Orkney is a net exporter of electricity- but renewable generation is at
times limited by the export capacity of the subsea cables to the Scottish
mainland and between the islands.
As a response to these limitations, Orkney has innovated. In 2009, the
Islands became home to the UK’s first ‘smart grid,’ which uses a new Active
Network Management approach to make better use of the existing network by
instructing generators to control their output.
Now, with help from Heriot-Watt University, Solo Energy – a new
100%-renewable energy supplier business operating in Orkney – is pushing
ahead with the installation of large numbers of actively managed
distributed energy storage assets in homes and businesses.
Orkney has the highest proportion of households generating their own
electricity of anywhere in the UK. Orcadians generate more than 100% of
their total electricity needs from renewable sources and have pioneered the
utilisation of renewables whether that be wind, wave and tidal and now they
are looking at energy storage.
Solo Energy – whose directors include mother-and-son Maureen and Simon Di
Pietro from Ireland’s DP Energy – plans to create a demand-side energy
storage network on Orkney, utilising battery storage technology in order to
shift customers’ energy supply from periods of peak demand and peak
wholesale energy price, to periods of peak renewable generation and low
demand / low wholesale energy price.
Solo Energy has teamed up with Colin Bullen – who is based at Heriot Watt
University’s International Centre for Island Technology – and with local
housing developer Orkney Builders.
Mark Hamilton, Chief Executive, Solo Energy, said: “The key to fully
eliminating fossil fuels from the grid infrastructure is energy storage.
“The work with Heriot-Watt on this project will give us critical technical
input to the design of the distributed storage network as well as providing
firm evidence of the commercial and technical case for distributed energy
storage in terms of cost savings for residents and broader benefits to
local renewable generators and the electricity grid.”
Previously, Hamilton led the technical and commercial development of the
world’s largest tidal turbine at Scotrenewables Tidal Power, initially as
chief technical officer and later as managing director.
