The 2.5 MW installation (pictured) is to power utility Dwr Cymru Welsh Water’s Five Fords wastewater treatment plant in Wrexham with almost 10,000 photovoltaic panels.
Developer Dulas said the project used four Fronius Aglio 460 central inverters, a first in Europe. The system is expected to generate 1830 MWh per year and save 1084 tonnes of CO2.
The firm added that the solar system, installed on unused land, is aimed at helping the utility meet its carbon reduction target of at least 50% by 2032.
Mike Pedley, head of energy at Dwr Cymru Welsh Water, said: ‘It’s no secret that traditional water treatment works are energy intensive operations that provide critical services to local communities 24 hours a day, seven days a week.
‘So at Five Fords,’ he continued, ‘we are creating an innovative energy park that will maximise the sustainability of the plant.’
