Introduction ▼

Good day,

My name is __________. We are researchers from the University of Lagos, Akoka, Yaba, Lagos, working with colleagues from six African countries and the United Kingdom on the adoption of renewable microgrid technologies in Africa.

In Nigeria, the project is led by the Circular Economy Powered Renewable Energy Centre (CEPREC), represented by the University of Lagos. Renewable energy currently accounts for about 21% of Nigeria’s electricity use, with recent declines as households faced lower incomes and rising unemployment. Solar and wind power make only a negligible contribution.

CEPREC aims to understand consumer preferences for renewable solutions powered by second-hand electric vehicle batteries, alongside small solar, hydro, and wind installations. These circular microgrids can improve electricity access and reduce dependence on the national grid.

Your participation will provide evidence for policymakers to support Nigeria’s energy transition. There are no known physical risks. Participation is voluntary, and you may skip questions or withdraw at any time without consequence.

The questionnaire will take about 20 minutes. All responses are anonymous, strictly confidential, and used only for research. Results may be published in academic journals or presented at conferences in the UK and internationally.

For more information, contact Prof. Muyiwa Oyinlola at muyiwa.oyinlola@dmu.ac.uk.

By clicking “Start Survey”, you confirm that you have understood the above information and that you consent to taking part in this survey.

Section 4: Choice Experiment

Consider the following hypothetical situation. You are exploring renewable energy options for your household through a circular microgrid. These systems are designed to last for 10 years and require significant investment. The installation in your area will be financed by private and government funders, and repayment will be spread over 10 years. The repayment cost will be added to your current electricity bill. You will be asked to choose your preferred circular microgrid from three (3) options. Two options will vary in their features, such as:

How many devices you can power with the extra electricity generated, and
The type of renewable energy sources used.

Each option will have an additional monthly cost, shown in Naira (₦), added to your current electricity bill. If none of the options suit you, you may choose “No circular microgrid,” which means your household will receive no extra electricity.

Please answer each question honestly, considering whether you could afford each option.

The first of the eight sets of options will now be shown to you. In similar surveys, participants have often reported a higher willingness to pay for electricity than they choose when such policies are introduced in real life. The results of this survey will be shared with energy sector policymakers in Nigeria and could influence future electricity prices and policies.
