Profitability however is a main concern now because it is in the business of missionary electrification that provides electricity to far-flung, off-grid remote areas and islands at subsidized rates.

It also manages 17 large dams and 11 watersheds in the country and continues to oversee the privatization of the government's remaining undisposed power assets.

The law nationalized the hydroelectric industry and reserved for the use of NPC, all streams, lakes and springs in the Philippines where power may be developed, subject to existing rights.

Under the revised charter, the activities and functions of the corporation were decentralized and carried out by three regional offices to be established in Luzon, Visayas and Mindanao.

With the government's aim of promoting the economic welfare of the country through the attainment of total electrification, especially in rural areas, Presidential Decree No.

The NPC, as the authorized implementing agency of the state, was entrusted with the responsibility of setting up transmission line grids and the construction of associated generating facilities in Luzon, Mindanao, and major islands of the country, including the Visayas.

The move was intended to make the NPC a more efficient implementing arm of the government in the conservation and utilization of water resources and in the total electrification of the country.

Marcos requested that National Power Co. (the government owned electric utility) negotiate a deal to buy two nuclear reactors.

The final construction cost reached to $2.2 billion for a single reactor producing half the power of the original proposal.

Many problems identified in earlier stages remained throughout construction, as reported by inspectors, though all these were denied by Westinghouse to save their company's image.

40, the National Power Corporation was authorized “to own and operate, as a single integrated system, all generating facilities supplying electric power to the entire area embraced by any grid set up by NPC.” Contemplated to be integrated in the system were all Meralco generating units, and thus began a long drawn-out negotiation for the sale and turnover of these units to the government at terms and conditions acceptable to all parties.

Finally, on June 11, 1978, such negotiation reached a successful climax with the signing of a contract between the government and Meralco for the purchase of the latter's power-generating units at a total cost of ₱1,100 million.

Virata, representing the government, and Cesar C. Zalamea, chairman of Meralco, with Energy Minister and NP Board Chairman Geronimo Z. Velasco, Energy Deputy Minister and NPC President Gabriel Y. Itchon, IBP Assemblyman Emilio M. Abelo, Sr. and Meralco Treasurer Antonio Ozateta as witnesses.

Such centralization is aimed at providing energy throughout the Philippines and building up additional generating capacity for electricity in pursuance of the government objective of total electrification of the country.

Through the years, the composition of the government panel underwent several changes brought about by retirements from service, shifts in assignments and appointments of technical men.

This culminated in the signing by end-1988 of a BOT agreement between the NPC and Hopewell Energy Management Limited of Hong Kong for the Installation of the two 110-megawatt turbine plants in Luzon.

For such ambitious plan, NPC envisioned the interconnection of all-independent grids in Luzon, Visayas and Mindanao through the advanced system of overhead lines and submarine cables.

The 18.3 km (11.4 mi) submarine cables interconnecting the two islands enable NPC to utilize the excess steam from the Palimpinon Geothermal power plant in Negros.

In addition, the state-owned power firm installed 768 diesel generator sets (with a total capacity of 19.7 KW) to serve the consumers in isolated islands – in line with NPC's mission to bring the benefits of electricity to the farthest corners of the country.

Guido Alfredo A. Delgado, a banker, assumed the post of NPC president at oath taking rites held in Malacañang on September 28.

He succeeded Dr. Viray who was designated Secretary of energy, vice former NP Board Chairman Delfin L. Lazaro who opted to retire from government service.

National Power is no longer the same corporate entity, with the EPIRA mandating the privatization of its generation and transmission assets, save for those necessary for missionary electrification.

The following year, NPC was able to install 12,718 kW of new capacities in 34 SPUG areas nationwide, from as far north as Cagayan down to Basilan and Sultan Kudarat in southern Philippines.

This was done in support of the DOE's Rural Area Electrification Subsidy (RAES) program which was aimed at providing basic electricity service in remote barangays through solar home systems, PV battery charging stations, micro-hydro, wind energy, diesel and hybrid facilities.

But it was able to complete the PRES project in Masbate, with all of the 154 power plants and 5,219 solar home systems installed and in commercial operation.

In 2012, a total of 11,300 kW of additional rented capacity was installed in 8 Diesel Power Plants in Batanes, Aurora, Palawan, Romblon, Masbate, Siquijor, Basilan, and Sulu.

At the same time, NPC continuously updates its dam safety protocols and flood control programs in keeping with international best practices.
