41-548: Rajjaprabha Dam, meaning 'light of the kingdom', got its name in May 1987 from the king at the opening ceremony on the king's 60th birthday. Before that day it was called the "Cheow Lan Project". It was designed as a multi-purpose project for power generation, flood control, irrigation, and fishery. In 1982, the Electricity Generating Authority of Thailand (EGAT) started construction of the dam by diverting

82-1008: A former energy minister and other government members are on the board. It has been criticised as inefficient and an impediment to the development of renewable energy sources. As stated in EGAT's Annual Report 2017 : EGAT reported revenues of 494,119 million baht in fiscal year 2017 (FY2017: 1 January–31 December 2017). Net income was 59,042 million baht and total assets grew to 986,306 million baht. EGAT's power generation plants consist of three thermal power plants, six combined cycle power plants, 24 hydropower plants, eight renewable energy plants, and four diesel power plants. As of 31 May 2018 EGAT produced 37 percent of Thailand's electricity; independent power producers, 35 percent; small power producers, 19 percent; and electricity imports, 9 percent. Gas-fired generation powers 67 percent of EGAT's electricity generation while coal-fired power plants account for 20 percent. Most of EGAT's electricity

123-668: A back seat to network expansion. Opportunities for big savings exist: on 29 March 2014, Thailand observed "Earth Hour." For one hour, superfluous lighting was turned off, resulting in a savings of 1,778 megawatts, the energy equivalent of a new power plant, and more than six million baht in power bills. EGAT's plans for future developments have been dogged by protests by local residents: In mid-2015, government plans to build an 800 megawatt coal-fired electricity generating station (EGAT Coal-Fired TH #3) in Krabi Province have generated protests and hunger strikes by those opposed to

164-443: A few hundred megawatts to nearly 3,000 MW at the end of 2017. As IPP-supplied power purchases increase, EGAT's profits decline. As of May 2016, EGAT employed 22,955 persons. To shore up declining profits, EGAT intends to reduce its staff to 15,000 by 2021, the first staff cuts in its 49-year history. In the first half of 2016, Thailand imported 11.13 million tonnes of coal, up 3.5 percent from 10.76 million metric tonnes (mt) in

205-577: A public hearing on EGAT's plans to build a coal-fired plant was ringed with razor wire to prevent opponents of the plan from gaining access to the hearing. The hearing, the third and final hearing on the Environment and Health Impact Assessment (EHIA) for the 2,400 megawatt plant, was policed by 400 soldiers, police, and volunteers. Some attendees admitted being transported to the hearing by local village leaders, who also provided them with gifts and food coupons. Songkhla Governor Thamrong Charoenkul chaired

246-533: Is a huge social cost to coal and a huge social cost to fossil fuels ...if you want to be able to breathe clean air." EGAT "...has—in TV commercials—ridiculed renewable energy as expensive and insufficient to deal with rising electricity demand." A persistent criticism of EGAT is that it has paid scant attention to the demand side of the energy equation. Rather than build more carbon-powered plants, working to reduce demand and use existing supplies more efficiently has taken

287-641: Is a state enterprise, managed by the Ministry of Energy , responsible for electric power generation and transmission as well as bulk electric energy sales in Thailand . EGAT, established on 1 May 1969, is the largest power producer in Thailand, owning and operating power plants at 45 sites across the country with a total installed capacity of 15,548 MW. EGAT's monopoly position in Thailand's electrical energy market has been challenged by critics as influential as

328-846: Is sold to the Metropolitan Electricity Authority (MEA), which supplies the Bangkok region, and the Provincial Electricity Authority (PEA), which supplies the rest of Thailand. EGAT operates the Mae Moh coal (lignite) mine in Lampang Province and is required by its enabling legislation to sell lignite. Observers have noted that in some Western countries, the state purchases renewable energy from producers first before purchasing non-renewable energy. If renewables fail to meet

