Construction has started on Cornwall’s first, smart grid-connected wind turbine which will power the equivalent of around 1,100 homes and help cut carbon emissions.
The 2.3 megawatt (MW) turbine will be sited on Cornwall Council land at Ventonteague, near Carland Cross, on the A30, and is the first to be built in Cornwall since 2016.
It will generate enough renewable electricity to reduce Cornwall’s greenhouse gas emissions by more than 2,800 tonnes a year over the next two decades.
The smart grid-connected turbine will help Cornwall better manage its energy supply and power the equivalent of around 1,180 Cornish homes, representing a significant contribution towards the Council’s climate emergency agenda.
Transforming the energy sector is an essential part of Cornwall Council’s response to tackling the climate emergency as Cornwall now generates around 37% of electricity from renewables, up from around 6% in 2009.
Award-winning initiatives such as the Green Cornwall programme have driven forward major changes promoting community and Council-owned renewable energy projects and developing potential new forms of power in technologies such as deep geothermal.
The new wind turbine is part of an EU-funded trial and forms part of the innovative Cornwall Local Energy Market (LEM) which aims to help increase the amount of renewable energy that can be deployed by managing the electricity network more efficiently.
Launched in December 2016, the LEM project is receiving £11.5m support from the European Regional Development Fund (ERDF) and is a collaboration between Centrica, Western Power Distribution (WPD), N-SIDE, Imperial College, the University of Exeter and National Grid.
The project brings Cornish homes and businesses together via a fully automated online flexible energy market platform.
The platform allows network operators, the organisations that run our electricity distribution and transmission networks, to improve the way the grid works by buying energy flexibility from local homes and businesses, helping to balance both grid demand and capacity. The LEM is now in its live trials phase, which are set to continue until March.
Cornwall Council will own and operate the turbine, once constructed, with Centrica responsible for constructing and commissioning the infrastructure that will connect the turbine to the grid and the LEM.
Construction work is currently underway with the turbine expected to be operational this summer.
The site is less than half a mile from the existing 20MW Carland Cross wind farm.
The LEM is also about to install one of Cornwall’s largest battery storage units on premises owned by Wave Hub Limited in Hayle.
The 1MW battery will provide energy resilience to the Wave Hub site and the local grid.
Wave Hub Limited, which is solely owned by Cornwall Council, will own the battery storage system once in place, with Centrica responsible for the funding, construction and operation. Commissioning is due next month.
Wave Hub Limited exists to help wave energy technologies and offshore wind developers from around the world test in open sea conditions and provides some of the best conditions in Europe.
Cornwall Council has a track record in championing clean energy through the nationally renowned Green Cornwall Programme which has delivered energy efficiency improvements in over 3,000 homes, the UK’s first collective energy saving in excess of £500,000 for Cornish residents and England’s first community energy revolving loan fund.
It is a key investor in two, pioneering geothermal heat and power projects at the Eden Project and at United Downs near Redruth and it was also the first local authority to develop its own solar farm.
