Alternative Energy To Improve Nigeria’s Grid System- AIIM

The African Infrastructure Investment Managers has called for intensified and a deliberate investment in alternative energy sources by Nigeria, to free industries and other heavy electricity consumers from weak grid system.

“Natural gas has a vital role to play alongside renewables” in Africa, African Infrastructure Investment Managers’ (AIIM) managing director Sola Lawson told Energy Voice.

“We’re working to make sure that what we do is in tune with what our investors want,” Lawson said. Gas-fired generation provides dependable baseload, noting that the recommended level of renewable energy in a grid is around 20-25 per cent.

AIIM has a strategy of investing in natural gas projects that “assist with effecting a clear transition from higher-cost, higher-carbon to lower-cost, lower-carbon fuel sources”.

The two major markets are Nigeria and South Africa both of which hold strong potential in shifting away from higher carbon sources.

Installed power capacity in Nigeria is around 12 GW, Lawson said, although only 4 GW is actually available and as a result, people seek alternative sources of generation in order to meet their needs.

“There’s around 19 GW of diesel generation capacity in Nigeria. That’s a vast amount of diesel. You can substitute this with gas, and layer on renewables, cutting costs and carbon,” the AIIM executive said.

Renewables, specifically solar, can work to replace household or business diesel generators. “Nigerian customers, worried about the reliability of the grid, have wanted a generation source behind the meter on their premises. Given the rapid drop in the price of solar and batteries, that can be priced at a discount to diesel.”

The question of cost is critical. Customers take a decision on whether to opt for diesel or solar only because of cost. As prices of solar and batteries have fallen, the economics of opting for the renewable source “have become compelling”, Lawson said.

“Governments could take steps to encourage that, cutting duties on solar panels for instance. There is massive scope for power substitution.”

Increasingly, investors such as AIIM will opt to work with companies rather than governments, particularly given pressure on state budgets linked to COVID-19. The pandemic has reduced the flow of cash to governments, which is translating into delayed payments – and even the possibility of defaults.

This all acts to make the case for a move away from centralised grid power.

“Corporate offtake is becoming increasingly common. There’s an increasing acceptance that this model provides more regular cash payments than trying to gold plate a structure with a utility that is struggling,” Lawson said. “Credit quality is the key.”
