Challenges to overcome
Until 2014, micro hydro plants were not allowed to feed into the grid.
New legislation has changed this, but micro hydro plants still face scepticism from local grid owners who are concerned about providing fair and equal access. This is one challenge. Another is that in a small remote plant such as Skie, the instal-lation consists of equipment from several different suppliers. Each element needs to withstand the tough local conditions, and to work smoothly in combination with the others.
The benefits of small scale hydroelectric plants
Renewable energy source with low environmental impact
Easily available and delivers power to remote areas
Makes use of natural energy potential in rivers
Reasonable investment level
Can harvest the power of micro water or small streams and feed back any excess electricity to the grid
About Micro hydro
Micro hydro systems use the natural flow of the water to produce up to 100 kW of electricity. They eliminate the need for fuel and thus provide an economical energy source for all kinds of power needs, including developing nations. Such systems are also often used to provide energy to small communities or isolated homes, and can even be connected to the grid.
Why was CG Drives chosen?
How did CG Drives & Automation become the preferred supplier for the new Norwegian plant? The main reason behind the owners’ decision was the robustness and reliabilty of our products.
Emotron AFE* drives, 90kW were installed in the new Skie plant. Based on standard Emotron AC drives, they offer the same reliability, easy handling and advanced functionality as the standard model. They are delivered as complete solutions in IP54 classified cabinets.

Plans for future plants?
“Since the micro hydro installation in Skie has been working well since its installation two months ago, three similar plants are now being planned for Drammen in Q3/Q4 2014,” says Johannes Fossheim, one of the owners.
