“The best days of renewable energy are ahead of us,” said Gary Lam, Co-Founder of FranklinWH. “Battery storage systems are positioned to expand in the energy market because they are strong alternatives to the vulnerable, outdated and expensive energy grid. This funding from Particle Future will help FranklinWH advance home battery technology and make renewable energy options more accessible.”

The company highlighted that the US Department of Energy (DOE) estimates that two-thirds of the country has been at risk of a power outage this summer, and that this combined with an increasingly complex energy landscape and federal incentives are paving the way for the ‘age of the battery’.

FranklinWH’s Franklin Home Power solution comprises a residential battery, a power control system and an app allowing for smart energy management.

“Solar panels had their day in the sun over the past few years, but homeowners are becoming interested in pairing solar with other energy efficient technologies to balance a home’s energy supply,” said Vincent Ambrose, Chief Commercial Officer at FranklinWH.

The company highlighting Puerto Rico as an addressable market likely stems from policies after Hurricane Maria in 2017 which are seeking to increase the amount of distributed energy resources (DERs) and virtual power plants (VPPs) into which those DERs can be aggregated, to shore up the grid’s resilience.

There was good news for the home battery and VPP space this week in the mainland US too, with VPPs or incentives programmes using home batteries launched or extended in Texas, California and Vermont.
