The institute is calling on organizations to participate in this Energy Storage Technology Demonstration program which will see the development, building, commissioning and operation of an energy storage device of sufficient capacity that it can deliver at least 500kW on an 11kV distribution network for approximately four hours.

ETI says that the stored energy will be enough to power around 400 homes for four hours in the winter and will be needed as an important element of the local electricity networks to keep the lights on when renewable generators are not able to operate.

Following the development of the device, it will be tested and commissioned on an operational 11kV distribution site under real conditions for one year to ensure its effectiveness and reliability.

ETI Chief Executive Dr David Clarke said: “The successful development and deployment of reliable, low cost energy storage technologies will play a critical role in the successful delivery of secure and sustainable energy systems in the future.”
