The National Power Corp. (Napocor) divulged its plans on constructing four more solar photovoltaic (PV)-diesel hybrids in far-flung villages and islands in the country.
Napocor President and Chief Executive Officer Pio Benavidez said in a statement on Wednesday the state-run corporation aims to replicate its hybridization project in Limasawa and in other parts of the country.
“For this year, we aim to duplicate the success of our Limasawa Solar PV-Diesel hybridization in Limasawa Island, Southern Leyte, to four other areas such as Cuaming, Bohol (55 kilowatt peak, or kWp); Palumbanes in Catanduanes (40 kWp); Sabtang in Batanes (250 kWp); and Itbayat in Batanes (250 kWp),” Benavidez said.
Benavidez said Napocor’s 2021 to 2025 Missionary Electrification Plan provides a framework of how renewable energy, particularly solar hybrid, will be implemented and integrated to its existing Small Power Utilities Group (SPUG) areas for the next five years.
To recall, in 2019, Napocor switched on its pilot solar PV-diesel hybrid power plant and was synced to the Limasawa Diesel Power Plant in February last year.
Since then, the state-run firm said there had been a reduction of the cost of electricity by an average of 0.97 centavos per kilowatt-hour and recorded fuel savings of about 31,000 liters of diesel with an estimated amount of P970,000.
Napocor noted both calculations were based on the actual fuel consumption and delivered price. It does not include the fixed operating costs of the power facility.
Based on the projected operation of Limasawa DPP for the next five years, the estimated average fuel savings is 45,800 liters per year, which is equivalent to P1.75 million per year.
From a long-term perspective and considering the increase of fuel price and decrease of power production of the solar PV and its battery system, the hybrid system will reduce the cost of electricity at an average of P1.33 per kilowatt-hour and will allow an average diesel fuel savings of 38,700 liters per year.
There would also be a reduced carbon dioxide emission at 101,820 kilograms per year, it added.
“With these promising developments and in response to the DoE’s (Department of Energy) strategic directive of promoting a low carbon future, Napocor will be more proactive in building and integrating renewable energy in our SPUG areas,” Benavidez said.
Under Republic Act 9136, or the “Electric Power Industry Reform Act of 2001,” Napocor is tasked to perform missionary electrification in the farthest communities and islands.
It is in this capacity that the corporation operates 276 SPUG plants in 189 municipalities across 35 provinces in the country.
