Mini-grid Policy Toolkit
Introduction
The EUEI-PDF, with Alliance for Rural Electrification (ARE) and REN 21published the Mini-grid Policy Toolkit to provide guidance on how African policy-makers can develop a sustainable mini-grid policy. Such policy should aim at fostering electricity access as well as economic activity based on secure and ideally clean electricity over the long-term.
Problem
The electrification of rural and remote areas is a key component for their economic development. The conventional way to make electric energy accessible for underdeveloped regions is to extend existing grids. As many state budgets for electrification are small and extending grids is very expensive, this method has got some limitations.
Solution
One alternative is to construct mini-grids in areas outside the reach of central grids. These mini–grids generate electricity on a small scale, usually 10 KW to 10 MW. That is enough to supply a certain amount of consumers with electric energy independently from the national electricity grids. Another way is to build stand-alone systems operating with solar energy on small scale. These tools are called Pico-PV Systems and work with usually one or two solar panels feeding some electric devices. Important for the successful implementation of these mini-grids are the right policies. Examples for significant improvements in electric supply triggered by the building of mini-grids are known from Senegal, Mali, Tanzania and Kenya.
Good Policy
The correct policy for mini-grids depends upon their operation model. There are mainly four different models, i.e. operation by utilities, private companies, community-based organizations or a combination of these. Choosing from these models depends again upon national, social and political circumstances and on the dimensions of the mini–grid. As nowadays the public budgets are shrinking, governments try to establish private funding of mini–grid –systems. Major barriers for the usage of mini – grid – systems depend upon socio-economic, political and financial issues. Through designing suitable tariff structures as well as the right subsidy-systems, policy makers can support the successful covering of operation, management and maintenance costs. Furthermore, trough the promotion of a proper framework, politicians can help projects to find private investors who will give them the capital they need to start their business.
Mini-grid Policy Toolkit
In the short and medium run, mini-grid-systems cannot only be financed through private investors, but they need public subsidies as well. The quality of their design decides whether rural electrification projects will be successful or not. It is not an easy task to find the correct way of subsidizing mini-grids or to manage the public investment or to attract private co-financiers for long term and efficient operation of mini-grid-systems. The mini-grid policy toolkit advises public personnel and offers them information with which they can make good decisions.
Mini-grids and Agriculture
Mini-grids can represent a very effective alternative to fossil fuels when using energy for the production of edibles. Lacking access to energy services can slow down the adoption of modern production techniques which ends up in lagging food production and small economic growth. The tight linkage between fossil fuel and the production of food results in a linkage between the fuel price and the price of food. Therefore, the pricing of food becomes somewhat unpredictable. Camco Advisory Services in Cooperation with the Powering Agriculture Initative installed pilot mini-grid projects in some 50 communities in Tanzania. These pilot projects, rolled out in the next 3 years, are based on biomass-exploitation and supply mutliple households with energy, independently from fossil fuels.
