The Ryse Energy G-11 wind turbine has achieved MCS certification, the first wind product to do so in more than four years, the Microgeneration Certification Scheme announced on 23 January 20251. The certification was issued through the British Board of Agrément, and the G-11 is now the only MCS certified wind product currently on the Scheme1.
The G-11 is a small wind turbine with 6.5m glass fibre blades1. Ryse Energy says it has been in operation for around 30 years, typically used in agriculture, and is now being integrated into commercial and community energy projects, with features including low noise output, remote data-logging and control, and safety measures1. The company said the product was MCS certified in the past, and that the process faced difficulties in the intervening years1.
Richard Caldow, Managing Director and CEO Europe and Americas at Ryse Energy, said certification matters to the company because it matters to its clients1:
"It assures them of the quality, reliability, and performance of our G-11 product, and opens up opportunities like the Smart Export Guarantee (SEG), which allows our clients to earn money by exporting excess energy back to the grid."
On the certification process, Caldow said finding a product Certification Body that assessed against the Small Wind Turbine Standard (MCS 006) was one of the key challenges, as many Certification Bodies did not renew their accreditation when the Feed-in Tariff scheme ended in 20191. The BBA had maintained its accreditation and supported Ryse through the process1.
Caldow said demand for the G-11 is growing as more customers prioritise energy security, and that many consumers are replacing aging or faulty turbines with the G-111. For those benefiting from a feed-in tariff, he said using a certified replacement turbine ensures they can retain those benefits1. He also said more than half of the company's new enquiries are from customers looking to combine wind with their solar PV system to provide year-round energy security1.
Why it matters for households
MCS certification is the route by which a small wind installation can be registered for support schemes, and the announcement ties the G-11's listing directly to eligibility for the Smart Export Guarantee, under which exported electricity can be paid for1. For a household already receiving Feed-in Tariff payments, the certification of a replacement turbine is presented as a way to keep those benefits when an older machine is swapped out1. The wider context is thin: the announcement says no other wind product is currently certified on the Scheme, so households considering wind have a single listed option at present1. The MCS certification route for wind and hydro installations and the scheme's own rules set out how products and installers are listed, and certified products appear in the MCS certified product directory. The Feed-in Tariff itself is closed to new applicants, as set out in the guide to the closed scheme.
What happens next
Ryse Energy said it is expanding its product range beyond small-scale wind into battery storage and solar PV, and will launch a new training zone in the UK focused on small-scale wind turbines1. No dates were given for either1. The announcement also refers to MCS lobbying on permitted development for distributed wind, without setting out a timetable1.
