Installing new energy infrastructure on the Isles of Scilly, UK, is a tricky proposition, given the islands’ location 28 miles off the Cornish coast, and a population of just 2,500 to share the high costs.

But an exciting new project is about to transform the islands’ energy provision, reducing energy costs and supporting clean growth, through the use of a smart energy grid.
By 2025, the Smart Islands programme aims to provide the Isles of Scilly with 40% of its electricity from renewables, cut Scillonians’ electricity bills by 40%, and revolutionise transport, with 40% of cars to be electric or low-carbon. The key to this will be an integrated smart energy system, operated by a local community energy services company and monitored through an Internet of Things platform.
In the UK Government’s Industrial Strategy, published in November 2017, it was announced that the Local Growth Fund would provide £2.95m funding to the project, via the Cornwall and Isles of Scilly Local Enterprise Partnership.
The project will be led by Hitachi Europe Ltd in a public-private partnership, along with UK-based smart energy technology company Moixa, and smart energy software company PassivSystems.
Colin Calder, CEO of PassivSystems, explained, ‘Our scalable cloud-based energy management platform will be integrated with a range of domestic and commercial renewable technologies, allowing islanders to reduce their reliance on imported fossil fuels, increase energy independence and lower their carbon footprint.
‘These technologies have the potential to significantly increase savings from solar PV systems.’
Aiming to increase the renewable capacity installed on the island by 450kW and reduce greenhouse gas emissions by 897 tonnes CO2 equivalent per annum, 100 homes on the islands (a tenth of the total) will be fitted with rooftop solar photovoltaic systems, and two 50kW solar gardens will also be built.
100 homes will also get energy management systems, and 10 of them will pilot a variety of additional smart energy technologies such as smart batteries and air source heat pumps.
Chris Wright, Moixa Chief Technology Officer, said: ‘Ordinary people will play a key role in our future energy system. Home batteries and electric vehicles controlled by smart software will help create a reliable, cost-effective, low-carbon energy system that will deliver savings to homeowners and the community.
‘Our systems will support the reduction of fuel poverty on the Scilly Isles and support their path to full energy independence. They will be scalable and flexible so they can be replicated easily to allow communities all over the world to cut carbon and benefit from the smart power revolution.’
The burgeoning smart energy industry is attracting serious investment – only this week, the Department for Business, Energy and Industrial Strategy (BEIS) announced it will invest up to £8.8 million in new ideas for products and services that use smart meter data to reduce energy demand in small, non-domestic buildings; while Manchester-based smart energy start-up Upside Energy this week announced it had secured £5.5m in its first round of venture capital financing to commercialise and deploy its cloud-based smart grid platform.
Smart energy covers a range of technologies intended to allow both companies and households to increase their energy efficiency. Smart meters are currently being offered by energy suppliers, with the aim of allowing energy companies to automatically manage consumer energy use to reduce bills, for example, running your washing machine when energy demand (and therefore cost) is low.
Battery technology also plays a major role in smart energy, allowing users to store renewable power and potentially even sell back into the grid as demand requires. In the Industrial Strategy, the government announced a new £80m National Battery Manufacturing Development Facility (NBMD) in Coventry, which will bring together academics and businesses to work on new forms and designs of batteries, as well as their chemistry and components.

The funding for this and a further £40m investment into 27 individual battery research projects have been allocated from the £246m Faraday Challenge, which was announced in July.
The Smart Islands project promises a real-world demonstration of how a community can harness the power of the Internet of Things to maintain an efficient, inexpensive, and clean energy system.
