The next
step was the
implementation of an MCE analysis. For this analysis four
constraints were used. These were the buffers (CityBuffer,
BuildingBuffer, RiverBuffer and RoadBuffer) which were created in the
Methodology section of this project. In combination with these
constraints four factors were included in the MCE. These consist
of the following: slope, distance from a road, distance from the city
center and the distance from the transmission line. |
|
The slope factor was based on a
Monotonically Decreasing Sigmoidal curve. This is based on
the idea that perfectly level terrain holds the greatest value when it
comes to construction and wind supply.
|
|
The road distance factor uses a Symmetric Linear function to take into account the constraints which are also a part of the MCE analysis. The road distance factor is based on the idea that the closed the location is to the boundary of the constraint the less cost there will be to install and service any towers. Furthermore, the proximity to roads will also eliminate the need to construct new roads. After all this form of energy is meant to reduce the harm done to the environment. |
|
This factor takes into consideration the views of the residents of Ashcroft. This factor uses a Monotonically Increasing Sigmodal function as the suitability increase the farther away from the city center the sites are, and the less they will affect the residents. Thus, areas which score higher in the suitability bar are farther from the city center. |
|
The final factor is one which
plays a significant role in determining the cost of any such
project. The factor follows a Monotonically Decreasing Linear
function as the cost would increase steadily over the distance.
The farther away from the grid a turbine is, the more it will cost to
connect it. Moreover, it is rare that the building of new
transmission lines is easily approved by local municipal councils.
|
|
This is the WEIGHT comparison of
the factors which were included in the MCE.
|
|
The weighted ratios produce
these eigenvector numbers for the analysis. As is clearly
visible, the Transmission Line distance is the greatest factor in this
analysis.
|
|
The final results from the MCE analysis provide a very positive response. All areas which appear in colour are suitable locations. Those whose colour matches colours with a higher suitability number |
|
This Ortho map of the MCE
results provides some sense of where in relation to Ashcroft the
suitable locations would be. The hill north of the town center
has met the standards the best and is also closest to the transmission
line. Therefore, the hills surrounding Ashcroft do provide
numerous locations for the installation of wind powered electric
turbines.
