The Global Community for Sustainable Energy Professionals
Since 2006 I started my own company: Econ International BV
We perform:
- consultancy service,
- Interim project management
- Interim account management
All on electrical equipment or systems (production, transmission and distribution systems and railways)
We are specialised on:
- Power- and generator transformers (specification, design review, inspection, failure analysis)
- Power Quality and reliability of electrical grids
- Energy efficiency and renewables
Often windturbines in the range between 300 kVA up to 3000 kVA are connected to the MV grid by a distribution transfo
This introductory webinar explains how a small-scale wind energy system works, what is the most suitable solution in your case and, if it makes sense, how to start planning and building your installation.
After a briefing presentation, a case study was presented using the RETScreen analysis software.

In countries that started early with wind energy (Germany and Denmark), old wind turbines are often placed at locations where the wind is very good. Since the best locations for wind in these countries are occupied by old wind turbines with lower energy outputs compared with new wind turbines, programmes were started to replace the old turbines (5 up to 15 years old) with modern ones. With repowering, first-generation wind turbines can be replaced with modern multi-megawatt wind turbines.
The first-generation wind turbines can then be used in developing countries. Growing energy demand in developing countries stimulates the use of renewable energy sources, such as wind power, to provide a sustainable and environmentally-friendly power supply. For most of these countries, projects with new wind turbines have proven to be unaffordable: that is why using these lower-cost turbines may be an option.
This webinar summarises results of repowering programmes and used wind turbine projects.
In countries like Germany, Denmark, or the Netherlands, wind power is already so widespread that few onshore sites ar
