Micro-grid - Suriname

Project’s Introduction

  • Date: July 2018 to April 2019

  • Project: Development of Renewable Energy, Energy Efficiency and Electrification for Suriname

  • Donor: *Global Environmental facility (International)**, *Inter-American Development Bank (Americas)

  • Implementing Body: Ministry of Natural Resources (Suriname)


The Republic of Suriname has received financing from the Global Environmental Facility (GEF) through the Inter-American Development Bank for the operation Development of Renewable Energy, Energy Efficiency and Electrification of Suriname. The general objective of The Program is to promote the use of renewable energy and energy efficiency technologies in the urban and rural areas and increase access to energy in the interior of Suriname with the intention of reducing the sector’s emission of greenhouse gases.

The specific objectives of this consultancy are:

  1. Design an applicable business model, tailored to the local socio-economic reality of the community, that can also be replicated for future RET initiatives.

  2. Supervise the Ministry of Natural Resources in the preparation and execution of procurement of goods and services required for the implementation of the business model.

  3. Train the Department of Rural Electrification of the Ministry (DEV) and local village participants in the implementation of the business model.

  4. Supervise the implementation of the business model in the pilot RET project.

Prodegee’s Implementation

Prodegee was used to factor all the input data and propose a suggested tariff for the mini-grid. The proposed tariff was tested under different scenarios based on the following variables:

System design variables:

  • Plan capacity: 150kWh, 180kWh and 200kWp

  • Type of mini-grid: Hybrid system with power generator or just solar generation

Performance variables:

  • Effective life of the components: very short, short or optimal, depending on the quality of the preventive maintenance performed.

Macro-economic variables:

  • Price inflation: stable (0%), low (6%) and high (14%)

  • Exchange rates: high depreciation of the local currency, low depreciation or constant.

  • Cost of battery replacement: one option was at half the current cost because of technological improvements and the other at the same current cost.

  • Deposit rates for local currency: withthe options being no interest, low interest (4%) or medium (9%).

All these scenarios were factored in the Dashboard, allowing to change scenario by simply selecting a different option. This allowed for a sensitivity analysis to be carried out for the proposed tariff under each combination of scenarios.

Dashboard Suriname

Once used for a single mini-grid, Prodegee could be used for projecting the financial statements of all the 150 mini-grids that government would like to install in the interior according to different business models and clustering of the mini-grids in regions. It could be even used to factor the entire power sector of the country, as it did in Sierra Leone
