Nigeria, Africa’s biggest oil exporter, may be about to turn sunward to generate more of its power. Senators in the capital of Abuja are currently debating whether they’ll allocate $30 million to solar projects in this year’s budget, according to the Renewable Energy Association of Nigeria. They’re expected to provide funding for off-grid solar projects, photovoltaic manufacturing, and transmission upgrades, according to REAN Executive Secretary Godwin Aigbokhan. Their decision is expected this month. “It just gives you an idea of how the government sees solar as part of the total energy mix,” Aigbokhan said in a telephone interview from Lagos. The country could receive about $2.5 billion of investments in utility-scale solar projects by 2018, he said. Just four months after Nigeria announced plans to issue green bonds for renewable-energy projects, West Africa’s biggest economy is debating how it could deliver clean power to more of its 180 million citizens. Officials say they want to generate as much as 1,200 megawatts of off-grid solar. Nigerian households and small businesses currently spend about $21.8 billion each year powering diesel generators to generate electricity, according to a study by German development agency GIZ.  Nigeria Uses Fossil Fuels for Electricity “The ubiquity of small diesel generators used to bridge gaps in grid-supplied power already makes solar panels that cut fuel costs an economic option,” said Itamar Orlandi, head of frontier power research at Bloomberg New Energy Finance.  Project Activity Nigeria has said it wants to increase the contribution of renewables to its energy mix to 23 percent by 2025, from 13 percent in 2015. Interest in solar has already increased, with more than $50 million of Chinese photovoltaic panels imported in the last two years, according to BNEF. In January, the Niger Delta Power Company signed an agreement with Azuri Technologies to provide power systems for 20,000 rural households living without access to the grid. Nigerian Vice President Yemi Osinbajo said the deal underscored the government’s commitment to providing access to electricity. Nigerian policymakers, who already privatized state power assets in 2015, are continuing to formulate incentives for utility-scale solar investors, according to REAN’s Aigbokhan. “There are put-call option agreements in place and partial risk guarantees, so what should stop a foreign investor coming to Nigeria,” he said.
