WHAT WE DO

Efforts to incorporate renewable generation and storage into electricity systems globally, and to expand access to electricity in the developing world with new technologies have created a need for new system design and analysis tools.
The Reference Electrification Model (REM), developed by the Universal Energy Access Lab MIT & IIT-Comillas for universal electricity access planning, which for a particular analysis scenario intended by the decision maker, calculates for each customer in the planning area what is, from the techno-economic point of view, the best electrification mode considering a) grid extension, b) microgrid or c) solar kit / stand-alone systems.

Geospatial Planning Tool

WAYA ENERGY’s software tool is a disruptive geospatial electrification data-intensive model. With national or regional data, the model generates the least-cost electrification plan to the maximum level of granularity: household level. It’s a techno-economic optimization considering three forms of electrification: grid extension, mini-grids and isolated systems.

software

 

Our proprietary software tool is a disruptive design ready geospatial electrification data-intensive model which requires the following input information:

  • Grid extension: characteristics and design of the already existing grid, reliability and cost of energy supplied by the grid at distribution level, technical and cost characterization of distribution grid catalogue of components (MV and LV lines, and MV/LV transformers), technical grid codes, cost of non-served energy, other social costs, (smart) end-user connection, financial and administrative costs.
  • Off-grid systems: Technical and cost characterization of the microgrid network (LV lines for microgrids, as well as MV lines and transformers for large minigrids that may require a MV network) and distributed generation catalogues of components (for solar, battery, diesel and hybrid microgrids and stand-alone systems), characterization of solar kits to be distributed to small isolated customers, hourly dispatch for a year of generation and customers demand, local energy resources, technical microgrid codes, cost of non-served energy, other social costs, (smart) end-user connection, financial and administrative costs.

 

 

 

 

 

 

The figure above exemplifies this comprehensive on-grid / off-grid planning approach showing a sample of results for three electrification scenarios of the county of Kilifi in Kenya, using the Reference Network Model. This example shows the different level of penetration of the grid extension according to the reliability of the central network (a) 85%, (b) 95% and (c) 99 %. The existing central network is depicted in black. In (a) 66% of the newly electrified customers are connected to the grid and 21% are grouped in microgrids, the remaining 13% is supplied with a solar kit, and the average per customer investment is 1,356 USD. In (b) 80% is grid extension and 6% microgrids, with a cost per customer of 1,455 USD. Finally, in (c) grid extension reaches 90% while microgrids supply only 2% of the customers. The average cost, in this case, is 1,517 USD. As could be expected, a more reliable network results in an increase of the grid-connected customers, even if the overall cost of connection increases by 10%. Please note that the least-cost planning approach does not compare only system costs, but also the social cost of non-served energy.

This comprehensive planning approach will also support the prioritization of investments for each one of the different grid extension or off-grid projects, according to different implementation phases, considering the availability of investment and operation funding, and the priority areas or energy uses in compliance with the energy and sustainable development policies.

Off-grid DESIGN

WAYA ENERGY’s GIS based software tool allows for detailed technical design of an off-grid site including generation and network layout. 

The ease of use of the software allows for a scalable effort to design tens of thousands of off-grid sites quickly, which can be used to guide a large scale mini-grid program. 

The software has been used to design off-grid systems in India, Uganda, Kenya, Peru, Amazonia, Nigeria, Cambodia and Indonesia.
