A host of Northern Ireland Housing Executive tenants and customers in Coleraine have made major savings on their electricity bills thanks to a new innovative project.

The Girona Project, a renewable energy scheme, saw 13 Housing Executive properties fitted with solar panels and storage batteries in 2021.

The first year of the scheme, which was supported by government research agency Innovate UK, showed that on average those taking part saved 55% on their electric bills over a 12 month period.

There are 60 participants from Coleraine in the scheme including private residents, businesses and charities as well as social housing.

Housing Executive tenant John McCloskey, from Ballysally, said: "I am making good savings using this pioneering technology. It was installed almost two years ago. In good weather I have seen my household electricity bills cut from £45 to £11 in a month. Last August it was £12 and in September, £18, which is hard to beat.

"Even though the cost of energy has risen in recent months, I am still benefiting. In January my bill was £65 and in February it was £52. This covers cooking, heating and the shower and my home is nice and warm. 

"You can even download an app on your phone which shows you how much energy is being produced and what you save."

Eddie McGoldrick, founder of The Electric Storage Company, which designed the project, added: "This system combines renewables, electricity storage and smart grid technology to deliver cleaner and lower-cost energy to business and domestic consumers. 

"Project Girona enables users to generate and store their own renewable energy, generating a significant saving on their standard electricity bills.

"Girona demonstrates the important role that battery storage can have in making the most of affordable renewable energy from solar PV installed in social housing.

"Tenants can use electricity generated and stored during the day at the time that they need it. This reduces their energy bills and their risk of fuel poverty. 

"In addition, the electricity generated is carbon free which reduces the tenants' carbon footprint. In the first year the project saved 40 tonnes (40,000 kg) of carbon dioxide – that is the equivalent to the emissions of 19 family cars.

"Girona also generated 171MWh and exported 31MWh of green electricity over 12 months."
