INTRODUCTION
The decision made before the drawings
A feasibility study answers the questions that determine the whole project: what capacity is required, where the supply should come from, which voltage level is appropriate, and what the investment will be.
Getting this wrong is expensive. A substation sized on optimistic load figures is paid for twice, once when built and again when it is extended.
Method
How the calculation is built
Every figure rests on evidence. Input data comes from the client, and any gaps are closed by measurement and survey.
STEP 01
Load calculation
Present consumption, projected growth and diversity factors are used to establish the required capacity.
STEP 02
Option comparison
Several supply points, voltage levels and route alignments are compared on technical and economic grounds.
STEP 03
Economic assessment
Capital cost, operating cost and payback period are calculated, and the most viable option is recommended.
Object type
Which object needs a study
Select the case that applies and send the enquiry directly.
Mine power supply
Process load at the mine, the capacity increase expected, and the supply line options from the available sources.
Industrial supply
Equipment load, reliability requirements and standby supply arrangements for industrial plant.
Town and settlement supply
Load growth in towns and soum centres, and justification of distribution network extension or upgrade options.
New supply source
Viability of a new substation or generation source, site selection and connection scheme justification.
