How Nigeria can become a solar super power, by Patrick Owelle

Dr. Patrick OWELLE is a Solar Energy Scholar/Research Fellow. He is currently the Managing Director of PSC SOLAR UK Limited based in Lagos. He believes that “with the right policies in place, Nigeria can easily become a “Solar Super Power”

THERE is a “Green Energy Revolution” underway in Nigeria that can increase prosperity for millions of poor families by harnessing the abundant and clean energy of the sun.

With the right policies in place Nigeria can easily become a world leader in solar energy.   This solar endeavor could also help address acute power shortages, and make a real difference in slowing the pace of climate change.

Since being elected in May 2015, President Muhammadu BUHARI and Vice President , Prof. Yemi Osinbajo have outlined the government’s vision for increasing Nigeria’s renewable energy capacity, including a boost in solar power generation from virtually zero to 70 GW.

The plan is to achieve these targets by 2020. But to do so, Nigeria needs a National Energy Policy, Regulatory Programs and innovative financing mechanisms that encourage the development of distributed energy, particularly, applications that combine solar generation with energy storage.

Financing mechanisms

Nigeria has already taken positive steps by announcing very aggressive goals to meet 40 percent of its energy needs through renewables by 2020. I firmly believe that, with favorable policies and strategic economic investments, Nigeria could meet all of its energy needs through renewables by 2040.

At the recent signing of the Nigeria/UK Solar Energy Partnership held in London on October 22, 2015, the Nigeria Vice President stated – “Nigeria will be the place where all of the example will be set for the rest of Africa. We are really looking forward to.”

Solar Power Potential in Nigeria

Nigeria is endowed with abundant free solar energy. Using the country’s deserts and farm land and taking advantage of 320 to 350 sunny days a year, Nigeria could easily generate 5,000 trillion KWh of solar energy.

In other words, Nigeria could easily install around 1,000 GW of solar generation — equivalent to 40 times the current peak power demand (about 25 GW) — using just 0.5 percent of its land. In addition, Nigeria can produce over 100 GW from wind power.

As economist and activist Jeremy Rifkin said, while speaking in Lagos in March 2012: “Nigeria is the Saudi Arabia of renewable energy sources and, if properly utilised, Nigeria can realise its place in the world as a great power — but political will is required for the eventual shift from fossil fuels to renewable energy.”

Nigeria is both densely populated and has high solar insulation, providing ideal conditions for the exponential growth of solar power as a future energy source. With GDP growing at about seven percent, solar PV is the only renewable energy resource that can bridge the ‘gap’ between supply and demand.

Solar energy can transform Nigeria and help to bring about decentralised distribution of energy, thereby empowering people at the grassroots level and eliminating the need for costly expansion of transmission and distribution systems.

How can Nigeria achieve its economic, environmental and energy goals?

For Nigeria, a combination of solar power and energy storage is the answer to true energy independence. For its part, the Nigerian government has taken several measurable steps toward improving infrastructure and power reliability but, more needs to be done — and fast. Along with expediting the adoption of solar and other renewable energy resources, to secure its energy future Nigeria urgently needs to implement innovative policies and financing mechanisms (such as capital and interest subsidies, viability gap funding, concessional finance, etc.) to promote increased use of abundant, sustainable, solar energy. Recent Solar Power projects agreement signed by VP Yemi Osinbajo with UK Government/DFID and French Solar Powerhouse, Vergnet points to the seriousness of engagement in Solar Electricity by the Current Administration.

In addition, micro-grids have the potential to change the way communities generate and use energy, can reduce costs, increase reliability and improve environmental performance. Micro-grids can be used to take substantial electrical load off the existing power grid and so reduce the need for building new or expanding existing transmission and distribution systems.

By implementing the following 10 strategies, Nigeria can begin to become a “Solar Super Power”:

*Develop National Renewable Energy (RE) Policy – Enact and deploy a comprehensive new energy roadmap or innovative RE policies (e.g., PPAs, Net Metering, FIT, etc.) without delay. In addition, set National Renewable Energy Standards/Policy such as 20 percent by 2020, 40 percent by 2030 and 100 percent by 2040 — to create demand, new industries and innovation, and a new wave of green jobs.

*Invite international developers to meet the revised government targets of 70 GW of Solar and 75 MW of Wind by 2022 and beyond.

*Electrifying transportation – Expedite a move to electrify transportation by encouraging expanded use of Electric Vehicles (EV) and plug-in hybrids, and deployment of solar-powered EV charging stations around the country.

Transportation system

Develop and implement time-of-day pricing to encourage charging of vehicles at night and other times when peak demand is low. In addition, launch the public transportation system of the future with zero-emission battery-powered Electric Buses in all major cities to reduce air pollution and reverse climate change.

*Energy efficiency – Make Energy Efficiency a high priority by expediting the development and implementation of cost-effective energy efficiency standards. To reduce the long term demand for energy, engage states, industrial companies, utilities and other stakeholders to accelerate energy efficiency investments such as large scale nationwide use of LED lamps.

*Utility-scale projects – Phase out conventional energy subsidies, and develop a long term plan to replace fossil and nuclear plants with utility-scale renewable generation.

*Innovative financing solution – Provide innovative financing (including Tax-Free Solar Bonds or Green Infrastructure Bonds, accelerated depreciation mechanism, and access to credit at globally competitive rates, etc.) to instill more confidence from potential investors and decrease the cost of financing for renewable energy projects.

Energy projects

Create and fund a national smart infrastructure bank for renewable energy.

*Develop large-scale “Solar Manufacturing Hubs” in Nigeria to facilitate mass production of PV, CSP and CPV equipment.

*Decentralised energy – Avoid future fossil fuel investments in Nigeria and, instead, emphasize nationwide deployment of community scale solar projects (installing 100 million solar roofs, solar co-operatives, and solar cities, etc.) and micro-grids with storage. Nigeria’s present virtually non-existent solar target should be extended to include photovoltaic panels on the rooftop of every home in Nigeria, generating enough power to reduce the country’s massive dependence on fossil fuels.

*Develop energy storage including thermal, grid battery storage (e.g., Tesla Powerwall home battery backup), compressed air/gas, vehicles-to-grid/home, pumped hydro, fuel cells or hydrogen (H2 – produced from renewable energy only), flywheels, superconducting magnets and super capacitors.   Develop a “hydrogen economy” plan. If done successfully, hydrogen and electricity will eventually become society’s primary energy carriers for the 21st  century.

*Establish R&D facilities within academia, research institutions, industry, government and private entities to guide technology development in Nigeria.

Nigeria’s clean energy targets are realistic, desirable and fully achievable. All that is needed now to make this concept a reality is political commitment and appropriate investments and funding for building many more solar power systems, solar farms, hybrid solar-natural gas plants, solar thermal storage and advanced battery-based grid energy storage systems.

Excess energy generated from solar could be stored in various forms and then used during times of peak demand. Investment in those technologies would provide an economic stimulus of at least $1 trillion, and perhaps much more if all indirect effects are included.   Given its abundant sunshine, Nigeria could even use solar power to produce “solar fuels” (e.g., using electrolysis to extract hydrogen from water), which could be exported to meet the voracious demand for clean energy from neighboring African economies.

Solar energy provides a golden opportunity for Nigeria to move toward a 100 percent clean energy future while reducing poverty, ensuring energy security and combating climate change.   Solar energy has the potential to propel Nigeria forward as a “Solar Super Power.”   However, for Nigeria to meet its future energy needs, it can no longer afford to delay deployment of solar energy.
