mini-grid

Researchers in Sweden investigated the complex non-linear tradeoffs between capacity expansion costs and reliability levels of off-grid PV mini-grids and found that capacity expansion based solely on cost-minimization may result in several reliability issues.

Kenya’s government plans to build 137 solar minigrids across remote locations in the East African country. The project received $150 million in funding from the World Bank.

CrossBoundary EnergyAccess Nigeria has committed to invest $60 million in minigrid projects developed by Engie, in the largest such transaction in Africa. The projects will connect more than 150,000 people to electricity for the first time.

The International Energy Agency’s latest “Africa Energy Outlook” report says grids will need to be expanded, along with natural gas exploitation, if everyone in Africa is to have access to electricity by 2030. On the solar front, the document predicts a levelized cost of energy of $0.018/kWh to $0.049/kWh by 2030 – cheaper than wind power or gas.

Lack of locally-denominated finance, and of sufficiently long-term loans, are well established hurdles to the development of photovoltaics in Africa.

The raised ambition of an already huge renewables-powered hydrogen project in the Southern African nations vividly demonstrates the hydrogen and clean energy potential of a continent which accounted for just 0.5% of the world’s new solar capacity last year, according to trade body AFSIA’s annual report.

While East Africa – and Kenya is particular – has made great strides in the provision of off-grid solar systems, Central Africa is a long way behind, according to a new report from IRENA and the African Development Bank. In terms of investment, the study’s authors wrote, much, much more will be required to achieve universal electricity access this decade.

The Development Bank of Rwanda wants to finance developers to build photovoltaic and mini-grids ranging in size from 10 kW to 1 MW.

The latest edition of a clean power jobs survey produced by IRENA and the International Labour Organization has stressed the important role which will need to be played by the public sector if the energy transition’s employment benefits are to be shared equally.

The move will encourage private sector renewables companies to be part of the national energy industry, a representative of the regulator told a recent webinar which considered how to accelerate clean energy roll-out in Africa.
