Ingrid Power Holdings Inc., a joint venture of ACEN Corp. and Axia Power Holdings Philippines Corp., plans to put up a 270-megawatt battery energy storage system in Barangay Malaya, Pililla, Rizal that will cost nearly P7 billion.
IPHI said in a report to the Department of Environment and Natural Resources the project would address the need for energy storage systems to handle the ancillary or reserve requirement of the power grid.
It said the Pililla BESS would be operated with energy time-shifting or energy arbitrage as its primary function. The plant will charge from the grid when there is excess energy and electricity marginal prices are low.
The stored energy will then be discharged and sold to the grid during high-power demand and high electricity market prices.
The charging and discharging from the grid will be via the 230-kilovolt Malaya Substation of the National Grid Corp. of the Philippines through a direct connection to the Ingrid Substation.
It will serve as a source of ancillary service for the Luzon grid and improve power quality to help ease the frequency and voltage problems. The project will also provide ancillary service in the form of regulating and contingency reserve to maintain the consistent grid frequency.
IPHI said the project would use lithium-ion battery energy storage systems, which have better ageing and cycle life characteristics and are used mainly for energy time-shifting.
These batteries allow convenient installation and are easily scalable for future expansions. They also have relatively high specific energy, energy density and specific power.
IPHI said this technology is safe to operate and has a minimal environmental impact during construction and operation.
The project will rise on 63,151-square-meters property and will have a service lifetime of 15 years. The proposed project site is owned by Tabangao Realty Inc. and leased by Buendia Christiana Holdings Corp.
