Queensland calls for multiple four hour batteries to deal with solar duck curve.

Queensland calls for multiple four hour batteries to deal with solar duck curve.
Energy Queensland – the state owned network operator – has announced a tender for multiple battery storage installations for up to four hours of storage to support the roll out of renewables, and solar in particular.
The tender is seeking “megawatt scale” battery storage installations of around 4MW and between two and four hours of storage, and is focused on the distributed, or local, networks, and will support the rollout of both large scale renewable and rooftop solar installations.

Queensland is currently the leading state for solar in the country – both in terms of large scale and rooftop installations – but it has little in the way of storage, apart from the Wivenhoe pumped hydro facility in the south of the state, and it often experiences negative prices in the middle of the day which could discourage future investment.
