Rooftop Solar’s Potential in Nigeria
India’s experience with rooftop solar and solar farms offers exciting possibilities for Nigeria. The densely populated African country loses 45% of its produce after harvest because it can’t be kept cold, resulting in a 25% loss of income for its 93 million smallholder farmers. A pilot project at a food market in Sokoto, Nigeria, aims to change that by testing the business case for refrigeration fueled by rooftop solar units. If it succeeds, the project will demonstrate the potential of this technology for commercial and industrial consumers – the target market for rapidly scaling up solar rooftop capacity – and transform the lives of millions of farmers.
Creating Solar Markets
After signing onto the Paris Climate Agreement, India began its solar journey in a serious way, facilitating flexible clean power auctions, attracting record-low solar tariffs and underscoring its commitment to clean energy. At the UN Climate Summit in December 2020, Prime Minister Narendra Modi said India is on track to ultimately top its renewable energy targets – hitting 175 gigawatts before 2022.
The World Bank Group’s Scaling Solar program supports a similar auction process in countries like Zambia, to create viable solar markets. The Bangweulu solar plant in Lusaka’s Multi-Facility Economic Zone is expected to supply electricity to as many as 30,000 homes and businesses, complement the country’s hydro-based electricity supply and save electricity purchasing costs for the government.
And in May 2021, Senegal announced through the program that two new solar PV plants will provide access to electricity to nearly 540,000 people at some of the lowest rates in Sub-Saharan Africa. Located in the country’s Western region, the new solar plants in Kael and Kahone will help avoid 89,000 tons of carbon dioxide emissions annually.
Building a Solar Knowledge Exchange
In partnership with the India-led International Solar Alliance, the Bank’s Lighthouse Initiative is supporting a pipeline for the exchange of solar knowledge between Indian agencies and their counterparts in many other countries like Bangladesh and the Maldives and others in Africa.
For example, the Lighthouse Initiative is most active in the Maldives, a nation of over 1,110 islands in the Arabian Sea. Known for its luxury resorts, the Maldives has no proven fossil fuel reserves but remained open for business despite the COVID-19 pandemic, in part because it is making the transition to renewable energy. In December 2020, the Bank approved a $107 million project to help the Maldives accelerate its transition to renewables.
Although geographically and economically diverse, the energy challenges developing countries face reveal common starting points for solutions tailored to each nation’s unique needs. Learning from India’s experiences, whether in small island states or emerging economies in Africa, puts into practice a quotation from Mahatma Gandhi included in India’s 2015 climate target: “One must care about the world one will not see.”
