This project falls under the public utilities category and is located in County Durham, England. The tender is currently in the active stage, with submissions due by 16 December 2021. The estimated value of the contract is £45 million, and the selected contractor will provide low carbon heat sourced from mine water for the Seaham Garden Village development, which will encompass approximately 1,500 homes and associated amenities over a ten-year period. This tender presents significant growth opportunities for businesses specialising in sustainable energy solutions, particularly those with expertise in geothermal heating and district energy systems. Companies that offer innovative, low-carbon technologies and can efficiently harness mine water as a sustainable energy source would be well-positioned to compete in this procurement process. The successful contractor will not only contribute to an environmentally friendly heating solution but also play a crucial role in re-purposing abandoned coal mines into valuable energy assets for local communities. ## Notice PLEASE ACCESS DOCUMENTS VIA www.nepo.org using ref : DN581653 ALL DOCUMENTS ARE AVAILABLE ONLINE PLEASE DON'T CONTACT THE BUYER DIRECTLY This contract is for the supply of low carbon heat from mine water to the Seaham Garden Village development. The site of the proposed Seaham Garden Village development is adjacent to the Coal Authority's Dawdon mine water treatment scheme. This scheme protects vital drinking water abstraction from Durham Magnesian Limestone, and pumps up to 150 litres of mine water per second to the surface for treatment. This mine water is warmed by geothermal processes to provide a continuous supply of water at 18 to 20degC. With mine water temperatures unaffected by seasonal variations, there is a potential for low cost, low carbon sustainable energy to be made available for local space heating and hot water throughout the year. The Coal Authority is advancing plans to convert the UK's abandoned coal mines from a liability to an asset of strategic importance to the UK. Dawdon is just one of 75 mine water treatment schemes across the UK that the Coal Authority operates. In total these schemes release circa 100MW of geothermal energy to the atmosphere that could be used for heating purposes. 25% of homes and businesses in the United Kingdom are in the coalfields and 9 of the 10 largest UK urban areas are over or adjacent to abandoned coal mines. This means that the Seaham Garden Village scheme has the potential to pave the way for the large-scale proliferation of mine energy district heating schemes across the coalfield communities. DCC has granted planning permission to construct a new development of approximately 1,500 homes and associated amenities (school and other community buildings) at Seaham Garden Village, County Durham, to be built across a 10-year period. The Coal Authority became aware of the development and identified it as a site of high potential for mine water heating, due to its proximity to the Dawdon mine water treatment plant, in line with their strategic goal of re-purposing abandoned mines for heating. ## Key Details | Field | Value | | --- | --- | | Publication source | Contracts Finder | | Latest notice | https://www.contractsfinder.service.gov.uk/Notice/ab7e469b-a716-4a4c-8a56-15f4f3df8e15 | | Notice type | Tender Notice | | Procurement type | Standard | | Procurement category | Works | | Procurement method | Selective | | Procurement method details | Negotiated procedure | | Tender suitability | Not specified | | Awardee scale | Not specified | | All stages | Tender | ## Dates | Field | Value | | --- | --- | | Publication date | 22 Nov 2021 | | Submission deadline | 16 Dec 2021 | | Future notice date | Not specified | | Award date | Not specified | | Contract period | 31 Jul 2022 - 31 Jul 2062 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £45,000,000 | | Lots value | Not specified | | Awards value | Not specified | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Active | | Lots status | Not specified | | Awards status | Not specified | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | DURHAM COUNTY COUNCIL | | Locality | DURHAM | | Post town | Durham | | Postcode | DH1 5UQ | | Country | England | | ITL 1 | TLC North East (England) | | ITL 2 | TLC4 Northumberland, Durham and Tyne & Wear | | ITL 3 | TLC41 Durham | | Local authority | County Durham | | Electoral ward | Neville's Cross | | Westminster constituency | City of Durham | | Delivery location | TLC North East (England), TLD North West (England), TLF East Midlands (England), TLG West Midlands (England), TLH East (England), TLJ South East (England), TLK South West (England) | ## CPV Codes ### Divisions - 65 - Public utilities ### Codes - 65000000 - Public utilities ## Release History - 22 Nov 2021 at 10:21 - Tender - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/ab7e469b-a716-4a4c-8a56-15f4f3df8e15 - 16 Nov 2021 at 15:55 - Tender - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/6b8aa3ab-eb48-4dc3-80af-78d796b16c60 ## Documents - https://www.contractsfinder.service.gov.uk/Notice/ab7e469b-a716-4a4c-8a56-15f4f3df8e15 22nd November 2021 - Opportunity notice on Contracts Finder - https://www.contractsfinder.service.gov.uk/Notice/6b8aa3ab-eb48-4dc3-80af-78d796b16c60 16th November 2021 - Opportunity notice on Contracts Finder ## Notice URLs - http://www.durham.gov.uk ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
