Demand for connections to the Lerwick District Heating Scheme has been greater than we ever envisaged. With a turnover of £1m per year from the sale of heat, it is estimated that some £2m remains in the Shetland economy that would otherwise be spent on imported oil. We are now one of the most successful schemes in the UK and often have people from Britain and Europe visiting our scheme because of the environmental, social and economic benefits it continues to provide.
