EP-SIM is an online platform that provides users with access to an electric market simulation engines via the web. This type of service allows users to run simulations and analyze the electricity market behavior without the need for specialized software installation or purchasing different licenses for optimization and visualization licenses.

EP-SIM web services typically provide a user-friendly interface that allows users to input parameters and constraints for the simulation, such as electricity demand and available generation capacity. The service then uses mathematical algorithms, optimization methods, and machine-learning approaches to simulate the operation of the market and generates results and analysis for the user. The outputs include but not limited to, generation breakdown for different technologies, annual capacity factors, market clearing price, and etc. EP-SIM services are investigating the current status of electricity markets and the outlook for electricity markets by proliferation of renewables.

EP-SIM web service is particularly useful for energy sector organizations and electricity market role-players who may not have access to specialized software or the resources to run complex simulations on their own. Here, electric market and network simulation web services are a convenient and cost-effective way to access electric market simulation tools and to gain insights into the behavior of electric power markets.
