Introduction to technical and economic analysis

With regards to the outcome of the project, we developed a need for an assessment matrix based on some key inputs around the project (which can be seen in the diagram below).  

In order to develop this matrix we had to undergo some technical and economic modelling, which can be seen in subsections above.  The technical modelling included a full power supply and demand analysis of the site which gave us some key data to use for our assessment matrix.  The example tool can be downloaded under the conclusions section and can be used for any other sites looking to do this kind of analysis.  

The matrix was broken down into three main sections; environmental, financial and technical and it was therefore important to look the finances related to the implementation of the new onsite generation.  We found that capital cost and payback where the most important in assessing the different cases onsite.  The economic analysis can also be seen briefly in the subsection.  The diagram below shows the key inputs to the project in order to create a full assessment matrix.

 Grid Interaction – Shows how cases react with the grid. Low interaction indicates less power issues arising from grid

 Percentage Autonomy – Shows how close cases are to obtaining autonomy to be in island mode

 Percentage Match Rate – Shows us how good the technology mix is at meeting demand at every time step

 Financial – Shows us from a financial point of view which cases will be economically feasible

 Environmental – Shows us which how cases compare in terms of the environment
