Aeolus helps RETScreen update its cost database for onshore and offshore wind

Published March 4, 2018

RETScreen is a Clean Energy Management Software for energy efficiency, renewable energy and cogeneration project feasibility analysis as well as ongoing energy performance analysis. It is developed and maintained by the Government of Canada through Natural Resources Canada’s CanmetENERGY research centre in Varennes, Quebec. The software is supported by an international network of experts from industry, government and academia. Principal partners include the National Aeronautics and Space Administration (NASA), the Renewable Energy and Energy Efficiency Partnership (REEEP), the Independent Electricity System Operator (IESO), the United Nations Environment Programme (UNEP) and the Global Environment Facility (GEF).

Aeolus was contracted by Natural Resources Canada to provide critical input on latest trends in onshore and offshore wind costs, both in terms of capital and operational expenditure, which are used for updating the RETScreen Expert Software.

RETScreen empowers professionals and decision-makers to rapidly identify, assess and optimize the technical and financial viability of potential clean energy projects. This decision intelligence software platform also allows managers to easily measure and verify the actual performance of their facilities and helps find additional energy savings/production opportunities.

The first version of RETScreen was released on April 30, 1998. As of February 2018, the RETScreen software had more than 575,000 users in every country and territory of the world. An independent impact study estimated that by 2013, the use of the RETScreen software had been responsible, worldwide, for over USD 8 billion in user transaction cost savings, 20 million tonnes per year of greenhouse gas emissions reductions, and has enabled at least 24 GW of installed clean energy capacity.
