Development of a Regional Strategic Vision involves a high level assessment of the region leading to the development of a number of Opportunity Areas which can then be taken forward to Stage B

The purpose of Energy Masterplanning is to define the scope of the project within the opportunity area outlined in Stage A. This involves the development of hourly energy models and a technology options appraisal and high level whole life costing assessment

Feasibility Stage takes the project opportunity as defined in Stage B and tests the high level technical and commercial assumptions. The definition of the project under Stage B allows for an in-depth interrogation and definition of all aspects of the proposed scheme under Stage C

Building on the work undertaken in Stage D the key financial and commercial aspects of the project can be fully determined in the Business case development phase. Project Governance Structures and Financing Options can be investigated and the market approached.

DISTRICT HEATING IN EDINBURGH

BIOQUARTER STUDY AREA

CATALYST FOR EDINBURGH CITY NETWORK

• Existing and planned heat generation resources “on the doorstep”

• Renewable heat generation supporting City of Edinburgh Council policy on carbon emissions reductions

• New commercial and residential development is planned at scale

• Willingness of stakeholders to consider the role of DH

• Extended network offers cost and carbon benefits to local landowners/tenants including social housing

• A large heat anchor centred on the BioQuarter can grow “organically” towards the City Centre

Data Collection

Develop heat demand map and database of the opportunity area

Strategy

Decide the areas to be connected and the heat supply asset(s) to be used

Technical design

Develop Hourly Energy model for the system

Financial Assessment Project Reporting

Determine the modelling scenarios to be tested

Detemine capital and reinvestment costs for key assetsDetermine fuel costs and other operational and maintenance costsCarry out whole life costing of the project opportunity

Comparative Assessment of the Scenarios

Assessment of each of the modelled scenarios based on the Project Owners' key drivers.Ranking of the modelled scenarios and reccommendations for feasibility assessment.Report key reccomendationsProduce High Level maps of the proposed opportunity Assess the technical supply options for the projectSize key technical assets such as heat network and supply assetsSet out key risks that need to be addressed at feasibility stage

Determine the network route required (if applicable)

Develop supply map, categorise each supply asset
