At its original capacity of 75 MW, the Ambuklao Hydroelectric Power Plant is one of the first and oldest large hydroelectric power plants in the Philippines. Constructed in 1950 and completed in 1956, the facility runs along the upper portion of Agno River.

In 2007, SNAP won the bid for the Ambuklao-Binga hydroelectric power complex for $325 million. The bid consists of Ambuklao and the 100 MW Binga Plant. The plant had been shut down and put under preservation since 1999 due to damage from the 1990 earthquake. After rehabilitation and upgrading, Ambuklao Hydro was re-opened in 2011 as a 105 MW power plant.

The Binga Hydroelectric Power Plant was built in 1960 and lies 19 kilometers downstream of its sister facility, Ambuklao. SNAP won in 2007 the public bid for Binga and Ambuklao, which were sold as a package under the power sector privatization program of the Philippine government, for $325 million. Only the power plant components were privatized while the dams remain government-owned. 

Binga Hydro underwent refurbishment in 2010 and was completed in 2013. This refurbishment increased the Binga plant’s capacity from 100 to 125 MW. It is now capable of generating up to 140 MW after further upgrading.

As one of Luzon’s largest hydro facilities, the Magat Hydroelectric Power Plant houses a maximum output of 388 MW, drawing power from the Magat river through the multi-purpose Magat dam.

The national government began the dam’s construction in February 1980 and completed the commissioning in Dec 1983. Under the Electric Power Industry Reform Act (EPIRA), it was later subject to privatization in 2006. 

Following a successful bid of $530 million, SNAP took over operations on April 26, 2007. Only Magat dam’s power components were privatized. Its re-regulating facilities downstream are owned and maintained by the National Irrigation Administration (NIA).

Maris Hydro is the first power plant constructed by SNAP since it acquired Magat Hydro in 2007 through privatization. Construction of the P2.15 billion run-of-river hydro plant took about two years – it broke ground in late 2015 and was completed in November 2017. Maris Hydro utilizes the water coming from the Magat River that goes into the Maris re-regulating dam located downstream of Magat, before flowing into the Maris Main (South) Irrigation Canal.

The Maris Hydro project was proposed by SNAP-Magat’s operations and maintenance team under the company’s business creativity and innovation program. It was then developed and implemented by the business development group and later turned over to SNAP-Magat for operation.
