Currently, the Singapore-based company is available only to business customers, but says it will roll out to residential consumers from Fall 2018, in line with the liberalization of Singapore's retail energy market. The company then plans to expand to Japan and Australia, where there are many power-generating households that Tan said will benefit from the sharing model by selling their excess power to other homes. It's a model that has investors interested, too: Electrify said it raised $30 million in an initial coin offering in March. According to industry analyst Mark Hutchinson, that could be a sign of growing demand for energy disruptors. But, as ever, that will likely mean leaving some traditional players behind.
