San Miguel Corp. (SMC), through its power generation arm SMC Global Power Holdings Corp, on Thursday said it is spending over $1 billion to simultaneously build 31 new battery energy storage facilities nationwide, with a rated capacity of 1,000 megawatts.
“Our ongoing investment into battery energy storage facilities will greatly benefit power consumers all over the country, because this will mean that even faraway provinces or areas, can have the same stable and good quality power supply as everywhere else,” SMC president Ramon Ang said in a statement.
“This means that provinces and islands will have better and more equal opportunities for industrialization and economic growth. If previously some areas could not attract investments because of unstable or poor power supply, battery energy storage will make power supply more stable and reliable. Battery storage will significantly reduce imbalances in the grid that cause power interruptions and brownouts,” Ang said.
SMC Global Power completed in 2018 the very first battery energy storage facility in the country in its power plant in Masinloc, Zambales.
The company has since embarked on a project of “such historic scale” using a relatively new technology.
The technology, Ang said, is capable of improving power quality throughout the grid system and facilitate integration of renewable power sources into the country’s generation portfolio.
He said that some of its battery energy storage facilities are now in the advanced stages of completion.
The facilities, which will make up the company’s total committed capacity of over 1000 MW, will be located in several strategic sites from Luzon to Mindanao where power quality mitigations are required.
The technology is also a major step towards making intermittent renewable energy more viable in the country, the SMC chief said.
Ang said that the technology will boost flexibility of the country’s power grid and improve power quality by removing excess power and injecting required power at strategic areas within the grid within millisecond level.
This ensures power quality is maintained and that it reaches power users all over the country.
“This can even support equal-opportunity industrialization in many provinces where historically, no industrial plants would locate because of poor power quality,” Ang said.
On top of that, he said that battery energy storage facilities can facilitate the integration of renewable energy sources such as wind or solar into the grid.
“Our country’s challenge with renewables is that it is intermittent, because of its nature. But with strategically located battery storage facilities, this can be mitigated and renewables can become more viable. This will help the transition to more renewable sources of energy in the future,” Ang said.
The immediate aim though, is to address power quality issues.
The battery energy storage projects will be used as regulating reserve type of ancillary service for the country’s major power transmission firm, National Grid Corp. of the Philippines (NGCP), to specifically mitigate grid frequency fluctuation and voltage issues, according to SMC. -MDM, GMA News
