Description

The City of Edinburgh Council is currently progressing an Outline Business Case for a low carbon heat network to serve the Granton Waterfront development and existing buildings identified in the surrounding area. The Council expects to invite parties to bid to design, build, finance, operate and maintain the low carbon heat network under a concession model. The Council has published a Prior Information Notice as a market consultation exercise to give potential bidders the opportunity to shape the Council’s procurement strategy and delivery model. Potential bidders who are interested in this opportunity are invited to download the market research questionnaire and complete no later than 27 January 2023.

Total Quantity or Scope

The Granton Waterfront development is anticipated to deliver around 3,500 homes (over 1,000 of them affordable), a primary school, a medical centre and over 9,000m2 of commercial, retail, and leisure space. Around 750 homes are expected to be delivered as part of the first phase of the development. As part of the development and to work towards meeting the target of Edinburgh achieving net zero carbon by 2030, the council wishes to progress the delivery of a heat network that will supply cost-competitive low carbon heat to new and existing households and non-domestic properties throughout Granton Waterfront and the surrounding areas, where deemed viable. This Prior Information Notice focuses on the delivery and operation of the low carbon heat network to serve the new Granton Waterfront development and existing identified buildings in the Granton area. However, the Council is considering the inclusion of extension options with the successful heat network operator for other potential heat network projects in Edinburgh. This information will be contained within the Contract Notice. The current preferred solution identified for the low carbon heat network, following feasibility work and initial business case work is to source heat for the network from a wastewater source heat pump utilising heat from sewers. The network would utilise a sewage heat recovery system, with a ground-mounted solar PV array helping meet the system’s electricity requirements. The heat would be distributed via a network of approximately 7km (depending on network routing and phasing of connections). The indicative network identified as the preferred option for OBC development is the maximum potential scheme serving the core Granton Waterfront development plus additional customers to the south, west and east. This preferred option represents an annual heat demand of c.25,055 MWh. The Council and its advisers are engaging with the public sector customers identified in the preferred option including Edinburgh College, National Museum of Scotland and National Galleries of Scotland. The opportunity is expected to be advertised later in 2023. This market consultation exercise is an opportunity for potential bidders to participate in shaping the Council’s procurement strategy and delivery model. … Potential bidders who submit a questionnaire may be invited to a dialogue/question and answer session with the Council to expand on their response.
