Off-Grid

Indonesia’s Central Bureau of Statistics reported in 2018 that 2,281 villages had no access to electricity. With more than 17,000 islands, building grid connections between them would be expensive. So what are the key challenges and solutions to the development of rural area electrification in Indonesia? pv magazine interviewed three experts that are involved in developing the country’s rural area electrification.

The French development agency and the environment ministry have a €1.6 million budget to finance novel off-grid projects from companies and NGOs operating with local partners in Africa.

The invention converts the energy produced by PV cells directly into mechanical motion without the need for batteries or power electronics. Its developers claim the robustness of the solar motor can drive water pumps and ventilation turbines for more than 20 years without the need for maintenance.

The new credit lines are for the development of on and off-grid renewable energy projects. The European Commission is offering the fund a €40 million helping hand.

Although only two of the nine projects selected in the auction are for hybrid biomass-solar power plants with some storage, seven will rely on renewable energy sources. The largest selected project, however, is a 123 MW gas power plant in the city of Boa Vista.

The off-grid solar system supplier has received the finance in Rwandan francs to mitigate currency risk and expand operations in its biggest market.

No more than four hours per day, did the 160 households enjoy energy supply. This has had negative impacts on the economic development of the islands. With support from the ADB, the island inhabitants now have 24h supply of clean energy, and new billing methods that suit the economic realities of poorer households.

Australia’s Coalition government has announced funding to support up to 50 off-grid and fringe-of-grid feasibility studies that will investigate whether building a microgrid is cost-effective and whether existing off-grid capabilities can be upgraded with more up-to-date technology.

A new report from U.S. based Rocky Mountain Institute outlines the potential for minigrid deployment to provide electricity to underserved communities around the world, to the benefit of utility companies, minigrid developers and communities. The report takes examples from Nigeria to illustrate this potential, but states that many of its findings could be applied to communities with limited or no access to electricity around the world.

Australian mining company Resolute Mining has inked a JDA and PPA with Ignite Energy, to construct what it says is the world’s largest off-grid solar hybrid plant, at one of its gold mines in Mali.
