Background

The project is being developed by Hongsa Power Company, a consortium comprising the Thai company Ratchaburi Electricity Generating Holding Public Company (Ratch), Banpu Power (a susbidiary of the the Thai coal-mining company Banpu) (BPP) and Lao Holding State Enterprise (LHSE). Ratch and BPP each have a 40% stake in the project and LHSE 20%.[1]

The power station is proposed as a mine-mouth power station. The power station and associated mine are slated to cost US$4 billion. The consortium has been granted a 25 year concession over a 60 square kilometre site.[1]

Under the terms of a May 2009 agreement 1,473MW will be exported to the Electricity Generating Authority of Thailand (EGAT) with 100MW for domestic Lao consumption. (The remainder is for on site use).[1]

In August 2014 LHSE said generator units 1 and 2 would begin electricity generation in 2015 and unit 3 in 2016.[2]

The first unit began operating in June 2015, and will be solely exported to the Electricity Generating Authority of Thailand (EGAT) through a 500-kilovolt power grid system stretching over 67-km. The second unit is planned to begin commercial generation in November 2015 and the third in March 2016.[3]

Unit 2 began operating on November 2, 2015.[4] Unit 3 was synchronized in December 2015,[5] and began commercial operation in March 2016.[6]

Unit 4

In May 2015 Ratch president Phongdit Potchana said the company planned to add a fourth unit to the plant. According to Phongdit, mining partner Banpu Plc had estimated 577 million tonnes of lignite reserves, more than the 371 million tonnes needed for the 25-year operation (2016-2014) of the first three units.[7]

However, in November 2016 the Laos government said it planned to delay a decision on developing the fourth unit for a decade or so. Officials said they want to formulate a clearer policy to develop the country's power sector before making any decision, and determine if there is enough domestic lignite coal to power the unit.[8]

History

In 1996, Thai Lao Power Co. Ltd. (TLL) initiated the proposed development at HongSa District, Laos PDR. The project is to be comprised of a coal mine, power plant and transmission line.[9]

It is reported that the project comprises of a large open pit lignite mine which will supply fuel for a power plant consisting of three (3) 626 MW (gross) generating units. Water supply for the power plant will be from 2 reservoirs on Nam Louak (upstream of Muang Hongsa) and Nam Kene (downstream of Muang Hongsa). A double circuit 500 kV transmission line will also be constructed.[10]

Community resistance

In May 2013 it was reported that authorities in northern Laos had barred non-governmental organizations from meeting with villagers being relocated for the plant. The NGOs said they are trying to inform residents about their compensation rights and the full impact of the project.[11] Nearly 2,000 people were moved to new locations.[12]

Finance

According to the Hongsa Power website, "A total finance package worth US$3.71 billion in capital commitments to HPC was proportionately contributed by 9 Thai commercial banks – namely, Bangkok Bank, Siam Commercial Bank, Krungthai Bank, Government Savings Bank, Kasikornbank, Export-Import Bank of Thailand, Bank of Ayudhya, Thanachart Bank, and TMB Bank. As for long-term senior debts under the typical limited-recourse project financing scheme, the financial close took place in August 2010; while the first drawdown was made in October 2010. In addition to senior loan facilities, shareholders are committed to back-end equity injection."[13]
