Natural Gas

Natural gas is the cleanest-burning of all fossil fuels, emitting up to 60% less carbon dioxide than coal. It also does not leave behind by-products like ash, sludge, and other particulate matter that are harmful to our health and the environment.

First Gen has four (4) natural gas-fired power plants: the 1000-MW Santa Rita, the 500-MW San Lorenzo, the 97-MW Avion and the 420-MW San Gabriel power plants. Santa Rita, San Lorenzo, and San Gabriel deliver baseload power, while Avion capitalizes on the growing demand for peaking power in the Luzon grid.

Santa Rita Combined-Cycle Natural Gas-Fired Power Plant

Owned and operated by First Gen’s subsidiary, First Gas Power Corporation (FGPC), the Santa Rita plant is a 1,000-MW combined-cycle natural gas-fired power plant. Located in the First Gen Clean Energy Complex in Batangas City, its operations commenced in August 2000. It uses natural gas from the Malampaya gas field in offshore Northwest Palawan, and can also utilize condensate, distillate, and naphtha as back-up fuel. Operations and Maintenance (O&M) of the plant is performed by Siemens Power Operations, Inc. (SPOI),a wholly-owned subsidiary of Siemens AG.

Santa Rita sells its electric output to Meralco under a 25-year Power Purchase Agreement (PPA) with an 83 percent take-or-pay Minimum Energy Quantity (MEQ) arrangement.

San Lorenzo Combined-Cycle Natural Gas-Fired Power Plant

Owned and operated by First Gen’s subsidiary, FGP Corp. (FGP), the San Lorenzo plant is a 500-MW combined-cycle natural gas-fired power plant that is located west of, and adjacent to, the Santa Rita plant. The plant commenced commercial operations in October 2002.

Similar to Santa Rita, San Lorenzo sells its electric output to Meralco under a 25-year PPA with an 83 percent take-or-pay MEQ arrangement.

Avion Open-Cycle Natural Gas-Fired Power Plant

The 97-MW Avion open-cycle natural gas-fired power plant, which started commercial operations on September 26, 2016, was developed by First Gen’s wholly-owned Prime Meridian Powergen Corporation (PMPC). The plant is located in the First Gen Clean Energy Complex in Batangas City.

Avion uses two units of General Electric’s LM6000 PC Sprint aero-derivative gas turbines, making it the first power plant in the Philippines to run on aircraft engines for land-based power generation application. The Avion power plant has the capability to run on either natural gas or diesel, and its turbines have the flexibility to ramp up quickly and to do unlimited daily starts and stops, making it the ideal merchant peaking plant in First Gen’s portfolio of assets.

Half of Avion’s capacity is contracted under a firm Ancillary Services Procurement Agreement (ASPA) with the National Grid Corporation of the Philippines (NGCP). Avion’s flexibility allows it to provide ancillary services to the grid which is integral to ensure the stability and reliability of the power grid. The other half of Avion’s capacity is sold to the Wholesale Electricity Spot Market (WESM) in order to take advantage of high clearing prices, particularly during peak periods. Avion can also offer this capacity as ancillary services to NGCP on a non-firm basis.

San Gabriel Combined-Cycle Natural Gas-Fired Power Plant

First Gen’s wholly-owned First NatGas Power Corp. (FNPC) owns and operates the 420-MW San Gabriel Power Plant, which is the most efficient natural gas-fired plant in the Philippines.

San Gabriel started commercial operations on November 7, 2016, and is located in the First Gen Clean Energy Complex in Batangas City.

San Gabriel utilizes Siemens’ SCC6-8000H combined-cycle gas turbine, which is designed to offer operational flexibility.

In 2018, San Gabriel started selling its full capacity to Meralco under a six-year power supply agreement.
