On 8 April 2014, the European Commission granted a subsidy to the Solar Highways project. Following market consultation for the further development and construction of the barrier and a decision on the location, the project was tendered in October 2017. Construction began in June 2018. The barrier has been operational since December 2018. It will be monitored as a demonstration project until 2020. After this, Solar Highways will continue to supply green electricity.
