Regional Strategic VisionEnergy MasterplanningFeasibility StudyBusiness Case Policy Context and Targets Opportunity Mapping Pipeline of Opportunity Areas Assessment of a single Opportunity Area Testing of Project Scenarios Refinement of Project Definition Confirmation of Assumptions under B Targeted Stakeholder Engagement Commercial Assessment of Project Opportunity Delivery model and structure of ESCO Financial model Finance Options 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. ABCD STAGES OF ENERGY MASTERPLANNING

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
