The National Grid Corp. of the Philippines has contracted the geothermal facilities of Green Core Geothermal at Palimpinon and Tongonan for three years.

In the Philippines, the country’s “National Grid Corp., operator of the country power transmission system, has contracted the geothermal facilities of Green Core Geothermal Inc., a unit of Aboitiz Power Corp., to provide ancillary services.

Under the agreement, the grid operator would source power from Green Core’s Palimpinon and Tongonan geothermal facilities in Leyte for three years.

“The current levels of available ancillary services in the Visayas Grid are significantly insufficient to meet the required levels,” the firms said in a joint filing before the Energy Regulatory Commission.

“Thus, at present, the transmission of power in the Visayas Grid cannot be considered reliable, stable and secure,” they added.

Ancillary services refer to power supplier-driven services that are necessary to support the electricity transmission from power resources to load customers to maintain the stability, reliability and quality of power services.

“As the demand for power in the Visayas increases, the requirements of the system to ensure stability, reliability and security likewise increase,” the firms said.
