A wind turbine will be generating power for Lynn’s Queen Elizabeth Hospital from spring next year.
Green energy company Ecotricity is nearly finished the civil construction stage with the concrete foundation to be poured in November.
The concrete will then be left to cure over the Christmas period before the turbine is delivered and put up over two weeks from mid-January.
Once completed it is expected to generate around 1.5 million units (kWhs) of green electricity a year.
Much of the electricity will be used by the hospital which will purchase it at a 20 per cent discount.
In addition to saving on its energy bills, the trust will also benefit from a reduced carbon footprint, saving over 600 tonnes of CO2 per annum.
A community benefit fund, which offers £1,000 a year, will be offered to groups once the turbine is working.
Dorothy Hosein, hospital chief-executive, said: “This is just part of our energy strategy which seeks to make QEH as cost effective as possible when it comes to our energy needs.
“We have also invested in a combined heat and power plant which was completed on time and under budget and we are making our wards as energy efficient as possible as part of our ward refurbishment programme.”
