Norvento will deliver the first units in the fourth quarter of 2014 and the remaining turbines in early 2015.
VG Energy will service and maintain the turbines after installation. The company becomes the first nED operations and maintenance subcontractor to cover the northern UK.
VG Energy said it will also unveil nED100 as a key part of its product portfolio as part of the Scottish Agency Agreement.
Norvento business development director Ivo Arnús said: "In a market where single and twin-turbine installations are the norm, this seven-turbine deal and Agency agreement with VG is a clear sign that firms are starting to recognise and buy in wholeheartedly to the unique advantages of nED100.
"VG will not only roll out nED100 as a key part of its own development pipeline, but also promote, operate and maintain the turbine throughout Scotland. This agreement signals the start of a close partnership between the two firms."
VG Energy director Gordon Smith said: "As VG builds out a portfolio of turnkey sites and continues to promote farm-scale renewables across Scotland, it was important to make an informed decision when it came to choosing a turbine and manufacturer.
"Based on current market conditions, Norvento’s nED100 stood out as the clear frontrunner in terms of impacts and reliability. It’s one of the quietest machines on the market and incorporates a range of remote sensors that will really augment our capacity for swift, efficient O&M support in the coming years."
Prior to the latest agreement, Norvento and VG Energy have earlier worked together on a twin-turbine site in Castle Douglas, which was commissioned in August 2014.
