Each technology has initial installation costs and recurring production, maintenance and replacement costs.
Mini-grid technologies include a central production facility and a low-voltage distribution network.
The amount of money needed to fund an infrastructure project includes both initial and recurring costs. The initial costs are paid upfront and the recurring costs are paid later.
The net present value or discounted cost of an infrastructure project assumes that you will invest the money that you are not using now. For example, if a $110k project will start next year and if you are confident that you will earn at least 10% through investments, then you can request a loan for $100k one year in advance.
Assume that population grows at a fixed rate each year. If the population is 100 and the growth rate is 10%, then the population will be 110 after the first year and 121 after the second year.
To override a computed value for specific demand points, upload a CSV with an additional column. The column name should match the name of the variable that you are overriding. Variable names are available in the glossary.csv file that is generated after running this tool.
Note that if you leave a blank entry in a local override column, then the system will not override the value for that demand point.
The length of line used to connect two locations is often greater than the distance between the two locations.
Assume that consumption is fixed per capita. Estimate consumption based on the projected population.
To override connection count and consumption by connection type for specific demand points, please use the following column name format in the Demand Point Table above:
For example, the following column names in the Demand Point Table will override household connection count and consumption:
By default, household_connection_count is relative to the size of the population for each year. Overriding household_connection_count will result in household_connection_count being constant year over year.
The following column names in the Demand Point Table will override market count and consumption, but only if market exists as a connection type in the Connection Type Table below:
A remote source produces electricity that is distributed to consumers.
Medium voltage lines carry electricity over large distances.
Medium voltage transformers convert medium voltage to low voltage.
Low voltage lines distribute electricity over small distances.
The low voltage connection connects a building to low voltage line.
A local diesel generator produces electricity that is distributed to consumers.
Generators consume fuel to produce electricity.
The cost model is identical to grid low voltage line.
The cost model is identical to grid low voltage connection.
A photovoltaic system produces electricity from sunlight for each building.
The photovoltaic panel converts sunlight into electricity.
Battery costs are proportional to panel costs.
Balance costs are proportional to panel costs.
A photovoltaic system produces electricity that is distributed to consumers.