369-411: Is the site of a 2,400 MW lignite-fueled power plant run by EGAT. Coal-fired power plants such as Mae Mo can release up to 150 million tonnes of CO 2 over their design life of 20–25 years, according to Greenpeace-Thailand. The plant has been the target of a series of lawsuits brought by locals who claim that the lignite mining operation and the burning of lignite fuel by EGAT has negatively impacted

410-662: The Klong Saeng River . It took about one year to completely flood the 185 square kilometres (71 sq mi) basin. To flood this large area, 385 families of Ban Chiew Lan village were resettled. Rubber and other farming opportunities such as poultry, fruit orchards, vegetable farming, and reservoir fisheries were introduced together with the needed training programs and credit facilities to sustain farmers' incomes. Each family received 19 rai (7.2 acres [2.9 ha]) of rubber plantation as well as one rai (0.39 acres [0.16 ha]) for their dwelling. As part of

451-532: The World Bank halting funding for new coal projects except in "rare circumstances". Rachel Kyte, the World Bank climate change envoy, said continued use of coal was exacting a heavy cost on some of the world's poorest countries, in local health impacts as well as climate change, which is imposing even graver consequences on the developing world. "In general globally we need to wean ourselves off coal,...There

EGAT has been the target of several lawsuits brought by neighbours of several of its operations. The best known legal challenge took place in Mae Mo . Mae Mo

574-648: The Bangkok Electric Light Syndicate to generate and distribute electricity to the citizens of Bangkok. It was later sold as concession to Siam Electricity Co. Ltd., a Danish company led by Aage Westenholz which at the time also operated the trams . Its main power plant was located at Wat Liap near the Memorial Bridge and thus Wat Liap Power Plant became Thailand's first power plant. A succession of power companies with concomitant name changes followed. Siam Electricity Company Limited

For electricity provision in Thailand's other 74 provinces, it is supplied by the Provincial Electricity Authority . MEA maintains 18 district offices and 12 branch offices in its service area. Maximum demand for power peaked at 8,669 MW in 2014. In FY 2014 (1 October 2013 – 30 September 2014) MEA reported

656-628: The Krabi power plant will be delayed to 2024 from its original schedule of 2019. EGAT officials insisted that a new power plant is still needed in south Thailand to meet the region's power demands, which increase by four to five percent annually. In February 2018 the Ministry of Energy put the Krabi coal-fired power plant "on hold" for three years pending additional EHIA (environmental and health impact assessment) and EIA (environmental impact assessment) studies. In Songkhla Province 's Thepha District ,

697-436: The Krabi project. He directed that the public must be allowed to have its say. "A new power plant will certainly be built, but how? We have to take a look at what is good, safe and can deal with power shortages in order to ensure power security. There must be a balance between fossil fuels and recyclable energy," the prime minister said. The new assessments are expected to take at least two and a half years to complete, which means

738-689: The Metropolitan Electricity Authority Act 1958 (BE 2501). Its governor is Mr Somchai Roadrungwasinkul. The first recorded use of electricity in Thailand was the lighting of the Chakri Maha Prasat Hall of the Grand Palace on the occasion of the birthday of King Chulalongkorn on 20 September 1884. The king took a great interest in electricity, particularly its potential for street lighting. In 1897, Luang Pinitjakrapan and Leo Nadee established

779-574: The PDP: PDP2015 begins with the assumptions that: PDP2015 projects the following changes in Thailand electrical power generation fuel mix over the period 2014-2036: PDP2015 projects that Thailand's CO 2 emissions from power generation will rise from 86,998,000 tons in 2015 to 104,075,000 tons in 2036. Thailand's newest power development plan, PDP2018, is expected to be issued in September 2018. On December 3, 1991, The Cabinet of

820-686: The Royal Thai Government passed a resolution approving the establishment of the Demand Side Management Program (DSM) as a new department of EGAT. DSM’s mission is to promote the efficient use of electricity in Thailand . The first DSM program made its official debut on September 20, 1993 under the slogan “Together in Conservation”. Since then, EGAT has introduced the Energy Label No. 5 Project to

