Fair Isle, one of the UK’s most remote inhabited islands, will soon have 24/7 supply of electricity

Fair Isle, is a three mile long, island in northern Scotland, belonging to the Shetland island group. It is located 24 miles south of the Shetland mainland, between Orkney and Shetland.

Since 1980, the community of Fair Isle, currently totalling 55, has been reliant on a combination of diesel generators and wind power for its electricity needs. However, none of the two, has proved to be sufficient to provide the required amount of energy. One of the two turbines has stopped working, while the other one is reaching the end of its days.

In addition, the back-up diesel generator frequently is turned off during the night, in order to preserve fuel stocks, as deliveries are reliant on the ferry running. Thus, currently, if the wind is not blowing at Fair Isle, the lights need to be off between 11pm and 7am. Furthermore, at present there is no storage ability or capacity for new residents.  Fair Isle is yet another example of the challenges faced by peripheral, isolated, island communities. The community has acknowledged the significance of developing an infrastructure, to allow them to sustain and grow its population, as well as, to transform life on the island.

In the beginning of this year, the project was awarded over £1m of capital stage support by the Low Carbon Infrastructure Transition Programme’s (LCITP) funding call for large scale transformational low carbon infrastructure demonstrator projects. LCITP is supported through the European Regional Development Fund and is a partnership programme led by the Scottish Government, with support from HIE, Scottish Enterprise, Scottish Futures Trust and Resource Efficient Scotland. The Scottish government has promised half the cost of the project (£1.325m), with Scottish Water and HIE Shetland pledges to match fund the project. The Big Lottery Fund has been approached for £600,000 (not yet confirmed),  the National Trust may contribute up to £100,000 and Fair Isle Electricity Company will put in £20,000. The Shetland Islands Council (SIC) political leader Gary Robinson said:

“It is clear that no stone has been left unturned in this one in search of funding. What we have here is a well thought through and carefully worked up proposal. It’s absolutely clear that Fair Isle needs to have a reliable energy scheme. I am really pleased to see the lengths gone to bring in external funding”.

The £250,000 funding granted by the Highlands and Islands Enterprise (HIE), marks the completion of the full funding package totalling at £2.6m. Fiona Stirling, development manager at HIE’s Shetland area team, said: “It’s a key factor in attracting new people to the island as well as helping businesses to develop.”

Great Glen Consulting was selected to be the project manager assisting and developing the project, while the technical design and engineering of the project will be carried out by Arcus. The project is being led by a community group, known as the Fairs Isle Electricity Company. The company director Robert Mitchell said:

“Having a constant electricity source may help to attract more people to live in Fair Isle as well as benefit the residents. It will also bring new employment opportunities and sustain existing employment. This ambitious project is the first step in ensuring that the community of Fair Isle continues to thrive.”

The £2.65m investment is for three 60kW wind turbines, a 50kW solar array and lead-acid battery storage of 500 kW hours. According to the project manager Maurice Henderson the summary of costs is the following: £620,705 will be spent on the high-voltage system; £609,435 on the storage; £660,000 on the wind turbines; £125,000 on the solar power; £98,000 on new diesel generators; £192,000 on project management and £345,786 on a contingency fund. Mr Henderson acknowledges that the scheme is not of the highest technology quality available, but he asserts that it is intended for robust reliability, which is an essential consideration for a remote island. It is envisioned to make best use of the use of wind in times of low demand. The scheme will also extend a high voltage network to the north of the island to enable grid connections to the Scottish Water treatment works, Fair Isle Bird Observatory, the airstrip and the North Haven harbour.

South Mainland councillor Allison Duncan believes that the project would help secure the future of Fair Isle, as three new families were moving in, after years of population decline. Project manager Maurice Henderson said: “I would consider this as a key project in the development plan for Fair Isle for growing more population.”

Responding to the announcement, Stephanie Clark, Policy Manager at Scottish Renewables, said: “Renewable technologies are bringing power to remote communities which otherwise either wouldn’t have electricity, or would have to rely on diesel generators for their supply. It’s great to see Fair Isle will soon join the likes of Eigg and Gigha in taking advantage of a green electricity network. Scotland’s geography and abundant renewable energy resource make it the perfect place to test these advanced energy system.

Scotlands Gridlocked Islands: A £725 Million Opportunity

ERI 11-03-2016
Burradale wind farm in Shetland, which in 2005 set a world record for wind power in terms of power production per unit of installed capacity.

A new report prepared for the Scottish Government by Baringa consulting group assesses the economic opportunities of renewables for Scotland’s island communities. The main findings are:

Economic benefits of up to £725 million (€939 million) for the island economies over the next 25 years, which includes up to £225 million (€291 million) in community benefits

Local economic stimulus could mean an average boost of 5% to local economic output across the Islands

Community revenue due to project equity could total up to £390 million (€505 million)

Employment boost of up to 2,000 jobs in the peak development phase across the Islands

In GREBE we are looking to help communities and businesses adopt renewable technologies, and islands have been identified as a key geographic area of focus within the project. This report highlights how large the opportunities they present are and how pertinent it is to help provide tools to access these.

However, the impressive figures of the report won’t be realised without external drivers. Improved grid connections have been identified as a vital enabler for Scottish islands to realise their full renewable potential. As it currently stands, of the three island groups examined in the study the Western Isles has a 22 MW connection to the mainland; Orkney has a total mainland connection of 44 MW; and Shetland is not connected. This means the grids on the islands are either at or near saturation point, so more renewable generation is difficult to incorporate into the system. To give an idea of the scale of the grid issue another 2.4 GW of grid capacity by 2030 would be needed for the benefits listed to be realised. In the Orkney Islands alone alleviation of these grid constraints could increase income to existing wind developments by around £2.7 million annually.

It is important to highlight that the benefits of developing renewables in island locations extend beyond those to the businesses involved and local communities. The winds experienced on the islands of Scotland make them some of the best locations for onshore wind in the world. Coupled with the geographic and resource diversity (such as wave and tidal power) offered by the islands this can help reduce overall renewable variability in the grid. Which in turn means renewable targets can be met without such a large impact on security of electricity of supply.
