AES Philippines Power Partners Co. Ltd., a subsidiary of US firm AES Corp., has secured the approval of the Department of Energy (DOE) to conduct a grid impact study on three proposed power projects with a combined capacity of 120 megawatts (MW).
These projects include the 40-MW Masinloc coal power plant in Masinloc, Zambales and two battery energy storage plants in Toril, Davao del Sur and Maco, Compostela Valley with 40-MW capacity each.
The two battery storage facilities are part of the company’s plan to put up 200 to 250MW of storage facilities across the country.
A battery storage system absorbs electrical energy during periods of supply surplus and stores it for use in periods of low supply on the grid.
The DOE explained that the battery storage project is a new technology using rechargeable cells which will be used for ancillary services.
Neeraj Bhat, AES Philippines managing director, earlier said they need help from government regulators in order for these projects to materialize.
He cited the company’s 40-MW battery storage project in Kabankalan, Negros Occidental which has been delayed because they are still waiting for the National Grid Corp. of the Philippines (NGCP) to provide them some guidance on the ancillary service procurement agreement.
AES has sent a proposal to NGCP to become an ancillary services provider.
Records from the DOE showed that AES’ battery storage project was originally targeted to come online by March 2015.
“Visayas has no ancillary services today. It needs about 80 MW frequency regulation, just a primary service we’re looking to provide,” Bhat said.
The energy storage solutions of AES allow customers to unlock value from existing power infrastructure by liberating reserve capacity, enabling renewable facilities to generate new revenue streams, improving flexibility and reliability of the power system, and meeting peak power demand.
AES Corp.’s subsidiary, AES Energy Storage, is a leader in commercial energy storage partnerships, which enable utilities, power markets and renewable developers to manage projects from concept to operation.
