The research shows that investing in renewable energy and flexibility from gas engines and energy storage is the best way to reduce energy costs, increase energy access and improve grid reliability. With this strategy, the cost of electricity generation is predicted to drop by 74% by 2060 compared to 2022 levels, and carbon emissions will drop to zero.
This in-depth energy modeling exercise also reveals the key role that Nigeria’s domestic gas will play to enable a smooth energy transition. Nigeria’s vast domestic gas reserves can be mobilized as an inexpensive bridging fuel, to power balancing engines in support of intermittent renewable energy generation, until gas engine power plants begin to be converted to run purely on green hydrogen starting in the early forties.
“If the power system expansion roadmap presented to the report is successfully implemented, by 2060 Nigeria’s power system will be fully decarbonised and able to meet the energy needs of our country’s rapidly growing population. The key components of our power system will be renewables, supported energy storage technologies, together with grid-balancing engines that have been converted to run on green hydrogen. As early as 2032, Nigeria can reach universal access to electricity, and the inefficient, expensive, and polluting diesel generators still widely used today will be ancient history,” said Wale Yusuff, Managing Director of Wärtsilä in Nigeria.
However, delivering on this ambitious plan will require enormous investments, estimated at $18.7 Billion until 2030 and $425 Billion until 2060. “Attracting that level of investment is possible, but not without significant policy reforms. Despite the many government efforts to implement an increasingly strong legal framework, project developers and sponsors must still navigate a very complex and uncertain system that adds excessive investment risk,” warned Wale Yusuff.
With its huge gas reserves and high renewable energy potential, Nigeria has all the natural resources necessary to lead the country to a successful energy transition. If the country can improve its power transmission infrastructure, develop a sound policy framework, and deploy a data-driven power expansion plan based on renewable energy and flexibility; it will take a giant step towards its goal of securing universal access to affordable, reliable and fully decarbonised electricity.