902-617: The bidding process, won by the Power Construction Corporation of China and Italian-Thai Development PCL. In November 2016, Prime Minister Prayut Chan-o-cha put the project "on-hold". According to the Bangkok Post , this is a move to "buy time". In early 2017, following a series of protests by those opposed to a coal-fired plant in Krabi, Prime Minister Prayut Chan-o-cha ordered that new environmental (EIA) and health impact assessments (EHIA) be conducted for

943-400: The capacity to produce or purchase 42,547 megawatts. Peak demand as of 31 April 2018 was recorded at 29,968 megawatts. Thus Thailand has a installed reserve margin of 58 percent. The "internationally accepted ideal reserve margin...[is] 15 percent of peak demand." EGAT continues to press forward with plans to construct six new coal-fired power plants by 2025 in spite of institutions such as

984-527: The compensation, the resettled people received 1,000 baht monthly per family. Resettlement drove the creation of basic public infrastructure, water supply systems, and public buildings such as schools, police station, medical center, and community hall—all built by the Thai government. A resettlement of animals took place by boat and helicopter to prevent them from drowning or starving on new created islands. In 18 months 1,364 animals of 116 species were rescued, but 44 died soon after. Many fish species died due to

1025-405: The country's energy demand, it is topped up using non-renewable energy sources. In Thailand, this policy is reversed. EGAT's net profits have declined 3.5 to 4 percent per year for the last several years, in concert with its share of power generation dipping to 36 percent in 2017 from 55 percent over a decade ago. Independent power producers (IPP) ramped up production over the last four years, from

1066-413: The court had ordered EGAT to return its Mae Mo golf course, adjacent to the open pit lignite mine, to woodland in order to help clean up the air pollution caused by EGAT's Mae Mo operations. Metropolitan Electricity Authority The Metropolitan Electricity Authority (MEA) ( Thai : การไฟฟ้านครหลวง ) is a Thai state enterprise under the Ministry of Interior . It was established on 1 August 1958 by

1107-475: The depletion of natural gas fields in the Gulf of Thailand . Opponents of the plan say their demands—which include a three-year waiting period to see if the province can produce 100 percent renewable energy—have been ignored. In August 2015, the prime minister ordered the formation of a commission composed of state agencies, EGAT, and citizen activists to find solutions to the power plant conflict. Gen Sakon Sajjanit

1148-802: The environment and the health of those living in the vicinity. A 12-year fight by villagers for compensation for damages ended in victory for the plaintiffs in February 2015. The Supreme Administrative Court in Chiang Mai Province upheld a ruling by the Chiang Mai Administrative Court in 2005. The court handed down a verdict ordering EGAT to pay compensation to 131 plaintiffs, some of them deceased. Plant victims were awarded between 20,000-240,000 baht each, commensurate with their suffering. The total amounts to 25 million baht plus 7.5 percent interest. Several days earlier,

1189-555: The first half of 2015. Indonesia and Australia supplied 5.6 million tonnes of bituminous coal and 5.5 million tonnes of "other" coal. China and Russia supplied 47,395 tonnes of anthracite coal . Thailand produced 6.88 million mt of lignite from January–May 2016, rising 7.5 percent from the same period in 2015. EGAT accounts for "...most of the country's domestic lignite production, which is mainly supplied to its own power plants." Coal-fired power plants consumed 10.31 million mt of coal and lignite from January to May 2016, or 60.9 percent of

1230-603: The government's plans to import up to 10,000 MW of electricity from Myanmar over the next two decades. Much of this electricity is expected to come from planned hydro-power projects on the Salween River ("Thanlwin" in Myanmar). Thailand and Myanmar have signed an agreement for the Salween dams project, five dams on the Salween and another dam on the Tenasserim River . EGAT has been pushing forward two projects:

1271-427: The hearing despite questions raised regarding his neutrality. He told the hearing that the project will benefit Thepa residents. "Since Egat has proposed the project, Thepha is now known nationwide. Shouldn't we be proud about that?" he said. Anuchart Palakawongse Na Ayudhya, director of EGAT's Project Environment Division, insisted EGAT's hearings were lawful. "We have organised the public review step by step according to

