**Abstract:** In this article we consider authors' information and computational system for energy facilities' impact assessment on the environment. The necessity of such assessments and development of this system is substantiated. We developed this system as a Web application using the agentservice approach. To develop a database for the system, we utilized ontological engineering of energy and ecology. For assessments, we developed a set of information susbsystems that use approved regulatory methods. Our system can be used for assessment of the impact of both existing and planning energy facilities and also for planning measures to reduce the harmful impact of such facilities. We also performed a set of computational experiments in order to test the developed system. Experiments have shown the correctness of the methods used, and the results of one of them are presented in the article.
