We assist market participants and policymakers with important market design questions in all of the major electricity markets across Europe, Australia, and North America. Brattle has run detailed simulations of electricity markets to quantify the impacts of changes in market rules and market structure. In Western Australia, we have advised in connection with the redesign of the capacity market construct to reduce the costs to consumers of excess surplus capacity, while continuing to meet reliability standards. In the National Electricity Market we have advised on topics including transmission network pricing, active participation of demand-side resources in the wholesale market, and the impacts of environmental policies on the electricity market.
