The Dinginin power project is a 1.3GW supercritical, coal-fired power project located in the Bataang Peninsula of Philippines.

GN Power Dinginin Company, a joint venture between AC Energy and Aboitiz Power, which is a subsidiary of Therma Power and Power Partners is developing the coal-fired power facility with an estimated investment of £1.11bn ($1.7bn).

While the construction works were started in September 2016, the first unit of the plant was connected to the grid in February 2021.

The plant is expected to commence full-fledged operations with the commissioning of the second unit in the second quarter of 2021.

Location and site details

The Dinginin coal-fired power project is located at the entrance of Manila Bay, in Dinginin, approximately 5km away from the Mariveles city, in the Bataan Peninsula of Philippines.

The project site covers approximately 60ha and lies adjacent to the 600MW Mariveles power plant.

Dinginin power plant make-up

The Dinginin power project comprises two supercritical, pulverised coal-fired units of 668MW capacity each. Each block is equipped with flue gas desulphurisation (FGD) system to control emissions.

The other components of the plant include high-pressure and low-pressure heaters, distributed control system (DCS), transformers, circuit breakers, gas insulated switchyard, dual optical ground wire power transmission cable, coal mills, coal handling system, auxiliary seawater cooling water pumps, and condensate water pumps.

The project utilises an 80,000t coal terminal, along with two 120m-diameter circular coal yards.

Power evacuation

The electricity generated by the Dinginin coal-fired power project will be evacuated to the grid through a double-circuit 500kV power transmission line.

Contractors involved

Shanghai Electric Power Construction Company (SEPCC) was awarded an engineering, construction and procurement (EPC) contract for the Dinginin power project in October 2015, while China Electric Power Construction Company was engaged as the construction contractor.

Dongfang Boiler Company manufactured and supplied the deaerator equipment, while Alstom supplied the steam turbine generators, which were delivered at the site by Royal Cargo.

Henan Electric Power Survey and Design Institute was engaged for the survey, design and engineering of the coal-fired power project.

Third Aviation Institute was contracted for the design and construction of the coal unloading terminal and sea water intake system in November 2016.

Arint Consulting Services was contracted for maintenance and spares services of the main plant and the balance of plant system in December 2018.

Black and Veatch was contracted for technical advisory and owner’s engineer services of the coal-fired power project

Miescor was contracted for the construction of the 500kV transmission line, while Xiamen ABB Company supplied the 500kV gas-insulated substation (GIS) and associated equipment.

Milbank was engaged for financial advisory services of the coal-fired power project in December 2017.

Dinginin power project background

GN Power Dinginin Company was established for the development of the 1.3GW coal-fired power project in 2014. The company achieved financial closure for the first unit in December 2015, while the project financing for the second unit was closed in December 2018.

The Dinginin coal-fired project intends to support the electricity demand of the Luzon and Visayas regions.

It is the first supercritical thermal power plant in Philippines, and its development is being supported as  part of China’s One Belt One Road (OBOR) strategy.
