For the Public Utilities Office (PUO) of Western Australia, Brattle experts provided advice on the design and implementation of a competitive capacity market construct. Our experts reviewed the overall design proposed by the PUO and evaluated options for the design of auction parameters such as the demand curve. Brattle recommended approaches to developing robust supplier-side and buyer-side market power mitigation constructs. Our experts also provided recommendations on the design of administrative processes needed to conduct the auction and the governance of such processes.
