Energy neutral plant nursery at Powis Castle? – new and old

the small 10kw system on the bank above the green houses at Powis

As well as completing the large PV project another objective has been delivered. We set out 18 months ago to turn the plant nursery at Powis castle near Welshpool from £6000 a year electricity guzzler into and energy neutral nursery or the closest thing we could. Previous blogs showed the heat pump and ground collector going in to feed heat to all the greenhouses. Well the other side of the energy circle is now complete which was to produce electricity.  All in – the Nursery has 50kw of PV installed and thanks to nPower a 27kw ground source heat pump. Time will tell and some decent monitoring if the total electricity consumed last year will match the total electricity produced and maximised with the heat pump. The advantage with this site is that the Gardeners have also recorded inside and outside temperature readings and electricity use daily for over 10 years which will give us that rare thing ‘high quality data’ to be able to make a comparison. Everybody concerned is really please with the way the nursery has turned out. The Gardeners at Powis have really driven this project and made it possible.  a) moving from mains water to borehole b) filter bed feeding to cut down on excessive watering c) heat pump d) PV’s
