Guyana launches series of tenders for off-grid and hybrid solar

The government of the South American nation is seeking to electrify with solar-plus-storage several remote communities through eight different tenders.

Geo-referenced approach to identify communities that can afford PV mini-grids

The novel methodology can be used for 71 countries located across ‘sun belt’ areas of east Asia, South Asia, and sub-Saharan Africa. The model relies on 2014 and 2015 geo-referenced datasets in various formats and spatial resolutions, as well as on a population dataset based on global human settlements (GHSL) and World Bank national-level estimates of electrification.

LCOE of off-grid solar-plus-storage in Russia’s remote areas ranges between $0.19 and $0.29/kWh

Off-grid PV has become a much more viable solution than diesel power generators to bring electricity to Russia’s remotest regions. Furthermore, solar-plus-storage is able to deliver with no interruption 24 hours per day and seven days per week, while fuel availability means diesel power can only ensure between four and seven hours per day.

The Indian market for off-grid solar refrigeration

Standalone solar-powered refrigerators present a $20 billion opportunity in India for vaccine storage, milk chillers, households, micro enterprises, and cold storage for farm produce, according to a new report by Gogla.

New phased microgrid approach for industrial-estate development

Peel Renewable Energy is about to energize a 1.2 MW solar farm in Australia, as part of a fresh approach to microgrids. Infrastructure remains small, but the renewables-powered microgrid can grow to meet the needs of incoming businesses.

Bangladesh mandates 2% of loans issued must be for green projects

Some 15% of the finance disbursed must fit the wider definition of being ‘sustainable’ and banks and other lenders have been warned penalties will be applied for non compliance.

New method to build microgrids based on solar, hydrogen

The use of polymer electrolyte membrane fuel cells as backup power generation in solar microgrids could drive down costs and improve efficiency, according to an international group of researchers. They have proposed a new energy management system that could be ideal for hybrid solar-hydrogen microgrids in remote locations.
