Tender description

This is the first phase of frameworks to support decentralised Energy Networks. Key features: (a) This phase will cover the Technical and Professional Consultancy element, i.e. services. Future frameworks will cover Supplies and Works; (b) Contracts will be awarded by Stoke-on-Trent City Council. However management of the frameworks will be via a Central Purchasing Body called Sinfra (UK), effectively a franchise of the Swedish purchasing body Sinfra. Contracts will be novated from the Council to Sinfra (UK); (c) The frameworks will be made available to other authorities, universities and hospital trusts; (d) Coverage will be UK wide. The consultant is required to collect and collate data as part of an energy mapping and modelling study, and present the data digitally on a suitable GIS base. As a minimum this will require extensive: — Analytical and data management skills (including the ability to identify sufficient accuracy of peak energy demands and annual energy consumptions for heat, cooling and power, — Geographic Information System (GIS) skills. It could also require the following capabilities (either directly or via supply chain/sub-contractor): — Low carbon energy specialists, — GIS analyst to undertake a modelling of energy (heat, cooling, power) demand calculations and calculating building footprint areas, — The ability to train customers in using GIS systems, — The ability to identify and incorporate Planning and other constraints (flood risks; protected highway corridors; Scheduled Ancient Monuments etc), — Master-planning. The consultant is required to assess local opportunities for assessing the commercial, technical and economic feasibility of a decentralised energy network, including sources of heat, cooling and power generation, as well as potential customers, and develop a strategy to create commercially and technical viable solutions in a given boundary area. The outcome of such activity is a whole life cost-benefit analysis of whether a given investment in a heat network or decentralised energy system is feasible from an economic and/or environmental and/or social point of view. A successful supplier will be able to: — Assess the feasibility of a district heat network project and/or decentralised energy system from a technical physical point of view, — Evaluate the most appropriate technologies to use, — Based on the above, provide budget costs for the initial capital investment required for such a scheme, — Identify the likely cashflow, i.e. operational income and expenditure of such a scheme, — Based on the above analysis, make recommendations (including options appraisal). It could also require the following capabilities: — Provision of commercial advice to clients in negotiating Heads of Terms and key agreements, — Provision of specialist cost advice, including tax and other accountancy strategies, — Calculation of social costs/benefits, e.g. reducing fuel poverty, — Calculation of environmental costs/benefits, e.g. CO2 reduction.
