(eco)Village within a Village

The Welsh Government is embracing low-impact housing with the unveiling of its first village within a village – the Pentre Solar “eco hamlet” within the traditional, stone-walled village of Glanrhyd in Pembrokeshire. The six timber homes have solar panels capable of producing 6000 kilowatt hour per year, low energy use and a A++ energy rating.

Following the successful construction of a prototype house built by start-up Western Solar in 2013, the Welsh Government gave the company £141,000 to help create its nearby production base for the homes, which will house tenants from Pembrokeshire council’s social housing waiting list. With low energy use and access to a shared electric car, Western Solar said residents could avoid up to £2,000 a year on energy costs and consumption.

The eco hamlet was built with insulation material made from recycled paper and local Douglas and Fir wood sourced from the Gwaun Valley. Local people were hired and trained to build the homes, which cost about £100,000 each to build – comparable to a conventional build, according to Western Solar.

About 40% of the fabric of the houses is made in the factory, significantly reducing the build time; it takes only a week to make each house, and less than that to erect it. The company plans to build 1,000 homes over the next 10 years, with the help of partnerships including housing providers and investors.

Welsh Environment Secretary Lesley Griffiths said she was “delighted” to officially open the innovative housing development.
“[It is] not only providing much-needed housing for local people, it is also addressing many other issues such as energy efficiency, fuel poverty, skills development and the use of Welsh timber,” Lesley said.

Low-impact development is recognised by the Welsh Planning system as playing a key role in the transition towards a low-carbon society. Since the ‘One Development Policy’ legislation was introduced in Wales in 2010, it has been possible to build new homes in the open countryside as long as there is a clear commitment for to sustainable living, natural building techniques, and land-based livelihood.…

Free Home Batteries Trial Increases Grid Capacity

A small community in South Yorkshire, UK has been targeted for a trial involving solar power and smart batteries. Forty homes in near Barnsley are having smart batteries installed at the end of January. Moixa, Northern Powergrid and Energise Barnsley are all collaborating on the £250 million ($308 million) project.

Moixa Batteries USB port

The Moixa batteries are smaller than a boiler (50cm x 30cm x 20cm), wall mounted with a 20 year lifespan. They even have a USB port so phones and other devices can be charged direct from the battery. Normally costing above £2,500 ($3,000), the residents received their batteries free of charge, with distributor Northern Electric footing the bill. 30 of the homes had solar panels, allowing them to be further independent of the grid. The batteries have good saving potential, giving the residents another reason to be positive about the trial.

The batteries allow residents to use the excess energy their solar panels generate during the day, at night time. They store the energy produced instead of transmitting it to the grid. This will relieve pressure put on the electricity network during times of high output but low demand. It is this reason that prevented the energy company Energise Barnsley placing more homes with solar onto the trial. Without expensive upgrades it is infrastructure which is limiting the number of homes that can have solar power. A project in Carmarthenshire, Wales, faced a similar problem, with only 37% of homes being able to connect with solar energy.

Lower Carbon

As outlined in Moixa’s press release, CEO Simon Daniel stated, “Batteries will allow the electricity system to support much higher levels of low carbon renewable power and increase UK energy independence.”

Linking the batteries in a virtual power plant system allows Moixa to make the wider grid more efficient, causing less need for back up from non-renewable sources. If rolled out across the country, millions could be saved by reducing the peak solar output onto the electricity network.

If the trial is successful, batteries could hold the key to UK energy independence.…
