Hydroelectric Power in the Philippines

Updated on September 4, 2013

Making Water Work for the Common Good

The Philipppines have pursued a mulitipurpose hydroelectric power system strategy in designing . For example, the San Roque dam has a capacity of 85 MW, which is the basis for the capacity payments under the PPA. The balance is surplus power that reduces dependence on imported fuel oil and also lowers the variable operating expenses of other power plants. This offers substantial power benefits in addition to the peaking capacity and energy analysis and provision. Most of these benefits are unique to large hydroelectric facilities.The Lake Lanao facility (watershed diagrammed on left) also is a peaking/irrigation facility.

Lake Lanao

Link to Wikipedia article on Lake Lanao

The lake was formed by a large volcano collapsing and damming a basin between two mountain ranges The lake is fed by four rivers. It is the deepest lake in the Philippines.The lake is a home of myths and legends of the Maranao tribe: their name means "the people living around the lake".

The Agus River, which flows out of the lake into Iligan Bay viathe Maria Cristina Falls and the Linamon Falls.

A hydroelectric plant installed on the Agus outflow from Lanao Lake generates 70% of the electricity used by the people of Mindanao.

Angat Dam

(A Francis turbine runner, bound for the Grand Coulee Dam in the USA. The Angat Dam has vertical shaft turbines - the water falls from the dam surface inputs downward through the turbine)

Angat Dam is a concrete water reservoir embankment hydroelectric dam that supplies the Manila metropolitan area water. It was a part of the Angat-Ipo-La Mesa water system. The main powerhouse has 200,000 kW (4 X 50,000 kW) installed capacity while the auxiliary powerhouse has 46,000 kW (3 X 6,000 kW, 1 x 10,000 kW, 1 x 18,000 kW) installed capacity, providing a total of 246,000Kw.The power is generated by 10 Vertical shaft, Francis turbines

Mangat Dam

Magat Dam is a large rock-fill dam located on Magat River, a major tributary of Cagayan River. Construction of the dam started in 1975 and completed in 1982. Magat Dam has two primary purposes: as a source of irrigation water and as a provider of hydroelectric power. The power plant is a four-unit powerhouse with a rated capacity of 360 megawatts It only operates when there is a high demand for electricity in the Luzon power grid, to which the plant is connected] The water stored in the reservoir is enough to supply about two months of normal energy requirements.

San Roque Dam

The San Roque Dam, operated under San Roque Multipurpose Project (SRMP) is a massive gated spillway of 200 meters height, 1.2 kilometer length embankment dam on the Agno River , nearly 200 km north of Metro Manila. The dam icreates a reservoir with a surface area of about 12.8 square kilometers. Each wet season, the run-off is stored for later release via water turbines to generate power and irrigate crops.

The dam has a capacity to generate 345 megawatts (MW). It operates primarily as a peaking plant during periods each day when the electrical output of base and inter-mediate load power plants cannot fulfill consumer demand.
