Research on Electro - Thermal Energy Storage

Electro-thermal energy storage (ETES) systems convert electricity into heat and store it until used. Electric storage water heaters are the most common example of an ETES system.

New ETES technologies have been developed and some of these could potentially supply a wide range of heat requirements, for example industrial steam or high temperature air, and internationally interest is growing in the role that ETES may have in enabling electricity to be an affordable source of process heat for businesses in place of, or alongside, other heat options. Other potential ETES benefits include enabling more efficient use of electricity networks or greater use of intermittent renewable electricity generation.

We are seeking to procure research from qualified and experienced research providers. The research will produce evidence to help EECA understand and quantify the potential ETES opportunity for New Zealand’s businesses and energy systems. This evidence will inform possible future research, modelling and programme design.

EECA will be holding a supplier briefing to provide an opportunity for supplier to ask questions relating to the requirements of the tender. A link to register for the supplier briefing will be published by addenda when it is available.
