Kano is the commercial and industrial heart of northern Nigeria and one of the country’s most promising solar markets. The C&I solar opportunity in Kano is driven by three converging forces: DisCo grid supply that averages 5–8 hours per day in most commercial zones, diesel generation costs that reached ₦300–₦450/kWh after the 2023 fuel subsidy removal, and exceptional solar irradiance that ranks among the highest in Nigeria. The textile and manufacturing industries in Kano — historically the centre of Nigeria’s textile production — represent a particularly strong use case for solar-powered process heat and electricity.
The compliance framework in Kano combines federal NERC requirements with Kano State building approvals managed by the Urban Planning and Development Authority. This guide covers KEDCO-specific requirements for grid interconnection, KNUPDA permit requirements, the NERC net metering context for Kano, and the practical steps for commercial solar installation in Nigeria’s northern commercial hub.
Kano’s High Irradiance Does Not Eliminate Grid Backup Needs
Kano receives 6.0–6.6 peak sun hours per day, among the highest in Nigeria. However, KEDCO grid supply averages only 5–8 hours daily in commercial areas. Installers must design for full daily energy autonomy or diesel hybrid backup — not just grid-tied systems. A grid-tied-only design in Kano will leave the facility without power for 16–19 hours per day.
KEDCO Service Area and Coverage
KEDCO is one of Nigeria’s 11 privatised distribution companies, covering three states in northwestern Nigeria:
| State | KEDCO Coverage | Key Cities |
|---|---|---|
| Kano State | Full coverage | Kano, Bichi, Gaya, Rano, Wudil |
| Katsina State | Full coverage | Katsina, Daura, Funtua, Malumfashi |
| Jigawa State | Full coverage | Dutse, Hadejia, Gumel, Birnin Kudu |
KEDCO has approximately 1.5 million active customers across its territory. The company declared a “metering emergency” in 2024 with less than 5% of distribution transformers metered — the worst coverage nationwide. KEDCO has been deploying smart meters for high-value industrial customers and integrating them into an Advanced Metering Infrastructure network.
Kano Metropolis Specific Coverage
Within Kano metropolis, KEDCO coverage includes:
| Area | Typical Daily Supply Hours | C&I Solar Design Implication |
|---|---|---|
| Central Kano (Kofar Mata, Kurmi) | 6–10 hours | Hybrid recommended |
| Sabon Gari | 6–10 hours | Hybrid recommended |
| Bompai (Industrial) | 6–10 hours | Hybrid recommended |
| Nasarawa GRA | 8–12 hours | Grid-tied + battery viable |
| BUK Road | 6–10 hours | Hybrid recommended |
| Dawanau (Industrial) | 6–10 hours | Hybrid recommended |
| Sharada (Industrial) | 6–10 hours | Hybrid recommended |
| Challawa (Industrial) | 6–10 hours | Hybrid recommended |
KEDCO’s Dawanau Project, a ₦1.1 billion investment, commissioned a 33 kV line to increase power supply from 4 to 20+ hours daily for 400+ businesses in the Dawanau industrial cluster. This upgrade added 10 MW of capacity and is projected to generate ₦2.4 billion in incremental revenue for KEDCO in 2025.

