Singapore takes big solar step
In June, industrial giant 3M unveiled one of the biggest rooftop solar farms in Singapore atop its Tuas manufacturing plant, representing not only a sprawling new power source for the global science company, but also a banner project that the government hopes would embolden other firms to follow suit.
“This initiative to utilise rooftop space which would otherwise have been unused to generate cleaner forms of energy to power its manufacturing facility is an example of how companies can maximise resources,” said Amy Khor, senior minister of state for the Environment and Water Resources.
The 14,000 square metre solar farm can generate an average of 2.4 GWH of electricity annually through its 6,605 solar panels and 55 inverters. The facility sits atop 3M’s major manufacturing plant in Tuas and can power over 500 four-bedroom flats.
The solar farm is projected to lower carbon dioxide emissions by 1,139 metric tonnes a year, in line with 3M’s efforts to boost renewable energy use to 25% of its total electricity use by 2025.
Under the Sustainable Singapore Blueprint, the city-state is targeting to boost solar penetration rates and solar power adoption in the country’s energy system to 350 MWP by 2020, or about 5% of total projected peak electricity demand.“the switch to cleaner forms of energy will make our economy greener and grow our green economy at the same time. I am glad that companies in Singapore like 3M are adopting solar energy and contributing towards greater resource efficiency and a greener economy,” Khor said.
Earlier in April, European solar photovoltaic panel maker REC
Group also broke ground for its own industrial solar rooftop installation in its factory in Tuas. Projected to go on grid in August, the new solar installation is set to become one of Singapore’s biggest that will feed around 2.6 GWH annually into Singapore’s electricity grid, enough to power 550 HDB fourroom apartments, and will save
1,400 tonnes of carbon emissions every year. “We want to see more companies think and speak carbon,” said Khor, citing the government’s Climate Action Plan which outlines strategies to build a low-carbon and climate-resilient Singapore through improving energy efficiency and investment in solar energy and other low-carbon technologies.
