The integration of zero and low carbon energy technologies, such as solar panels and heat pumps, into a smart grid had a boost today with the trial of a new electricity storage system.
Three electricity storage units, manufactured by S&C Electric, have been installed as part of a “zero carbon homes” project in Slough.
The 10 zero carbon homes, developed by energy giant SSE and funded by Ofgem’s multi- million pound Low Carbon Network’s Fund, already contain a range of green technologies, including solar photovoltaic panels, water recycling systems, and enhanced insulation.
However, until now electricity produced by the solar panels could only be used when the sun is shining, leaving the homes reliant on power from the grid.
The new lithium batteries aim to ensure the power generated by the solar panels can flow as and when needed, with the technology integrating with the grid via S&C’s Pure Wave Community Energy Storage System.
The pilot aims to find out if it is cheaper to install energy storage technology, than to replace transmission cables, with the project proving the first to be funded by the LCN that places batteries close to customers’ homes, rather than at the point of use or at a substation.
According to the Institution of Engineering and Technology, the lifetime costs of installing and maintaining underground cables varies from £10.2m to £24.1m per kilometre. Digging up roads to replace cables can also cause significant disruptions to local businesses and communities.
The project also aims to find out if energy storage can be used for voltage support – by allowing greater flexibility in the grid as greater amounts of intermittent renewables come online.
If you are interested in grid connected or off grid Energy Storage, zlc energy are on hand to help. We’ve just completed another major installation which will enable an eco-mansion to function off grid during power cuts and to optimise use of on site renewable energy generation.
