grid connected storage

Gridstor, a project developed by energy consultancy and testing authority DNV GL to establish industry standards for grid-connected energy storage implementation, could fold due to lack of interest.

Launched in June 2014, the project aims to develop a practice through industry standardisation to drive the safe and secure implementation of grid-connected energy storage systems forward and to accelerate the integration of renewable energy sources into the grid.

Renewable Energy Systems (RES) Canada has received a final certification for starting operation of its 8MW energy storage system (ESS) in Ontario, Canada.

The ESS, named Amphora, consists of two containers with lithium iron phosphate batteries and a container of inverters that converts the DC output to AC for the grid. The batteries have a total range of 8MW and a capacity of 2.6MWh. BYD America supplied the equipment.

French battery supplier Saft is to supply a lithium-ion battery energy storage system (ESS) to a 12MW PV plant on Kauai Island, Hawaii, US.

Saft was contracted by Kauai Island Utility Co-operative (KIUC) to provide the 6MW ESS consisting of 10 containers in order to stabilise the Kauai island grid. Saft said the deal is worth “multi-million dollars”.

Hitachi has announced it has developed an energy storage system for the US market that can be integrated to high-voltage power lines to capture energy that has been generated by renewable sources. The stored energy can be sold back to the grid from the lithium-ion battery at times of high demand.

The Japanese company believes the 1MW system, known as CrystEna, will help to stabilise the grid by supporting solar and wind power.
