About City-OG
Gas Energy Services

With over 100 years of history and experience each, City Energy and Osaka Gas formed a business venture, City-OG Gas Energy services Pte Ltd in 2013.

City Energy is the only producer and retailer of piped town gas in Singapore, as well as a retailer of natural gas, while Osaka Gas is the second biggest natural gas provider in Japan and is a diversified energy company.
With City Energy’s strong business base in Singapore, and Osaka Gas’ wide experience in energy solutions, a business venture was formed.

From business know-how to technical knowledge that both companies had injected into City-OG, the company pride itself as an energy solution provider as well as an established gas retailer with customers in various industries.

Over the years, City-OG has helped their customers to optimise their energy efficiency, adopt industry best practices, improve productivity, and lower operating cost.
