Lerwick Energy Recovery Plant (Shetland EfW Plant)
The Energy Recovery Plant in Lerwick is operated by Shetland Isles Council which burns over 23,000 tonnes of waste per year and generates 7MW of energy providing heat and hot water for the Lerwick District Heating System which is operated by the Shetland Heat Energy and Power Ltd (SHEAP)[1] [2].

Summary
The Energy Recovery Plant in Lerwick is operated by Shetland Isles Council which burns over 23,000 tonnes of waste per year and generates 7MW of energy providing heat and hot water for the Lerwick District Heating System which is operated by the Shetland Heat Energy and Power Ltd (SHEAP)[3] [4].
The waste to feed the plant originates from Shetland, Orkney and areas of the Highlands.
The hot water created from the destruction of the residual waste is used to heat approximately 1,230 domestic properties, commercial and public buildings around Lerwick including schools, care homes, the leisure centre and hospital[5] and distributed around the town via insulated pipes.
History
The facility has been operating successfully in Shetland since 2000 burning predominantly Household, Commercial and Industrial wastes and is the smallest of all the Local Authority Energy from Waste plants currently operating in the UK.[6]
Plant
The thermal efficiency of the plant in terms of heat recovered is 80%. The capital cost of the plant was approximately £10m and the district heating network a further £11.5m. The cost of installing the heat exchangers per propoerty to allow the heat to be used was between £2,000-£5,000.[7].
The Shetland EfW facility has an anticipated life span of 10-15 years under current maintentance programmes[8]
Local Authority Data
The table below lists those local authorities who have recorded their tonnage on WasteDataFlow as sending their Waste to this site (either directly or via a transfer station) for the most recent financial year, data was updated on Error: no local variable "updated" has been set.. The tonnage received cannot be directly compared with the stated historical tonnage received and recorded in the EA statistics as these are recorded on a calendar year basis (i.e. January 2018 to December 2018). The total Local Authority waste received by the plant in the period was: 0t
A 'zero return' or a below expected return, when compared to the EA Data below indicates that either:
- no local authority tonnage was recorded/no tonnage was sent to the site in the period (but has been listed as it may have previously received tonnage from a local authority) or
- a result of the plant being recently commissioned and actually having received no tonnage or
- a lower than expected tonnage maybe a result of a local authority splitting their tonnage over multiple sites, having less tonnage to send than might be anticipated or
- it may be a new plant being in 'ramp up' towards full capacity after construction or
- may be a result of plant shut down and subsequent re-start in a year or
- the local authority may not have correctly entered the site's details on WasteDataFlow

Waste Tonnage, By Origin
The table shows a list of the Waste for the Permit PPC/A/1003141, that has arrived into sites as reported to the Regulator and then publicised in their reported statistics. The Data was last updated on October 2023. The total reported tonnage arriving at the site was: 11,398.16t. Where this tonnage exceeds that reported in year of the corresponding annual report, this may be due to the following reasons:
- Tonnage may have been received but not incinerated, i.e. the material is held pending incineration (the operator return to the EA reports as received whereas the annual report focuses on when the waste is incinerated.)
- Material may have been received into the site but treated in some other way than incineration.
- Material may have been received on the but transferred out of site for disposal/treatment at another site rather than incineration on the site.
