Plans are in place for a combined 160MW solar and wind project with up to 40MWh of energy storage in the Indian state of Andhra Pradesh, while a smaller scale demonstration project experimenting with multiple technologies is being developed for Kerala.

Major Japanese business and government entities have extended their involvement in energy storage with the announcement of the country’s first virtual power plants, an investment in a US frequency regulation project and partnerships on technology.

Nuclear generation company Exelon and chemical company Albemarle, which has lithium mining facilities, are investigating opportunities in the energy storage space, having partnered with battery energy storage investor Volta Energy Technologies to do so.

Powerhive has been delivering access to electricity for rural and remote communities since its inception in 2011, classifying itself as much as a technology company as it is a developer or vendor of energy solutions.
