# ESDL models and tools During the last two years different software applications have been developped based on ESDL: * [MapEditor](/esdl/esdl-based-tools/mapeditor.md): Map based energy system scenario editor * [ESSIM](/esdl/esdl-based-tools/essim.md): Energy System Simulator * [EDR](/esdl/esdl-based-tools/energy-data-repository.md): Energy Data Repository * ESSIM financial: Gives insight in the effects of investments in the energy system of one or more stakeholders on the cashflows between all stakeholders in this system * ESDL based loadflow calculation of electricity grids --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://energytransition.gitbook.io/esdl/esdl-based-tools.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