1312-497: The law," he said. Anuchart said EGAT did not bar anyone from expressing their opinions. "It's impossible to cancel the project. Most Thepha people support it," he said. On 17 August 2017, an expert committee of the Natural Resources and Environmental Policy and Planning Office (ONEP) approved the 2,200-megawatt coal-fired power plant's EHIA, removing one of the last hurdles to the plant's construction. The EHIA's approval

1353-416: The plant who say that it would endanger Krabi's relatively pristine environment. EGAT has pushed forward with development despite not having completed an environmental impact study. It intends to start the bidding process without an environmental assessment in order to "save time". The Krabi site is one of nine coal-fired plants planned for southern Thailand to be constructed over the next two decades to off-set

1394-549: The remainder. While EGAT pushes forward with plans for coal-fired generating plants, many countries are spurning coal or deferring its use: Guiding EGAT's efforts is Thailand's Power Development Plan (PDP). The plan, prepared by the Ministry of Energy (MOE) and EGAT, is issued iteratively. The previous edition, PDP2010 Revision 3, covered the years 2012-2030. Along with the PDP, the MOE produces several subsidiary plans that roll up into

1435-446: The stagnant water conditions. The average depth of the lake is around 40 m (130 ft) while the deepest point of the lake was estimated to be around 90 m (300 ft) deep. The national park area is inhabited by a range of mammals such as tigers , elephants , tapirs and many monkey species. Birds such as hornbills , banded pittas, and great argus are as well forest residents. Less commonly seen reptiles include

1476-418: The total, rising 11.4 percent year on year. In 2017, Thailand imported 22.18 million mt of coal, up 2.5 percent from 2016. The nation produced 16.26 million mt of lignite in 2017, down 4.2 percent year on year. The country consumed a total of 39.07 million mt of coal and lignite, up 0.9 percent. Coal-fired power plants consumed 23.73 million mt of the total, down 4.2 percent from 2016. Other industries consumed

1517-468: The use of electricity from ironing. Cloth products started to be labeled with Label No. 5 in January, 2018. Several critics have pointed out that EGAT's in-house generating capacity coupled with its power purchases from other suppliers has resulted in excessive reserve capacity. One such critic has been the editorial board of the Bangkok Post . They point out that in May 2017, Thailand's peak power demand

1558-530: Was 28,578 MW. Total EGAT installed and purchased power capacity in May 2017 was 41,903 MW, leaving a reserve power capacity of 13,325 MW, 46 percent of total May demand. Industry standard best practice is that a 15 percent reserve power capacity is sufficient to "...maintain a stable power supply." In July 2017, EGAT generated 16,071 MW and purchased 25,652 MW from other suppliers for a total of 41,723 MW. Updated figures reported in June 2018 indicate that Thailand has

1599-491: Was appointed committee chairman. It was agreed that the government put a hold on consideration of the Environmental Impact Assessment and Environmental Health Impact Assessments; that EGAT postpone bidding for the plant and the seaport; and that all parties allow Krabi to try to produce 100 percent renewable energy for three years with government support. EGAT broke the agreement as it proceeded with

1640-638: Was met with renewed criticism. The Bangkok Post commented that, "These...assessments turn out to be just another rubber stamp for operators — in this case...EGAT...." ONEP responded to criticism by defending its approval. A construction schedule has not yet been published. In February 2018 the Ministry of Energy put the Thepha coal-fired power plant "on hold" for three years pending additional EHIA (environmental and health impact assessment) and EIA (environmental impact assessment) studies. Thailand's Power Development Plan, approved in May 2015 (PDP 2015), outlines

1681-639: Was one such early power company. In 1939 its name was changed to Thailand Electricity Corporation Company Limited. In 1950 its concession expired and it was taken over by the government, renaming it Bangkok Electricity Authority, operating under the aegis of the Interior Ministry. On 1 August 1958 the Metropolitan Electricity Authority (MEA) was established by merging the Bangkok Electric Works and
