AES PH plans 250MW storage facilities

0

AES Philippines Power Partners Co. Ltd., a subsidiary of US power giant AES Corp., is planning to build energy storage facilities across the country that can store up to 250 megawatts (MW) of reserve power.

Neeraj Bhat, AES Philippines managing director, said they are still studying the possible locations of the storage facilities.

“We see 200-250MW of energy storage [facilities]that will be put up around the country. We’re looking at options across Luzon, Visayas and Mindanao,” Bhat said.

The technology involves constructing a battery storage system that absorbs electrical energy during periods of supply surplus and stores it for use in periods of low supply in the grid.


The Department of Energy (DOE) explained that the battery storage project is a new technology using rechargeable cells that can be tapped for ancillary services or reserve power.

To turn the plan into reality,Bhat said they need help from government regulators to push it forward.

“What we really need is the regulatory leadership to help push these projects through and, of course, [cooperation]from the grid operator,” he said.

Bhat cited the company’s 40-MW battery storage project in Kabankalan, Negros Occidental that is facing because they are still waiting for the National Grid Corp. of the Philippines (NGCP) to provide some guidance on the ancillary service procurement agreement.

“We’ve asked them for that some time last year,” he added.

The AES has sent a proposal to NGCP as ancillary services provider. Records from the DOE show that the AES battery storage project was originally targeted to come online by March 2015.

“Generally, Visayas has no ancillary services today. It needs about 80MW 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 world leader in commercial energy storage partnerships, which enable utilities, power markets and renewable developers to manage projects from concept to operation.