KNUPDA Building Permits
Rooftop Solar on Existing Buildings
For rooftop solar systems installed on existing commercial or residential buildings in Kano using standard mounting systems:
- KNUPDA permit: Generally not required if no structural modification is made to the existing roof structure
- Estate/development rules: For buildings within industrial estates or commercial developments, check with the estate management — some require prior approval before any rooftop work
Solar Carports and New Structures
For solar installations that involve constructing a new structure in Kano:
- KNUPDA approval: Required for new structural works on an existing developed plot
- Structural drawings: Required — a registered structural engineer must sign the design
- Electrical designs: Required — signed by a registered electrical engineer
Ground-Mounted Commercial and Industrial Systems
For large ground-mounted solar installations on commercial or industrial land in Kano:
- KNUPDA building permit: Required for any development on land in Kano State
- Environmental Impact Assessment: May be required for systems above a certain scale — confirm with the Kano State Ministry of Environment
- Survey plan and title documents: Must accompany the permit application
- Certificate of Occupancy or land ownership proof: Required
KNUPDA commits to a 30-day processing period after fees are paid. The permit is typically valid for 2 years and is renewable. Application forms are available free at the KNUPDA office at 2 Durbin Katsina Road, Kano.
KEDCO Interconnection 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 KEDCO approval is not required — but notification is strongly recommended for any grid-interactive installation. Notification protects the facility operator from KEDCO enforcement action based on unauthorised modification to the electricity installation.
Submit to KEDCO:
| Document | Notes |
|---|---|
| System description letter | Capacity in kW, inverter model, battery if any |
| Single-line diagram | Shows connection point to KEDCO supply, all protection devices |
| NEMSA certificate (inverter) | For the specific inverter model installed |
| Protection settings table | Over/under voltage, over/under frequency, anti-islanding |
| Installer declaration | Signed by licensed electrical contractor |
Timeline
Under NERC guidelines, DisCos must acknowledge a pre-connection notification within 10 working days. In practice for KEDCO:
| System Size | Typical Timeline |
|---|---|
| Commercial rooftop under 100 kW | 10–15 working days |
| Larger systems (100–500 kW) | 15–25 working days |
| Systems requiring KEDCO feeder assessment | 20–35 working days |
NERC Net Metering Context for Kano
The NERC Draft Net Billing Regulations 2025 create a framework for prosumers in Kano to export excess solar power to the KEDCO grid. Key parameters:
| Parameter | Detail |
|---|---|
| Eligible capacity | 50 kWp to 5 MWp |
| Compensation | Credit-based at NERC-approved Injected Energy Tariff |
| Credit rollover | Indefinite — no expiration |
| Network safety limit | Total injection cannot exceed 30% of segment average load |
| Metering | Bi-directional smart meter required |
The 50 kWp minimum threshold means net billing in Kano is primarily a C&I proposition. Textile factories, manufacturing facilities, and large commercial buildings are the natural participants. Residential systems below 50 kWp remain self-generation exempt but cannot participate in net billing.
KEDCO, like all Nigerian DisCos, has a federal mandate to procure embedded generation. NERC’s 2024 directive requires KEDCO to source approximately 27 MW of embedded generation by 2025, with at least 50% from renewable sources. This creates an opportunity for large C&I solar developers to negotiate power purchase arrangements with KEDCO beyond simple net billing.
Kano Solar Market Context
Solar Resource
Kano has among the best solar resource in Nigeria:
| Metric | Value |
|---|---|
| Annual average peak sun hours | 6.0–6.6 hours/day |
| Dry season (November–May) | 6.5–7.0 hours/day |
| Rainy season (June–October) | 4.5–5.0 hours/day |
| Annual solar irradiation | ~2,400 kWh/m²/year |
| Best months | March–May |
| Worst months | July–August |
| Clear sky days per year | ~240 days |
Size for Kano’s Harmattan Season
Kano experiences intense harmattan conditions from December through February, with fine Saharan dust reducing PV output by 25–30% without cleaning. The dust coincides with the dry season when irradiance is otherwise at its peak. Establish a weekly panel cleaning protocol during harmattan and a monthly protocol during the rainy season to maintain system output.
C&I Solar Demand Drivers in Kano
Kano’s C&I solar market has unique characteristics:
- Textile industry: Kano was historically Nigeria’s textile capital. Solar can power process heat, dyeing, bleaching, and finishing operations. The planned $600 million Chinese textile investment in Kano specifically includes solar power allocation
- Manufacturing: Sharada and Challawa industrial areas host plastics, food processing, and metalworking factories with high energy demand
- Agricultural processing: Groundnut oil mills, hides and skins processing, and grain milling — all with significant thermal and electrical loads
- Cold storage: Perishable goods storage for the agricultural supply chain
- Educational institutions: Bayero University Kano and other institutions with large campuses
Solar Projects in Kano
Several large-scale solar projects are planned or operational in Kano State:
| Project | Capacity | Status |

Common Kano-Specific Compliance Issues
| Issue | Typical Scenario | Resolution |
|---|---|---|
| Site outside KEDCO territory | Address near Kaduna border turns out to be under another DisCo | Confirm with KEDCO customer service before design; re-submit to correct DisCo if needed |
| No KEDCO notification submitted | Grid-tied system energised without notifying KEDCO | Submit retroactive notification; KEDCO may inspect before confirming approval |
| KNUPDA permit required for factory solar | Textile factory installs ground-mount solar without building approval | Apply for regularisation with KNUPDA — retroactive approval is possible but involves penalties |
| Wrong irradiance data used | Annual average PSH used instead of worst-month | System underperforms during July–August rains and harmattan dust |
| Equipment without NEMSA approval | Grey-market inverter brand specified | Source NEMSA-approved alternative; check nemsa.gov.ng before procurement |
| Net metering eligibility misunderstood | 30 kW residential system designed for net billing | Net billing minimum is 50 kWp; system cannot participate; redesign as self-consumption only |

Frequently Asked Questions
Do I need NERC to approve a commercial rooftop solar project in Kano below 1 MW? No. Commercial solar below 1 MW for own consumption in Kano falls under the self-generation exemption in the EPSRA 2005. NERC is not involved in the project approval — you notify KEDCO, comply with NEMSA equipment standards, and follow KNUPDA 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 KEDCO charge a fee for pre-connection notification processing? KEDCO may charge an administrative fee for processing pre-connection notifications for commercial solar. Fees vary by system size and complexity. Confirm the current fee with KEDCO’s commercial services department at the time of submission — fees can change without public notice.
Is a building permit required for a solar system on a Kano residential roof? For standard residential rooftop solar using hook-and-rail mounting with no structural changes to the roof, KNUPDA does not typically require a building permit. For systems involving significant structural modifications or new roof structures, consult KNUPDA. For properties within industrial estates or controlled development areas, check estate management rules before commencing any roof work.
Can I install an off-grid solar system in Kano without notifying KEDCO? A fully off-grid solar system with no connection to the KEDCO grid does not require KEDCO 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, KNUPDA requirements apply.
