Ingrid Power Holdings Inc. plans to put up a 150-megawatt battery energy storage system in Barangay Malaya, Pililla, Rizal with estimated construction cost of P6.875 billion.
Ingrid is the special purpose vehicle of AC Energy Inc. and Axia Power Holdings Philippines Corp., a subsidiary of Marubeni Corp. of Japan. The project is in response to the call of the Department of Energy (DOE) in 2019, which released a department circular providing a framework for energy storage system in the electric power industry.
The circular provides guidelines on how energy storage systems (ESS), being an emerging technology, “may be utilized to improve the electric power system to ensure quality, reliability, security and affordability of the electric power supply of electric power.”
An ESS may be registered to provide ancillary services; provide energy through bilateral supply contracts or trading in the Wholesale Electricity Spot Market; and for the management of the penetration of renewable energy.
Ingrid said in documents submitted to the Department of Environment and Natural Resources that the project would use lithium-ion BESS which has better ageing and cycle life characteristics and is primarily used for energy time-shifting.
“Being primarily offered in containerized solutions, these batteries allow convenient installation and are easily scalable for future expansions. Among the most mature and commercially available battery technologies in the market, lithium-ion batteries have relatively high specific energy, energy density and specific power. This technology is also safe to operate and has minimal environmental impact during construction and operation,” the company said.
