building Integrated Photovoltaic (MBIPV) national project, said efforts to drive the growth of BIPV will be focused on urban areas - which are grid connected - and will be private sector and investment driven.

"Right now the cost of BIPV is high. That's why we are targetting the high income group, because that's where the market and customers with buying power are," he said at the BIPV seminar, "What's in it for me?" here on March 17, 2006.

"This way the government's investment is reduced and the people who can afford to install these panels for now will absorb the initial cost," said Ahmad Hadri.

"So when the demand increases and the market is developed, the cost will come down, making it affordable to other users, including those in rural areas," he added.

The seminar was organised by the Malaysia Energy Centre in collaboration with the Energy, Water and Communications Ministry, the United Nations Development Programme and the Global Environment Facility.

Currently, consumers may have to fork out RM150,000 to RM300,000 to install a BIPV system in their homes.

"The idea is to build up a sort of branding, niche market and appeal for the product among the high income group and those in the upper middle class.

"This, we hope will trickle down to the other groups in the lower rungs of the social strata when the cost comes down eventually," said Ahmad Hadri.

"We hope that owning solar panels will become something of a statement of being cool, fashionable, and a sign of environmental awareness and high technology," he said.

"New high-end housing projects will also soon offer the option of installing these solar panels.

"This can be accommodated, with perhaps an option for housebuyers to incorporate the costs into their loans," he added.

To promote the use of solar energy, the Malaysia Energy Centre plans to offer the public incentives for installing a BIPV system in their homes.

Currently, only companies are entitled to such incentives.

Industry observers have pointed out that the success in encouraging the public to use BIPV in other countries was fueled by tax incentives given by the government to those who adopted the technology.

The centre will also be launching a National Suria 1000 programme,

The programme will aim to encourage BIPV installation in residential and commercial buildings before the end of this year.

PV application in Malaysia started in the 1980s to generate power for communication towers, oil and gas facilities, calculators and some rural systems.

Stand-alone PV systems are used by the Malaysian Nature Society in Endau Rompin, in Gunung Machinchang in Langkawi, parking ticket machines as well as emergency phones in certain stretches of some highways in the country.

The Ministry of Rural and Regional Development also has an ongoing rural electrification programme which involves the use of solar energy.
