+
+Write the given IESopt model to a file with the specified filename and format.
+
+Be aware, that this function will overwrite any existing file with the same name!
+
+# Arguments
+- `model::JuMP.Model`: The IESopt model to be written to a file.
+- `filename::String`: The name of the file to which the model should be written. Note that if the format is set to
+  `FORMAT_AUTOMATIC`, the the file extension will be forced to lower case to allow detection.
+- `format::JuMP.MOI.FileFormats.FileFormat` (optional): The format in which the model should be written. The default is
+  `JuMP.MOI.FileFormats.FORMAT_AUTOMATIC`; if left as that, it will try to automatically determine the format based on
+  the file extension.
+
+All additional keyword arguments are passed to the `JuMP.write_to_file` function.
+
+# Returns
+- `String`: The absolute path to the file to which the model was written.
+
+# Example
+```julia
+import IESopt
+
+model = IESopt.generate!("config.iesopt.yaml")
+IESopt.write_to_file(model, "model.lp")
