    This paper describes an innovative approach of cooptimizing the energy and ancillary raise and lower services markets in the Australian National Electricity Market. A heuristic based technique called Horizon Scan [1], [2] is applied as the optimization procedure to find optimal solution for the problem. Horizon Scan is a heuristic based technique to search for optimal solution in a non-linear solution space. The paper is an extension to work that has been originally presented [3] and [7]. It includes a case study depicting simplified two region market model. Optimal schedules resulting in economical dispatch costs are obtained when Horizon Scan is applied to optimize trading between multi-regions with inter-connectors. Linear and non- linear constraint equations are also included in the model to take into account dynamics of the power system.
