The economics of rural electrification using microgrids should be considered an investment for the future, akin to how Silicon Valley tech providers plough money into initially loss-leading products and services, the chief of developer and manufacturer Solar Philippines has said.
Last week, Tom Kenning, deputy editor at our sister site PV Tech, wrote an extensive and in-depth blog from a field visit to Paluan on the island of Mindoro, where a Solar Philippines offshoot company, SPSB (Solar Para Sa Bayan – ‘Solar for the country’), has executed a microgrid project that brings power to about 3,000 customers. The microgrid, which uses solar, batteries and diesel backup, is also anticipated to slash commercial electricity costs by half for local businesses.
From having just 3-8 hours of usable electricity each day, with a connection to a 5MW diesel plant some 30km away disconnected a decade ago due to transmission issues, the villagers will be able to run their homes and businesses from the new 2MW PV and 1.8MW / 1.5MWh energy storage plant, coupled with 1,260kW of diesel generation.
Solar Philippines has aggressively set about developing and executing large-scale and microgrid projects in the country as well as establishing PV module manufacturing capabilities. Company chief Leandro Leviste, son of a prominent senator, is enthusiastic about microgrids, while all of the local residents PV Tech spoke with seemed similarly enthused about the endeavour.
Leviste said that the downward trajectory of battery and PV module prices means microgrids for rural power access will reach economic viability sooner rather than later. In the meantime, he said, companies like his might have to be prepared to invest in scaling the technology to meet tomorrow’s demand rather than making projects capable of delivering big returns today.
