Houay Por Dam Hydropower Info - by Hobo Maps - Go to Hydropower Projects Page - - - Home

Houay Por Hydropower project is located along the Houay Por and Xeset rivers in Lao Ngam District, Saravan Province, southern Lao PDR. The project is downriver and not far north of the Xeset 1, 2 and 3 hydropower projects on the XeSet (river).

Houay Por Hydropower project is sometimes also known as Xeset Downstream HPP.

The project has a diversion dam that diverts water flow from the Xeset river along 6 km of open channels into the Houay Por Hydropower project to take advantage of a water head of 64 meters.

Houay Por diversion dam images below located at coordinates - 15°32'37.8"N 106°15'39.0"E (15.543828, 106.260821) near Ban Saenvang and National Road 20.

Installed capacity is 15 MW from 4 sets of Horizontal Francis Turbine Generators - 2 sets at 5 MW each and 2 sets at 2.5 MW each

Annual capacity output is estimated at 60 GWh.

The project construction started in February 2015, was completed in July 2017 and has been in operation since 2018.

Electricity du Laos (EDL) is the offtaker of the output for domestic consumption within Laos.

The project owner is Huai Por Power Co., Ltd. (also spelled Houay Por Power Co. Ltd.)

Huafei (Huefai) Energy Investment (Chinese Co.) may be a major shareholder (not confirmed)

Khounkham Group was involved in the construction.

Project cost: $ 24.3 million US.

A head pond along the open diversion channels is used for temporary water storage to regulate a constant flow into the 1 km-long penstock just above the powerhouse.

A 2 km-long open tailrace channel carries discharged water from the powerhouse back into the XeSet river.

The project includes a concrete gate dam, trapezoid open channel, concrete core earth rock-fill auxiliary dam, open fore bay, penstock, ground workshop, power house and tailrace.

The main dam is 12 meters high and 98 meters long with a small reservoir capacity of 76,000 cubic meters.

The secondary dam is 7 meters high and 217 meters long with a tiny reservoir capacity of 3,800 cubic meters. The water flow rate is 29 cubic meters per second.

Penstock pipe diameter is 3.5 meters with a length of 990 meters
