Off-Grid

Global actions delivering electricity for rural households through off-grid renewable energy

The Sustainable Development Goal set forth in SDG 7.1 calls for universal access to affordable, reliable, and modern energy services by 2030. It is estimated that currently 789 million people do not have access to electricity in their homes or communities. Rural inhabitants encompass 80% of the total number of people lacking household electricity access. On a global scale, rural inhabitants have been gaining access to electricity at a rapid rate over the past couple decades (IRENA 2020, 23). However, certain regions have seen little improvement in this area. Sub-Saharan Africa (SSA) is the starkest example.

How end-user subsidies can help achieve universal energy access

In a recent GOGLA discussion paper, 25 GOGLA members discussed the way forward on how end-user subsidies can be modeled to accelerate universal energy access in underserved markets.

‘There has never been a better time for hybrid microgrids’

In a move that’s sure to pan out well for the Granny Smith gold mine in Western Australia, Aggreko has installed one of the country’s largest renewable energy microgrids, with 7.7 MWp of solar to be integrated with the site’s existing power station. pv magazine recently sat down with Karim Wazni, Aggreko’s managing director of microgrids and storage solutions, to discuss how microgrids and energy storage can help transition Australia’s resource sector.

India tenders for Himalayan off-grid solar and storage

The Solar Energy Corporation of India has issued a call for expressions of interest to supply clean energy to isolated off-grid communities and warned components will probably have to be transported manually.

Sizing standalone solar-plus-storage with nomograms

A Spanish-Dutch research group has created nomograms for PV system sizing that not only offer a standard calculation tool but also provide additional information about what-if scenarios with higher-level knowledge about price of modifications and limitations of project sites.

Australian-designed storage system spells grid independence

“We’ve put together the best components to make a unique Australian-designed solution that is compliant to the new battery standards,” says EVO Power Managing Director Jamie Allen. Offgrid or upmarket – just add solar.

US installed more microgrids in 2019 than ever before

Most microgrid projects still feature distributed fossil fuel generation, but the share of renewable microgrids is rising, driven by high-volume adopters such as the Red Cross.

The weekend read: Expand and connect

Almost 60% of Nigeria’s population currently has access to electricity. But this breaks down as 78% in cities and urban areas, and just 39% in rural communities. The Rural Electrification Agency (REA), established by the government as part of electricity sector reforms in 2005, is tasked with bridging this gap and bringing reliable energy supply to the most remote parts of Nigeria. pv magazine spoke with REA CEO Ahmad Salihijo Ahmad about the organization’s strategy and recent progress, as well as the challenges that remain for rural electrification in Nigeria and the role of PV technology.

Off-grid Brazil: extending beyond isolated communities

The Brazilian power grid reaches approximately 99% of the country’s population. To connect the remaining 1% has been challenging – often located in isolated communities of regions that are difficult to reach. With increasing global adoption of solar+storage, and significant price drops across the two technologies over the past decade, the solution is showing promise for the remote Brazilian market. Solar+storage is becoming a more competitive solution than its most popular alternative – diesel – to supply the needed power for off-grid communities. And now, even grid-connected residential properties are opting for independence.

Shedding lights on Indonesia’s off-grid sector

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.
