Lagos is the largest solar market in Nigeria and the commercial centre of West Africa. The C&I solar opportunity in Lagos is driven by two converging forces: DisCo electricity supply that averages 4–8 hours per day in most commercial areas, and diesel generation costs that reached ₦300–₦450/kWh following the 2023 fuel subsidy removal. Solar + battery has become the primary energy solution for hotels, factories, hospitals, offices, and shopping centres across the city.
The compliance framework in Lagos combines federal NERC requirements with Lagos State building and planning approvals. This guide covers the DisCo-specific requirements for both Ikeja Electric and EKEDC, LASBCA building permit requirements, the Lagos State policy context, and the practical steps for commercial solar installation in Nigeria’s largest city.
Identify Your DisCo Before Designing the System
Ikeja Electric and EKEDC have separate technical departments, separate customer portals, and can have different documentation preferences for pre-connection notifications. Confirming the serving DisCo at the start of the project avoids submitting documentation to the wrong entity — which adds 2–4 weeks to the approval timeline.

Building and Planning Permits in Lagos
Rooftop Solar on Existing Buildings
For rooftop solar systems installed on existing commercial or residential buildings using standard mounting systems (ballasted flat-roof mounting or hook-and-rail pitched roof mounting):
- LASBCA permit: Generally not required if no structural modification is made to the existing roof structure
- LASPPPA planning permit: Not required for solar on existing buildings within the existing building envelope
- Estate/development rules: For buildings within gated estates or commercial developments, check with the estate management or facility manager — some require prior approval from the estate management company before any rooftop work
Solar Carports and New Structures
For solar installations that involve constructing a new structure (carport canopy, pergola, free-standing ground-mount in a commercial compound):
- LASBCA approval: Required for new structural works on an existing developed plot
- Structural drawings: Required — a registered structural engineer must sign the design
- LASPPPA planning permit: May be required depending on structure size and location — contact LASPPPA at the relevant local government planning office
Ground-Mounted Commercial Systems
For large ground-mounted solar installations on commercial or industrial land:
- LASPPPA planning permit: Required for any development on land in Lagos State
- Environmental Impact Assessment: May be required for systems above a certain scale (confirm with Lagos State Ministry of Environment)
- Survey plan and title documents: Must accompany the planning permit application
DisCo Notification Process
For Systems Below 1 MW (Self-Generation Exemption)
For C&I solar systems that fall under the NERC self-generation exemption (below 1 MW, own consumption, own premises), formal DisCo approval is not required — but notification is strongly recommended for any grid-interactive installation. Notification protects the facility operator from DisCo enforcement action based on “unauthorised modification to the electricity installation” at the premises.
Submit to the relevant DisCo:
| Document | Notes |
|---|---|
| System description letter | Capacity (kW), inverter model, battery (if any) |
| Single-line diagram | Shows connection point to DisCo supply, all protection devices |
| NEMSA certificate (inverter) | For the specific inverter model installed |
| Protection settings table | Over/under voltage, over/under frequency, anti-islanding settings |
| Installer declaration | Signed by the licensed electrical contractor |
Timeline
Under NERC’s guidelines, DisCos must acknowledge a pre-connection notification within 10 working days. In practice:
- Straightforward commercial rooftop (< 100 kW): 10–15 working days
- Larger systems (100–500 kW): 15–25 working days
- Systems requiring DisCo feeder assessment: 20–35 working days
Lagos Solar Market Context

Commercial Solar Sizing for Lagos
Use Lagos-specific irradiance data for system design. Lagos is in the coastal south, with:
- Annual average peak sun hours: 3.8 – 4.2 PSH/day
- Worst month (July, during rainy season): 2.8 – 3.2 PSH/day
- Best months (December–February, dry season): 5.0 – 5.5 PSH/day
Size for Lagos’s Rainy Season, Not the Annual Average
Lagos receives 1,400–1,800 mm of rainfall per year, concentrated in April–July (long rains) and September–October (short rains). Irradiance drops significantly during these months. Size the PV array for the worst-month irradiance (July: approximately 3.0 PSH) rather than the annual average (4.0 PSH) — this ensures the system performs adequately during the rains when grid supply is also most unreliable.
Lagos State Energy Policy
Lagos State has enacted the Lagos State Electricity (Business and Consumer Safety) Law and a Renewable Energy and Energy Efficiency Policy that encourage distributed solar generation. Key provisions relevant to solar installers:
- Lagos State supports distributed generation as a strategy to reduce load on DisCo feeders
- No Lagos State-specific solar fee or levy beyond federal taxes
- Lagos State Ministry of Energy and Mineral Resources maintains a register of energy service companies (ESCOs) operating in the state — registration is not mandatory but can facilitate government contracts
- Lagos State participates in federal REA programs (Energizing Economies Initiative) for market and industrial cluster electrification
Lagos State does not have a separate net metering tariff or state-level solar subsidy. Federal NERC MYTO tariff rules apply.

Common Lagos-Specific Compliance Issues
| Issue | Typical Scenario | Resolution |
|---|---|---|
| Notification submitted to wrong DisCo | Installer checks postcode; it turns out to be EKEDC not IKEDC territory | Resubmit to correct DisCo; adds 2–3 weeks |
| No DisCo notification submitted | Grid-tied system energised without notifying DisCo | Submit retroactive notification; DisCo may inspect before confirming approval |
| LASBCA required for carport solar | Developer installs solar carport without building approval | Apply for regularisation with LASBCA — retroactive approval is possible but involves a penalty |
| Wrong irradiance data used | Annual average PSH used instead of worst-month | System underperforms during July–October rains |
| Equipment without NEMSA approval | Popular grey-market inverter brand specified | Source NEMSA-approved alternative; check nemsa.gov.ng before procurement |

Frequently Asked Questions
Do I need NERC to be involved in a commercial rooftop solar project in Lagos below 1 MW? No. Commercial solar below 1 MW for own consumption in Lagos falls under the self-generation exemption in the EPSRA 2005. NERC is not involved in the project approval — you notify the serving DisCo (Ikeja Electric or EKEDC), comply with NEMSA equipment standards, and follow LASBCA/LASPPPA requirements for any structural works. There is no NERC application, no permit, and no approval process from NERC for a standard C&I commercial rooftop project.
Does Ikeja Electric charge a fee for pre-connection notification processing? Both Ikeja Electric and EKEDC may charge an administrative fee for processing pre-connection notifications for commercial solar. As of 2026, fees reported by Lagos installers range from ₦50,000 to ₦200,000 depending on system size. Confirm the current fee with the DisCo at the time of submission — fees can change without public notice.
Is planning permission required for a solar system on a Lagos residential roof? For standard residential rooftop solar using hook-and-rail mounting (no structural changes to the roof), LASPPPA does not require planning permission in Lagos. For systems that involve significant structural modifications or new roof structures, consult LASBCA. For properties within controlled development areas or heritage zones, check with LASPPPA before commencing any roof work.
Can I install an off-grid solar system in Lagos without notifying anyone? A fully off-grid solar system (not connected to the DisCo grid in any way) does not require DisCo notification and does not require a NERC permit for systems below 1 MW for own use. NEMSA equipment approval is still required for the inverter and battery. If the installation involves any structural works on the building, LASBCA requirements apply.
