The sale of electricity as a second tier supplier may be of particular interest to CHP/CH schemes because there will be the opportunity to market heat and electricity together to customers on the community heating scheme. Selling two utility services may also bring benefits in metering and charging arrangements. This option is therefore discussed further below. If a CHP/CH scheme is to undertake to sell electricity direct to customers, additional arrangements will be required, for example:

• a top-up and standby purchase arrangement for times when the generation is less than customer demand (including times of CHP plant outage); as a pool member a second tier supplier can purchase this power direct from the pool

• a contract for selling spill power for times when more power is generated than customers demand

• either the payment of use-of-system charges, the purchase of existing electricity infrastructure or the installation of new cables in order to transfer power to the customers.

In the domestic sector, the creditworthiness of customers should be considered and the possible need for a form of prepayment. The management of debt collection is a customer care issue, and disconnection policies need to be fully developed if customers are to be retained in the long term.

3.8: Development Programme

An important output from the feasibility study is a development programme. This is required first to permit the construction of cash flows for capital expenditure, and second to enable advance planning of subsequent stages. A separate, more detailed programme may be produced covering the period of development from the conclusion of the feasibility study to the start of construction, if the route to achieve this is sufficiently clear. It is also worth establishing a watching brief on all work involving renewal of underground services, so that opportunities may be taken to coordinate projects, thus reducing costs and disruption. Issues to consider when drawing up the programme are:

• the need for a further project definition stage

• the need for further site surveys and investigations

• consultation with customers and adjacent building owners and residents

• planning applications (and associated environmental statements)

• Building Regulations applications

• energy rating and emission improvements

• preparation of invitations to tender

• tender period

• short-listing construction companies

• short-listing energy developer companies

• short-listing operating companies

• assessment of tenders and final negotiations of contracts

• mobilisation

• site clearance

• construction

• commissioning and testing

• operation and maintenance.

Supervision during construction is of paramount importance in order to secure the necessary quality of system. 本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
