Energy projects in Wales

By harnessing the power of nature and being careful with the energy we use, the places we find special can be beautiful forever. Here are just some of the projects we've been working on.

The water-wheel at Aberdulais Falls viewed at ground level

Re-inventing the water wheel 

With a history dating back 500 years, this renovated waterwheel is now generating renewable electricity and helping us achieve our green energy goals by 2020.

Modern means to fuel a medieval fortress  

The 700-year-old fortress is leading the way in 21st century green energy, with a £23,500 roof-mounted solar thermal system which supplies hot water to the castle during the summer months.

Cacti in the glasshouse at Dyffryn Gardens

Exotic plants bask in biomass warmth 

A biomass boiler is now heating the exotic glasshouse, producing the perfect environment for orchids, cacti and vines to flourish. A ground source heat pump and solar panels are also pruning the garden's fuel costs.

The hydro intake weir at Hafod y Llan farm, Snowdonia

Turning water into a conservation win 

Sensitively crafted into the rugged Snowdonia landscape, this hydroelectric scheme is now producing power sold through our green electricity partner Good Energy, which goes towards conservation work in Wales.

Drop of sunshine in every cup of tea  

Solar panels now generate enough electricity to power the tearoom at the famous garden and two electric vehicle charging points in the overflow car park. They even recharge gardeners' battery powered tools.

Marine source heat pump at Plas Newydd, Anglesey, Wales

A mansion powered by the sea 

We’ve built the UK’s largest marine source heat pump here on the North Wales coast so that we can use the sea to warm up this Welsh mansion. It's part of our ongoing programme to use more renewable energy.

Castle's new boiler is environment friendly 

Around 100 rooms in this Victorian gothic castle are now being heated by a biomass boiler, which produces humidity levels much better for the preservation of artwork and furnishings.

Horticulture just got greener 

Utilising a ground source heat pump, solar system and a reed bed to treat compost, this prestigious garden nursery is self-sufficient and now generating more energy than it uses.
