Decentralised Energy Network Frameworks (Phase 1: Technical and Professional Consultancy)
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,

Commercial and Techno-Economic Feasibility
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.
